If you have been using a law firm to handle contracts, employment questions, and governance as they come up, at some point the billing gets unpredictable and the advice starts to feel slow. A fractional general counsel offers a different model. So does bringing counsel in-house. Choosing between them is one of the more consequential operating decisions a founder makes, and it turns on stage, volume, and what you actually need from your legal function.
A fractional general counsel (also called an outside general counsel, or fractional GC) is a licensed attorney who provides ongoing legal services to a company on a retainer or flat-fee basis, functioning as embedded legal counsel without being a full-time employee. A traditional law firm handles legal work on a discrete, matter-by-matter basis. A full-time in-house general counsel is a salaried employee who serves the company exclusively.
The short answer is that none of the three options is universally right. A law firm makes sense when you have discrete, specialized needs and want to pay only when those needs arise. A fractional or outside general counsel makes sense when your legal work is recurring and you want embedded context and predictable cost. An in-house hire makes sense when you have enough legal volume and organizational complexity to justify full-time overhead. What moves the answer is your stage, how much legal activity you actually have, and how much unpredictable spend you can live with.
The in-house counsel market has grown fast. According to the Association of Corporate Counsel's population tracker, the number of in-house lawyers in the United States grew from roughly 78,000 in 2008 to about 145,000 in 2024, a growth rate that outpaced law firms by more than 20 percentage points. That growth tells you something real about where companies are placing their legal function over time. But population data does not tell you when the switch makes sense for your company, and the decision is not the same at $2 million in revenue as it is at $25 million.
This article walks through all three models side by side: what each one is, how the cost structures work, what the decision levers are, and how to think through the choice by stage. It is written for founders, CEOs, COOs, and CFOs of growth-stage companies who are trying to figure out what legal coverage makes sense at their current scale. It is not written for in-house legal teams evaluating vendors; that is a different question.
What is the difference between an outside general counsel and a regular law firm?
The core distinction is episodic versus embedded. A traditional law firm handles defined matters when you bring them a problem. Each engagement starts with a new briefing. The firm does not carry your institutional context forward between projects; they do not know your cap table, your customer base, your recurring contractual risks, or the employment issues you have been managing unless you re-explain every time. You pay per matter, or per hour, or both, and the bill at the end of each month depends on how much activity came up.
An outside general counsel, sometimes called a fractional GC, works differently. The engagement is typically structured as a monthly retainer or flat fee, and the attorney functions as an embedded extension of your leadership team. Over time, an outside GC builds the institutional knowledge a law firm never accumulates: they know your product, your vendor relationships, your recurring contract issues, your employment practices, and your governance structure. When a question comes up, the answer is faster because the context is already there.
The Kruze Consulting blog, written from the perspective of a startup CFO advisory firm rather than a law firm, describes outside GC responsibilities as covering commercial contract review and negotiation, employment and HR guidance, IP strategy and ownership documentation, corporate governance, and fundraising support. The differentiator it highlights is continuity: proactive oversight by someone who already knows the business, rather than an episodic specialist you have to brief from scratch. That framing captures the functional distinction accurately.
An in-house general counsel is a full-time employee. They handle everything an outside GC would handle, plus they are present for every leadership discussion, every board meeting, and every strategic decision. The trade-off is cost: you are paying for full-time availability regardless of whether the legal workload justifies it on any given week.
Do I need a fractional general counsel or a law firm for my startup?
The honest answer depends on two variables: the volume of your legal activity and the type of that activity. Law firms are well suited for discrete, high-stakes matters where you need specialized depth that a single generalist attorney may not carry. M&A work, complex IP litigation, regulatory enforcement defense, and sophisticated debt financing are examples where a firm's specialization and bench depth are genuinely valuable. You should expect to use outside specialists for these regardless of whether you have a fractional GC or not.
The law firm model starts to work against you when your legal needs become recurring and repetitive. Drafting and negotiating commercial contracts, reviewing employment agreements, maintaining corporate governance records, answering compliance questions, and supporting fundraising cycles are all work that requires institutional knowledge of your business. When you bring a law firm into each of those situations without that context, you pay both the hourly rate and the ramp-up cost every time. You also get billing variability that makes legal spend hard to forecast.
A rough decision threshold that comes up in startup advisory circles is around $15,000 to $20,000 per month in law firm spend on recurring work. When episodic billing starts landing in that range consistently, a flat-fee retainer arrangement often becomes more cost-effective, and the retained attorney accumulates the institutional knowledge that makes subsequent advice faster and more accurate. That threshold is a starting point for the analysis, not a formula. Your volume, the complexity of your recurring work, and the market will determine the actual number.
