Setting up a sound legal foundation could be what saves a startup down the line. A missing founder vesting agreement, an unclear IP agreement, or a messy cap table can derail fundraising, spark co-founder disputes, or even kill an otherwise promising company before it has a chance to scale.
In this episode of Build Mode, host Isabelle Johannesen sits down with Kristina Subbotinai, founder and CEO of Lesxy and former startup attorney at Cooley, to break down the legal fundamentals every founder needs to get right. Kristina shares the four non-negotiable legal decisions every startup should make from day one, what investors actually look for during due diligence, how founders should think about negotiating control versus valuation, and why leverage is the key to getting better fundraising terms. She also shares real stories from the front lines of startup law, from co-founder breakups and investor negotiations to a founder who tried using ChatGPT to draft a merger agreement.
