Jack Altman is a General Partner at Benchmark and the founder of Alt Capital, where he invests with an “operator-first” lens after serving until 2023 as CEO of the HR software company Lattice[3][5][11]. His investment thesis targets Seed and Series A startups in sectors including AI, Enterprise SaaS, Fintech, Health IT, and Digital Health, primarily in the United States[5][11]. Alt Capital recently raised $275 million for Alt Capital II to lead more Series A rounds, reflecting a shift toward taking lead positions rather than just following[12]. His typical check size averages around $8.8 million per round, with roughly 2.3 investments per year[4]. Notable portfolio companies include Lattice (his own company), Opendoor, Instacart, Pinterest, Gusto, Flexport, and PlanGrid[6][9]. Altman distinguishes himself by applying a “durability test,” evaluating whether products will remain in use 10+ years rather than chasing short-term trends, and he mentors founders on product, team building, and fundraising[5][11].
