[Amplemarket](https://agentsindex.ai/amplemarket) starts at $600 a month, billed annually. Digital workers for outbound sequences and inbound calls come from [11x](https://agentsindex.ai/11x-ai), whose Growth plan costs $3,750 a month billed annually. On 8 November 2026 we listed 398 tools: 21 of them under Sales Agents and 198 with a free plan. - Clay has the cheapest flat-priced entry plan, at $185 a month, or from $167 a month billed annually. - Clay and Apollo each have a free plan, 2 of the 4. - Buying from 11x starts with sales: it offers no self-serve signup and no free tier. Clay and Apollo both let you sign up yourself and start on a free tier. - Clay and 11x keep your data out of AI model training, 2 of the 4, while Amplemarket’s terms take a perpetual license to analyze uploads with machine learning, with no published opt-out. ## Pick by what you need - [Start free and build your own research agents](#clay) Clay Free, then $185 a month Free plan mentions no call or card and carries 500 actions - [A small team paying per rep, with no card to start](#apollo) Apollo Free, then $65 a seat a month Bills per seat - [Agents that qualify leads and run outreach](#11x) 11x $2,417 a month billed annually Its Lead Qualification scores and filters prospects before handoff - [Message variations written and tested for you](#amplemarket) Amplemarket $600 a month billed annually Duo Copywriter writes and tests message variations for each sequence - [A written uptime promise](#clay) Clay Free, then $185 a month Publishes a service-level agreement **Skip all of these** if you need to run the agent on your own servers: Every pick runs as a hosted service, and none offers a deployment on your own infrastructure. ## The 4 picks side by side Table 1 Price and the questions that separate them, checked 5 November 2026 Product From Limits on what it may do Free tier Retention you control Best for [Clay](https://agentsindex.ai/clay) Free, then $185 a month Yes Yes Partly teams building their own enrichment workflows [11x](https://agentsindex.ai/11x-ai) $2,417 a month billed annually Partly No Yes handing outreach to autonomous digital workers [Apollo](https://agentsindex.ai/apollo) Free, then $65 a seat a month Yes Yes Partly reps wanting data, sequences and pipeline together [Amplemarket](https://agentsindex.ai/amplemarket) $600 a month billed annually Partly Partly Yes reps who approve every send [How we check](https://agentsindex.ai/methodology) ## How much should the agent do without a rep? Choose the level of control first: Clay and Apollo let you set how far the agent goes, 2 of the 4. What the 11x digital workers may read and write in your CRM is configurable. Clay gives every task and schedule a permission level, from approval gates on live runs to unattended work, and Apollo makes every action reviewable and widens autonomy only as you allow. ## What does it cost to start, and can I try it first? Clay and Apollo let you start free, and Clay has the cheapest flat-priced paid entry, at $185 a month. Clay also offers a 14-day free trial, and its Launch plan runs from $167 a month billed annually. Apollo charges by the seat. Amplemarket’s Startup plan is $600 a month, billed annually, with a 7-day trial you request on the Startup card. The Growth plan of 11x costs $3,750 a month billed annually. ## Can I sign up myself, or does it start with a sales call and a contract? Clay and Apollo let you sign up and buy online, 2 of the 4; Amplemarket and 11x start with a form or a sales call. Clay sells Free, Launch and Growth from its pricing page and routes only Enterprise through a demo, and its plans cancel from the Billing screen at any time. Apollo runs sign-up, plan purchase and its 14-day trial without sales contact. Amplemarket prints a figure only for Startup, routes Growth and Elite through a form and sets licenses, price and duration in an Order Form, billed annually. Every 11x tier starts with Talk to sales, billing is annual, and fees are non-cancelable. ## Where does the prospect data come from? Apollo, Amplemarket and 11x search lead data built into the product, while Clay pulls from outside sources. Clay pulls from sources such as ZoomInfo, Clearbit and Crunchbase. Apollo enriches spreadsheet, CRM and API records with verified contact data from its own database. 11x includes a real-time company and lead database for list building, and Amplemarket’s Searcher finds prospects with search filters and auto-enrichment. ## What happens to my customer data? Clay and 11x keep your data out of AI model training, 2 of the 4, and 11x and Amplemarket let you decide when your data is deleted, 2 of the 4. Clay excludes training by contract for itself and its model providers, and the 11x contract forbids training models on your data while allowing its use to improve the service. Amplemarket takes a perpetual license to analyze uploads with machine learning, with no published opt-out, and purges customer data on request or when the contract ends. Under the 11x privacy policy, the customer decides how long personal data is kept. ## Does it connect to my CRM and to ChatGPT or Claude? Clay, Apollo and Amplemarket each run a hosted MCP server, and 11x documents none. Apollo lists connectors in Claude, ChatGPT and Perplexity on any plan, including free, and Clay lets admins choose which clients connect and cap each rep’s credit spend. Clay’s Sequencer works with Salesforce, HubSpot, Outreach and Slack. Amplemarket pushes sends, replies, calls and meetings as events to an address you register. 