How the advisor equity calculator works

The calculator combines three inputs to produce a recommendation grounded in real data.

Stage-based baseline

Company stage determines the base equity amount. Pre-seed advisors take on more risk and earn more equity. Later-stage advisors join a de-risked company and earn less.

Time and involvement multiplier

How many hours per month the advisor commits affects the equity amount. A light-touch advisor at 1-2 hours per month commands about half the equity of someone embedded 10+ hours per month.

Value and uniqueness multiplier

Generic industry knowledge commands a discount. Deep domain expertise with a strong network or exceptional access commands a premium. This factor separates high-value advisors from resume-collectors.

Red flags to watch for

If an advisor approaches you asking for equity, be cautious. If they're collecting advisory positions across many companies, they're unlikely to give yours meaningful attention. If they can't articulate specific deliverables, they probably won't deliver much. See our full breakdown of when advisors aren't worth the equity.

Tie equity to deliverables

Standard time-based vesting means your advisor earns shares whether they deliver value or not. Roughly half of advisor relationships lose momentum after a few months. Tying vesting to specific milestones — introductions made, strategy sessions attended, concrete deliverables completed — keeps both sides accountable.
