11x

11x is an AI SDR platform built to replace the manual labor of outbound sales development. Its two agents, Alice for email and LinkedIn prospecting and Jordan for voice calls, work autonomously to research prospects, write personalized outreach, follow up through multi-step sequences, and book meetings directly into sales rep calendars. Founded in 2022 by Hasan Sukkar, 11x raised a Series B in 2024 and now serves over 200 revenue teams. Pricing starts at $1,500/month.

Most sales teams reach the same wall eventually. Outbound pipeline depends on SDR headcount, SDR headcount costs money, and scaling output means hiring more people who then need onboarding, management, and quota structure before they produce anything useful. 11x was built around the idea that this wall doesn't have to exist if the prospecting work itself can be done by software. Its two agents, Alice and Jordan, are designed to replace the top-of-funnel labor that a traditional SDR team handles, at a fraction of the cost per meeting booked.

Quick verdict

11x earns serious consideration for any revenue team with an established outbound motion and the ICP clarity to configure an AI SDR properly. Alice is one of the most capable outbound email agents available at the enterprise level. Jordan's voice capabilities add a dimension most competitors lack. The $1,500/month entry price and the absence of a trial period make it a considered purchase rather than an impulse buy, but for teams spending that much or more on SDR headcount per month, the math typically works.

What is 11x, exactly?

11x is an AI sales development platform founded in 2022 by Hasan Sukkar, with offices in San Francisco and London. The platform raised a Series B funding round in 2024 and counts over 200 revenue teams as customers. Its core product is two AI agents: Alice handles outbound prospecting across email and LinkedIn, and Jordan handles voice calls for inbound qualification and outbound follow-up.

The platform sits in the AI SDR category, which has grown significantly since 2023 as sales teams looked for ways to run outbound at scale without proportional headcount increases. Where many AI writing tools require a human to press send, 11x's agents operate autonomously through full sequences, handling research, personalization, follow-up timing, and meeting booking without waiting for a rep to approve each action.

The company's fundraising trajectory and customer count suggest product-market fit among mid-market and enterprise sales organizations. It's not a tool for a three-person startup figuring out its first outbound email, but it's well-suited to a 20-person sales team that needs to double its top-of-funnel output without doubling its SDR line.

The two agents at the center of the platform

Alice: outbound email and LinkedIn SDR

Alice is the product most 11x customers deploy first. She operates as an AI sales development representative for outbound channels. The workflow starts with defining your ICP: the industries, company sizes, titles, and signals that indicate a strong potential buyer. Alice then researches prospects within that profile using real-time web data, LinkedIn signals, and company news, and uses that research to write personalized outreach rather than templated mass email.

What makes Alice different from a mail merge or a basic AI writing assistant is sequence management. She doesn't just write one email and hand off. She manages the full follow-up cadence, tracking who responded, who needs another touch, and when to pull a prospect from the sequence because they've shown no engagement. That logic runs without a human managing the queue.

The personalization quality varies with the ICP specificity. Teams that have done the work to identify exactly who they're targeting and what signals they respond to get noticeably better results than teams that configure Alice with a broad target and hope the AI figures out the rest. The output quality reflects the quality of the input configuration.

Jordan: voice AI for calls and qualification

Jordan is the voice component of the 11x platform and the feature that distinguishes it from competitors focused exclusively on email and LinkedIn. Jordan can handle inbound lead qualification calls, following up on web form submissions or demo requests by calling the prospect, qualifying them against your criteria, and booking a meeting with an account executive if they meet the threshold.

On the outbound side, Jordan can make calls as part of a multi-channel sequence, adding a phone touchpoint to campaigns where email alone isn't getting a response. The call quality and natural conversation capability has improved significantly since the initial release, though voice AI for sales still requires careful monitoring to catch edge cases where the conversation goes in an unexpected direction.

For teams with a high volume of inbound leads who don't have the SDR bandwidth to call everyone within an acceptable response window, Jordan solves a real problem. Speed to lead matters in outbound sales, and an AI that calls within minutes of a form submission versus a human who calls the next day often produces meaningfully different conversion rates.

Multi-channel sequence coordination

One area where 11x has invested more than simpler AI writing tools is the coordination of outreach across channels without requiring a human to manage the handoffs. Alice handles email and LinkedIn. Jordan handles voice. The sequences can be configured to include touchpoints across all three in a logical order without requiring a sales manager to manually move contacts between tools.

That coordination matters because multi-channel sequences consistently outperform single-channel campaigns in terms of response rate, but building and managing those sequences traditionally requires more SDR time per prospect, not less. 11x's approach moves the coordination overhead to software rather than to headcount.

