The best AI SDRs, tested and ranked

11x came first of six with 2.5 out of 5, with the top flexibility and integrations scores in the group at 3. Its agent got 66 of 100 messages right on the first pass, retries fixed 24 of the 34 failures, and alerts caught 7 of 10 problems. It also had the most no-code connections, 7 of 10. Set-up was slow, at 133 minutes.

11x sells two AI agents. Alice researches accounts and runs email and social outreach from mailboxes 11x sets up and warms for you, with two-way sync to HubSpot, Salesforce or Pipedrive. Julian talks to inbound leads by voice or chat and books meetings. It's the only tool here that covers both outbound and inbound.

It's also the most expensive, sold on annual contracts with no free trial and no published refund policy. In March 2025, TechCrunch reported that 11x had shown logos of companies that said they weren't customers; 11x blamed human error, and its founder stepped down as CEO two months later. It holds 4.2 out of 5 on Trustpilot from 37 reviews (checked November 2026).

Artisan came second with an even 2.5 out of 5 on every part. Its agent, Ava, matched 11x with 66 of 100 messages right on the first pass, retries fixed 21 of the 34 failures, and alerts caught 7 of 10 problems. Set-up took 124 minutes, and 6 of the 10 connections we needed worked without code. Our Artisan review covers the full test.

Artisan bundles everything for outbound in one product. Ava finds leads in a database of more than 250 million B2B contacts, writes and sends outreach from your own domains, answers replies and books meetings. You can require approvals, lock the tone and call to action, and set escalation rules, which we'd keep on.

Prices aren't published: every plan is quoted by lead volume, and refund terms aren't stated. In December 2025, LinkedIn banned Artisan for about two weeks over alleged data-broker scraping, and users say its LinkedIn outreach doesn't work as expected. It has 4.1 out of 5 on Trustpilot from 42 reviews (checked November 2026), with credits running out quickly a common complaint.

Qualified Piper came third with 2.5 out of 5. It was the easiest to set up, at 103 minutes, which earned its best score of 3. But reliability was its weak spot at 2: only 59 of 100 messages were right first time, retries fixed 27 of 41 failures, and alerts caught 6 of 10 problems. Our Qualified Piper review explains more.

Piper is a different kind of AI SDR. Instead of chasing cold leads, it talks to people already on your website by video, voice or chat, follows up by email and books meetings, using your CRM and intent data. Our test was an email campaign, so it doesn't capture Piper's website conversations, which are its main job.

Salesforce completed its purchase of Qualified on April 1, 2026, and Piper is being folded into Salesforce's Agentforce plans. It lists SOC 2 Type II, but data is stored only in the US, and every plan is quoted after a demo, with no free plan or trial.

Boundo came fourth with 2 out of 5. Only 57 of 100 messages were right on the first pass, and set-up was the slowest in the test at 134 minutes. Its retries rescued 27 of 43 failures and its alerts caught 7 of 10 problems, and 6 of the 10 connections we needed worked without code.

Boundo is a small, Y Combinator-backed AI sales rep for outbound. You describe your ideal customer in a chat or upload a list, and it finds leads through third-party data providers, writes personalised messages and sends LinkedIn actions and email sequences. It adds intent tracking, a shared inbox and sync with HubSpot, Salesforce and Pipedrive.

There's a lot we couldn't confirm. Boundo publishes no prices, we found no independent user reviews, and we found no security certifications. For a tool that writes to prospects in your name, we'd want all three before signing.

AiSDR came fifth with 2 out of 5. It got 58 of 100 messages right on the first pass, but retries fixed only 23 of 42 failures and its alerts caught just 5 of 10 problems, the fewest in the test. Set-up took 126 minutes, and 6 of 10 connections worked without code. Read our AiSDR review.

AiSDR runs outbound over email and LinkedIn, with call tasks and video or voice notes, and its agent Ami helps you pick an audience and build campaigns. It reads recent posts and company news before writing, handles common questions and objections, and books meetings. It syncs both ways with HubSpot and Salesforce.

Its big draw is price. It's the only tool here with a published pay-as-you-go rate, $1.50 per person prospected, billed daily with no monthly fee, and you can build campaigns without a card. Team plans for 1,000+ contacts a month are quoted and come with a dedicated GTM engineer. Refund terms aren't published, and we couldn't confirm any security certifications.

Regie.ai came last of six with 2 out of 5. Only 55 of 100 messages were right on the first pass, the lowest in the test, retries fixed 25 of 45 failures and alerts caught 6 of 10 problems. Set-up took 127 minutes. Our Regie.ai review has the full results.

That ranking says more about what we tested than about what Regie.ai is for. Its RegieGO workspace is built for people who sell, not to run outbound on its own. You describe your ideal customer in a chat, and agents find and rank accounts, look for reasons to reach out now, write messages in your voice and prepare calls, with a built-in CRM and a power dialer.

It's by far the cheapest way into this category. The free plan gives you 250 one-time credits with no card, Pro is $49 a month and Team is $150 a seat a month, with no contract on either. Credits reset each period without rolling over, and fees and credits are generally non-refundable.
