The best AI sales agent for most teams assists human reps rather than replacing them. Start with Clay or Apollo for research and sequences, HubSpot if that is your CRM, and Qualified for inbound. Fully autonomous AI SDRs such as AiSDR, Artisan, and 11x are worth a tightly measured pilot, not a headcount decision.
An AI SDR is software that does the work of a sales development rep: finding prospects, writing outreach, handling replies, and booking meetings. This category has more than its share of hype. Gartner predicted in June 2025 that over 40% of agentic AI projects would be canceled by end of 2027. It also warned about vendors rebranding old tools as agents.

How we chose
- We read vendor documentation and pricing pages. We did not run our own tests.
- We looked for tools that take sales actions, not just draft an email.
- We searched for independent failure reports and include the one we could verify directly.
- We skipped meeting and pipeline multipliers from testimonials, because they are not controlled tests.
- We checked email and calling rules at the source.
- The numbering is not a ranking. For underlying model positions, see the leaderboard.
The risks to read first
The failure report. TechCrunch reported in March 2025 that 11x claimed customers it did not have. Three current and former workers said most early customers used break clauses to leave. They cited issues such as the product not working as expected and hallucinations.
ZoomInfo told TechCrunch it ran a one-month trial and that the product "performed significantly worse than our SDR employees." Some of that reporting relies on unnamed sources, and it is more than 18 months old. Products change, so treat it as a reason to verify rather than as a verdict.
Email law. The FTC says each email violating CAN-SPAM can bring penalties of up to $53,088. It also says you cannot contract away your legal responsibility, even if you hire another company. An AI vendor sending under your name does not change that.
Voice calls. The FCC ruled in 2024 that AI-generated voices fall under the TCPA's rules on artificial voices. Such calls need prior express consent, absent an emergency or exemption. Have counsel review any AI dialing plan. This article is not legal advice.
1. HubSpot Prospecting Agent: for HubSpot users
Best for: Sales teams already on the HubSpot CRM.
Price: Sales Hub pricing starts at $7 a seat per month. Professional starts at $90 and Enterprise at $150, each with a one-time onboarding fee. Plans include 500 to 5,000 credits monthly, and extras cost $0.010 each.
The Prospecting Agent researches leads and delivers personalized outreach strategies. Living inside your CRM means it sees your past activity on the account. It also means replies and meetings stay on one record.
Most teams find adoption easier when the tool is already part of the rep's day. Keep reps reviewing outreach while you learn what the agent gets wrong. Credits reset monthly, so unused allowance does not carry forward.
Where it falls short: The page does not clearly state which tiers include the agent, so confirm with sales. It is only useful if you are on HubSpot.
Our take: The sensible first test for HubSpot teams. Compare replies from the agent's drafts against those of your best rep.
2. Apollo: data and sequences in one place
Best for: Small sales teams wanting contacts and outreach from one tool.
Price: Apollo's pricing page lists Free, Basic, Professional, and Custom. The dollar figures did not appear in the page text we could read, so check them in your browser. Annual plans cost less than monthly and lock you in for 12 months.
Apollo says you can run agents that work in the background. Its credits cover emails, phone numbers, email warmup, domains, mailboxes, and AI-researched data. They are pooled across your team and granted at the start of each billing cycle.
The all-in-one setup is good for a young team. You avoid wiring together a data vendor and a sending tool. The trade-off is less freedom to mix specialist tools later.
Where it falls short: Unused credits expire at the end of each billing cycle, including purchased add-on credits. Moving from annual to monthly means waiting until the annual term ends. Always verify data before a big send.
Our take: A strong default for early-stage outbound. Start on monthly until you know your usage.
3. Clay: research for skilled operators
Best for: Growth teams that want highly customized prospecting.
Price: Clay's pricing offers Free with 500 actions a month and Launch at $167 a month, starting at 15,000 actions. Growth starts at $495 a month.
Claygent, Clay's AI agent, does web research to produce custom data points. You could ask it which prospects have recently opened a new location, for example. Clay then feeds that data into your outreach tools.
This is the opposite of a set-and-forget product. Its value comes from an operator who can think of good signals and build the workflow. In the right hands, specific research beats generic personalization.
Where it falls short: It has a learning curve and is not a complete sending system by itself. Costs depend on the actions and data credits your workflow consumes, so build a small test before scaling.
Our take: The best fit if you have a person who enjoys building systems. Without one, it will sit unused.
4. Instantly: high-volume cold email
Best for: Small agencies and teams doing cold email at volume.
Price: Instantly's pricing lists the Outreach Growth plan at $47 a month. Bundles start at $94 a month. The Scale bundle at $194 a month adds the AI Reply Agent.
Instantly lists AI agents for sales, replies, and lead finding, plus a database of 450M+ B2B leads. The Growth plan includes unlimited email accounts and warmup. Its Reply Agent aims to handle and qualify replies at scale.
Volume is the risk here. Sending more bad email hurts your domain and your reputation at the same time. Keep cold outreach on a separate domain, and never send more than you can handle replies for.
Where it falls short: High-volume cold email invites deliverability trouble and CAN-SPAM duties. You must honor opt-outs within 10 business days and list a valid postal address. An AI reply to a confused prospect can cost you more than no reply.
Our take: A cost-effective sending engine. Add the Reply Agent only after you have read a few hundred of its answers in draft mode.
5. AiSDR: pay as you go
Best for: Smaller teams wanting to test an AI SDR without a long contract.
Price: AiSDR's pricing is $1.50 per person contacted. Pay as you go is charged daily, and Team plans are billed monthly on quarterly contracts.
The simple unit makes the math easy. If you contact 1,000 people, the bill is about $1,500. You can compare that directly with a rep's fully loaded cost and your likely meetings.
