Heidi Health

Heidi is an ambient AI platform for clinicians that started as a medical scribe, sitting in on consultations to transcribe conversations and generate notes, referrals, and other documentation. The Melbourne-based company was founded in 2019 by Dr. Tom Kelly (CEO), Waleed Mussa (CFO), and Yu Liu (CTO) , and it is now used inside health systems including Beth Israel Lahey Health and MaineGeneral, alongside a recently launched hardware device called Remote that clips to a clinician and moves between rooms. This launch marks a $100 million Series C led by Blackbird at a $900 million valuation, paired with $240 million from General Catalyst's Customer Value Fund , with existing investors Phoenix Court, Point72 Private Investments, and Headline also participating . Blackbird was Heidi's first backer, writing a check in 2021 when Kelly pitched from a hospital cafe after a 24-hour shift with no product built. The capital arrives as Heidi expands well beyond documentation, with the company reporting roughly 2.8 million patient interactions supported each week . The direction Kelly is pointing at is a broader "AI care partner" that owns its own model layer rather than relying on frontier labs, running task-specific clinical models that can be deployed compliantly in every region and even on-device. Near-term ambitions include reasoning across long patient histories to work through complex cases, autonomously navigating legacy healthcare software so clinicians spend less time on administrative work, and opening a continuous patient-facing channel for care between visits. For founders and operators watching the crowded AI scribe category, this launch signals Heidi's move from single-feature scribe into a wider clinical agent stack.
