The 9 Best AI SDR Tools

By Vinay Patankar · Edited by Vinay Patankar · Published November 14, 2026

At a glance

The best AI SDR tool for most SaaS teams that want one agent across outbound, inbound and voice is 11x. AiSDR is the easiest to try, with self-serve pricing per person contacted, and Artisan suits teams that want an AI BDR with its own contact database and onboarding team. Qualified is the pick for inbound website leads, and HubSpot's prospecting agent fits teams already on HubSpot.

The best AI SDR tools promise something sales leaders have wanted for years: prospecting that keeps running after the team logs off. An AI SDR (sales development representative) is software that finds leads, researches them, writes outreach, handles replies and books meetings, with a human seller stepping in once a conversation is real. The category has grown fast, and the products now differ a lot in what they automate, who they suit and how they charge.

This guide compares nine AI SDR tools for SaaS sales teams. Each entry covers what the product does, who it fits, its strengths and limits, and what the vendor publishes about pricing, so you can match a tool to the gap in your pipeline rather than to the loudest launch.

What AI SDR tools do

An AI SDR tool automates the top of the sales funnel. Where a human sales development rep spends the day building lists, researching accounts, writing first touches, following up and booking meetings for account executives, an AI SDR runs those steps as software. The AI SDR entry in the Library covers the concept in depth. In practice, the tools on this list fall into three groups:

Outbound agents find target accounts and contacts, research each one, write personalized sequences and send them from your domains. 11x, AiSDR, Artisan, Agent Frank and Valley lead with this.
Inbound agents answer website visitors and form fills in real time, qualify them and book meetings with the right rep. Qualified is built for this, and 11x covers it alongside outbound.
AI inside an existing sales platform adds an agent to tools a team may already own, such as HubSpot’s prospecting agent or Amplemarket’s Duo, so the AI works where the data and sequences already live.

Every tool still needs a human somewhere. Most let the team approve messages before they send, set banned phrases and tone, and decide when a reply escalates to a person. The best results come from teams that treat the agent like a new hire: clear targeting, a good brief, close review in the first weeks and more autonomy as it earns trust.

How these tools were judged

Each tool was judged on five questions:

How much of the SDR job does it cover? Finding leads, research, writing, replies and booking are separate jobs. A tool that covers all five removes more work than one that only drafts emails.
Can you control it? Approval modes, tone settings, guardrails and handoff rules matter, because an unchecked agent can damage sender reputation and brand trust quickly.
How does pricing scale? Per seat, per contact and per lead pricing behave very differently as volume grows. Published pricing scores higher than “talk to sales” for teams that want to test first.
Does it fit your stack? CRM sync with Salesforce or HubSpot, your own sending domains and calendar booking are the minimum.
Who is it built for? Some products assume an enterprise rollout with a dedicated success team, others a founder with a credit card.

Product facts come from each vendor’s own website and pricing page, fetched on the publish date. Customer results quoted by vendors are labeled as the vendor’s claim. Where a vendor does not publish a price, this guide says so rather than guessing.

1. 11x

11x describes itself as a provider of AI sales agents for inbound, outbound and expansion. Its agents work across voice, chat, email, social and SMS. On the inbound side, voice and chat agents contact, qualify and book meetings around the clock in multiple languages, and 11x says every inbound lead is answered in under a minute, with chat agents engaging on the website or phone agents calling back form fills. On the outbound side, the platform covers a real-time company and lead database, live web search and AI prospecting, deep research, multi-channel sequences, smart replies and multilingual outreach.

The breadth is the reason it ranks first. One vendor covers speed-to-lead, outbound prospecting, event follow-up, closed-lost reactivation and customer expansion, with deliverability and mailbox health tools, CRM and Slack integrations, and an API. Customer stories on its site mention its agents by name, including Alice and Julian.

Best for: teams that want one AI agent layer across outbound, inbound and expansion.

Pros:

Covers inbound and outbound in one platform, including AI phone agents.
Multi-channel: voice, chat, email, social and SMS.
Built-in lead database, web research and deliverability tools.
A long list of plays, from speed-to-lead to competitive takeouts and closed-lost outreach.

Cons:

No published pricing; buyers book a demo.
The breadth means more setup and more decisions than a single-channel tool.
Better suited to teams with real volume than to a solo founder testing outbound.

