What is an AI SDR? Meaning, how it works and cost
An AI SDR (AI sales development representative) is software that does the job of a human SDR: it finds people who fit your offer, researches them, gets their contact details, writes outreach, follows up and books meetings for whoever closes the deal. That is the AI SDR meaning in one line: the prospecting half of sales, done by an AI agent. Outbound AI SDRs go after new prospects. Inbound AI SDRs answer people who already came to you. Either way, a person still takes the meeting and closes.

Outbound and inbound AI SDRs
- Outbound AI SDRs build a list of people who haven’t heard of you and start the conversation by email, LinkedIn or phone. 11x, Artisan, AiSDR and Amplemarket sit here.
- Inbound AI SDRs respond to website visitors, form fills and replies, qualify them and book meetings. Qualified’s Piper and Salesforce’s Agentforce sit here.
Even Salesforce says inbound is the easier job: “the most sophisticated AI SDRs today are better suited to tackling inbound leads” (Salesforce, 2025). Outbound is harder: the AI has to find the reason to write.
How an AI SDR works, step by step
- You describe who you sell to. Industry, size, job titles and the problem you solve.
- It builds a list. From a contact database, from buying signals such as hiring, funding and job changes, or from leads already in your CRM.
- It researches each person. Company, recent posts, news and tools.
- It qualifies them. It checks each lead against your rules and ranks the best fits first.
- It finds contact details. Work email, phone number and profile links.
- It writes the outreach. A first message tied to something real about the person, then the follow-ups.
- It sends, or waits for you. Some AI SDRs send on their own. Others draft and wait for your approval.
- It handles replies. It answers simple questions, stops when someone says no and offers times to people who say yes.
- It hands off. A booked meeting lands in your calendar with notes on why the lead fits.
What an AI SDR can’t do
- Fix vague targeting. If you can’t say who you sell to, it can’t either.
- Hold a real sales conversation. Pricing, objections and negotiation still need a person.
- Earn trust on its own. It can open a door. People buy from people.
- Guarantee deliverability. Heavy cold email from new domains can still land in spam.
Do AI SDRs actually work?
Yes, for the research and repetition. An AI SDR checks every company that fits, never forgets a follow-up and has a draft ready while a signal is fresh. It disappoints when it’s pointed at a broad market, sends without review and is judged on volume. The fix is the same as for a human SDR: a sharp ideal customer, a dated reason to write to each person and a check before anything goes out in your name.
AI SDR vs human SDR, in brief
| AI SDR | Human SDR | |
|---|---|---|
| Research and lists | Fast, every day, at any volume | Good, but takes much of the week |
| Live calls and objections | No, or only scripted | Yes |
| Time to start | Days | Recruiting, then months to ramp |
| Cost | A monthly plan or usage fee | A salary, plus tools and management |

How teams use an AI SDR
- Instead of a first hire. A founder or consultant uses an AI SDR to find and contact leads, then takes the calls themselves.
- Alongside human SDRs. The AI handles research and first drafts, so the rep spends the day in conversations.
It’s still early. In Bridge Group’s 2025 SDR Metrics Report, AI SDRs appeared as a category for 1% of respondents.
How AI SDRs are priced
Five common models, with prices from each vendor’s own site, checked November 2026.
| Model | How it works | Example |
|---|---|---|
| Per seat | A flat monthly fee per user, with usage credits included. | bravabase: $99 per user a month (pricing). |
| Credits | A plan buys credits; each person contacted uses some. | Artisan Intern: $280 a month, or $250 billed yearly, for 10,000 credits, about 500 people contacted (Artisan). |
| Pay per prospect | No monthly fee; you pay for each person reached. | AiSDR: $1.50 per person prospected (AiSDR). |
| Platform contract | A large monthly fee on a yearly term, sized by users and prospects. | 11x Growth: from $36,000 a year, billed yearly (11x). Amplemarket Startup: $600 a month, yearly term (Amplemarket). |
| Usage or quote | Priced per action or conversation, or only through sales. | Salesforce Agentforce: Flex Credits at $500 per 100,000 (Salesforce). Qualified Piper: quote only (Qualified). |
Before comparing prices, ask what one unit buys: a lead found, a person contacted or a conversation.
How to choose an AI SDR
- Inbound or outbound? If your problem is unanswered demo requests, you want an inbound agent. If it’s an empty pipeline, outbound.
- Who presses send? Decide whether you’ll approve each message or let the agent run. If your name is your business, approve.
- Which channels do your buyers answer? Email, LinkedIn, phone or a mix. Pick a tool that works where they reply.
- What’s the commitment? Monthly with a trial, or a yearly contract after a demo.
- Run a small test. Give it 100 people you know fit and read every message it writes before scaling up.

Questions about AI SDRs
Do AI SDRs actually work?
Yes, for the research, list building, first drafts and follow-ups. Results depend on what you give them: a clear ideal customer, a real reason to write to each person and someone checking the messages. Pointed at a vague market with no review, they send generic messages at volume, and that is where most complaints come from.
What are the best AI SDR platforms?
For outbound: bravabase if you want ready-to-buy leads and to approve every message, Artisan or 11x for autonomous outbound email, AiSDR to try one with no monthly fee and Amplemarket for signal-based outbound with approval. For inbound: Qualified’s Piper or Salesforce’s Agentforce if you already run on Salesforce.
Who are the big 4 AI agents?
There is no official list. In AI SDR roundups the four names that come up most are 11x’s Alice, Artisan’s Ava, AiSDR and Qualified’s Piper. Alice, Ava and AiSDR do outbound; Piper answers inbound leads on your website and by email.
What is Salesforce SDR?
Agentforce SDR is Salesforce’s AI SDR agent, now called Agentforce Engagement. It works leads and contacts in Salesforce: it sends intro and follow-up emails, answers replies and questions, books meetings and hands qualified leads to sales reps. Salesforce also bought Qualified, the maker of Piper, in April 2026.
Is an AI SDR the same as an AI sales agent?
Nearly. An AI sales agent is the broad category. An AI SDR is a sales agent built for one job: starting conversations and booking meetings for someone else to close. See what an AI sales agent is.
Are AI SDRs legal?
Yes, when they follow the same rules a person would. Cold email in the US must follow CAN-SPAM: a real sender, your postal address and a working opt-out. In the EU, GDPR and each country’s e-privacy rules apply, and some countries need consent before a cold email. Since February 2024 the FCC treats AI-generated voices as artificial under the TCPA, so AI cold calls need prior consent. LinkedIn’s user agreement bans tools that automate activity on the site, so a tool that sends for you can put your account at risk.
How much does AiSDR cost?
$1.50 per person prospected, with no monthly fee. Team plans are quoted. See AiSDR pricing.
