How to Make a Million Through Startup Equity and RSUs
How a large share of tech millionaires actually got there.
How this path actually works
Companies pay part of your compensation in equity — RSUs (restricted stock units) at public companies, and stock options or shares at startups. This is how a large share of tech millionaires actually got there — and it is rarely discussed as a "path." It is also highly concentrated risk: most startup equity ends up worth zero.
The two flavors behave very differently. RSUs are shares that vest over time — when they vest, they are yours, taxed as ordinary income. Stock options are the right to buy shares at a strike price, which only has value if the share price rises above that strike.
The math
Option value at exercise:
The catch is what "fair market value" really is. For private companies, it is set by a 409A valuation — often far below what investors paid. And even a headline "$1B exit" can pay common shareholders (you) far less than expected, because of dilution and the liquidation preference stack: preferred investors get paid first, sometimes at a multiple, before common shareholders see a dollar.
RSUs are simpler: vest, sell, diversify. A $400,000 RSU grant over four years is $100,000/year of (taxable) income. Whether that becomes wealth depends on whether you diversify it or hold it all in your employer's stock.
The honest route
- Value the offer correctly — assume most private equity is worth $0 until it is liquid.
- Understand your vesting schedule and cliff before you count the equity as income.
- Sell RSUs on vest and diversify by default. This is the single most important rule.
- Know the tax treatment before exercising options — ISO exercise can trigger AMT.
- Do not concentrate your net worth in the company that also pays your salary.
What the data says
- The vast majority of startups fail or never reach a liquidity event — most startup equity is worth zero.
- RSUs at established public companies are a far more reliable wealth engine than startup options.
- The most common wealth-destroying error among tech employees is not diversifying — holding a concentrated position that later drops.
Who this works for — and who it doesn't
Works for: people in tech-adjacent roles at companies that grant meaningful equity, who understand the instruments and diversify by default.
Doesn't work for: anyone who counts illiquid paper as net worth, anyone who refuses to diversify, or anyone who stays at a job solely for equity that never liquidates.
Common ways people fail here
- Treating illiquid paper as net worth — it is not money until it is liquid.
- AMT surprises on ISO exercise — the tax bill can arrive before the liquidity.
- Not exercising before expiry — options have a clock.
- Refusing to diversify — job + portfolio in one company is correlated risk.
- Staying for equity that never liquidates — trading years for a lottery ticket.
Costs and taxes
RSUs are ordinary income at vest (withholding is typically automatic). Options: exercising ISOs can trigger AMT; an 83(b) election can be valuable but must be filed within 30 days of grant; and the eventual sale is taxed as capital gains or ordinary income depending on holding period. This is one of the most tax-sensitive areas on the site — professional advice is genuinely warranted.
Run your own numbers
Equity compensation is income — and like any income, it builds wealth only when invested. Model what your vested (and diversified) proceeds become. (A dedicated equity-comp calculator ships in a later version.)

Combining this with other paths
Equity compensation is really a turbocharged high-income career. The playbook is identical: convert the income into index investing as fast as it vests.