The two models are not mutually exclusive, either. Many growth-stage companies maintain both: an outside GC handles day-to-day legal oversight and routine contract work, and a law firm handles specialized matters that fall outside the outside GC's scope. That hybrid approach is common from Series A through Series B, and it is often more cost-effective than trying to get a single model to cover everything.
When a law firm is the right choice, the selection signals for a startup are different from the selection signals for an established company. Look for a firm with demonstrated early-stage company experience (not just general corporate work), attorneys who are comfortable with SAFE instruments and startup equity mechanics, and billing practices that include flat-fee options for formation and fundraising work. A firm that only offers hourly billing for routine startup work is a signal that its practice is not optimized for the volume and cost structure of early-stage clients.
What does outside general counsel actually do for a growth-stage company?
The clearest way to answer this is to describe a typical week. The scope question is not really about a formal job description. It is about what actually comes up for a growth-stage company and who handles it.
On the contracts side, an outside GC reviews and negotiates commercial agreements: customer contracts, vendor MSAs, SaaS subscriptions, NDAs, and partner agreements. AI vendor agreements increasingly sit in this pile, and the standard commercial MSA often does not cover what a company needs on data use, output ownership, and indemnification (the clauses worth redlining). They maintain a standard form library so the company is not starting from scratch each time, and they know which terms your company has accepted historically and which ones you push back on. They also manage the ongoing contract portfolio, which means knowing when key agreements expire, what obligations are coming due, and which counterparties are likely to push for renegotiation.
On the employment side, an outside GC drafts and reviews offer letters, employment agreements, equity grant documents, and separation agreements. They advise on policy questions (a handbook update, a contractor classification question, a termination decision) and flag when a situation creates legal risk that needs to be managed carefully. Employment questions have a way of arriving without warning, and having an attorney who already knows your people and your history matters when that happens.
On governance, an outside GC maintains corporate records, prepares board consents and resolutions, manages cap table documentation, and coordinates equity grant compliance. For companies that have taken outside capital, this is not optional. Investor agreements typically impose governance obligations, and the documentation has to stay current. During a fundraising process, an outside GC supports the company on term sheet review, assists with the legal closing process, and works alongside the company's attorneys and investors' counsel to get the transaction done.
The common thread across all of this is proactive oversight. An outside general counsel covers contracts, employment, governance, and fundraising support for a growth-stage company on an ongoing retained basis, rather than waiting to be called when a specific problem arises. They review contracts before they are signed, not after a dispute surfaces. They flag employment risks before a termination, not after an EEOC charge lands. That posture is the functional difference between having embedded legal coverage and relying on episodic legal help.
How much does an outside general counsel cost for a startup?
Cost structure is where the three models diverge most sharply, and it is important to be clear about what is and is not a hard number.
For full-time in-house counsel, there is authoritative federal data. The U.S. Bureau of Labor Statistics Occupational Employment and Wage Statistics program reports a mean annual wage of $185,840 for lawyers across all settings as of May 2025, across an employment base of approximately 754,500 jobs. That is the national mean; it reflects the full range from government and nonprofit employment through BigLaw and in-house roles. For in-house counsel specifically at growth-stage companies, the ACC 2025 Law Department Compensation Survey provides more granular benchmarks: CLOs and general counsel at companies with more than $5 billion in revenue earn 44% more base salary and 173% more total compensation than their counterparts at companies with under $1 billion in revenue. That spread tells you how sharply compensation scales with company size and complexity. At the seed stage, market estimates from legal staffing sources suggest a first in-house hire might carry a base salary in the $135,000 to $160,000 range, though the BLS national mean is the more authoritative anchor. Add benefits (typically 20% or more of base) and early-stage equity, and the fully loaded annual cost of a first in-house counsel commonly runs $160,000 to $250,000 or more.
For fractional and law firm arrangements, there is no comparable authoritative survey. Market-color figures from legal technology and staffing vendors describe fractional GC retainers in a range that varies widely by market, provider experience, and engagement scope; hourly fractional rates are similarly variable. These are market estimates, not survey averages, and the actual cost depends on the specific arrangement. Similarly, law firm hourly rates for transactional work vary substantially by firm, market, and matter type; published estimates from vendor and advisory sources describe a range that reflects the low end of major-market transactional practice, not a reliable industry average. The practical point is that law firm billing on recurring work is difficult to forecast month to month, while a flat-fee retainer arrangement (whether with a fractional GC or another outside arrangement) provides fixed, predictable cost regardless of how many questions come up.
