Who We Are:
We build infrastructure that delivers massive amounts of web data to the companies training the world's most powerful AI models.
We're the team that helps to power and support Grass, a bandwidth-sharing network that lets us operate a massive distributed crawler, giving us unique access to high-quality public web data at global scale. On top of that, we've built pipelines for ingesting, segmenting, and annotating billions of videos, transcripts, and audio files, powering dataset creation for frontier labs.
We're lean, technical, and move fast. No red tape, no slow decision-making; just a team of builders pushing to expand what's possible for open web data and AI.