Pricing: not published. The site routes buyers to book a demo.

2. AiSDR

AiSDR is an AI SDR platform that says it focuses on lead quality over volume. Its agent, Ami, finds people across the web with problems the seller can solve, researches them and writes outreach meant to sound like a team’s best rep. AiSDR says Ami was trained on 18,000 campaigns across 27 industries, and the platform includes AI prospecting, an AI strategist for outreach plans, and two-way CRM sync with HubSpot and Salesforce, plus an Aircall integration for calls.

The standout is how easy it is to start. The pricing page offers self-serve, pay-as-you-go pricing with no sales call, charged daily, with the option to stop at any time. Research, lists and writing cost nothing extra; you pay for the people you reach.

Best for: teams that want to try an AI SDR without a sales call or a long contract.

Pros:

Published, usage-based pricing with no contract required.
Research, list building and writing are included in the per-person price.
Optional warmed-up mailbox and managed services for teams without sending infrastructure.
HubSpot and Salesforce sync.

Cons:

Per-person pricing can add up quickly at high volume; larger teams are pointed to a sales-led plan.
Email-first, with less on inbound chat or voice than 11x or Qualified.
Managed services are a separate cost.

Pricing: $1.50 per person prospected on the self-serve plan. Add-ons include a warmed-up mailbox for $33, a per-campaign managed service for $149 per campaign, and a fully managed service for $2,500 per month. The pricing page says teams that contact 1,000+ people a month can talk to sales about a Teams plan.

3. Artisan

Artisan’s AI BDR, Ava, finds leads, enriches them, sends personalized messages and books meetings on behalf of a team’s reps. Artisan positions Ava two ways: running alongside an existing stack, with two-way CRM sync and outreach sent as each rep, or as the whole outbound stack, consolidating data, sequencing, dialing and booking in one platform with a built-in database of 250M+ contacts.

Control is a focus. Artisan says teams can approve messages before sending, lock tone and calls to action, set banned phrases and coach Ava’s writing. Ava sends in reps’ names from the company’s own domains, handles replies and passes meetings to reps. Calls are added to reps’ task lists, with an AI dialer sold as a per-seat add-on.

Best for: outbound teams that want an AI BDR with data and onboarding support built in.

Pros:

Built-in contact database and enrichment, so no separate data contract is required.
Strong guardrails: approvals, tone locks and banned phrases.
Every plan includes CSM support and guided onboarding.
SOC 2 Type II certified, with SSO and SAML.

Cons:

No published prices; every plan is scoped with sales.
Calls are handled by reps with a dialer add-on, not by an AI voice agent.
Salesforce and HubSpot are the named CRM syncs, so teams on other CRMs should check fit.

Pricing: not published. The Team plan is sized at about 2,500 leads contacted per month and Scale at about 6,000, with Enterprise custom. Artisan says plans are sized to lead volume, mailboxes and dialer seats.

4. Qualified

Qualified sells Piper, an AI SDR agent built to generate inbound pipeline. Piper meets buyers in real time on the website, engages inbound leads by email, schedules sales meetings instantly and serves personalized marketing content, with a Slack integration for the team. Qualified’s pricing page lists a multi-modal agent that works across text, voice and video, with multi-language support.

Qualified is closely tied to Salesforce. Every plan includes Salesforce CRM integration and reporting, waterfall enrichment for account segmentation and routing for conversations, emails and meetings. Qualified says Piper has been hired by over 500 companies.

Best for: inbound website leads, especially for marketing and sales teams on Salesforce.

Pros:

Built for inbound: website conversations, email follow-up and instant booking.
Multi-modal and multi-language.
Deep Salesforce integration plus 20+ go-to-market system integrations.
Clear plan structure by web sessions and email contacts.

Cons:

Inbound-first, so it is not a replacement for an outbound prospecting agent.
No published prices.
Best value assumes meaningful website traffic.

Pricing: not published. Premier includes 1 SDR agent profile, 250K monthly web sessions and 2.5K monthly active email contacts. Enterprise raises those to 2M sessions and 10K contacts and adds agent handoff and MCP and API access. Ultimate adds multiple agent profiles and a dedicated IP address. Every tier is “Contact us.”

