Founding Story

Jack Altman started Lattice in 2015 with Eric Koslow. He had worked at a fast-growing San Francisco startup where goals lived in scattered documents and performance reviews were disorganized and disliked. He saw that companies had good software for sales and engineering but not for managing people, and he left to build Lattice to fill that gap.

Jack Altman

Co-founder 2015

Background

Venture capitalist and startup operator.

Role at Lattice

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.

Eric Koslow

As the Chief Technology Officer, he was absolutely critical in designing the highly intuitive, modern interface that convinced employees to actually use the platform, completely displacing the universally hated, clunky legacy HR software used by older corporations. (Exact birth year remains publicly undisclosed).

Who Founded Lattice? FAQ

Who founded Lattice and what were their professional backgrounds?

Lattice was founded in 2015 by Jack Altman and Eric Koslow. Jack Altman (brother of OpenAI CEO Sam Altman) served as VP of Business Development at Teespring; Eric Koslow served as an early engineering lead at Teespring.

What was the original product concept when Lattice joined Y Combinator in 2016?

When Lattice entered the Y Combinator accelerator program (Winter 2016 batch), it initially built a goal-tracking and OKR management tool for tech companies, before expanding based on customer feedback into comprehensive 360 reviews and 1-on-1 management.

What motivated the founders to build a people management platform?

Having experienced the chaos of hyper-growth at Teespring, Altman and Koslow realized that as companies grow past 50 employees, organizational alignment breaks down, feedback loops disappear, and managers lack tools to develop their teams.

How did the founders bootstrap and validate early product demand?

The founders worked closely with dozens of early-stage Silicon Valley startup founders in 2016, personally onboarding teams, iterating weekly based on manager feedback, and building a product that employees actively enjoyed using rather than dreaded.

What role did Sam Altman and early angel investors play in Lattice's founding?

Sam Altman and prominent Silicon Valley angels (including Alexis Ohanian, Elad Gil, and Kevin Weil) provided early seed funding and strategic mentorship, introducing Lattice to its initial cohort of high-growth technology customers.
