What Aaron.ai does

Aaron.ai, founded in Berlin in 2015, developed an AI-powered telephone assistant that handles inbound patient calls for medical practices, extracts structured information, books appointments directly into Doctolib's practice management platform, and sends SMS notifications for items such as sick notes (Arbeitsunfähigkeitsbescheinigung). The system combines speech recognition, natural language processing, and generative AI for outbound SMS and call summaries, and is operated via a multi-device webapp. Aaron was launched as a commercial product in 2018 and serves 16,000 doctors, therapists, and healthcare workers across Germany, processing roughly 3 million calls per month. The product is designed specifically for German healthcare workflows and was developed with input from doctors and medical assistants (MFAs).
