Stamina.io
Outbound in one place
What is Stamina.io
Stamina.io pulls CRM, email, SMS, power dialer, and AI prospecting into one workspace so SDRs, BDRs, and GTM engineers don't have to stitch together separate tools for each channel. It's built for B2B sales teams ranging from SMBs and agencies to mid-market and enterprise orgs running high-volume outbound. The standout capability is Zara, an AI BDR that automates lead targeting, message personalization, and sequencing end-to-end — not just drafting copy, but running the sequence autonomously. Agencies get a white-label option to run client campaigns under their own brand. The platform has no publicly documented API, so teams that want to plug Stamina into a broader automation stack or custom tooling will hit a wall quickly.

Vanderbuild take
Stamina is a consolidated outbound stack — CRM, dialer, email, SMS, and an autonomous AI BDR (Zara) — aimed squarely at SDR/BDR teams, GTM engineers, and agencies who want one bill instead of five. On the agentic readiness front, there's no API and no MCP server; this is a UI-only platform, which means you cannot drive it programmatically from an agent or orchestration layer without scraping — a real ceiling if you're building anything custom on top. At $599/month for the Base tier, budget for an experienced operator — vanilla setup leaves value on the table, especially given how much of the platform's leverage lives in configuring Zara and the signal-based triggers correctly. Native integrations are also absent from the public documentation, so if your team runs a tight HubSpot or Salesforce workflow, expect manual handoffs or CSV exports rather than a clean sync.
