Stellar

Stellar is a no-code AI voice agent platform that automates inbound and outbound phone calls for small to medium-sized businesses, especially in home services, healthcare, and professional services. It answers calls autonomously, qualifies leads, books appointments, confirms events, and handles routine customer support—freeing up staff to focus on higher-value work. With a 10-minute setup and no coding required, users configure agents via an intuitive builder, connect their calendar and CRM, and launch immediately. Stellar includes preloaded industry knowledge for 16 verticals (e.g., HVAC, plumbing, dental, real estate), self-learning agents that improve after every call, and compliance features (TCPA, FCC consent, AI disclosure). The platform supports four core conversation types: lead qualification, appointment booking (including reschedule/cancel/lookup), event confirmation with multi-touch reminder sequences, and customer support via a knowledge base. Key features include speed-to-lead analytics, call quality scoring, replay regression testing, CRM enrichment (greeting inbound callers by name), multi-agent pipelines for complex workflows, and a voice widget for website embedding. Integrations span Google Calendar, Calendly, HubSpot, ServiceTitan, Housecall Pro, Slack, and more. Pricing is per-minute with overage, scaled across five paid tiers starting at $149/month. Compared to alternatives like Smith.ai or Goodcall, Stellar offers deeper vertical specialization and more automation features, but its overage costs can add up for high-volume users.
