AI SDRs, ranked by what they can replace today

The AI SDR demo goes like this. The agent finds the account, writes a sharp email, handles the reply and drops a meeting on an AE’s calendar, and someone on your side starts redrawing next year’s SDR budget. Then you ask for three references in your segment, at your deal size, and the vendor promises to follow up.

The incumbents now sell agents too. HubSpot, Outreach and Apollo build them into products you may already pay for, Salesforce has one in pilot, and most of them let you require a rep’s approval before anything reaches a buyer. The public case studies show agents paying off on a narrow job: research and first drafts for accounts you already know. The record for unsupervised outbound at volume is thin, and we weighted the ranking accordingly.

How we ranked them

RAC ranked these agents on the four things its desk weighs for each AI SDR it reviews: how openly and fairly each one prices, how much control buyers keep over what goes out under their name, the data and CRM sync behind it, and the independent record of results on review sites. The list covers agents that prospect outbound; inbound agents that answer website visitors in real time do a different job and are not ranked here. A thin independent record, or little control over what reaches buyers, keeps an agent off the list however well it does on the rest. Within the list, the order follows the desk’s scores, and the larger review record breaks ties. We read vendor product, pricing, help and terms pages, review sites and independent reporting in October 2026. We did not test the products, and any result labeled vendor-reported comes from the vendor. The ranking is the desk’s editorial judgment on that public record.

1. 1ApolloContact data and sequencing plus agents that research, build lists, write outreach, follow up and book meetings, with a 4.7 G2 rating on more than 9,000 reviews.Best for: SMB and mid-market teams that want data and agent prospecting from one vendor, starting on a free tier.Watch out for: more than 600,000 companies draw on the same 240 million-plus contacts, and in September 2026 a federal judge declined to dismiss a suit alleging that Apollo lists Colorado residents’ cell numbers without their consent; the case is pending.
2. 2AmplemarketThe Duo copilot pairs AI intent signals with deliverability tools on every plan, including a domain health center and a spam checker. The entry price is public, and G2 reviewers rate it 4.6 across 690 reviews.Best for: smaller teams that want copilot help and domain protection, starting at $600 a month for two users on an annual term.Watch out for: Duo Voice starts on the custom-priced Growth plan, and Amplemarket’s pricing post puts Duo Inbox on Elite, which is also custom-priced.
3. 3TopoSignal-based outbound by email and LinkedIn, with AI-drafted sequences and campaign advice from Topo’s own experts, from $89 a seat a month. Reps can approve each lead and message, Topo says, and G2 reviewers rate it 4.9 across 121 reviews.Best for: small and mid-size teams that prospect by email and LinkedIn and want outbound experts in the subscription.Watch out for: Topo’s own comparison pages list phone outreach as unavailable, and Salesforce sync comes only on the Enterprise plan, from 10 seats.
4. 4AiSDRAn outbound agent priced in public, from $250 a month for 200 AI-researched contacts to $2,500 for 2,500, with domain warmup, bounce checks and domain health tracking on its plans, and a 4.6 G2 rating on 102 reviews.Best for: solo sellers and small teams that want a priced, month-to-month outbound agent on HubSpot, with Salesforce sync on the Scale plan.Watch out for: its help center says AiSDR does not support a review-before-sending mode, so first-touch emails go out unreviewed; you can pause outbound, handle replies yourself and read the outreach logs instead.
5. 5UnifySignals from more than 40 data sources, enrichment, AI copywriting and multichannel sequencing in one product, with self-serve seats from $20 a month and a $40 million Series B led by Battery Ventures in 2025.Best for: lean teams that want a few reps or GTM engineers to run signal-based outbound without a large SDR floor.Watch out for: signal-triggered automations, managed mailboxes, website intent and read-write CRM sync all sit on the custom-priced Business plan. Only manual email steps wait for a rep’s review, and automatic steps send without one.
6. 6Salesloft (with Clari Forecast)Account research, person research, buyer identification and AI email steps inside Cadence, with Clari Forecast from the same company since Salesloft and Clari completed their merger in December 2025.Best for: Salesloft customers who want agents to handle research and first drafts while reps run the sequence.Watch out for: attackers used stolen Drift OAuth tokens to pull data from customers’ Salesforce instances in August 2025, and pricing is not published.
7. 7OutreachThe enterprise sequencing incumbent now runs agents for research, personalization and deals, with audit trails on every action and ISO/IEC 42001 certification, and its customers’ AI credit use grew 12x in the first half of 2026.Best for: enterprise teams already on Outreach that want central governance before agents touch customers: per-feature AI switches and an audit trail of agent actions.Watch out for: prices are not published, and each tier caps AI credits between 10,000 and 100,000, with extra packs sold on top.

