About Stellar
Stellar is an AI platform that deploys autonomous, no-code voice agents capable of holding natural, human-like phone conversations. These agents autonomously qualify leads, book appointments, and confirm events without manual intervention. The system self-learns from every call, automatically applying high-confidence improvements to optimize future interactions. Voice agents can be chained into multi-agent pipelines to handle complex workflows. Stellar integrates with popular business tools such as Google Calendar, HubSpot, Salesforce, and Zapier to streamline operations. Businesses use Stellar to reduce lead response times, minimize no-shows, and scale 24/7 calling without hiring additional staff. The platform prioritizes security with enterprise-grade encryption and compliance controls, including TCPA, GDPR, and SOC 2 readiness, ensuring data protection across all interactions.
