JawBuddy raises €818,000 for app that treats jaw pain
What's the deal? JawBuddy, a German medtech startup, has raised €818,000 (about $919,000) in a round led by healthcare platform HALBZEIT. The company builds a digital self-therapy app for people with craniomandibular dysfunction (CMD) and bruxism, or teeth grinding.
How it works: The app delivers personalised exercise programs and uses the smartphone camera to track therapy progress. It is designed to complement dental treatment and bridge the gap between office visits, rather than replace them.
Who's backing it? Alongside HALBZEIT, investors include dentist Dr. Siegfried Marquardt, oral and maxillofacial surgeon Dr. Guido Sigron, Mittelständische Beteiligungsgesellschaft Sachsen, and business angels Christophe Barriolade, Aldrich Huang, Jens Kosche, and Marc Scheidegger. The total also includes a business angel bonus from the Sächsische Aufbaubank.
Why it matters: Chronic jaw pain affects many people, and treatment often leaves patients on their own between dental appointments. "I myself had jaw pain for years and experienced firsthand how little you can do between two dental appointments," said co-founder and chief executive officer Leon Rauch.
The investor view: HALBZEIT is betting on a mix of clinical need and a path to reimbursement. "We invest where a large, underserved market, a clear clinical need, and a reimbursable model converge," said Luisa Wasilewski, pool captain at HALBZEIT.
What's next? The startup, founded in 2024 and headquartered in Stuttgart, aims to establish the app as a certified digital health application in Germany. It was previously marketed as KauSchlauDealroom has a profile for this one. Try Dealroom → before rebranding to JawBuddy in November 2025.
The signal: The round reflects growing appetite for digital therapeutics that extend specialist care into the home. It also shows how tokenised securities are opening private medtech deals to healthcare-sector investors — HALBZEIT structured the issuance as a compliant electronic security under Germany's eWpG framework.
