Senior or Staff Full Stack Engineer

About Finch

Insurance claims are still run out of shared inboxes, PDFs, and tribal knowledge. Billions of dollars move through workflows that were never designed to scale, and everyone pays for that friction.

Finch is the intelligence layer that fixes this.

We sit on top of email and existing claim systems and turn unstructured claim activity into structured, real-time data. Every message, document, photo, and instruction becomes part of a living claim graph that understands coverage, damages, financials, parties, and deadlines.

Finch doesn’t replace core systems or force process change. It overlays how adjusters already work and automates what slows them down: follow-ups, document validation, summaries, SLA tracking, and next-best actions. In production, we automate up to 90% of operational claim work.

The result: faster cycle times, cleaner audits, and full visibility across every claim—without adding headcount.

We’re not building a better inbox or another claims tool.
Finch is becoming the system of agreement for insurance claims—the infrastructure layer where claim state is normalized, decisions are driven by data, and settlement friction disappears.
