Stamina.io

Stamina.io is an all-in-one outbound sales platform designed for SMBs and mid-market companies running high-volume outbound motions. It combines a power dialler, built-in CRM, multi-channel sequencing across email, SMS, and calls, workflow automation, and an AI agent hub, giving sales teams everything they need to prospect, engage, and close from a single platform. Unlike stitched-together stacks, Stamina.io is built natively end-to-end. Sequences trigger calls, calls feed the CRM, and AI agents handle reply classification and follow-ups automatically. The Reply Agent reads inbound emails, classifies intent across interested, not interested, out of office, and wrong person signals, then routes or responds accordingly so reps spend time selling instead of sorting inboxes.
