About Terac

Terac is the expert network powering frontier research. We make human labor accessible on-demand through a simple API. You tell us what job needs to be done and what kind of expert you need: we handle sourcing, screening, verification, and payouts.

We've raised $9M from Emergence, SignalFire, Audacious, and Z Fellows. We believe that as AI agents start running companies, the bottleneck won't be code, it'll be access to the right human at the right time.

We're hiring in-person engineers in San Francisco. If you build something great this weekend, we want to talk.

Our Berkeley Hackathon Challenge

This track is about making that model measurably better with data you collect yourself. The loop:

1. Build the annotation environment. A simple app (a Vercel app works great) where an AI generates tasks or outputs and a human labels, rates, or compares them.
2. We bring the annotators. Launch your task on Terac and we'll get real people to annotate it. You focus on the environment, not on recruiting or incentives. That part is on us.
3. Fine-tune and prove it. Train a model on the data you collected and show a clear improvement over the base model.

Pull that off within 24 hours and you've built something genuinely impressive.

Judging Criteria

Setup/Guidelines

• You'll sign in to Terac as a researcher. We'll give your team an org and credits.
• Each team gets $250 in Terac credit to spend on annotations.
• Annotators are general-population only. No specialist panels (no doctors, lawyers, and so on), which keeps turnaround fast and your credit going further.