5. HubSpot Prospecting Agent

HubSpot’s prospecting agent is an AI sales automation tool built into HubSpot Sales Hub. It monitors accounts for buying signals such as funding rounds, leadership changes and site visits, sources and enriches contacts, and drafts personalized outreach in each rep’s voice. It integrates with ZoomInfo, Apollo, Surfe and Seamless to find contacts across buying committees.

Teams can review and edit every AI-drafted email before it sends, then switch to a fully autonomous mode once they trust the output. Research criteria, messaging style and engagement rules can be configured per product or persona.

Best for: teams already running sales on HubSpot.

Pros:

Lives inside the CRM, so there is no new tool or sync to manage.
Review mode first, autonomous mode when ready.
Connects to several third-party data providers.
Clear per-lead pricing.

Cons:

Only useful for HubSpot customers.
Runs on HubSpot Credits, so costs depend on credit balances and edition.
Focused on prospecting and drafting rather than inbound chat or voice.

Pricing: HubSpot says the agent is priced per outreach recommended for a lead: $1 for each lead it recommends outreach for. It is available in the Starter, Professional and Enterprise editions and runs on HubSpot Credits.

6. Amplemarket

Amplemarket is an all-in-one sales platform for teams and AI agents. Its Duo AI layer powers research through to reply: Duo Copilot, Duo Accounts for choosing the best accounts to work, Duo Copywriter for personal first touches, Duo Inbox for replies and Duo Voice for creative outreach. Around it sit B2B data and signals, email, call and social steps in one workflow, and deliverability tools.

It suits teams that want AI SDR features without giving up a full engagement platform. Reps keep sequences and calling; the AI handles the research and first drafts.

Best for: teams that want AI agents plus a full sales engagement platform.

Pros:

Data, signals, sequencing, calling and deliverability in one product.
AI covers account selection, copy and replies.
Published starting price and a free trial on every plan.

Cons:

The Startup plan is billed on an annual term.
Growth and Elite pricing is custom.
More of a platform than a fully autonomous agent, so reps still drive the work.

Pricing: Startup is $600 per month on an annual term with 2 users included. Growth (4 users included) and Elite (10 users included) are custom. Additional users can be purchased, and all plans include a free trial.

7. Agent Frank

Agent Frank is the AI SDR from Salesforge. It runs automated prospecting around the clock in autopilot or co-pilot mode, searches a database of 500M+ contacts and writes outreach in 20+ languages. Because it sits inside Salesforge’s suite of products, it can use the company’s own tools for email infrastructure, warm-up and lead generation instead of separate vendors.

Salesforge is clear about fit: B2B companies with deal sizes between $5K and $100K, selling to decision-makers at startups, SMBs or mid-market companies, targeting 3,000 or more businesses. Agent Frank is available only after a demo, and each customer gets a dedicated account manager and a shared Slack channel.

Best for: high-volume cold email to SMB and mid-market buyers.

Pros:

Published price with a clear per-contact cost.
Autopilot and co-pilot modes.
20+ languages and a 500M+ contact search engine.
Dedicated account manager.

Cons:

Requires a demo before you can start.
Billed quarterly or annually rather than monthly.
Email infrastructure is an add-on.

Pricing: $499 per month billed quarterly, covering 2,000+ contacts a month, which Salesforge works out to $0.25 per contact.

8. Valley

Valley is an outbound tool that finds the right prospects, researches what matters to them, writes messaging in the seller’s voice and sends outreach across email and social channels. It starts from signals such as lead magnet replies, people joining relevant conversations, companies hiring account executives and competitor complaints. Valley says the whole process, from signal to sent message, takes under 5 minutes.

The Starter plan is LinkedIn only, which makes Valley a fit for founders and teams whose buyers live on LinkedIn. Plus adds email and multichannel outreach with priority support and onboarding.

Best for: LinkedIn-first outbound for founders, small sales teams and agencies.

Pros:

Signal-based targeting rather than static lists.
Messages written in the seller’s own voice.
CRM, API and MCP integrations, including HubSpot.
Self-serve start with a 7-day trial.

Cons:

The entry plan is LinkedIn only.
Per-seat pricing grows with team size.
A payment method is required for the trial.

Pricing: Starter (LinkedIn only) and Plus (LinkedIn and email) are priced per seat per month; Plus is $299 per seat per month billed monthly. The pricing page shows two different Starter prices, so confirm the current figure before buying. Growth is also listed.

