Heidi sells clinical software that records a medical visit, drafts structured notes and leaves the clinician to review the result before it enters the health record. The company says it has secured $340 million: a $100 million Series C led by Blackbird and a separate $240 million growth investment led by General Catalyst’s Customer Value Fund.
During a typical consultation, Heidi captures the conversation and turns it into a note for the clinician to check. The same system can draft referral letters, patient summaries and other documents; paid practice plans add full electronic-health-record integrations and shared templates. The product connects the visit with the administrative work that follows.
The company has also pushed beyond its original scribe. Evidence lets clinicians ask medical questions and open citations to underlying guidelines and research. Remote is a wearable microphone designed to capture rounds away from a desk, while Comms handles patient calls, bookings, reminders and follow-ups.
Heidi uses a freemium subscription model. Its free plan includes unlimited transcription, note generation from standard templates and citation-backed Evidence queries. Paid Clinician and Practice tiers add advanced templates, more in-session assistance, team controls and electronic-record integrations; enterprise pricing is negotiated separately.
Those offerings address individual clinicians and larger provider organizations. Heidi’s homepage displays Beth Israel Lahey Health and carries a testimonial from MaineGeneral Health’s chief information officer; an earlier company announcement also described collaborations or pilots with Monash Health and NHS trusts.
Heidi’s previous round, announced in October 2025, was a $65 million Series B. The new package is more than five times larger, but only $100 million is labeled as the Series C. The remaining $240 million sits in the separate growth investment, so the headline total combines two financing channels.