The CRM sync keeps all of this visible to the sales team. Every touchpoint Alice sends, every call Jordan makes, and every meeting booked flows back into Salesforce or HubSpot automatically. Sales managers see pipeline activity in their existing tools without requiring a separate dashboard or a manual reporting process.

Pricing and what you get

11x's pricing starts at $1,500/month for entry-level access. Enterprise plans are custom and scale with the number of agents deployed, outreach volume, and the depth of CRM integration required.

There is no free tier and no self-serve trial. Evaluating 11x means going through a sales process, which is consistent with how enterprise sales tools typically work but can be a friction point for teams that prefer to test software before committing.

The $1,500/month entry point needs context to evaluate fairly. A single SDR in a major market costs $60,000 to $90,000 annually in salary alone, before benefits, tools, and management overhead. If Alice produces meetings at a meaningful fraction of what a human SDR generates, the economics favor the AI significantly. The teams where this math doesn't work are those with low outbound volume, highly technical or relationship-driven sales motions where personalization needs to go beyond what AI research can produce, or organizations that haven't yet defined their ICP clearly enough to configure the agents effectively.

Where 11x wins and where it doesn't

11x wins on autonomous operation. If you configure Alice and Jordan correctly, they run without requiring daily human management. That's genuinely different from tools that use AI to assist a human sending emails versus tools where the AI is doing the sending. For teams that want outbound running continuously without SDR oversight on every sequence step, 11x is one of the few platforms built for that model.

It also wins on the voice dimension. Most AI SDR platforms are email-first with LinkedIn as a secondary channel. Adding autonomous voice calls to the mix is a meaningful capability gap over competitors that 11x is one of the first to close at scale.

Where 11x is harder to recommend is for teams that don't yet have a proven outbound motion. Deploying an AI SDR into an undefined sales process produces AI-generated noise rather than pipeline. The platform is most valuable as an accelerant for teams that already know their ICP, their messaging, and their conversion benchmarks, not as a tool for figuring those things out.

The lack of a trial period is a genuine barrier to entry for teams with reasonable procurement caution. Having to commit to $1,500/month without hands-on evaluation is a harder sell when alternatives like Artisan or Lindy offer lower entry points.

How 11x compares to the alternatives

11x vs Artisan: Artisan's Ava focuses on email and LinkedIn with strong data enrichment capabilities. 11x adds voice through Jordan, making it a broader multi-channel platform. Artisan's $1,200/month entry is slightly lower, but for teams where voice outreach is part of the mix, 11x covers ground Artisan doesn't.

11x vs Regie.ai: Regie.ai focuses heavily on sequence writing and sales engagement with its Auto-Pilot feature. 11x is more focused on fully autonomous operation where the AI handles the entire prospecting workflow rather than assisting a human rep. The choice depends on whether your team wants AI to augment SDR work or to run it independently.

11x vs Lindy: Lindy is a general-purpose AI agent platform with sales workflow capabilities alongside email, meeting, and calendar automation. 11x is purpose-built for sales development specifically. If your primary need is outbound SDR automation at scale, 11x goes deeper. If you want an agent that handles sales plus broader professional workflow, Lindy covers more ground.

11x vs VAPI: VAPI is a voice AI infrastructure platform for developers building custom voice applications. 11x is an out-of-the-box sales solution. Teams that want to build custom voice sales workflows on top of infrastructure use VAPI. Teams that want a deployed voice SDR without building anything use Jordan.

Getting started

11x onboarding starts with a sales call to assess fit and configure the initial setup. The most important part of that process is ICP definition. Before your first call with 11x, document exactly who Alice should be reaching out to: industries, company size ranges, job titles, and the signals that indicate a prospect is in-market. The cleaner this is going in, the faster Alice produces quality output.

Once onboarded, start Alice in a monitored mode where you review a sample of outreach before expanding volume. This lets you catch any personalization errors, tone mismatches, or ICP drift in the research before they affect your domain reputation or prospect relationships at scale.

For Jordan, begin with inbound qualification before expanding to outbound calling. The use case of calling web form submissions quickly is well-tested and lower-risk than deploying voice AI to cold prospects who weren't expecting contact.

Plan for a calibration period of four to six weeks before drawing conclusions about performance. AI SDR output improves as the system learns which messaging, timing, and prospect signals correlate with positive responses in your specific market.

The bottom line

11x is a capable and ambitious platform that delivers on the promise of autonomous outbound if you give it a clear ICP and the time to calibrate. Alice is among the strongest email and LinkedIn SDR agents at the enterprise level, and Jordan's voice capability adds something genuinely rare among AI sales tools. The $1,500/month starting price and the absence of a trial period mean the entry decision requires real commitment, but for established sales teams with a working outbound motion, the unit economics are easy to justify if the alternative is hiring SDRs at traditional market rates.
