I work in finance. One of my clients is looking to raise their first big round of capital, at a really nice valuation, with a product that might likely take them to >$1b in revenue. Anyway, the original founders had differentiated opinions also in terms of the product offering, so one of the founders was bought out a few years ago for mid 7 figures or something like that. I predict that their decision to leave the company due to disagreement on strategy will probably cost this person a high 8 figure payday (best case scenario) or perhaps a 9 figure payday (worst case scenario). Just wanted to provide this anecdote as one possibility of what could happen. It’s not an easy decision but ultimately you should do what you think feels right, but don’t bee overly myopic in your decision making. Also, don’t think that the only options are stay (don’t sell any equity) or leave (sell 100% of equity), you can fall somewhere in between and have some skin in the game for potential upside.