Salesforce’s Hunter is too early to rate. It has the widest scope of any agent here, from prospect research to proposals over weeks and months, with an option to require rep approval on any action that reaches a customer. But it stays in pilot until a planned November general availability, Salesforce has not published a price, and the claim that it builds 60% of Perk’s pipeline is Salesforce’s own. Revisit it after launch with a reference customer in hand.

Outside the seven

HubSpot’s Prospecting Agent ranked first here until Oct. 13. It publishes a price, $1 for each lead it recommends for outreach, and it can run in review mode, and HubSpot said nearly 14,000 customers had activated it by its first-quarter 2026 earnings call. Outside HubSpot, the record is thin. No review site lists the agent itself, and across G2, Capterra, TrustRadius and Trustpilot the desk found 8 reviews that discuss it or HubSpot’s Breeze AI. The outcome figures the desk found all come from HubSpot. That is too little independent evidence to rank it yet.

Regie.ai, eighth here until Oct. 13, now sells RegieGO, a self-serve prospecting workspace its co-founder introduced on Aug. 25, 2026: enrichment, email from the seller’s own Gmail or Outlook and a dialer that runs up to nine lines, from $49 a month. The reviews the desk could read on G2 and Capterra all predate RegieGO, so the product on sale has no independent record of its own yet.

11x and Artisan sell the most autonomy, pointed at the job with the thinnest public record: outbound at volume with little human review. Artisan’s pricing page lists no prices, though its comparison pages advertise plans from $250 a month. 11x sells Alice, an outbound agent listed from $3,750 a month billed annually (its FAQ separately says 11x starts at $36,000 a year), and Julian, an inbound phone agent, and says it has raised more than $70 million from a16z and Benchmark. In March 2025, TechCrunch reported that 11x had claimed customers it did not have, including ZoomInfo, and 11x said it removed inaccurate mentions when asked.

Artisan, known for its “Stop Hiring Humans” campaign, describes its agent Ava as “Autonomous by default, adjustable by design,” with an option to approve messages before they send. The company had 40 employees in April, when co-founder and CEO Jaspar Carmichael-Jack told TechCrunch’s Build Mode podcast: “We’ve probably hired over 100 people to have the 40 people that we have now.”

ZoomInfo’s Agent Teams went live in GTM Studio on Oct. 1, too recently to judge.

How they charge

Vendors bill for what they think they are selling. HubSpot charges $1 for each lead its agent recommends for outreach. AiSDR charges by the contacts its agent researches, from $250 a month for 200 to $2,500 for 2,500, which lands at $1 a contact on its largest plan. Amplemarket starts at $600 a month for two users, Topo, Unify and Regie.ai sell seats that carry monthly credit allowances, Outreach sells seats plus AI credits at prices it does not publish, and Salesforce has not priced Hunter.

Read the unit before the rate. A dollar per recommended lead and a dollar per researched contact sound alike, and you pay both before a prospect replies. Thomas Randall of Info-Tech Research Group made the point about HubSpot’s unit in September: a recommended lead “has yet to respond, attend a meeting, enter pipeline, or generate revenue.” Convert each quote to cost per held meeting with your own conversion rates, and ask each vendor whether you pay again when the agent reworks the same accounts.

