## Questions

### Who runs investment decisions at Preston-Werner Ventures?

Tom Preston-Werner, the firm's founder, leads investment decisions. His background as co-founder of GitHub and the creator of Gravatar and Jekyll gives him a practitioner's lens for evaluating early-stage developer-tool companies. The firm's website positions PWV as an extension of his own founder experience, and no separate investment committee or dedicated GPs are publicly named.

### How does Preston-Werner Ventures source deals?

PWV's founder-first branding and Tom Preston-Werner's deep roots in the open-source developer community — as co-founder of GitHub, creator of the Jekyll static site generator, and an early participant in the Y Combinator network — point to a deal flow engine driven by personal network and technical credibility. The portfolio companies (Cursor, Supabase, Netlify) cluster in developer tools and infrastructure, reinforcing the pattern.

### How is Preston-Werner Ventures related to GitHub or Microsoft?

There is no corporate affiliation between Preston-Werner Ventures and GitHub or Microsoft. Tom Preston-Werner co-founded GitHub and left an executive role in 2014, well before the 2018 Microsoft acquisition. PWV is an independent entity that reflects his post-GitHub investment activity.
