In-house counsel are the lawyers employed by a company as full-time staff in the legal department. Outside counsel are the law firms and individual attorneys the company retains on a matter-by-matter or relationship basis. Most growing companies start with all outside counsel, hire their first in-house attorney somewhere between $5M and $50M ARR, and then progressively in-house more work as the legal department scales.
Structural differences
| Dimension | In-house counsel | Outside counsel |
|---|---|---|
| Employment | Salary + bonus + equity, full-time employee | Hourly billing or AFA; firm employee or solo |
| Client | One — the employer | Many — the firm’s portfolio |
| Privilege | Attorney-client privilege between in-house counsel and corporate client (with caveats) | Standard attorney-client privilege |
| Practice scope | Generalist within the company’s domain | Specialist within practice area |
| Day-to-day | Embedded in business decisions, fast access | Engaged for defined matters |
| Compensation | $200K-$700K+ for senior in-house; $1M+ for GC at large companies | $300K-$3M+ for partners; AFAs vary |
| Bar admission | Required in jurisdiction of operation; may have multiple | Required in jurisdiction of practice |
Both are licensed attorneys; the meaningful difference is the relationship to the client.
What in-house counsel typically does
Five main work types:
- Routine commercial. NDAs, vendor agreements, MSAs, customer contracts. Highest volume; lowest per-matter complexity.
- Strategic transactions. M&A (often with outside counsel co-leading), partnerships, investments.
- Employment and workplace. Employment agreements, severance negotiations, internal investigations, employment-law compliance.
- Regulatory and compliance. Industry-specific regulation, privacy, GDPR, AI policy, export controls.
- Litigation oversight. Coordinating with outside counsel on active litigation; making strategic and economic decisions.
What outside counsel typically does
Three main work types:
- Specialist expertise the in-house team doesn’t have. Specific regulatory areas (FDA, FCC, ITC), specialized litigation (patent, antitrust, securities), foreign jurisdictions.
- Capacity overflow. When in-house team is at capacity, routine work overflows to outside firms (though increasingly handled by AI augmentation rather than outside counsel).
- Litigation. Most companies don’t carry the litigation depth in-house; outside counsel handles court appearances, depositions, trial preparation, with in-house oversight.
The economic decision
The break-even calculation:
- Hiring an in-house attorney costs $300K-$500K all-in (salary + benefits + equity + tooling). At fully-loaded $400K/year, that’s ~$200/hour for 2,000 working hours.
- Outside counsel costs $400-$1,500/hour at large firms; $300-$700/hour at mid-market firms; $250-$500/hour at boutiques.
- Routine commercial work that takes 1,000+ hours/year is cheaper in-house. Specialized work that takes 100 hours/year is cheaper outside.
This drives the typical pattern: in-house team handles high-volume routine work; outside counsel handles low-volume specialist work.
How AI reshapes the in-house vs outside calculus
Three meaningful shifts:
- Routine work becomes nearly free in-house. Claude plus a paralegal handles work that previously required an in-house attorney, which previously required outside counsel. The cost of routine declines dramatically.
- Senior in-house leverage increases. A senior in-house attorney with AI augmentation produces 2-3x the output of the same attorney pre-AI. Hiring senior with AI looks better economically than hiring junior or sending more to outside counsel.
- Outside counsel concentrates on truly differentiated work. AFA-friendly routine work moves in-house; outside counsel keeps the high-stakes, high-judgment, deep-specialist work.
The net effect: in-house team headcount grows more slowly than work volume; outside counsel spend per matter increases for the matters that remain.
Common pitfalls
- Hiring junior in-house too early. A junior in-house attorney has the same overhead as senior but less judgment. Better to start with senior in-house plus paralegal plus AI; layer in junior later.
- Bringing too much in-house too fast. Specialist regulatory work in-housed at the wrong time produces malpractice exposure. Maintain outside-counsel relationships for genuine specialization.
- Treating in-house as cheaper at all volumes. In-house counsel’s true cost is high when matter volume is low; the marginal-cost framing favors outside counsel for occasional specialty work.
- Not investing in in-house infrastructure. Hiring an in-house attorney without CLM, matter management, and AI tools means the attorney spends time on plumbing instead of legal work.
