About us Demodesk is the AI that does the job, not the AI that tells you what to do. For ten years, sales AI has handed dashboards to overwhelmed reps and called it transformation. We built something different: AI agents that join every sales conversation, update the CRM, send the follow-ups, coach reps after every call, and flag deals at risk before they slip. Founded in Munich in 2018 and backed by $15M from Balderton, Y Combinator, and the founders of HubSpot and Pipedrive, we serve 300+ customers and 20,000+ sales professionals across Europe, including Porsche, Bosch, Treatwell, OMR, and Enpal. GDPR-native, ISO 27001 certified, EU-only data. We are still small enough that everyone's fingerprints are on the product.
