API partner
We do not keep your cap table.
Carta, Pulley or AngelList Stack hold the ledger. Open.Raise holds the room. A commercial API lands after a partner agreement — this page records which rail you intend.
Carta
Cap table, 409A, issuance. The default US rail.
Pulley
Cap table and equity for early teams. Lighter than Carta.
AngelList Stack
Rolling funds and SPVs. Not a substitute for a priced round.
No live key is stored. Production is OAuth to the partner you named, scoped to your company. We never invent a cap table.
