What we're learning building Sellarion

We evaluated 6 AI SDR platforms on the criteria that actually matter — reply handling, personalization depth, CRM integration, meeting booking, and pricing transparency. One tool handles the full loop autonomously. Here's the breakdown.

A fully-loaded SDR costs $108K–$150K/year before they book a single meeting. An AI SDR costs $1,788–$8,388. We break down every cost component, the break-even timeline, and when human SDRs are still worth it.

Manual scheduling kills deal velocity. 47% of warm leads are lost to calendar back-and-forth. Here's how AI appointment setting works — and what separates full automation from glorified scheduling links.

Automated email reply detection is table stakes. Autonomous response generation is the moat. Here's why 5 reply types need 5 different actions — and how Sellarion closes the loop in under 90 seconds.

Most prospect lists are built on job title + company size. That's why they convert at 1%. Here's how to layer firmographics, technographics, behavioral signals, and intent data to build a list that books meetings.

Most sales teams stitch together 5+ tools for outbound. Here's why that breaks at scale — and how a single autonomous agent replaces the entire stack, end-to-end.

Why 95% of AI SDR tools fail at reply handling. How autonomous reply classification + context-aware responses change the game. Technical architecture breakdown.

How we built a 5-stage autonomous sales loop — from prospect research to autonomous reply handling — in 22 days. The bottleneck isn't sending. It's listening. Here's what we learned.
