AI-powered sales development is no longer a novelty, it is now a core part of how B2B teams build pipeline. Two platforms that come up frequently in this conversation are Apollo and 11x. Both use AI to accelerate outreach, but they take fundamentally different approaches: one automates the SDR role entirely, while the other puts intelligent tools in the hands of your existing team.
If you are evaluating these platforms in 2026, the choice comes down to your go-to-market philosophy, budget, and how much human judgment you want in the loop. This comparison breaks down features, pricing, and real-world fit so you can make a confident decision.

Apollo is an AI GTM system that unifies data, intelligence, and execution into one connected GTM system. Sales professionals use Apollo to find the right contacts, research accounts, run multi-channel sequences, dial prospects, and enrich CRM records, without switching between disconnected tools.
The platform spans the full outbound and inbound motion, from initial prospecting through booked meetings.
Apollo meets sellers where they already work. Apollo MCP, Apollo's Model Context Protocol, connects Apollo's data and workflows directly into AI assistants including ChatGPT, Codex, Claude, and Perplexity, so GTM engineers and AI builders can trigger prospecting and enrichment actions from inside their AI environment of choice. The Chrome extension brings Apollo's database and sequencing tools to any web page. For technical and advanced users, Apollo CLI provides terminal-native access for headless GTM workflows.
Apollo's B2B database covers 240M+ people and 30M+ companies, with contacts continuously validated through Apollo's Living Data Network. The platform is trusted by 100K+ paying customers and used by 100+ teams at Fortune 500 companies, and has earned the 2026 MarTech Breakthrough Award for "Best AI-Powered Sales Solution" and recognition as a G2 Leader across multiple categories.
According to Ramp's vendor data, drawn from real spend observed across Ramp's platform, Apollo holds a 38% adoption rate among businesses that have purchased a Sales Data Providers tool, up 5 percentage points year-over-year as of July 2026. A 22% competitor switch rate means more than one in five Apollo customers previously used a different vendor in the category before switching.

Apollo offers transparent pricing starting at $49/user/month (annual billing), with a free tier available. The full tier breakdown is covered in the Pricing Comparison section below.

11x positions itself as a provider of autonomous AI digital workers for revenue operations. Its two flagship products are Alice, an AI SDR designed to handle outbound prospecting and multi-channel outreach, and Julian, an AI phone and chat agent that qualifies inbound leads in real time across voice, SMS, and WhatsApp.
Alice runs 24/7, sourcing prospects from more than 50 data sources, personalizing messaging, handling replies, and scheduling meetings, all without a human rep initiating or reviewing each action. Julian handles inbound qualification through voice calls, chat, and messaging channels, with the option to perform live call transfers to human reps.
The platform includes a managed email deliverability layer: every plan comes with domain setup, Gmail mailbox warmup, inbox rotation, and monitoring, so teams do not need to configure deliverability infrastructure separately. Bi-directional CRM sync is included across all tiers.
Multi-language outreach supporting 105+ languages is available on Alice Pro and Enterprise plans.
11x reports that Alice draws from 50+ data sources for buyer targeting and lead scoring, though the specific databases and accuracy figures are self-reported. SOC 2 Type II compliance is listed on the platform's website.
11x is designed for sales teams and RevOps organizations that want to add autonomous AI capacity alongside or instead of human SDRs. The model is particularly relevant for teams managing high contact volumes where fully automated sequences are acceptable and where the economics of replacing headcount with software make sense at scale.
Alice Growth plans start at $3,750/month (billed annually), and Julian Voice Growth starts at $5,333/month (billed annually). Pro and Enterprise pricing is available on request.
Full pricing details are in the Pricing Comparison section.

The comparison above highlights a fundamental structural difference: Apollo gives sales teams verified data, AI assistance, and execution tools they control, while 11x deploys autonomous agents that act on the team's behalf. Teams that want AI to augment their reps will find Apollo's model more familiar; teams that want to offload SDR work entirely will find 11x's approach more aligned with that goal.