Paying per contact does not reward quality, though. Your costs depend on how many people you reach, not how many meetings you get. So your own targeting is doing most of the work, and you should watch your cost per meeting.
Where it falls short: Per-person pricing adds up fast if your list is poorly targeted. Add-ons exist for extra research and campaigns. It is designed for B2B outreach, so consumer lists raise different rules.
Our take: A clean way to run a contained pilot. Run it on one segment for a set period, then calculate your cost per qualified meeting.
6. Artisan: an AI BDR named Ava
Best for: Teams that want one vendor for leads, outreach, and dialing.
Price: Talk to sales. Artisan's pricing page describes a Team plan at about 2,500 leads contacted a month, with price scoped to your plan.
Artisan's company overview describes Ava as an autonomous AI BDR. Ava finds and enriches leads, writes outreach, and handles parts of the conversation. Artisan says it has a database of 250M+ contacts. Plans are scoped to lead volume, mailboxes, and dialer seats.
The "AI employee" pitch is appealing to a founder with no sales team. Be careful, though. Outbound still depends on a clear offer and a good target list, and an agent can't invent those for you.
Where it falls short: No public price, and credit-based plans make direct comparison harder. Ask about contract length and exit terms, because those were at the center of the 2025 reporting about this category.
Our take: Worth a pilot if you have a proven offer. If your offer is unproven, spend your money learning from real conversations first.
7. 11x: autonomous outbound and voice
Best for: Larger teams evaluating autonomous outbound and inbound agents.
Price: Book a demo. 11x's site shows no public price.
11x's site describes agents for outbound, inbound, and expansion, with Alice on outbound and Julian on voice. It lists lead generation, multi-channel sequences, smart replies, and consented outbound calling. Testimonials on its site report strong results.
Read those alongside the TechCrunch report above. The company and product may have changed since March 2025, and you should not assume either way. Ask directly for references you can call yourself.
Where it falls short: No public pricing, and the past reporting makes independent verification especially important. Check any logo or customer claim with the customer. Negotiate a break clause and clear success criteria.
Our take: Only consider it with reference calls and a measured pilot. The same standard should apply to any autonomous SDR you evaluate.
8. Qualified Piper: for inbound, not cold outreach
Best for: B2B teams with meaningful website traffic.
Price: Contact sales. Qualified's pricing page lists plan limits such as SDR agent profiles, monthly web sessions, and email contacts, and routes you to a contact form.
Piper talks to buyers on your website in real time. It can also handle email, book meetings, and work with your team in Slack. Qualified's plans all include an agent studio and account segmentation.
Inbound has a built-in advantage: these people came to you. An agent answering a live visitor faces less legal and reputational risk than one cold-emailing a stranger. It is usually the better first AI sales project for a company with traffic.
Where it falls short: It needs enough site traffic to justify the cost, and the sales process is quote-based. Its self-reported ranking claims are marketing, so judge it by your own conversions.
Our take: Our favorite starting point for B2B teams with traffic, because the risk is lower. Measure qualified pipeline, not just chats.
9. Outreach: agents for established sales teams
Best for: Mid-size and large sales organizations.
Price: Request pricing. Outreach's pricing combines seats with consumption-based AI credits.
Outreach lists agents for research, personalization, revenue, deals, and meeting preparation, along with coaching and forecasting tools. The agents sit on top of a full sales engagement platform. It suits teams that already have sequences and managers in place.
The seat-plus-credit mix makes budgeting harder than a flat price. Ask for a usage estimate based on your rep count and your activity. Also ask what happens if you exceed it.
Where it falls short: It is too heavy for a small team. It needs real operations support to run well. The page has vendor performance claims, which you should test yourself.
Our take: A natural extension for existing Outreach customers. New buyers should compare it against their CRM's built-in agents first.
How to choose
Work up the autonomy ladder rather than jumping to the top:
- Research assistance: Clay or your CRM's agent finds signals, and reps write.
- Draft assistance: The agent writes, and reps approve each message.
- Inbound: An agent answers visitors who came to you.
- Supervised outbound: An agent sends to a small, carefully chosen segment.
- Autonomous outbound: Consider this only if the earlier stages worked.
Run a controlled pilot. Split a target list between the agent and a rep, then compare meetings held and qualified pipeline, not emails sent. Our agent evaluation scorecard can help, and our agent vs hire comparison frames the cost question.
Ask each vendor for these before signing:
- A break clause or short pilot term.
- Customer references you choose, not only ones they choose.
- Who owns the data and the sending domains.
- How opt-outs are honored across all channels.
- What your actual cost per meeting has been for similar companies.
Set human approval rules with our approval decision table. For the underlying models, see the leaderboard and its methodology. Remember that those benchmarks do not test sales outcomes.
Frequently asked questions
Do AI SDRs actually work?
Sometimes, and mostly with a good offer and a tight list. TechCrunch's 2025 reporting describes early customers leaving one vendor, while vendors publish strong case studies. Neither tells you about your market, so run your own measured pilot.
How much does an AI SDR cost?
Public figures include $1.50 per person contacted at AiSDR and $47 a month for Instantly's Outreach Growth plan. Artisan, 11x, and Qualified need a quote. Add your data, mailbox, and supervision costs.
Is AI cold email legal?
CAN-SPAM rules apply to commercial email however it is written. The FTC cites penalties of up to $53,088 per violating email, and other countries have stricter rules. Have counsel check your program.
Can AI make sales calls?
The FCC has ruled that AI-generated voices are covered by the TCPA. Such calls generally need prior express consent unless an emergency or exemption applies. Do not launch AI dialing without legal review and consent records.
Should I replace my SDR team with an agent?
We would not start there. Test agents on the tasks your team dislikes, then compare results over a full sales cycle. Keep someone responsible for quality, because an agent's mistakes reach prospects directly.
