Why We Invest in the Developer Layer

Every major technology wave is built on a foundation of developer tooling. We identify and back the companies building those foundations before the wave arrives.

Developer-Led Growth

The most durable enterprise software companies start by earning the trust of individual developers. We invest early in that trust-building process, backing tools that developers choose for themselves.

API-First Architecture

APIs are the building blocks of modern software. We back infrastructure and platform companies that expose their value through well-designed programmatic interfaces that compound over time.

Open Source Commercial Paths

Open source projects capture mindshare that closed-source products cannot. We partner with founders who understand how to build sustainable commercial businesses on open foundations.

CLI and Automation Tools

Command-line interfaces remain the most powerful productivity surface for developers. We back companies building automation tooling that saves engineers hours every week.

Data Infrastructure

As data volumes explode, the tooling for storing, moving, transforming, and querying data becomes increasingly valuable. We look for teams with deep technical credibility in this space.

AI-Assisted Development

AI is fundamentally changing how software is written, reviewed, tested, and deployed. We invest in the tools that keep human engineers in control of that transformation.
