Stamina.io – AI-Powered Outbound Sales for SMBs

Company profile:

Startup name: Stamina.io

Tagline: Outbound that books itself

Elevator Pitch: 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.

The platform covers power dialling with auto-logging and disposition tracking, multi-step email and SMS campaigns with deliverability tooling built in, contact and account management without the bloat, trigger-based workflow automation across channels and pipeline stages, and an AI agent hub for reply handling, lead enrichment, and signal-based prioritization. Sending infrastructure is also managed natively, with provisioned inboxes, domain management, and warmup monitoring included. Stamina.io is purpose-built for revenue teams that run lean but need enterprise-grade outbound infrastructure, without the sprawl of cobbling together Apollo, Clay, Salesloft, and Instantly separately.

Target Market: SMBs, sales teams, B2B companies, agencies, and revenue teams looking to automate outbound sales and customer engagement.
