In a theoretical world, I would make the tax progressively larger after &quot;financial independence&quot; has been reached - either via step functions (every 1x over financial independence, 50% of the remainder is taxed) or some kind of parabola.<p>This may be too hard to explain clearly (even progressive commission plans are hard to understand!) so perhaps I would just settle for a higher tax rate.<p>My thought is if the founders want to make multi-millionaires out of the later engineers, a 50% tax will only do this in the extreme (10+ billion exit) cases.  And in those cases, the founders will be billionaires themselves.<p>I&#x27;m assuming that Financial Independence is a large number (somewhere between 10 and 50 million) and that afterwards, the founders are in it &quot;to build something great&quot; rather than to keep score.  Otherwise, you wouldn&#x27;t consider the plan.<p>This isn&#x27;t meant to diminish Detour.  It&#x27;s kind of like making fun of the first company to give equity just because equity can go down in value - I&#x27;m just making suggestions on a groundbreaking idea.
