## Frequently Asked Questions

### When does the AI startup equity typically break even compared to Big Tech RSUs?
Based on standard venture trajectories, the break-even crossover typically occurs around Month 36, assuming a successful Series B or C financing round with a valuation markup that offsets the initial salary discount.

### What happens to my unvested options if the AI startup goes under?
Unvested options expire immediately upon termination or company dissolution, and vested options typically must be exercised within 90 days of departure, risking total loss of the upfront salary sacrifice.

### How do taxes impact the decision between RSUs and startup options?
Big Tech RSUs are taxed as ordinary income upon vesting. In contrast, startup NSOs or ISOs offer potential long-term capital gains tax treatment if held properly after exercise, though ISOs carry Alternative Minimum Tax (AMT) risks.
