Thesis
Heavybit, LLC is a venture capital firm founded in 2013 and based in San Francisco, California. They specialize in early-stage investments, focusing on developer-first and enterprise infrastructure startups. Their core thesis is to support founders with transformative visions who are innovating in how teams build, deploy, secure, and scale enterprise software. The firm targets companies creating category-defining enterprise infrastructure, including traditional software tools for engineering teams, AI, cloud-native infrastructure, open source, DevOps, and DevSecOps. Heavybit explicitly avoids investments in consumer internet, hardware, biotech, climate tech, and companies whose primary buyers are non-technical business functions. They primarily invest from Pre-Seed through Series A, with a strong emphasis on Pre-Seed and Seed rounds, often leading or co-leading these investments. The typical initial check size ranges from $500,000 to $5 million. In July 2025, Heavybit closed two new funds totaling over $180 million, bringing their AUM to a significant level. They allocate approximately 50% of their funds for follow-on investments.
