FAQ
AiSDR leans on a large proprietary contact database and HubSpot data. Alta connects to your CRM and 50+ sources and reads live buying signals across them, so outreach is triggered by intent — the right accounts at the right moment — and that same signal layer feeds every agent, not just outbound.
She is — for outbound. Leah is one AI SDR focused on the outbound motion. Alta’s three agents act autonomously on one shared brain across outbound, inbound, and revenue intelligence, so a signal from one motion immediately sharpens the next — and inbound leads get qualified and booked too, not just outbound.
AiSDR sells plans by monthly message volume — Explore (~1,200 messages at $900/mo) and Grow (~3,600 at $2,000/mo), billed quarterly with unlimited seats — and follow-ups in a sequence count toward that limit. Alta is an outcome-based system: cost scales with the pipeline you generate rather than message count.
No. Alta connects to your CRM and the data sources you already use, then takes over one motion at a time — usually outbound first. You can keep AiSDR running until Alta proves out each motion; most teams see first results in weeks and consolidate as they go.
Both are autonomous and AI-native — the difference is scope and architecture. AiSDR gives you Leah, a single AI SDR focused on outbound across email, LinkedIn, and SMS, built natively around HubSpot. Alta is one system of three agents — Katie, Alex, and Luna — that act across outbound, inbound, and revenue intelligence on a shared brain.
