The problem with equity compensation

Generic tools fail you

Mint, Personal Capital, and spreadsheets have zero understanding of ISOs, AMT, lockup periods, or concentrated stock positions. You're flying blind.

Advisors are inaccessible

Firms that understand equity compensation, like Compound and Harness, charge $3,000–$50,000/year. Most employees can't afford real guidance at the moment they need it most.

The stakes are enormous

A single wrong decision around ISO exercise timing, lockup sales, or CA tax planning can cost you hundreds of thousands of dollars. The window to act is narrow.