The BLS also gives founders in the Mid-Atlantic some regional context. The Baltimore-Columbia-Towson metro area occupational wage data (May 2024) shows legal occupations averaging $60.74 per hour. That regional figure is an average across legal roles and employment types, not a benchmark for any specific engagement structure, but it reflects the labor-market context for legal talent in the DMV corridor.
On the flat-fee versus hourly question: a flat-fee retainer arrangement is generally worth it for an early-stage company once recurring legal needs are consistent enough that variable billing creates meaningful monthly variance. The value is not just cost reduction. It is cost certainty: a flat-fee arrangement allows a CFO to budget legal spend the same way they budget any other fixed operating cost. For a company spending more than $10,000 to $15,000 per month on episodic legal work, the predictability alone is often worth the retainer, independent of any per-hour comparison.
When should a startup hire its first general counsel?
Startup advisory sources consistently point to two trigger conditions for the full-time in-house GC hire: legal workload that justifies 40 or more hours of attorney time per week, and annual revenue approaching or exceeding $20 million. Before either of those conditions is met, most growth-stage companies are better positioned to use a fractional or outside GC arrangement.
The stage-based logic works roughly as follows. At the pre-seed and seed stage, legal needs center on entity formation, IP ownership documentation, founder agreements, and SAFE instruments. A law firm relationship is typically adequate at this stage, with the caveat that founders should use firms that understand early-stage company work rather than general-practice firms that are learning alongside them. The legal spend at this stage is episodic and relatively manageable.
At Series A and into Series B, the legal workload expands significantly. Commercial contracts multiply as the company lands customers. Employment documentation becomes more complex as the headcount grows. Cap table management requires ongoing attention as equity grants are made and amended. Fundraising cycles impose legal closing requirements. A fractional GC arrangement starts to pay for itself at this stage by providing institutional continuity across all of these workstreams, rather than re-briefing a law firm for each one.
By Series B and into the growth stage, many companies are maintaining both a fractional GC and external law firm relationships for specialized work. The question of when to hire full-time is primarily a volume question. If the outside GC is billing at near-full-time hours consistently, or if the legal function has grown to include team management, board-level strategic partnership, and complex multi-jurisdiction compliance, a full-time hire starts to make financial and operational sense. The ACC 2025 survey's finding that 77% of in-house counsel had prior law firm experience is a useful reminder that the full-time hire is typically a senior, experienced attorney, and the salary expectations reflect that.
How do startups handle legal work before they can afford a full-time lawyer?
The progression is fairly consistent across growth-stage companies. Early on, founders tend to use a law firm for formation and fundraising and handle everything else themselves. That works until it does not: the first time a customer pushes back hard on contract terms, or the first time an employment situation goes sideways, the gap in legal coverage becomes expensive very quickly.
The middle path is a fractional or outside GC arrangement. This gives the company ongoing legal coverage, institutional knowledge, and cost predictability without the overhead of a full-time hire. The ACC population data suggests this model has grown substantially: the in-house counsel population roughly doubled between 2008 and 2024, and a significant portion of that growth reflects companies formalizing their legal function at earlier stages than they did a generation ago.
What founders sometimes underestimate is the cost of the gap itself. Contracts signed without legal review, employment decisions made without legal input, and governance lapses that surface in due diligence all carry price tags that typically exceed what ongoing legal coverage would have cost. A fractional general counsel is specifically designed to close that coverage gap at a stage where the company cannot yet justify a full-time headcount addition.
Fractional GC vs hiring an in-house lawyer: which is cheaper for a seed-stage startup?
At the seed stage, a fractional arrangement is almost always less expensive on a cash basis. The math is straightforward: a full-time in-house hire at a seed-stage company carries base salary, benefits, and equity, with fully loaded annual costs commonly in the $160,000 to $250,000 range or more depending on the candidate's experience level and market. A fractional arrangement covers recurring legal needs at a fraction of that cost, with the flexibility to scale hours up or down as needs change.
The comparison gets more complicated as the company scales. If legal volume grows to the point where the fractional attorney is working close to full-time hours, the cost per hour of a retainer arrangement can approach or exceed what a full-time salary would cost for the same output. The practical test is whether the legal workload is consistent enough to justify full-time overhead, or whether it is still variable enough that a fractional model provides the right cost structure.
