Scarlet Raises $50M for AI Medical Certification

AI medical products can change much faster than conventional certification procedures. Scarlet has raised $50 million to build assessment infrastructure around that mismatch.

What happened

London-based Scarlet announced a $50 million Series B led by Headline, with participation from Notion Capital, Atomico, Creandum, Kindred Capital and Entrepreneurs First. Founded by former Babylon Health developers James Dewar and Jamie Cox, it operates as a designated certification and assessment organisation focused on software and AI medical devices. Its platform accepts product documentation and supports expert review under the relevant regulatory standards. Customers include digital-health companies developing AI scribes, diagnostic systems and other medical software. Scarlet's offering also supports ongoing surveillance, annual audits and changes to products after initial certification. Funding will support expansion in the US and Asia-Pacific and hiring of specialist reviewers and engineers.

Why it matters

A diagnostic model or clinical software product may be improved frequently, but the organisation behind it still needs to establish that changes meet safety and regulatory standards. Long delays can slow the delivery of improvements. Scarlet is trying to make the evaluation process more consistent and responsive without eliminating expert judgment or regulatory checks.

The bigger picture

As more healthtech businesses incorporate constantly updated AI models, certification may become an ongoing service rather than a one-off event. That creates room for specialised technology-enabled regulatory infrastructure. The challenge is showing regulators and patients that faster evaluation still produces reliable, evidence-based decisions.
