About

What is Regal

Regal lets teams build and deploy AI voice agents that conduct outbound calls, send SMS, and handle multi-step customer workflows without a human on every interaction. It's built for SDR and BDR teams, RevOps, and GTM leads at growth-stage through enterprise companies who need to run high-volume outreach across voice and text from a single platform. The standout capability is event-driven journey orchestration — Regal connects to first-party customer data and triggers personalized call and SMS sequences based on real customer behavior, not just static lists. It integrates natively with HubSpot CRM, Slack, Zapier, Segment, Klaviyo, and Braze, with case studies spanning insurance, healthcare, lending, and education. The honest limitation: Regal is purpose-built for voice-first outreach, so teams looking for a broad sales engagement suite with deep email sequencing will find the email channel thin compared to dedicated outbound email tools.

Our verdict

Vanderbuild take

Regal sits at the intersection of phone dialer and multichannel outreach, and it's one of the few tools in this category where the AI agent layer is the product — not a bolt-on feature — which makes it worth serious attention for RevOps and GTM leads running high-touch outbound at scale. On the agentic readiness front, the REST API is available and documented, so you can wrap Regal into your own orchestration layer or MCP setup without too much friction, though MCP-native status is unconfirmed. Pricing is not publicly listed, which means you're going into a sales conversation blind — budget accordingly and expect contract-level discussions rather than self-serve signup. The honest limitation is channel depth: Regal is voice-first, and if your outbound motion depends heavily on email sequencing, you'll need a separate tool to cover that leg of the workflow.
