# Ex-GitHub Chief Leads $60M Seed at $300M Valuation
In a blockbuster move shaking up the venture capital landscape, Tom Preston-Werner, co-founder and former CEO of GitHub, is spearheading a massive $60 million seed round at a whopping $300 million valuation for an undisclosed AI-driven software startup. This investment underscores the surging demand for innovative tools in developer platforms and AI infrastructure, drawing on Preston-Werner's storied track record in scaling tech giants.[3]
Tom Preston-Werner's Journey from GitHub to Venture Powerhouse
Tom Preston-Werner transformed GitHub from a niche code collaboration tool into a global powerhouse, culminating in its $7.5 billion acquisition by Microsoft in 2018. As co-founder and former CEO, he pioneered technologies like Jekyll for static websites, Semantic Versioning (SemVer) for software releases, and TOML for configuration management, which remain industry standards today.[3]
Post-GitHub, Preston-Werner shifted to angel investing, backing over 175 startups including early bets on Stripe, Cursor, Netlify, Snyk, Supabase, PlanetScale, and Retool. His new venture, Preston-Werner Ventures (PWV), is raising a $100 million fund specifically targeting pre-seed and seed rounds in software- and AI-driven companies, positioning him as a go-to leader for high-valuation deals.[3]
This $60M seed leadership role at a $300M valuation highlights PWV's aggressive strategy to capture the next wave of tech innovation, building on Preston-Werner's deep expertise in developer tools.[3]
The Rising Influence of Ex-GitHub Leaders in AI Investments
Preston-Werner isn't alone among former GitHub executives making waves in funding rounds. Nat Friedman, GitHub's CEO from 2019 to 2021, has been actively investing through his firm NFDG alongside partner Daniel Gross. Friedman, who helped launch GitHub Copilot—one of the first generative AI coding assistants—led a $5.6 million seed for Composite, a browser-based web automation startup, in October of the previous year.[1][2]
NFDG's portfolio boasts heavyweights like Stripe, Character Technologies, Weights & Biases, and Perplexity AI, with investments ranging from $1 million to $100 million in seed and growth stages. Friedman and Gross, both AI veterans—Gross from Apple and Safe Superintelligence—are drawing Meta's interest for their expertise, amid reports of potential stakes in their firm.[2]
These moves reflect a trend where GitHub alumni are fueling the AI startup boom, leveraging their experience to spot and scale winners in coding, automation, and machine learning tools.[2][3]
Why This $60M Seed Signals a Hot Market for AI and Dev Tools
The $60 million seed at a $300 million valuation—led by Preston-Werner—signals robust investor confidence in early-stage AI and developer platforms, especially amid Microsoft's tighter integration of GitHub into its CoreAI team following CEO Thomas Dohmke's departure at the end of 2025.[4]
GitHub's evolution under Microsoft, from $7.5 billion acquisition to an estimated $16.5 billion valuation during Friedman's tenure, underscores the lucrative intersection of AI and software development.[2][4] Competition from players like Google's tools and startups such as Cursor is intensifying, making high-valuation seeds like this a bet on the next GitHub Copilot or infrastructure play.[2][4]
PWV's focus on "backing what's next" in software and AI positions this deal as a bellwether for 2026's funding environment, where ex-founders like Preston-Werner command premium influence.[3]
Broader Implications for Startups and Investors
This funding round amplifies PWV's $100M fundraise, attracting LPs eager for exposure to pre-seed and seed AI ventures. Preston-Werner's network, honed from GitHub's developer community, gives his portfolio companies an edge in talent and adoption.[3]
As Meta courts Friedman and Microsoft reshapes GitHub, the convergence of Big Tech and VC from industry veterans like Preston-Werner could accelerate AI tooling innovations, from code generation to web automation.[1][2][4]
