Seamflow

Seamflow is building the software layer for the testing, inspection and certification (TIC) industry — the invisible infrastructure that keeps the physical economy safe. Every plane, medical device, lift, battery and building has to be tested, inspected and certified before it reaches the world, and that entire process still runs on Word documents, PDFs, spreadsheets and email.

Seamflow builds AI-powered workflows for certification bodies, notified bodies and inspection companies, covering scheduling and resource planning, technical review, conformity assessment, field inspection, and document intelligence over messy real-world files.

Founded in 2025 and backed by a $4.5M seed round (14x oversubscribed), co-led by Northzone and Initialized Capital — the funds behind Spotify, Klarna, Coinbase and Reddit — Seamflow has gone from one customer a year ago to being deployed inside six of the ten largest enterprises in the industry. The company's valuation has quadrupled this year, and investors have already offered to lead a Series A.

Seamflow runs one of the most ambitious startup cultures in Europe: fast-paced, extremely high ownership, and in-person from their Shoreditch, London office. The team hires against a very high bar — engineering excellence is the number one priority — and the culture is defined by speed, taste, and a relentless focus on building systems that hold up in the real world.
