What your AI assistant can do
Every tool is a read-only view of your angel investing world on Signed — portfolio performance, cash flows, companies, notes, and pitches. Nothing gets written, moved, or deleted.
Portfolio performance
Portfolio value and returns — IRR, TVPI, DPI — across companies, funds, and SPVs.
Value over time
Chart your portfolio's history — total value, invested capital, and realized returns at any point.
Cash flows & distributions
Every buy, SAFE, sale, and distribution — "show me every distribution I got this year."
Tax-time answers
Pull the year's sales and distributions, with QSBS flags, when it's time to file.
Portfolio companies
List, search, and look up the startups you've invested in, with your notes and history.
Notes & diligence
Search back through your own notes on companies, pitches, and founders.
Pitch triage
See what's landed in your pitch queue and dig into individual submissions.
Investor network
Public investor profiles from the directory, plus who you follow and who follows you.
