    Startup Program

    Cartesia’s startup initiative gives founders free access to its voice AI platform to help them progress from prototype development to production deployment. Startups can build with Cartesia’s Sonic text-to-speech models, Ink speech-to-text technology, and Line voice-agent infrastructure, including voice cloning and real-time conversational capabilities. The official public page currently promotes free platform access but does not publicly disclose a standard credit amount, allocation period, or detailed eligibility requirements. Grant terms may therefore be determined individually after reviewing the startup’s application.
