A team of ex-Bridgewater Associates employees is betting artificial intelligence can crack open one of finance's most entrenched monopolies.
Multiplier, a New York startup building AI tools for hedge funds, closed a $6 million seed round led by Lux Capital, the company announced August 26. The financing drew an unusual roster of backers for an early-stage enterprise software company: alongside venture firms Y Combinator, GoAhead Ventures, Rebel Fund, General Advance, Unpopular Ventures and Amino Capital came heavyweight investors from across finance and technology.
Greg Jensen, co-chief investment officer at Bridgewater Associates, wrote the first check. He was joined by his Bridgewater counterpart Karen Karniol-Tambour, Pete Briger of Fortress Investment Group, Jasjeet Sekhon of Google DeepMind, Sandeep Nailwal of Polygon, and Kaz Nejatian of Opendoor. The mix suggests Multiplier has caught attention beyond the typical venture crowd.
From Bridgewater to Bloomberg's Backyard
Legally registered as WithAI Research Inc., Multiplier builds custom AI coding agents for fundamental equity hedge funds. The platform deploys what the company calls "firm-specific" agents, trained on a fund's proprietary workflows and data, all running inside the client's cloud infrastructure with zero data retention during inference.
The founding team brings serious credentials from both finance and artificial intelligence. CEO Ian McInnis built large language model investment systems at Bridgewater after graduating from Princeton with perfect 4.0 GPAs in pure mathematics, applied mathematics, and humanities, according to the company. CTO Ben Finch was a founding researcher at AI firm Sentient and won Princeton's electrical and computer engineering top thesis award. COO Ryan Winkler worked at StepStone, where he allocated $600 million across secondaries and co-investments.
Before Multiplier even had a product, the startup was incubated by Mercator Partners, a long-short fundamental manager, according to an August 10 company blog post. The company went through Y Combinator's batch program and has since moved quickly to convert early interest into revenue.
Six Funds Already Signed On
Multiplier now counts six hedge funds as customers, per the company's Y Combinator profile, up from five mentioned in the company's August 10 blog post. Users reportedly spend more than four hours daily in the software, a remarkable engagement metric for enterprise tools.
Named clients include Mercator Partners and California-based Verso Partners. Scott Hobart, Mercator's chief investment officer, offered a vivid description of the shift: "We used to spend 80% of our time gathering information and 20% acting on it. Multiplier has flipped those percentages."
Michael Siliciano, co-founder of Verso Partners, described a familiar pain point among smaller funds trying to build proprietary AI capabilities. Maintaining internal AI tools "became a full-time job," he said in a testimonial. "That's why we brought on Multiplier."
Taking Aim at a $30,000-Per-Seat Giant
The company says its ambition is nothing less than replacing Bloomberg Terminal for equity research, starting with the user interface before moving to backend data. Multiplier claims it will save clients $30,000 per seat annually, a figure aligned with published estimates of Bloomberg's single-seat pricing from third-party data aggregators.
Rather than building a walled garden, Multiplier integrates with dozens of existing financial data providers. Logos on the company website include MSCI, FactSet, Refinitiv, Bloomberg Terminal itself, Aladdin, Enfusion, Tegus, AlphaSense and Third Bridge.
Whether hedge funds will actually abandon Bloomberg remains an open question. The Terminal has survived countless would-be disruptors over four decades, in part because it doubles as the industry's communication backbone. Multiplier appears to be betting that AI-native tools can finally change the calculus for at least some segment of users.
A Form D filed with the SEC on July 6 showed the company had sold roughly $3.98 million to 57 investors as of that date, with the first sale on March 17. The gap between that figure and the $6 million announced in August suggests additional closings came together quickly through the summer.
"This money will buy us the talent and tokens we need to make Multiplier the obvious choice for any AI-pilled investor," the founders wrote in their August blog post, using industry shorthand for computation credits needed to run large language models.
Multiplier is relocating from San Francisco to Midtown East in Manhattan and hiring software engineers, according to its careers page. The move puts the startup within walking distance of many of its target customers. Sometimes geography still matters, even in the age of remote work.
