What Composer does
Composer is an AI-native automated investing platform that lets retail investors construct, backtest, and live-trade sophisticated hedge-fund-style strategies without writing a line of code. Users compose strategies by chaining conditional logic blocks ("if SPY is above its 50-day MA, buy QQQ; else hold cash"), which Composer translates into live brokerage orders. In October 2025, the company launched Trade With AI, a natural-language assistant that turns plain English ("build me a defensive momentum strategy with 10% max drawdown") into a fully backtested, deployable Composer symphony.
The platform supports US equities, ETFs, and crypto, with built-in tax-loss harvesting and automated rebalancing. Composer is registered as both an SEC-registered investment adviser and a broker-dealer, meaning users can execute strategies directly inside the product without bouncing to a third-party brokerage.
Who it's for
Composer targets sophisticated retail investors and traders who want quantitative strategies without the cost or complexity of building them in Python. The audience skews toward financially literate hobbyists, financial advisors, and small RIAs that use Composer as a strategy engine for client portfolios.
Pricing
Composer offers a free tier with backtesting, a Pro plan at $20-30 per month for live trading and advanced symphonies, and a Premium tier for advisors.
Team & funding
Composer was founded in 2020 by Benjamin Rollert (CEO), Ananda Aisola (COO), and Ronny Li (CDO). The company is headquartered in Toronto, Canada with US operations. Composer has raised approximately $16.7M across multiple rounds from investors including Left Lane Capital, First Round Capital, Golden Ventures, Alumni Ventures, and Not Boring Capital.
Position vs competitors
Composer competes with QuantConnect, Trade Ideas, and traditional robo-advisors like Wealthfront and Betterment. Its bet is that AI plus no-code strategy building can democratize quant trading, sitting in the gap between passive robo-advisors and hardcore Python-based quant platforms.
