What Composer does

Composer Technologies Inc. is an AI-native, no-code automated investing platform that enables retail investors to design, backtest, and execute systematic trading strategies across stocks, crypto, and options without writing code. Its core product translates natural-language descriptions of investment goals, risk tolerance, and strategy ideas into executable strategies via large language models, with a visual editor supporting custom weighting, conditional logic, and dynamic filtering, plus automated execution and portfolio rebalancing. The platform monetizes primarily through a flat-rate Trading Pass subscription with zero trade commissions and zero management fees, supplemented by a community marketplace (the Symphony Database) of more than 2,000 user-built strategies, a public API for developers, and IRA/Roth IRA retirement and business account offerings.

Brokerage execution, clearing, and settlement are handled through Alpaca Securities and Apex Clearing, with Composer Securities LLC operating as an SEC-registered, FINRA/SIPC-member broker-dealer subsidiary. Composer was founded in 2020 in Toronto, raised approximately $11 million in venture funding from First Round Capital, Golden Ventures, Alumni Ventures, Not Boring, and Left Lane Capital, and was acquired by SoFi Technologies in April 2026. Following the acquisition, the product was relaunched as 'Composer by SoFi' in June 2026, embedding AI-powered strategy creation into SoFi's super-app and gating advanced features behind a $10/month SoFi Plus tier, with a basic experience available free to all 14.7 million SoFi members. The company's go-to-market has evolved from product-led growth and community-led virality on a standalone app to distribution-led scale inside SoFi's fintech ecosystem.