9. Regie.ai

Regie.ai’s RegieGO is built for reps who prospect themselves. It finds matching buyers from an ideal customer profile description, runs waterfall enrichment for emails and phone numbers (paying only when it finds them), surfaces dated why-now signals, drafts messages in the rep’s voice and includes a parallel dialer that calls up to five lines at once. A built-in CRM comes free on every plan and syncs with HubSpot or Salesforce.

It is less of an autonomous agent than the products above and more of an AI-powered prospecting workspace, which suits individual reps and small teams who want to stay hands-on.

Best for: individual reps and small teams who want AI prospecting plus a dialer.

Pros:

Free plan with no credit card.
Low published prices for individuals.
Parallel dialer and built-in CRM.
Sends from your own Gmail or Outlook.

Cons:

The rep still runs the motion; it is not a hands-off agent.
The parallel dialer needs a paid plan.
Team plan has a two-seat minimum.

Pricing: Free is $0 with 250 one-time credits per person. Pro is $49 per month billed monthly or $41 billed annually, for one person. Team is $150 per seat per month billed monthly or $125 billed annually, with a 2-seat minimum. Enterprise is custom.

How to choose the best AI SDR tools for your team

Name the gap first. Slow inbound response and thin outbound pipeline need different tools. Check where leads are lost before shortlisting.
Fix targeting before scaling. An AI SDR writes faster emails to whoever you point it at. A vague ideal customer profile becomes a fast route to spam folders.
Start in review mode. Approve every message for the first few weeks, then hand over the parts that prove reliable. Most tools here support approvals, tone controls and banned phrases.
Protect deliverability. Use separate sending domains, warm-up and mailbox rotation. Several vendors sell infrastructure as an add-on, so price it in.
Model cost at your real volume. Per contact, per lead and per seat pricing diverge quickly. Work out the monthly cost at the number of people you plan to reach.
Measure meetings and pipeline, not activity. Track meetings held, qualified opportunities and pipeline created per dollar, and compare against a human SDR’s fully loaded cost.

For the wider landscape, the best AI sales tools guide covers data platforms, dialers and conversation intelligence, and the best sales playbook software list covers keeping a team consistent once meetings start flowing. Real examples of what SaaS companies send prospects are in the Sales Templates library, and the company directory collects them by vendor. If buyers are researching vendors through AI assistants before they reply, the Library’s guide to answer engine optimization explains how those answers are assembled.

Mistakes to avoid when buying an AI SDR

Expecting it to fix messaging. If human SDRs cannot get replies with the current pitch, an AI SDR will send the same weak pitch at greater volume.

Skipping the brief. Agents need a clear description of the product, the buyer, common objections and proof points. Teams that skip this step get generic copy.

Sending from the main domain. High-volume outreach from a company’s primary domain risks the deliverability of every other email it sends.

Removing humans too early. The vendors on this list all describe reps owning live conversations. Plan the handoff before the first meeting is booked.

Comparing on list price alone. A cheaper tool that needs a separate data contract, mailbox service and dialer can cost more than an all-in-one plan.

Amplemarket, Agent Frank, Valley and Regie.ai fit more specific needs.

What does an AI SDR do?

An AI SDR automates the work of a sales development rep: finding leads, researching them, writing outreach, following up, handling replies and booking meetings. A human seller usually takes over once a prospect is ready for a real conversation.

How much do AI SDR tools cost?

Pricing models vary widely. AiSDR charges $1.50 per person prospected, HubSpot charges $1 per lead its agent recommends outreach for, Agent Frank starts at $499 per month billed quarterly, and Regie.ai has a free plan with Pro at $49 per month. 11x, Artisan and Qualified do not publish prices.

Can an AI SDR replace human SDRs?

Are AI SDRs good for inbound or outbound?

Both, but most tools specialize. Qualified is built for inbound website leads, while AiSDR, Artisan, Agent Frank and Valley focus on outbound. 11x covers both inbound and outbound, including AI phone agents.

How do you measure whether an AI SDR is working?

Measure meetings held, qualified opportunities and pipeline created, not emails sent. Compare the cost per qualified meeting with a human SDR’s fully loaded cost, and watch deliverability metrics such as bounce and spam rates so volume does not damage your domains.