There is also a flexibility consideration. A full-time hire is a headcount decision with real costs to reverse; if the legal workload does not materialize as expected, you have taken on fixed overhead that is difficult to reduce. A fractional arrangement can be renegotiated, paused, or transitioned more readily. For a seed-stage company where the business model is still proving out, that flexibility has real value.
The three models side by side
| Model | Fractional / Outside GC | Traditional Law Firm | Full-Time In-House Counsel |
|---|---|---|---|
| Typical engagement | Monthly retainer or flat fee; embedded in leadership team | Episodic; matter-by-matter billing | Full-time employee; salary and equity |
| Cost structure | Fixed monthly cost; scales with engagement scope | Hourly or matter-based; variable monthly spend | Fixed annual salary plus benefits and equity |
| Cost range (market estimates) | Varies widely; no authoritative survey. Monthly retainer arrangements are the typical structure. | Varies widely; no standard rate card. Market estimates from advisory sources describe significant ranges by firm type and market. | Mean annual wage $185,840 (BLS OEWS, May 2025). Fully loaded cost at seed stage commonly $160,000 to $250,000+; higher at later stages per ACC 2025 survey data. |
| Best fit by stage | Seed through Series B (and beyond for companies with lower sustained legal volume) | Any stage for specialized or one-off matters; early stage for formation and first fundraise | Series B+ where legal workload justifies full-time overhead, typically $20M+ revenue run rate |
| Institutional knowledge | High; builds over time as the GC learns the business | Low; brief from scratch each matter | Maximum; embedded in all business decisions |
| Speed on routine questions | Fast; already knows the business and context | Slow; requires briefing and response cycle | Fastest; immediately available |
| Access to specialized expertise | Via network; fractional GC can coordinate specialist counsel when needed | Direct; firms have specialist attorneys across practice areas | Limited to one attorney's skill set unless a full legal team is built |
| Cost predictability | High; fixed retainer | Low; each matter adds unknown cost | High; fixed annual cost |
| Flexibility to scale | Medium; retainer can typically be renegotiated as needs change | High; pay only for what you use | Low; full-time headcount is difficult to reduce |
One note on the hybrid model that the table does not fully capture: many growth-stage companies use an outside GC for ongoing oversight and a law firm for specialized matters in parallel. That is not a failure to choose; it is often the right answer. The outside GC manages the day-to-day legal function and coordinates specialist counsel when the matter warrants it, which keeps the specialist bill predictable (the outside GC scopes the matter) rather than open-ended (the specialists write their own scope).
Decision Framework
These five questions are designed for a founder or leadership team to work through internally. They are not a formula for the right answer; they are the questions that will surface what matters most for your specific situation.
1. What is your current monthly legal spend, and how predictable is it? If you are spending $10,000 to $20,000 per month or more on episodic law firm work and the spend varies significantly month to month, that pattern is a signal that your legal activity has become recurring enough to warrant a different cost structure. If your spend is low and occasional, the law firm model may still be appropriate.
2. How much of your legal work is recurring versus specialized? Recurring work (contract negotiation, employment documentation, governance maintenance, compliance questions) is where institutional knowledge pays off. Specialized work (M&A, IP litigation, regulatory enforcement, complex debt) is where a firm's deep expertise is worth the episodic billing. If most of your current legal activity is in the first category, embedded legal coverage is likely more efficient.
3. Does your legal counsel know your business, or do you have to re-brief them every time? If you are spending significant time on every engagement explaining context that your attorney should already know, you are paying for a knowledge gap as well as legal work. That is the clearest operational signal that a retained arrangement would be more efficient.
4. What stage triggers are on your horizon? Fundraising, significant hiring, international expansion, regulatory scrutiny, or material contract negotiations all create legal needs that are easier to handle with embedded legal coverage than with episodic counsel. If any of those are on your 12-month roadmap, the question of legal model is also a planning question.
5. Can your company justify full-time legal overhead? A full-time in-house hire is the right answer when your legal workload is consistently high enough to warrant a full-time attorney, your revenue and complexity support the salary and benefits, and your company has reached a scale where the legal function needs to be embedded in every major decision. If you are not there yet, that is a useful answer too. It means the fractional model should be serving you well for now.
