Already scaling, not starting
Most firms that call themselves startup lawyers stop being useful somewhere around the seed round. The work changes after that, and so does the risk.
At the scale-up stage, the questions are different. Your second-round investor wants protections that your first-round investor never asked for. You have a board now, and it needs papers it can actually rely on. Key staff are asking about equity and the answer has tax consequences. The contracts you signed at ten customers do not work at two hundred. Somebody has approached you about acquiring the business and you have no idea whether your house is in order.
We do that half of the work too, which is the half that decides what the company is eventually worth.
