Verifiable proof photos for work that happens on site.
ProStamp stamps every field photo with a trusted timestamp, GPS, and street address — sealed with a tamper-evident signature. Your office reviews, verifies, and delivers it all from one console.
Built for evidence, not decoration.
Every photo carries the proof a client, insurer, or auditor needs — captured the moment work happens, impossible to backdate or fake.
How it works
From the field to the client in three steps.
Capture
Open the app and shoot. ProStamp burns in the time, GPS, and street address, then seals the photo with a cryptographic signature.
Auto-upload
Photos sync to your team’s secure cloud the moment there’s signal — no manual export, nothing lost on a lost phone.
Review & deliver
Managers review by job, confirm authenticity, and export clean reports for clients and claims.
One system, two jobs
Made for the people in the field and the people in the office.
A camera that does the paperwork for you.
Crews just point and shoot. ProStamp handles the proof — even with no signal.

Each photo carries a tamper-evident signature. Drop one into our verifier to confirm the time, the place, and that not a single pixel has changed since capture.
