About Repository Radar

// the repository radar manifesto

Pieter Bruegel's Tower of Babel
Like the Tower of Babel, the open-source community builds upward, one layer at a time, creating the software stack that powers nearly every digital experience.

We believe the most important software of the next decade is being written in the open, in public, by people who will never send you a pitch deck.

The signal is out there. It's just buried. Every day, thousands of commits, releases, and quiet first-version repos ship into a firehose nobody has time to drink from. The interesting stuff, the primitive that becomes infrastructure, the sleeper library that ends up under everything, rarely announces itself. It gets a star here, a Hacker News comment there, and then one day it's load-bearing.

We read the firehose so you don't have to.

Repository Radar is a bet that open source is the leading indicator. Not the press release, not the funding round, not the keynote. The code. What developers actually adopt, fork, and build on tells you where the industry is going months before the narrative catches up. We'd rather show you the repo than the roadmap.

We have a few commitments.

We follow the work, not the hype. If a project matters, we'll say why in plain terms, and if it doesn't, we won't waste your inbox on it. Attention is the scarce resource, and we treat yours with respect.

We stay close to the ground. Infrastructure, tooling, models, the unglamorous plumbing of AI and software. This is where leverage compounds and where most of the value quietly accrues. We are not here to chase whatever is trending on the timeline this week.

We show our reasoning. You should be able to disagree with us. We'll tell you what caught our eye and why, and you can go look yourself. The source is right there, which is rather the point of the whole thing.

We give credit to the builders. Behind every repo is a person, often unpaid, usually unthanked, who decided the world needed a thing and then made it. We name them where we can. The maintainer graph is the map that matters.

We keep it human. Two people, a shared curiosity, a bi-weekly cadence, and no illusions that we've caught everything. We'd rather be honest and occasionally wrong than comprehensive and lifeless.

The radar sweeps every two weeks. Some blips are noise. A few are the start of something. Our job is to keep watching, and to tell you what we see.

Welcome aboard.

Co-writes Repository Radar. Partner at Keen Venture Partners in Amsterdam, backing AI-native software for Europe's SMEs. Fifteen-odd years across finance, tech and consulting before that: Gen AI and frontier-tech investing at Picus Capital, product and international growth at JD.com in Beijing, earlier stints at McKinsey and IBM, and a Schwarzman Scholarship somewhere in the middle. Occasionally builds the thing instead of funding it.

Co-writes Repository Radar. MIT, CDTM and TUM; now at Index Labs, building proprietary agentic-AI platforms and custom automation for forward-thinking organizations, after investing alongside Alexander at Picus Capital. Reads more diffs than is strictly advisable, which turns out to be roughly the qualification the job requires.
