AI SDR Software

AI SDR software · prospect → write → send → book, 24/7

# AI SDR software that does the whole job, for $29/mo

A human SDR costs $5,000+ a month and takes three months to ramp. FirstSales is AI SDR software that runs the entire sales-development motion on its own — it finds your buyers, writes and sends every email, follows up, and books meetings around the clock. It warms up and cleans as it sends, so 87% lands in the primary inbox.

* Replaces a $5k/mo SDR with software that starts at $29/mo
* Runs the full motion: prospect, write, send, follow up, book
* Works 24/7 across unlimited mailboxes with zero ramp time
* 87% primary-inbox placement, warm-up and cleaning built in
