What does a great startup lawyer actually do for a UK founder?
A good startup lawyer pays for themselves on the first contract negotiation. A great one pays for themselves before the round even closes. UK founders chronically under-invest in legal at the wrong points and over-invest at others. The Law Society's 2026 startup-services data shows founders spend 3.8x more on legal in year three than in year one — usually fixing avoidable year-one mistakes.
The legal mistakes that hurt most are the early ones: badly structured cap tables, founder vesting that doesn't kick in, IP not properly assigned from contractors.
A great startup lawyer is responsive (replies within hours), opinionated (tells you when you're wrong), and commercial (knows when to push back vs. when to sign).
For UK lawyers wanting startup mandates: founders want fixed-fee SEIS/EIS, fixed-fee EMI, and a named partner who'll take a Friday-afternoon call.
“A good lawyer tells you what you can do. A great one tells you what you shouldn't.”
