Sydecar

Sydecar is a deal execution platform for venture investors that automates the operational back office of Special Purpose Vehicles (SPVs) — banking, compliance, KYC/AML, contracts, capital calls, and investor reporting — so syndicate leads, emerging fund managers, venture firms, and family offices can launch and administer SPVs, syndicates, secondary SPVs, and layered SPVs in hours instead of weeks. Sydecar also publishes a developer API (api-docs.sydecar.io) for programmatically creating and managing SPVs, subscriptions, and documents.

Sydecar publishes 1 API on the APIs.io network. Tagged areas include Company, Financial Services, Fintech, Venture Capital, and SPV.

Sydecar’s developer surface includes authentication, sandbox, engineering blog, pricing, signup flow, support, and 6 more developer resources.
