Founding Story
Jack Altman co-founded Lattice in 2015. After working in venture capital and early-stage startups, he realized that modern tech companies lacked proper software to manage employee performance and goal-setting (OKRs). As CEO, he successfully built Lattice into the absolute default HR performance platform for Silicon Valley before stepping down in 2024 to launch a new venture fund.
Altman led Lattice as chief executive until 2023. He is now a general partner at the venture capital firm Benchmark, and earlier founded Alt Capital and, with his brother Sam, Hydrazine Capital. Jack Altman was born in 1989.
