●●SolidSolve My Problem

Equity tax calculator for non-finance people, competes directly with Carta and spreadsheets.

Strengths
  • Handles multi-company equity tracking in one dashboard without fragmentation
  • Tax scenario modeling with concrete take-home estimates reduces guesswork
  • Decision logging lets users track reasoning for future reference or disputes
Weaknesses
  • Crowded market: Carta, E*TRADE, eFunds already dominate equity management
  • Limited differentiation beyond clean UX; core problem (modeling) is math-heavy but solved

Post Description

I built Arcbase to make it easier for startup (and public company) employees to understand what their equity is actually worth.

Otherwise I feel like people often rely on rough guesses, overwrought spreadsheets, or prayer.

Arcbase is meant to be a relatively lightweight tool for non-finance people to actually get a handle on different scenarios, tax impacts, and package structures.

I’d really appreciate any feedback, especially from people who have dealt with this problem themselves.

TLDR Equity

Equity calculator with exit probability framing, but Carta already does this.
