About Matt Hartman
Matt Hartman began his career building the technology platform for Trammell Crow Company, which CBRE later acquired. He then joined Hot Potato, which Facebook acquired, and built ReferBoost, a business licensed to Apartments.com. He studied cognitive science at the University of Pennsylvania and holds an MBA from Northwestern's Kellogg School.
Hartman spent nearly a decade at Betaworks, where he was a partner at Betaworks Ventures. His Factorial Capital bio says he was the first investor in Hugging Face, Anchor (acquired by Spotify) and Squad (acquired by Twitter).
He left in 2023 to start Factorial Capital, a New York-based early-stage firm. He is its founder and managing partner.
Most of Hartman's public record is institutional, through Betaworks and then Factorial. TechCrunch reported in 2025 that Factorial's sourcing partners can write checks individually, and often invest their own money alongside the firm. The coverage reviewed does not describe a separate personal angel portfolio, so this page does not list one.
Factorial describes itself as a venture firm built for the AI era. Its portfolio includes Hugging Face, Modal, Factory AI, Pika, Patronus, Nomic, Flower, Adaptive ML and Substrate.
In May 2026, Hartman took part in Ponder AI's $2.5M pre-seed round. Ponder AI is a New York company building an agentic video editor for professional filmmakers. Sunflower's Liu Jiang led the round, and Josh Browder also participated. The press coverage does not say whether Hartman invested personally or through Factorial. Crunchbase links the round to a different Matt Hartman profile, so founders should confirm his involvement directly.
Factorial says it invests in founders who code, building in infrastructure, B2B and consumer products at the frontier of what is newly technically possible. Hartman has said that successful early-stage AI investing needs real technical understanding, not pattern matching on traction or pedigree. He calls Factorial's early-stage focus "inception stage" on X.
The firm uses a network of technical venture partners who source deals. TechCrunch reported that Hartman was targeting about 30 investments from his first fund. The third-party directory VC Sheet lists an average check of $500K to $1M across pre-seed to Series A. Hartman has not confirmed that figure publicly. Techfundingnews reported a $25M Fund II.