11x opens its research agent to other agents through the Agent Connect program. ## The tools that stand out ### [Clay](https://agentsindex.ai/clay) **Best for teams building their own enrichment workflows:** Each column of its table calls a data provider, runs an AI research step or triggers an outbound action, and every plan includes unlimited seats. Price Free, then $185 a month Clay is a table where each row is a lead, company or account and each column calls a data provider, runs an AI research step or triggers an outbound action. Claygent, its research agent, works inside those columns, and buying signals from LinkedIn, Google and Reddit help rank accounts when intent changes. Its hosted MCP server lets other agents run its find-and-enrich tools, with admins capping each rep’s credit spend. The free plan carries 500 actions and 100 data credits a month, unlimited seats and Claygent access, capped at 200 rows per table. Launch costs $185 monthly or from $167 a month billed annually, and Growth $495 monthly or from $446 a month billed annually, with a 14-day free trial. Every plan includes unlimited seats, so the bill follows usage rather than headcount. Spend runs on two meters: Actions for each enrichment or automation step, and Data Credits for the data itself, from $0.05 each. Actions never roll over, while Data Credits bank up to twice the monthly amount. Clay also has a sequencer that hands leads to Salesforce, HubSpot, Outreach or Slack. **What it does well** - A standing free plan with unlimited seats, 500 actions and 100 data credits a month. - A published 99.0% monthly uptime promise with tiered service credits. - Each task and schedule carries a permission level, from approval gates on live runs to fully unattended runs. **Where it falls short** - Two meters, Actions and Data Credits, have to be modeled together to predict a bill. - Exporting data out of Clay is a metered action, and deletion takes 30 days to complete. - The public API reads tables only, and paging past 100 rows needs Enterprise API table sync. - **Free plan:** yes; 14-day free trial - **Who it’s for:** Go-to-market teams with someone who will build and maintain enrichment and outreach logic, since Clay is designed around that operator role. - **Skip it if:** Reps who want to log in and start sending should look at Apollo, which wraps its contact data in list building, sequencing, a dialer and meeting scheduling. ### [11x](https://agentsindex.ai/11x-ai) **Best for covering outbound and inbound with one vendor:** Alice runs outbound sequences across email, LinkedIn, phone and text, and Julian answers inbound calls. Price From $2,417 a month billed annually The vendor sells two digital workers: Alice, an outbound sales development rep that researches prospects and runs sequences across email, LinkedIn, phone and text, and Julian, an inbound phone agent that answers calls, qualifies leads and books meetings. Campaigns launch from ready-made playbooks filled in on a form, and native two-way connectors cover Salesforce, HubSpot, Pipedrive and Zoho on every plan. What the worker may read and write in your CRM is configurable. Growth costs $3,750 a month billed annually, or $45,000 a year, for up to 5 users and 2,000 new prospects a month, with managed Gmail mailboxes and CRM sync included. Pro and Enterprise are custom-quoted and there is no monthly plan. Every tier starts with a sales conversation, with no free plan or trial published. TechCrunch reported in March 2025 that several customer logos on its site belonged to companies that had only run brief unpaid pilots. Its Checkr case study now names Checkr employees by title with attributed quotes. **What it does well** - Alice and Julian cover outbound sequences and inbound calls, so one vendor runs both ends of the funnel. - Campaigns go live from a form-based playbook. - Two-way CRM connectors for Salesforce, HubSpot, Pipedrive and Zoho come on every plan. - The customer decides how long personal data collected through the service is kept. **Where it falls short** - Contracts are annual with no monthly plan, so a bad first quarter still costs a year. - Buying starts with a Talk to sales button on every tier. - Prepaid credits are non-refundable when you leave. - **Who it’s for:** Sales and revenue operations teams that want prospecting and lead qualification run by agents and can commit to an annual contract. - **Skip it if:** Teams that want to try before a contract should look at Clay or Apollo, which both let you start on a free plan. ### [Apollo](https://agentsindex.ai/apollo) **Best for reps wanting data, sequences and pipeline together:** Apollo puts a