Where agents pay off

The strongest public examples share two traits: known accounts with rich first-party context, and a human on the send button. Clay describes a four-agent system its sales team uses for enterprise outbound, with agents for CRM history and call transcripts, outside signals, the buying center and the email draft. Clay says one of its reps spent more than 85 minutes researching each account before writing an email and now gets the research and a drafted sequence in under five minutes. Every rep reviews and edits the drafts before sending, and Clay uses those edits as training data.

Outreach reports that a SolarWinds win-back agent drew a 45% reply rate, reactivated more than 100 accounts and reopened $200,000 of pipeline. Salesforce says Hunter builds 60% of Perk’s pipeline. Both figures are vendor-reported, and the SolarWinds number comes from a play aimed at former customers who already knew the brand.

Where they fail

Volume is where the first wave of AI SDRs broke. Actively AI co-founder Anshul Gupta, whose company sells a competing approach, told TechCrunch in 2025 that AI SDRs had “failed” by chasing “pure volume,” contacting as many potential customers as possible. Mailbox providers police exactly that. Yahoo requires bulk senders to keep spam rates below 0.3% and to honor unsubscribes within two days.

Gartner also estimates that only about 130 of the thousands of vendors selling agentic AI are real, and calls the rebranding of chatbots and assistants as agents “agent washing.” Make each vendor on this list show you which steps its agent finishes without a person.

Copy quality is the quieter failure. Regie.ai reviewers on G2 this year complained about wrong prospect titles and about drafts in a generic, hyperbolic style that one reviewer said modern consumers have learned to ignore. Multiply one forgettable draft by an agent’s weekly volume and the bill lands on your domain reputation.

Each connected app is another set of keys to your CRM. Google’s threat intelligence team traced a wave of data theft from Salesforce instances in August 2025 to compromised OAuth tokens tied to Salesloft’s Drift app, and told customers to restrict connected-app scopes and rotate credentials. An agent with write access to your CRM and your mail server deserves the same review your security team gives any connected app.

What to measure in a 60-day pilot

A pilot that counts meetings booked will flatter any agent. Run the agent against a human holdout on matched accounts, and score it on four numbers.

• Held meetings and stage-two opportunities per 1,000 accounts touched, compared with the holdout.
• Spam complaint and bounce rates for each sending domain, with Yahoo’s 0.3% spam-rate ceiling as the hard stop.
• Edit rate, the share of agent drafts reps change before sending. A rate that falls while held meetings hold steady means the drafts are improving, and a flat rate means your reps are ghostwriting for the agent.
• Fully loaded cost per qualified opportunity, counting licenses, credits, domains and the RevOps hours to run it.

Name the steps of the SDR job you will hand to an agent after the pilot, starting with research and first drafts, where the public evidence sits. Then decide who keeps the send button, and what held-meeting number the agent must beat before that person lets go.

Corrections: On Oct. 10, 2026, this story was corrected because it said 11x publishes no prices; 11x lists entry prices for both of its agents. On Oct. 12, 2026, it was corrected again on four points. It said Artisan publishes no price; Artisan’s pricing page lists none, but its comparison pages advertise plans from $250 a month. It presented the $36,000 a year in 11x’s FAQ as the price of the $3,750-a-month plan; they are separate figures. It called Outreach’s controls approval controls; Outreach documents governance controls, not a step to approve messages before they send. And it implied Unify’s Series B came this June; it came in 2025.

Update: On Oct. 13, 2026, RAC re-ranked this list on the four criteria its desk now applies to each AI SDR it reviews: pricing, control, data and the independent record of results. HubSpot’s Prospecting Agent, previously first, and Regie.ai, previously eighth, moved outside the list because neither has an independent record for the product on sale today. Topo joined at third. AiSDR, previously left off because it has no review-before-sending mode, joined at fourth, because the desk now also weighs the controls it does document: a pause on all outreach, manual reply handling and outreach logs. Salesforce’s Hunter, previously sixth, moved to a note as too early to rate. The other tools’ facts are unchanged; their order changed.
