What they do
We're a team of founders and operators turned investors who lead/co-lead investment rounds at the Seed and Series A. We stick to the categories we know best: software infrastructure, developer tools, data, security, and vertical SaaS. We’re fans of open-source software and excited by recent advances in AI.