Apollo's full pricing breakdown, available at apollo.io/pricing, is as follows (all prices are annual billing):
11x uses a per-lead pricing model rather than a per-seat model. Alice is priced per prospect contacted, not per email sent, meaning the cost stays the same whether Alice runs 3 touchpoints or 30 per contact. Pricing for Alice and Julian on the official 11x pricing pagebreaks down as follows (all annual billing):
11x's FAQ confirms the Alice Growth plan starts at $36,000 per year. Multi-year commitments are available and lock the current rate for the full term.
Price increases at renewal are capped. There are no setup or onboarding fees on any plan.
The pricing models serve different buying motions. Apollo's per-seat model scales with your team and lets individual reps and small teams start affordably. 11x's per-prospect model is designed for teams committing to a specific monthly outreach volume, with entry-level investment significantly higher than Apollo's self-serve plans.
Tired of watching marketing leads stall before they ever reach your reps? Apollo surfaces in-market buyers with verified contact data so your team hits pipeline targets — not guesses. Nearly 5M users can't be wrong.
Start Free with Apollo →The most important difference is where intelligence and execution live. With Apollo, a rep uses AI to research accounts, build sequences, and make calls, but the rep decides who to contact, reviews messaging, and manages relationships.
Apollo's AI Research Agent, AI Sequence Builder, and dialer all augment human judgment rather than replace it. For teams who believe relationship quality and rep skill matter to conversion rates, this approach keeps humans accountable for outcomes.
11x operates on the premise that the SDR role itself can be automated. Alice identifies, researches, sequences, and replies autonomously.
This can increase throughput without adding headcount, but it also means less visibility into individual outreach decisions and fewer opportunities for reps to develop skills or build direct relationships with prospects before a meeting is booked.
Apollo's data layer is also directly integrated into execution. Because Apollo owns its verified contact database, reps prospect, enrich, and sequence from the same system, with no need to import lists or reconcile records across tools. As Mark Turner, VP of Revenue Operations at Built In, puts it: "Apollo enriches everything we have: contacts, leads, accounts...And we don't really have to touch it, it just works."
Apollo also integrates across the tools teams already use. With 50+ integrations including Salesforce, HubSpot, Outreach, Salesloft, Orum, and Marketo, Apollo fits into existing stacks rather than requiring teams to route everything through a new system. Apollo MCP further extends this by bringing Apollo's data into AI assistant environments, giving GTM engineers and AI builders a way to build headless prospecting workflows without a UI.
According to Ramp's Sales Data Providers category data, Apollo is the fastest-growing vendor in the category as of July 2026, averaging +0.7 percentage points of adoption per month. Apollo also captured 33% of first-time category buyers, teams that had no prior Sales Data Providers vendor before choosing Apollo, placing it second in new-adopter capture for the category.

For teams already using Apollo who want to add autonomous SDR capacity, the two tools are not mutually exclusive. But for teams choosing a primary platform for their outbound motion, Apollo's broader capability set, transparent pricing, and human-in-the-loop model offer a different value proposition than 11x's fully autonomous approach.
Apollo is an AI GTM system where human reps use AI-assisted tools to prospect, sequence, dial, and enrich data. 11x deploys autonomous AI agents (Alice for outbound, Julian for inbound) that operate without a rep in the loop. The choice depends on whether you want AI to augment your team or act as a standalone SDR.
Apollo's AI Research Agent, AI Sequence Builder, and automated workflows handle many tasks that autonomous SDRs perform, account research, personalized messaging, follow-up scheduling, but with a human reviewing and approving actions. Teams that want full automation will find 11x's model more suited to that goal; teams that want AI assistance with human accountability will find Apollo's model more appropriate.
As detailed in the pricing section above, Apollo offers self-serve plans starting at $49/user/month (annual billing) with a free tier. 11x's Alice Growth plan starts at $3,750/month (annual billing), with Pro and Enterprise on requested quotes. The two platforms use fundamentally different pricing models: Apollo charges per seat, while 11x charges per prospect volume.
Yes. Apollo offers a free tier with 900 credits/year, allowing teams to explore prospecting, basic sequences, and database access before committing to a paid plan. 11x does not list a free tier; the Growth plan is the entry point.
Apollo serves B2B GTM teams, GTM Engineers, and AI Builders building headless GTM workflows with the Apollo API, CLI, and MCP, alongside Sales Professionals, SDRs/BDRs, AEs, RevOps, Marketing, and Revenue Leaders. Teams at any stage, from early-stage startups to companies with dedicated RevOps functions, use Apollo to consolidate prospecting, engagement, and analytics in one system.
As covered above, Apollo is used by 100+ teams at Fortune 500 companies as well as growing teams across all segments.

Apollo and 11x both apply AI to the sales development problem, but they reflect different assumptions about the role of human reps. 11x bets that autonomous agents can own the SDR function end-to-end; Apollo bets that AI works best when it makes human sellers faster and more informed. For most B2B teams, the question is not just what is possible with AI, but what model fits how your team wants to work.
Teams that want verified contact data, multi-channel engagement, a built-in dialer, and AI tools their reps can use immediately, without a six-figure annual commitment, will find Apollo delivers strong value across the full outbound and inbound motion.
