The short answer
Start by counting your startup equity as part of your portfolio, because it is, and usually the largest and riskiest part. Once you see that, the job of the rest of your money becomes clear: it is ballast, not more of the same bet. In practice that means your liquid savings lean safer and more diversified than a typical portfolio would, heavy on broad index funds and safe fixed income, and light on more high risk, illiquid, or founder-adjacent bets (angel deals, crypto, another startup). You are already maximally exposed to upside through your company. The rest of your money is there to make sure a bad outcome is survivable.
