Show HN: Arcbase – understand what your startup equity is worth

https://arcbase.co
2•Elberonian•1h ago
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.

If it’s useful, happy to give HN folks 6 months free. You should automatically go into a free trial at sign up but the code ARCFRIEND will also work to give you 6 months free beyond that.

You do need to create an account with email, but no credit card needed.

Feedback welcome, especially on what’s confusing or missing. My gut right now is that it still feels a little too complicated?
