The Best AI SDR Agents for Small B2B Teams, Scored

A quick note on how this ranking landed, because the loudest brand on the shortlist finished last.

Walk into any B2B founder’s Slack in 2026 and the AI SDR conversation starts with 11x. The branding is sharp, the demos are convincing, and the “replace your SDR” pitch is engineered for an audience that’s quietly resentful of what SDRs cost. What that pitch leaves out is that Alice is a premium autonomous AI SDR priced from $3,750/month billed annually for up to 5 end users and 2,000 new prospects a month, with Pro and Enterprise custom-quoted . For a 5-to-30-person team, that’s an SDR salary on a channel you haven’t proven yet, and 11x bills annually by default with 2-3 year commitments carrying discount tiers on Pro and Enterprise, so you’re signing up for the whole experiment on day one.

Artisan won this ranking because it did something nobody else in the category did in 2026: it actually published pricing a small team can buy. Artisan now publishes self-serve credit-based tiers, Free with 300 credits/month, Intern at $280/month with 12,000 credits, Employee at $660/month with 30,000 credits, and a custom Enterprise tier for higher volume . There’s no seat minimum, no demo required, and the Free tier lets you push credits through a real campaign before you commit a dollar. That’s the trade a small B2B team wants: a reversible decision, not a procurement project. The credit model is the catch, plans are metered by credits (data enrichment + sends), not seats , so heavy senders burn through Intern faster than the headline suggests. The honest move is to start Free, measure your own credit burn, then size up.

AiSDR takes second because it’s the only one that gives you a human on the vendor side. The Explore plan at $900/month includes 1,200 AI messages, 1,200 lead search credits, unlimited seats, and a dedicated GTM engineer; the Grow plan at $2,500/month includes 4,500 of each; and Enterprise is custom . The tradeoff is the commitment shape: AiSDR offers only quarterly and annual billing with quarterly as the default, and the quarterly plan requires upfront payment of $2,700 for Explore or $7,500 for Grow . If you can swallow a quarter and you want a GTM engineer in your Slack while you figure the motion out, this is the one. If you can’t, the $250/month Solo plan is the only truly month-to-month way into AiSDR.

Regie.ai’s placement is the one most readers will be surprised by. Regie now pitches RegieGO as “an agentic sales workspace with built-in enrichment, emailing, dialing and workflows that gets you prospecting end to end from a single chat,” with a “Start free” option on the homepage and channel orchestration across email, LinkedIn and phone from a single platform. That’s a different product posture than Regie’s legacy enterprise sales engagement platform, and it’s the version a small B2B team should look at. Headline tier pricing isn’t shown on the product homepage, so confirm current numbers on Regie’s own pricing page before you commit.

Reply.io with Jason AI is a solid fourth. Jason is widely regarded as the most mature AI SDR agent in the category, and the model-choice flexibility is a real differentiator. But the economics work against a small team. Email Volume starts at $49 per user/month on annual billing, Multichannel at $89 per user/month, and Jason AI SDR starts at $500/month , and Jason is a separate product not included in any Sales Outreach plan, with the starter tier beginning at $500 per month annual ($800 to $1,000 monthly) supporting 1,000 to 3,000 active contacts, and the growth tier around $1,500 per month annual supporting 5,000 to 10,000 active contacts . You’re stacking a per-seat engagement platform under an AI agent, and the stack adds up. If you’re already standardized on Reply.io, Jason is the obvious upgrade path. If you’re starting fresh, Artisan or AiSDR cover more of the job for less money.

If you’re a small B2B founder reading this and thinking “but I still want to see what the agent writes before I buy it,” the two tools that’ll actually let you do that are Artisan’s Free tier and Regie.ai’s RegieGO “Start free” option. Everything else in this field wants your signature before your inbox.

The surrounding stack matters here too. An AI SDR is only as good as the list it works and the follow-up that chases the replies. If your prospect data is thin, start with the research layer. Our Clay review covers the most powerful prospecting tool for small B2B teams and the credit meter that comes with it. If the sequences themselves are what’s generic, our ranking of the best AI cold email personalization tools for small B2B teams is the place to go. And if the problem is actually what happens after the first reply, see our picks for the best AI sales follow-up and sequence tools for small B2B teams.

One honest caveat on the whole category. These numbers are a snapshot. AI SDR pricing moved more in 2026 than any other sales software category we track. Artisan dropped from a reported $1,500+/month enterprise contract to a $280/month self-serve tier in a single release cycle, Regie repositioned around the new self-serve RegieGO workspace, and 11x’s own pricing page and FAQ have disagreed with each other on the Alice Growth price all year.
