Fractional GC vs BigLaw
Two completely different legal models. We break down when each one actually fits — and when paying BigLaw rates is burning runway you don't need to burn.

Book a Strategy Call →Should a startup hire a fractional GC or BigLaw?
Most early- and growth-stage startups should hire a fractional general counsel for ongoing legal work and reserve BigLaw for the specific moments that demand brand-name partner coverage — a competitive Series B led by a top fund, a $500M+ M&A exit, or a contested matter facing a top-tier opponent. Using BigLaw for day-to-day contracts and HR is overpaying for prestige you don't need.
How do the two models actually compare?
⚖️ Fractional GC vs BigLaw
| Feature | Fractional GC | BigLaw |
|---|---|---|
| Pricing model | Fixed monthly fee | Hourly billing |
| Predictable cost | ||
| Embedded in your business | ||
| Same attorney on every matter | ||
| Knows your product & customers | ||
| Handles day-to-day contracts | ||
| Brand-name partner for $500M+ M&A | ||
| Bet-the-company litigation | ||
| Turnaround on routine work | Hours to days | Days to weeks |
| AI-native workflows |
When does BigLaw actually make sense?
- Competitive Series B/C/D led by a top-tier fund that requires a name-brand firm on the cap table.
- Public-company M&A or a $500M+ exit with a sophisticated buyer-side firm.
- Cross-border financings, complex tax structuring, or CFIUS-sensitive transactions.
- Bet-the-company litigation against a Fortune 500 opponent.
- Regulated industry matters where partner-level credibility moves the regulator.
When fractional GC wins outright
- Seed through Series A AI and SaaS startups closing customer contracts every week.
- Founders who want one lawyer who knows the business — not a rotating cast of associates.
- Companies that need legal velocity matching engineering velocity.
- Anyone whose biggest legal risk is taking too long to ship, not the worst-case scenario.
- Teams that want fixed-fee predictability and zero billable-hour anxiety.

What's the difference between a fractional general counsel and a BigLaw firm?
A fractional general counsel is an embedded part-time attorney working on a fixed monthly fee with deep context on your business. A BigLaw firm is a project-based vendor billing hourly, often with multiple attorneys cycling through your matters. Fractional GCs are built for ongoing operational legal work; BigLaw is built for bet-the-company matters and capital-markets deals.
Is a fractional GC cheaper than BigLaw?
For ongoing operational work — contracts, employment, IP, vendor terms, AI risk — yes, almost always. Fixed-fee monthly retainers are predictable and scoped. BigLaw makes sense when you need brand-name partner coverage for a major financing, M&A, or litigation. The two can coexist; many startups use a fractional GC for day-to-day and BigLaw only for specific high-stakes matters.
Can a fractional GC handle a Series A or M&A deal?
Yes. Many fractional GCs handle priced rounds, term sheet negotiation, and mid-market M&A directly, often partnering with specialty firms for securities filings or international tax. For a $500M+ exit or a contested public-company deal, you may want BigLaw to lead — but a fractional GC stays embedded as the company-side quarterback.
Why do AI startups prefer fractional GCs over BigLaw?
AI startups move faster than BigLaw billing cycles allow. They need someone who knows the product, the customer pipeline, and the AI-specific risks (training data, model licensing, customer use clauses) without re-explaining the business every call. Fixed fees also protect runway; hourly billing creates an incentive to avoid asking for help.
When does it make sense to switch from a fractional GC to in-house counsel?
Typically after Series B, when legal volume justifies a full-time hire and the company has predictable revenue. Even then, many companies keep their fractional GC as a senior advisor or transition them into the in-house role. A good fractional GC will tell you when you've outgrown the model.
