HealthKey —

We stumbled across HealthKey in Y Combinator's Winter 2025 batch, and honestly, their approach caught us off guard. Most healthcare AI startups go after the obvious stuff like diagnostics or patient engagement. HealthKey? They're tackling one of the most tedious bottlenecks in medical research: finding the right patients for clinical trials.

The company's main pitch is simple but clever. Instead of research coordinators spending hours manually combing through electronic health records to find trial-eligible patients, HealthKey's AI does the heavy lifting. You plug in your inclusion and exclusion criteria, connect to the EHR system, and get back a list of potential matches with evidence to back up each recommendation.

What Makes This Interesting

Here's where HealthKey gets smart about positioning. They're not just building another "AI for healthcare" tool. They're solving a very specific workflow problem that costs research sites real time and money. Clinical trial recruitment is notoriously slow and expensive, so anything that speeds up patient identification has immediate value.

The technical approach seems solid too. Rather than just keyword matching or basic filters, their system apparently understands medical terminology and can cross-reference complex eligibility requirements against patient histories. That's the kind of AI application that actually makes sense in healthcare.

Beyond Trial Recruitment

What's fascinating is how HealthKey seems to be expanding beyond their core clinical trial focus. They've got a chart prep tool for general healthcare providers and something called "HealthKey Chat" for HIPAA-compliant medical summarization. It feels like they're using their core AI engine to tackle multiple healthcare workflow problems.

This diversification strategy is smart. Clinical trials are a great entry point because the pain is so acute, but the broader market for healthcare AI tools is obviously much larger. They're building trust in a narrow use case, then expanding outward.

Early Stage Reality Check

Let's be honest: HealthKey is still very early. Founded in 2025 and just coming out of YC, they're essentially a seed-stage startup with big ambitions. The reported £1.13 million funding round suggests they've got some runway, but they're competing in a space where established players have deep pockets and existing relationships.

That said, being in YC gives them credibility, and founder Josh Sabol seems focused on solving real problems rather than chasing buzzwords. In healthcare AI, that practical approach often wins over flashier competitors who promise the moon but can't deliver basic workflow improvements.
