Pursuit | Full‑Stack & AI Engineers | Ann Arbor (MI) / Los Angeles (CA) / Remote (US‑only) | Full‑Time

Look at the latest government‑tech headlines and you’ll find our customers. Pursuit (https://pursuit.us) is using AI to fix one of America’s costliest, most overlooked problems: the painful process of selling to 109 000+ state and local agencies. We turn budget PDFs, board‑meeting transcripts, and financial reports into structured insight so the best vendors—not just the best‑connected—win.

About Pursuit Founded after our previous founder's company exited for $200 M; 15 months in with clear product‑market fit.

Trusted by: OpenGov, Flock Safety, Wiz, Granicus, Qualtrics, NeoGov and 50+ other top GovTech/SLED vendors.

Backed by: Jack Altman, Blake Robbins, Bill Gurley, Sam Hinkie, AI Grant, and angels behind OpenAI, Rippling, Airtable, Anduril.

Why We’re Different: Deep signal – we mine every public document others ignore. Compounding data loop – more FOIA data → better models → faster wins. System‑level rethink – we’re not optimizing the old process; we’re rebuilding it. Real traction – Pursuit is the default tool for vendors tired of surprise RFPs and incumbent lock‑in.

What We’re Looking For:

* Engineers who want to die knowing they made the country better.

* People who enjoy weird, high‑scale data problems.

* Builders willing to chip away at a system everyone else gave up on.
