Engineer leaders investing in Infrastructure, Data Engineering, AI, DevOps, Security, Observability and Developer Productivity startups, at the pre-seed and seed stages

Irregular Expressions (IrregEx for short), backed by a group of seasoned software engineering and product leaders, invests in and advises early stage infrastructure, data,  and machine learning startups.

We’ve spent many cumulative decades bringing high-growth software products to market, and are focused on helping founders scale their own teams, products and businesses faster, leveraging both our know-how and our network.

Having co-founded, built and scaled hundreds of companies, primarily in the San Francisco and New York ecosystems, we love working closely with the founders and teams we back, and thinking together through thorny challenges on the product, engineering, and business fronts alike.
