Personal Investment Portfolio Tracker

Angel investors and early employees struggle to track non-public equity, cap tables, and investment performance across multiple companies using spreadsheets. Signed provides a centralized dashboard to manage equity positions, dilution, and valuations. Target users are angel investors, employees at multiple startups, and startup founders.

Private market portfolio tracking is having a genuine moment — the explosion of rolling funds, SPVs, and secondary marketplaces over the past few years has left thousands of angels and ex-employees holding illiquid equity across a dozen cap tables with no clean way to see the full picture. Carta is the closest incumbent, but it's CAP-table-management software sold to companies, not to investors — the investor-side experience is notoriously poor, which is the actual opening here. The $1k–5k/mo revenue band is plausible only if pricing targets serious angels or small family offices rather than early employees, who are unlikely to pay meaningful recurring fees for something they check twice a year. The biggest risk is data: non-public valuations are stale, self-reported, or simply unavailable, which means the dashboard will often show numbers users don't trust, killing retention regardless of how clean the UI is.
