The people management platform driving engagement, performance, and growth
HQ: San Francisco, CA, United States (HR-remote) | Founded: 2015 | Employees: ~700-900 (2025, est.) | Stage: Series F (~$3B, 2022); private (2025 data-center+AI expansion) | Website: https://lattice.com
Lattice was founded in 2015 by Jack Altman (brother of OpenAI's Sam Altman) and Eric Koslow, who met while working together at Teespring (they both left; Koslow had a data-science background and Altman a product background). The pair launched through Y Combinator's W16 batch to fix broken, infrequent performance reviews — the thesis being that employees deserve continuous, meaningful performance and growth conversations, not annual rituals.\n\nThe platform grew into a full people-management suite: Performance (reviews, check-ins, 360s), Engagement (pulse surveys and analytics), Goals/OKRs, and later Compensation and Career/Growth modules — plus native AI features (Lattice AI for drafting reviews, creating goals, summarizing survey data). It's used by over 4,000+ companies across industries, with a customer list spanning Reddit, Shopify, Duolingo, Netflix, IBM, Pinterest, and Webflow, and supports 3,300+ people managers.\n\nFinancially, Lattice reached a reported ~$100M ARR (~2021-22) and raised a $150M Series F at a ~$3B valuation in early 2022 (preceding the tech downturn). Since then it has expanded internationally and deepened AI — with 'Lattice AI' and data-center/perception work, aiming to become the AI-driven people platform. It remains privately held. Founders are NOT ex-Plaid — they met at Teespring (YC W16) — and the company is one of the strongest modern-HR challengers to Workday and dedicated performance tools.
Lattice has become the default modern people-management platform, riding the shift from traditional, annualized HR software (Workday, 15Five, Betterworks) toward continuous, engagement-centric, AI-augmented performance management. Founded in 2015 by Jack Altman and Eric Koslow (met at Teespring, YC W16) — who later married org and product — Lattice gained a blue-chip customer base (Reddit, Shopify, Duolingo, Netflix, IBM, Pinterest, Webflow) and a ~$3B valuation via a $150M Series F in early 2022. The bull case: sticky, multi-module platform (performance, engagement, OKRs, compensation, and now AI) that expands enterprise value; the bear case: intense competition (Workday, Betterworks, Culture Amp, 15Five, Leapsome) and the need to keep innovating on AI. Lattice's breadth, brand, and scale keep it near the top of the people-tech category.