contact database, email sequencing, a dialer and meeting scheduling in one workspace, starting from a standing free plan. Price Free, then $65 a seat a month Apollo sells access to a business contact database and the tools to act on it. Its actions run inside Salesforce, Gmail and a Chrome extension through Apollo Anywhere, and its hosted MCP server, available on any plan including free, brings them into Claude, ChatGPT and Perplexity. Every action is reviewable, and autonomy widens only as far as the buyer allows. The Free plan never expires and carries 75 credits per seat a month, 2 sequences per team and 250 daily email sends. Paid plans bill per seat: Basic is $49 a seat a month billed annually, and Professional $99 a seat a month billed monthly or $79 billed annually, with a 14-day trial. Organization carries a three-seat minimum. Credits buy the work, at 1 credit for an email and 8 for a phone number. They are pooled across the team and expire each cycle, add-on credits included. Where Clay bills for usage with unlimited seats, Apollo’s bill grows with each seat you add. **What it does well** - A standing Free plan at $0 that includes 250 daily email sends and the hosted MCP server. - Sign-up, plan purchase and the 14-day trial all run online. - Its MCP server works on every plan, free included. - Salesforce, HubSpot and Pipedrive integrations come on every plan. **Where it falls short** - No uptime percentage or service credit is published. - Unused credits expire every cycle, including purchased add-on credits. - The Free plan caps the AI Assistant at 5 chats and allows 2 sequences per team. - **Free plan:** yes - **Who it’s for:** Reps and small revenue teams who want to start free and buy seats online. - **Skip it if:** Teams that need a written uptime promise should look at Clay or Amplemarket, which both offer one. Apollo’s Terms disclaim any guarantee of uninterrupted service and promise only commercially reasonable efforts. ### [Amplemarket](https://agentsindex.ai/amplemarket) **Best for teams that want an open API and event pushes:** Its public API is open to every account, and events for sends, replies, calls and meetings push to an endpoint you register. Price From $600 a month billed annually Amplemarket’s Duo agents scan the market daily for signals such as a closed-lost prospect looking again, a visit to your site or a poor review of a competitor, then draft a personalized multichannel sequence for each buyer. Searcher finds prospects with auto-enrichment, Duo Inbox gathers replies in one inbox, and Duo Voice adds AI calls with voice cloning. Admins alone edit the prompts that steer it, such as per-signal nudges and competitor battlecards. Startup costs $600 a month on an annual term with 2 users included, and Growth and Elite are custom. Startup carries 27,000 contacts, 13,500 email address credits and 600 phone number credits per user per year. The free trial runs 7 days on Startup, and the contract renews itself unless you give notice 60 days before the term ends, with renewal fees capped at a 7% increase. A public API open to every account, an MCP server on every plan and event pushes for sends, replies, calls and meetings connect it to other tools, including two-way Salesforce sync and Clay. Where Apollo starts on a free plan, Amplemarket starts on a paid annual plan that turns signals into drafts. **What it does well** - Duo turns buying signals into drafted multichannel sequences for each buyer. - The public API is open to every account, and the MCP server comes on every plan. - Events for sends, replies, calls and meetings push to an endpoint you register. **Where it falls short** - When the contract ends, the terms oblige you to delete all data sourced from the platform. - The agreement renews automatically unless you give notice 60 days before the term ends. - Amplemarket does not rule out training on your data. - **Who it’s for:** Sales teams that want AI to find the signals and write the first draft. - **Skip it if:** Teams that want a standing free plan to start on should look at Apollo or Clay, since Amplemarket’s free access ends with its trial. ## Prices compared Figure 1 · Entry price, a month Entry prices in US dollars run from $185 a month to $2,417 a month; the median is $600 a month 1. Clay $185 a month 2. Amplemarket $600 a month 3. 11x $2,417 a month Source: Each vendor’s pricing page, read between 3 November 2026 and 4 November 2026. [How we check](https://agentsindex.ai/methodology) Clay sits at the low end at $185 a month, and Amplemarket’s Startup plan costs $600 a month, billed annually. Apollo bills by the seat instead, so its cost grows with each rep you add. > “Clay will use commercially reasonable efforts to make the Covered Services Available for 99.0% of time measured monthly, other than due to an Exception” From [Clay’s own page](https://www.clay.com/legal/sla), read on 25 October 2026 ## How we compared We compared 4 tools on price, free plan and 24 questions about what they do, reading each vendor’s pricing page and product pages between 3 September 2026 and 5 November 2026.
