Work-Bench Research Document
Executive Summary
Work-Bench is a New York-based seed-stage venture capital firm focused exclusively on early-stage enterprise software investments. Founded in 2012 by Jonathan Lehr and Jessica Lin, the firm has established itself as NYC's go-to seed investor for founders building the next generation of enterprise, SaaS, and infrastructure software. With the announcement of Fund IV ($160M) in May 2025, Work-Bench has doubled its capital from Fund III and continues to be a prominent force in early-stage enterprise tech investing.
Investment Thesis
Work-Bench operates with a clear, conviction-driven thesis focused on enterprise software at the seed stage. The firm believes that go-to-market (GTM) is the core moat for early-stage enterprise companies, and they position themselves as hands-on GTM specialists who work alongside founders from day one. Their philosophy centers on backing "gritty, early, conviction-driven founders" with deep domain expertise who see problems differently than the crowd.
The firm explicitly avoids chasing hype cycles or FOMO rounds. Instead, their investments are grounded in thematic research and hundreds of conversations with enterprise buyers. They form their own opinions about market trends rather than following the crowd, making concentrated bets where they have genuine conviction.
Stage and Check Size Focus
Work-Bench is exclusively a seed-stage investor with a highly focused check size range:
- Primary Check Size: $2M - $4M
- Fund Status: Fund IV ($160M) actively deploying
- Strategy: Lead seed rounds with strong conviction
- Check Range History: Previously $3M - $6M (from existing firm data), now refined to $2M - $4M with Fund IV
The firm takes a concentrated portfolio approach, meaning each investment receives meaningful capital and ongoing support rather than participating in numerous deals at small check sizes.
