Digital workers for go-to-market teams
HQ: San Francisco, CA, United States (originally London) | Founded: 2022 | Employees: ~150–250 (est.) | Stage: Series B — $50M led by a16z (Sept 2024) at ~$350M; $76M raised total | Website: https://11x.ai
11x builds AI sales workers. Instead of hiring and training human sales development reps, companies 'hire' 11x's digital workers: Alice prospects and runs outbound email, Mike handles voice outreach, and inbound reps respond to and qualify incoming interest. Each works from an integrated data cloud of hundreds of millions of contacts, personalizes outreach from public signals, manages replies and books meetings onto human calendars.
Hasan Sukkar founded 11x in London in 2022 and moved fast when large language models made conversational sales automation viable. Growth was steep — $0 to $2M ARR within six months — and in September 2024 the company closed a Benchmark-led $24M Series A and, two weeks later, a $50M Series B led by Andreessen Horowitz at a reported $350M valuation. The company has since relocated its headquarters to San Francisco and expanded from a single AI SDR into a roster of digital workers across outbound, voice and inbound.
The company operates at the center of both the excitement and the backlash around AI sales automation. Enthusiasts see pipeline generation as the highest-leverage, most repetitive job in go-to-market; critics point to a flood of AI-generated outreach that filters, spam systems and buyers are actively rejecting. 11x's answer is scale and coverage — a full digital team rather than a single tool — and enterprise controls over what its agents send.
11x turned the sales development rep into software. Its 'digital workers' — Alice for outbound prospecting and email, Mike for phone outreach — run end to end: building target lists from a data cloud of hundreds of millions of contacts, writing personalized sequences, replying to responses and booking meetings. The pitch is deliberately blunt: hire AI employees instead of humans.
Founder Hasan Sukkar, a University of Exeter graduate who started the company in London in 2022, hit a nerve during the AI SDR boom. The company went from zero to $2 million ARR in six months at 50% month-over-month growth, and in September 2024 pulled off the rarest funding trick in venture: a $24M Series A led by Benchmark and a $50M Series B led by Andreessen Horowitz at a reported ~$350M valuation — announced two weeks apart — for $76M raised in total.
The category 11x helped create is now brutal. AI SDRs proliferated through 2025–2026 (Artisan, AiSDR, Amplemarket, Salesforge and dozens more), buyers learned that unsupervised AI outreach burns domains and brands, and the market split between cheap automation and quality-first approaches. Independent reviews put 11x's Alice at roughly $5,000–15,000 per month — premium pricing that demands premium pipeline.
11x's bet is breadth: a full digital-worker roster (outbound, voice, inbound) rather than a single tool. If AI reps become the default way pipeline gets generated, the winner is whoever's agents actually book qualified meetings at scale. If they don't, this whole category becomes a spam footnote. The next two years decide which.
