AI "digital workers" for sales, Alice runs autonomous outbound; Julian is an AI voice agent.
Best forMid-market and enterprise sales teams that want to scale outbound and inbound-calling capacity with AI digital workers and can run a proper pilot.
Our verdict
11x is one of the most visible bets in the "AI SDR" category: Alice runs the whole outbound motion, research, list-building and multi-channel sequencing, while Julian adds an AI voice agent for calls, both pitched as always-on digital workers that plug into your CRM.
A heavily-funded, capable AI-SDR play worth a pilot, but buy on your own measured results, not the marketing, given its 2025 credibility questions.
The Agents Index digest
New agents, fresh verdicts, and who's earning the top spots. One short email.
What's great
- Covers the full outbound motion autonomously, research, list-building and multi-channel sequencing in one worker.
- Adds an AI voice agent (Julian) on top of text outbound, and integrates with major CRMs.
Watch-outs
- Even the published Growth-tier price requires a "talk to sales" call rather than self-serve checkout, and Pro/Enterprise pricing is entirely custom with no public figures — still hard to evaluate full-program ROI up front.
- Reputation risk: in March 2025 TechCrunch reported 11x used logos of non-customers (e.g. ZoomInfo, Airtable) and former staff cited high early churn; founder Hasan Sukkar stepped down as CEO two months later (May 2025), replaced by then-CTO Prabhav Jain.
- Fully-autonomous AI SDRs remain hit-or-miss on deliverability and reply quality — independent tests report mixed results, so a pilot is essential.
- API access is uneven across the two products — Alice, the more widely-used SDR agent, only gets an API on the Enterprise tier, so most self-serve Alice buyers have no programmatic access.
Also note: Enterprise, sales-led product, expect annual contracts and onboarding, not a self-serve trial. · Autonomous outbound quality varies by list and configuration; monitor deliverability and reply rates closely.

What is 11x?
11x builds autonomous AI "digital workers" for revenue teams. Its flagship, Alice, is an AI SDR that runs outbound end to end, researching prospects, building lists and sending multi-channel sequences across email, LinkedIn and more. Julian is an AI voice agent that handles phone conversations: qualifying inbound calls, following up and booking meetings. Both are pitched as always-on workers that operate with minimal supervision and plug into your CRM. Founded by CEO Hasan Sukkar, 11x has raised roughly $76M total, a 2023 pre-seed, a $24M Series A led by Benchmark (September 2024) and a $50M Series B led by a16z (November 2024), and is headquartered in San Francisco with an original London office retained. It is one of the most-funded names in the "AI SDR" category, though it has also drawn notable scrutiny over past customer and revenue claims.
What does 11x do?
Alice automates the SDR workflow: she researches accounts and contacts using external data sources, assembles target lists, writes personalised messages and runs coordinated outbound sequences across channels, aiming to book qualified meetings without a rep touching each step. Julian works the phone, an AI voice agent that answers or places calls, qualifies leads in natural conversation, handles follow-ups and schedules meetings. Both connect to CRMs like Salesforce and HubSpot plus tools such as Slack, Gmail and calendars, and both are marketed as "digital workers" that run around the clock with light human oversight. 11x sells to sales and marketing teams that want to scale pipeline generation without proportionally scaling headcount. Pricing is partly published: Alice's Growth tier starts at $3,750/month and Julian's Growth tier starts at $2,417/month (chat) or $5,333/month (voice), all billed annually, but every tier, including Growth, still routes through a "talk to sales" call rather than self-serve checkout, and Pro/Enterprise figures stay entirely custom. It's worth being clear-eyed here: in March 2025 TechCrunch reported that 11x displayed logos of companies (including ZoomInfo and Airtable) that said they weren't customers and hadn't granted permission, and former staff described high early churn via contract break-clauses; six weeks later, in May 2025, founder Hasan Sukkar stepped down as CEO to become Non-Executive Chairman, and then-CTO Prabhav Jain succeeded him. The category is real and the product is genuinely capable, but results vary and the space is noisy, evaluate with your own pilot rather than on marketing claims.

11x review
11x is one of the most visible bets in the "AI SDR" category: Alice runs the whole outbound motion, research, list-building and multi-channel sequencing, while Julian adds an AI voice agent for calls, both pitched as always-on digital workers that plug into your CRM. Backed by a16z and Benchmark, it’s genuinely capable and the underlying category is real. But the caveats are significant and well-documented: pricing is custom and sales-led with no free plan, autonomous SDR quality varies enough that independent tests report mixed results, and in March 2025 TechCrunch reported the company had displayed logos of firms that said they weren’t customers, alongside former-staff accounts of high early churn, issues that preceded a leadership change. Pick 11x if you’re an enterprise team ready to run a rigorous paid pilot and measure deliverability and booked meetings yourself; skip it if you want transparent pricing, a free trial, or to buy on marketing claims rather than your own data.
A heavily-funded, capable AI-SDR play worth a pilot, but buy on your own measured results, not the marketing, given its 2025 credibility questions.
