Lux Capital leads $6M seed round into Multiplier, an AI agent platform for fundamental equity hedge funds #
New York-based AI startup Multiplier has closed a $6 million seed round to build what it describes as a secure, firm-specific AI agent platform for fundamental equity asset managers, a segment it argues has been overlooked as larger multi-manager and systematic funds build their own in-house AI capabilities.
Lux Capital led the round, with venture participation from Y Combinator (Multiplier graduated from YC’s Spring 2026 batch), GoAhead Ventures, Rebel Fund, General Advance, Unpopular Ventures, and Amino Capital. Angel investors include Bridgewater Associates co-CIOs Greg Jensen and Karen Karniol-Tambour, Fortress Investment Group Chairman Pete Briger, DeepMind Chief Scientific Officer Jasjeet Sekhon, and Polygon CEO Sandeep Nailwal, among others. According to the company, Jensen wrote the first check into Multiplier before this round.
The startup was founded by three Princeton contemporaries: Ian McInnis, who serves as CEO and spent time as an investment associate at Bridgewater working on large language model projects under Jensen; Ben Finch, CTO and President, formerly a founding researcher at AI unicorn Sentient Labs; and Ryan Winkler, COO, who previously worked at StepStone Group. The three previously ran a student-managed hedge fund together that, according to the company, has beaten the S&P 500 each year it has operated. The company previously operated under the name WithAI.
Multiplier’s platform centers on coding agents deployed entirely on a client fund’s own cloud infrastructure, a design choice intended to address what the company says is the asset management industry’s core concern about proprietary research and decision-making processes leaking to third parties. The system is built to ingest a firm’s accumulated research, models, data sources, and workflows and make those accessible to AI agents for tasks including idea generation, company research, and post-trade analysis. Long/short investment manager Mercator Partners helped to incubate Multiplier ahead of the round.
The company argues that generic horizontal AI coding tools and narrow vertical finance software have both left fundamental equity shops ill-equipped for the current generation of autonomous AI agents. Multiplier plans to use the new capital to hire specialized engineering talent, procure high-performance compute capacity, and relocate its headquarters from San Francisco to Midtown East, New York City, to work more closely with its hedge fund client base.