Audience-Specific Implications
For Founders and CEOs
The model you choose sets the legal function's posture for the next two to three years. A law firm relationship kept past its useful stage means you are paying for ramp-up time on every matter and getting advice that lacks context. A fractional GC brought in too early means you are paying a retainer for work that could be handled episodically at lower cost. The timing question is operational, not just legal: it turns on how much recurring legal volume you actually have, not on what stage you nominally are in. The practical step is to pull three to six months of law firm invoices, categorize the work by type (recurring vs. specialized), and assess whether the recurring work would be better served by a retained arrangement.
For CFOs and Finance Leads
The cost comparison between models is only meaningful when it is fully loaded. A fractional GC retainer should be compared against the total law firm spend on equivalent recurring work, not against the quoted hourly rate. A full-time in-house hire should be compared against total legal spend (retainer plus specialist fees) at fully loaded cost (salary, benefits, equity), not against salary alone. The BLS mean annual wage of $185,840 for lawyers is a useful national baseline for the in-house comparison; the ACC 2025 survey provides the stage-adjusted benchmarks. Budget predictability is also a real variable: episodic firm billing creates variance that a flat-fee retainer eliminates, and that variance has a planning cost that does not show up in the per-hour comparison.
Practical Takeaways
- Pull three to six months of law firm invoices and categorize the work. Sort each matter into recurring (contracts, employment, governance, compliance questions) versus specialized (M&A, IP litigation, regulatory enforcement, financing). If recurring work represents more than half of the total spend, the institutional-knowledge and cost-predictability case for a fractional arrangement is worth running the numbers on.
- Run the fully loaded cost comparison before deciding on a full-time hire. Use the BLS OEWS mean annual wage ($185,840, May 2025) as your salary anchor, add 20% or more for benefits, and factor in equity at your current stage. Then compare that total against your current combined legal spend (retainer plus specialist fees, if applicable). The comparison should be apples to apples: all-in cost on both sides.
- Check whether your current legal counsel knows your business or has to be re-briefed. If you are spending time on every matter explaining context a retained attorney would already have, that ramp-up cost is real money. Estimate it: how many hours of your team's time goes into legal briefing each month, and what is that worth? Factor it into the model comparison.
- Identify what is on your 12-month legal roadmap before you decide. If you have a fundraising round, a material commercial contract negotiation, a hiring push, or any regulatory exposure on the horizon, those create legal needs that are easier to handle with embedded coverage than with episodic counsel. The model decision is also a planning decision, and it is easier to make the switch before the activity peaks than during it.
- Understand the hybrid model before assuming it is a compromise. A fractional GC who manages the day-to-day legal function and coordinates specialist counsel for complex matters is not a second-best option; for many Series A and Series B companies it is the most cost-effective structure available. The key is that the outside GC scopes and manages the specialist engagement, which prevents the specialist from running the scope independently. That distinction alone can significantly affect what you spend on outside counsel.
- If you are considering a fractional GC, ask specifically about scope and availability. Fractional arrangements vary widely in what they include. Ask what is covered in the retainer, how after-hours or urgent questions are handled, how specialist referrals work, and how the relationship transitions if your legal volume grows significantly. Those structural questions surface more about fit than any rate discussion will.
- Do not defer the model decision until a legal problem surfaces. The companies that get the most value from embedded legal coverage are the ones that engaged before the contract dispute, before the employment termination, before the investor due diligence request. The fractional or outside GC model is most valuable as a risk-prevention function, not as a crisis-response function. The cost of waiting is almost always higher than the cost of the retainer.
Closing Perspective
The legal model question is really a question about how your company makes decisions. A law firm relationship, however good, treats legal as a specialist function you call when something breaks. A retained legal arrangement, whether fractional or full-time, treats legal as an input to decisions before they are made. Those are different postures with different risk profiles, and the difference shows up most clearly in the contracts you did not sign, the employment decisions you handled cleanly, and the fundraising process that closed without surprises.
From what I see in conversations with growth-stage founders, the most common mistake is not choosing the wrong model. It is staying in the wrong model too long because the transition feels complicated. Switching from episodic law firm use to a retained arrangement does involve some upfront work: onboarding, knowledge transfer, getting the forms and processes in order. But that work is finite. The ramp-up cost of a retained arrangement is a one-time investment; the ramp-up cost of episodic counsel is paid over and over, on every matter, indefinitely.
The right time to evaluate this is before your legal volume peaks, not after it already has. If the indicators above are pointing toward a change, the question is not whether to make it. It is how to structure the transition so the new arrangement is running smoothly by the time the next big legal moment arrives.
