Everyone in sales is suddenly saying it. Here's what an AI sales development rep actually does, the three kinds of AI SDR solutions on the market, what they cost — and where humans still win.

Definition
An AI SDR is software that does the work of a sales development rep — finding prospects, personalizing outreach, following up relentlessly, and booking qualified meetings — so humans can spend their time on conversations instead of clicks.
The part most definitions miss: a well-run AI SDR is signal-based, not spray-and-pray. It reaches out only to prospects showing intent — your inbound leads, or buying signals sourced from the web — never bulk cold blasts.
The job description
The same three jobs a human SDR has — minus the lunch break, the ramp time, and the CRM excuses.
Builds and refreshes prospect lists inside your ICP, watches for buying signals — job changes, funding, site visits, content engagement — and prioritizes who to contact today, not this quarter.
Writes personalized first touches and follow-ups across LinkedIn, email, and phone. The follow-up is the superpower: an AI SDR never forgets touch number six, and never gets discouraged by silence.
Handles the scheduling dance, qualifies against your criteria, and puts real opportunities on your closers' calendars — with the context of every prior touch attached.
The market
The label gets used for three very different things. Knowing which one you're buying is most of the decision.
Type 1 · Software
Pure software that runs outreach on its own. Impressive volume, but nobody's watching the quality — you (or someone you hire) still have to run it.
Type 2 · People
A traditional outsourced SDR agency that has bolted AI onto a people-heavy model. More judgment, but you're paying human prices for machine work.
Type 3 · Hybrid
AI runs the volume — one rep operating at the scale of a team* — while humans handle strategy, quality, and live conversations. This is the model SDR.ai runs.
The math
The economics are why the category exists. This is the working model behind an AI-powered SDR pod.*
| Metric | In-house SDR team | AI-powered pod |
|---|---|---|
| Cost per qualified meeting | $1,200+* | ~$350* |
| Annual cost (4-person team) | $360K+ fully loaded* | A fraction — see pricing |
| Time to ramp | ~6 months* | First signals in days* |
| Follow-up discipline | Depends on the rep | Never misses a touch |
