For most US tech startups, it's basically Delaware C Corp, figure out your 83b / QSBS / SAFE, and later, R&D Tax Credit. If profitable early, and not spending back 100% on growth, add in some treasury management setup. The rest should be growing the pie and not going out of business.<p>Part of that is saving you time by getting a book keeper and accountant who will walk you through minor additions to this stuff. I see folks spend time on weirder ideas like Trusts, and they are time sucks away from what they should be doing, and if/when M&A hits, a lot of nonsense to unwind. I rather spend that time getting an extra $50k-$100k customer that raises the valuation $500k-$1M.<p>The one shift I've seen is QSBS hijinks at state levels have led to founders leaving SF/NYC/etc as their co's hit Series B+ and and they care less about local VC + tech ecosystem proximity. Less true of unprofitable companies reliant on the next round for keeping the lights on.
