# What is an AI SDR?

An AI SDR is a software agent that performs sales development work — finding leads, qualifying them against an ICP, personalizing outreach, and booking meetings — with humans supervising instead of writing every message.

By Devansh Ranjan · Published Aug 23, 2026

An **AI SDR** is a software agent that performs sales development work: finding prospects, qualifying them, personalizing outreach, following up, and booking meetings. The human moves from writing every message to supervising an agent that drafts them.

## What an AI SDR does, step by step

1.  **Discovery:** finds candidate leads matching an ideal customer profile (ICP) — role, industry, size, geography.
2.  **Qualification:** scores each candidate against the ICP before any outreach time is spent.
3.  **Personalization:** researches the prospect and drafts messages for them specifically — the best systems generate per-lead assets like playbooks, not just merge fields.
4.  **Sequencing:** runs multi-touch outreach across channels, branching on replies and accepts.
5.  **Booking:** handles replies and proposes meeting times, with human approval at whatever level you set.

## Where the category is going

Two camps are forming: email-first AI SDRs running on B2B databases (Artisan, 11x) and social-channel agents running native LinkedIn and Instagram outreach (Sumora). The social camp argues DM replies out-convert cold email for SMB buyers; the email camp argues scale. Compare them directly in [Sumora vs Artisan](/compare/sumora-vs-artisan).

## Frequently asked questions

What does an AI SDR actually do?

The full SDR loop: lead discovery, ICP qualification, personalized outreach across channels, multi-touch follow-up, reply handling, and meeting booking — supervised by a human who approves messages or runs defined steps on autopilot.

How much does an AI SDR cost?

Flat subscriptions ranging from roughly $80/month for founder-tier tools like Sumora to $2,000+/month for enterprise AI SDR platforms like Artisan or 11x. A human SDR costs $60,000–$80,000/year fully loaded, which is why the category exists.

Are AI SDRs safe for LinkedIn and Instagram?

It depends on the tool. Agents built for social channels enforce per-account daily and weekly send ceilings with warm-up ramps — Sumora publishes its enforced limits publicly. Email-only AI SDRs face deliverability risk instead of account risk.

AI SDR vs AI BDR — is there a difference?

Practically, the terms are used interchangeably. Classically SDR = inbound-ish qualification, BDR = outbound prospecting; most 'AI SDR' products today do outbound prospecting, which is the BDR half.
