Summary
Bunkerhill Health raised a $25M Series B led by Khosla Ventures, bringing total funding to $55M, for Carebricks — a platform that lets health systems build and own their own clinical AI agents rather than depending on fixed vendor tools. The platform is already live at 15 health systems including Cleveland Clinic, Mayo Clinic, and Intermountain, with reported outcomes including a nephrology triage agent cutting specialist wait times by over 50% and a lung nodule agent addressing urgent cases 80% faster.
Key Takeaways
- The pitch is explicitly build-your-own rather than buy-a-fixed-product: Carebricks gives hospitals the platform to construct clinical agents tailored to their own workflows instead of adapting their workflows to a vendor's fixed tool.
- Already deployed at 15 health systems, including three of the most recognizable names in US healthcare (Cleveland Clinic, Mayo Clinic, Intermountain) — meaningful adoption breadth for a platform still at Series B.
- Reported clinical impact numbers are specific to workflow stages, not vague: a nephrology triage agent cutting specialist wait times over 50%, and a lung nodule agent getting urgent cases addressed 80% faster.
- A named clinical anecdote — a coronary calcium agent flagging a patient for emergency bypass surgery — grounds the pitch in an actual patient-outcome story rather than only aggregate metrics.
Reel Script
Hook (16s / 36 words) A hospital-AI startup just raised $55 million with a pitch that inverts the usual model: instead of selling hospitals a fixed AI tool, they're selling hospitals the platform to build their own.
Core Concept (55s / 120 words) Most clinical AI products are delivered as a finished tool — a specific model trained for a specific task, take it or leave it. Bunkerhill's Carebricks platform does something different: it gives health systems the building blocks to construct their own clinical agents around their own specific workflows and specialties, rather than forcing every hospital into the same fixed product. That matters because hospital workflows genuinely differ — how Cleveland Clinic triages nephrology cases isn't identical to how a smaller regional system does it — and a build-your-own platform can flex to that in a way a one-size-fits-all vendor tool structurally can't.
Hands-On (55s / 120 words) The concrete numbers: $25M Series B led by Khosla Ventures, $55M total raised, already deployed at 15 health systems including Cleveland Clinic, Mayo Clinic, and Intermountain. Two specific clinical-agent results stand out — a nephrology triage agent that cut specialist wait times by more than 50%, and a lung nodule agent that got urgent cases addressed 80% faster than before. There's also a named patient-level anecdote: a coronary calcium screening agent flagged a patient as needing emergency bypass surgery, which is the kind of single concrete outcome that's harder to dismiss as aggregate-statistics spin.
Takeaway (22s / 48 words) The real signal here isn't the funding round, it's the adoption depth — 15 health systems including three top-tier names is a genuine production footprint, not a pilot. Worth watching whether "build your own clinical agent" outcompetes fixed vendor tools at scale.
