The platform integrates with CRMs, calendar tools, and databases via native integrations and APIs. - **Proprietary Calendar**: An AI-native calendar tool that is already live as part of the platform. - **Proprietary CRM**: A CRM purpose-built for AI-driven customer interactions, expected to launch by the end of Q3 2026. ## Market Standing - **Valuation/Market Cap**: $140 million valuation (as of June 2026, per seed round) - **Key Metric**: Total funding of over $20 million, including a $17 million seed round led by 20VC (June 2026) and a €3 million angel round (December 2025). - **Notable Investors/Partners**: 20VC (lead), with participation from founders and executives of Synthesia, HubSpot, and Revolut.
