Benchmark hires Jack Altman, founder of Alt Capital and Lattice, as its fifth general partner.
Benchmark hired Jack Altman as its fifth general partner in February 2026, marking the elite venture capital firm's first GP addition in years. Altman — founder of Alt Capital and HR software company Lattice, and Sam Altman's brother — brings three Alt Capital team members with him. Benchmark's equal-partnership model is legendary in venture capital: every partner gets the same economics, the same carry, and the same vote. The firm has backed some of the most successful companies in tech history, including eBay, Twitter, Uber, Snapchat, and Discord. Adding a fifth partner to this structure means Benchmark sees enough opportunity — and enough conviction in Altman specifically — to dilute every existing partner's share. Altman's dual credibility as both a founder (Lattice scaled to hundreds of millions in ARR) and an investor (Alt Capital's early-stage portfolio) is exactly what top VC firms look for. For founders raising from Benchmark, Altman adds a partner who has sat in their seat — building product, closing enterprise deals, and navigating the founder journey from zero to scale.
