The problem
You earn $500K–$1.5M a year — most of it in equity. ISO exercise windows, AMT thresholds, NSO withholding, lockup expiry, tender offers. The decisions are genuinely hard.
Traditional advisors require AUM minimums you don't have yet. Robo-advisors can't model equity structure. And the smart moves — the ones that move the needle — require expertise you don't have time to develop.
Atrium fills the gap: expert-grade analysis, delivered proactively, without the advisor bottleneck.
What Atrium does
RSU vesting, ISO/NSO structure, exercise windows, cliff dates — tracked automatically.
Model ISO exercise scenarios and AMT exposure across IPO outcomes.
When something needs attention, Atrium tells you — before you have to ask.
Equity first, then taxes, savings, and wealth — one platform for the tech career lifecycle.
How it works
Link your equity dashboard or upload grant documents. Atrium ingests vesting schedules, grant types, and exercise prices.
The AI builds a real-time picture of equity value across IPO scenarios, estimates AMT exposure, and tracks decision windows.
When something requires attention, Atrium surfaces a clear, reasoned recommendation with analysis. You review and approve.
