StartEngine is a Los Angeles based online private-market investment platform that lets everyday investors buy equity in startups and pre-IPO companies, and lets founders raise capital under Regulation Crowdfunding, Regulation A+ and Regulation D. The company operates StartEngine Capital, its FINRA-registered funding portal; StartEngine Private, a fund vehicle for later-stage pre-IPO companies; a secondary marketplace for trading eligible private shares; and StartEngine Secure, an SEC-registered transfer agent and cap-table management service sold to issuers on a published monthly plan. StartEngine publishes no public developer API, SDK, webhook catalog or developer portal - its public engineering output is an internal design-system npm scope, agent examples, and Ethereum security-token standards work (the ERC-1450 reference implementation).
