SoFi acquired Composer, an AI-powered automated investing platform, in a deal announced June 23, 2026, for an undisclosed price. Composer's technology — which lets people build and run algorithmic trading strategies using plain-English prompts — is now live inside the SoFi app as "Composer by SoFi," giving SoFi's 14.7 million members access to strategy tools that were previously the domain of hedge funds and quant desks.
Here's what Composer actually does, what SoFi paid (or didn't disclose), and why this deal matters more than its size suggests.
What is Composer?
Composer is a Toronto-based fintech founded in 2020 by Ananda Aisola, Benjamin Rollert and Ronny Li — a team that had previously worked on Ritual (food ordering) and Breather (flexible workspace). Before the acquisition, Composer had raised about $16.7 million across a handful of rounds, including a $4.25 million seed in 2021 and a $6 million round led by Left Lane Capital in 2022, with First Round Capital and Golden Ventures also on the cap table.
The product itself is a no-code trading platform. Users describe an investment idea in natural language, and Composer's AI turns it into a rules-based strategy — internally called a Symphony — that can be backtested against historical data and then automated for live trading. Rather than starting from scratch, most users pick from a library of more than 2,000 community-built strategies and customize from there. It works across taxable brokerage accounts and tax-advantaged retirement accounts, and supports both securities and crypto.
In effect, Composer packaged the workflow of a quant researcher — hypothesize, backtest, deploy, monitor — into a consumer product that doesn't require writing a line of code.
The deal
SoFi announced the acquisition on June 23, 2026, framing it as the launch of "Composer by SoFi" — an AI-powered investing platform built on Composer's technology and folded directly into the main SoFi app. The purchase price was not disclosed, which is typical for a deal of this size involving a private, venture-backed target being absorbed into a public acquirer's existing product.
A few things stand out about the timing and structure:
- It was SoFi's third acquisition in 2026, following its purchase of lending technology platform Peach and its acquisition of assets from UK retail investor platform PrimaryBid.
- Composer's existing brand and standalone product are being retired in favor of the "Composer by SoFi" integration — this is an acqui-integration, not a bolt-on subsidiary.
- Access is being extended through SoFi Plus, SoFi's membership tier, tying the AI investing feature to the company's broader monetization strategy rather than offering it as a separate paid product.
CEO Anthony Noto described the move as consistent with SoFi's pattern of "identifying innovative technologies and exceptional teams that can strengthen our ecosystem over time," calling Composer "one of the most innovative AI-powered investing platforms available to retail investors today."
Why SoFi bought Composer
SoFi's core financial super-app strategy is to keep members inside one product for banking, lending, and investing rather than losing them to specialized apps. Automated, AI-driven investing was a visible gap. Building a natural-language strategy engine, a backtesting pipeline, and a community strategy marketplace from zero would have taken years; buying a team that had already built and iterated on all three for four years compresses that timeline dramatically.
There's also a positioning angle. Algorithmic trading strategies have historically required either coding skill or access to institutional tools. By buying Composer instead of building a thinner version internally, SoFi gets a genuinely differentiated feature — not just another robo-advisor allocation slider, but a system that lets everyday users construct the kind of rules-based strategies quant funds run, then explains and automates them. That's a sharper answer to fintech competitors than incremental portfolio tweaks.
The deal also slots into a broader pattern of AI acquisitions in 2026 where the buyer isn't after a standalone AI company's revenue, but after a specific capability — in this case, natural-language-to-strategy generation — that plugs a hole in an existing product line. Composer's user base was a fraction of SoFi's, but the technology was the point.
What it means
For SoFi, Composer by SoFi is a bet that AI-assisted investing is the next feature war in consumer fintech, following the earlier scramble over commission-free trading and fractional shares. Whether it drives meaningful engagement will depend on whether mainstream SoFi users actually want to build trading strategies, versus simply wanting better default portfolios — a real open question given that most retail investors historically underperform when given more, not less, control over active strategy decisions.
For the AI-in-finance market broadly, the acquisition confirms that incumbents are choosing to buy natural-language financial tooling rather than build it, particularly when the target has already spent years refining backtesting accuracy and strategy UX — the unglamorous work that's hard to compress with a large language model alone. Composer's small funding total relative to its acquisition (a company that raised under $17 million landing inside a public fintech with millions of users) is also a reminder that in this cycle, exit value increasingly depends on how well a startup's technology plugs into a distribution machine, not just on how much capital it raised.
Expect more of this shape of deal through the rest of 2026: not mega-valuations, but disclosed-or-not acquisitions where a bank, broker, or fintech app buys a small AI team to close a specific product gap fast.
