Thomas Dohmke secured $60 million in seed financing for his new startup Entire, valuing the developer tools company at $300 million. The former GitHub CEO left Microsoft's code hosting platform in August 2025 to build infrastructure for AI-generated software.
Felicis Ventures led the investment round, describing it as the largest seed commitment to a developer tools company. Madrona Venture Group, Microsoft's M12 fund, and Basis Set Ventures participated alongside angel backers including Yahoo co-founder Jerry Yang.
Entire released Checkpoints as its initial open-source offering, a command-line interface that captures context from AI coding assistants. The tool works with Anthropic's Claude Code and Google's Gemini CLI initially, storing prompts, transcripts, and execution traces alongside code changes.
"Massive volumes of code now emerge faster than human teams can comprehend them," Dohmke stated.
He argued that traditional software development workflows, built around issues, Git repositories, pull requests, and deployments, were never architected for artificial intelligence workloads.
The startup plans a three-component technical foundation. A Git-compatible database will unify AI-produced code, while a semantic reasoning layer aims to coordinate multiple AI agents. An AI-native user interface completes the architecture, designed specifically for agent-to-human collaboration.
Dohmke served as GitHub's chief executive from 2021 through August 2025, overseeing the expansion of GitHub Copilot. Under his leadership, the AI coding assistant reached 80% adoption among new platform users within their first week, according to October 2025 metrics.
Entire currently operates with 15 remote employees and intends to expand engineering headcount beyond 30 in coming months. The company follows an open-source business model, with Checkpoints establishing the foundation for broader platform capabilities.
Dohmke previously founded HockeyApp, a mobile crash reporting platform Microsoft acquired in 2015. That acquisition brought him into Microsoft's developer tools organization before his appointment to lead GitHub six years later.
The funding announcement arrives as AI-assisted coding transitions from experimental feature to standard practice. GitHub reported 180 million developers on its platform last October, with four-fifths of newcomers immediately adopting Copilot tools.
Checkpoints addresses what Dohmke calls "the review bottleneck." AI coding agents can generate software modifications faster than engineering teams can audit them, creating security and quality control challenges across the industry. Similar security concerns have emerged in other AI platforms as adoption accelerates.
Entire's approach treats AI agent outputs as durable engineering artifacts rather than temporary chat conversations. By preserving the reasoning behind code changes, developers can trace decision pathways and understand why specific implementations were proposed.
The platform aims to function alongside existing tools rather than replace them. Code repositories will remain central to software development, but Entire adds transparency layers specifically designed for AI-generated contributions.
Early adoption will depend on integration simplicity and demonstrable productivity gains. Developers need clear workflow benefits to incorporate additional tooling into their existing environments, especially when managing multiple AI assistants simultaneously.
Dohmke's venture represents a significant bet on AI's permanent role in software creation. As coding assistants become default components of development workflows, infrastructure must evolve to support auditability, reproducibility, and team coordination at scale.
The $60 million financing establishes Entire as one of the best-funded developer tools startups at seed stage. Its success will hinge on whether engineering organizations prioritize transparency and governance for AI-generated code as essential rather than optional.
