11x provides AI digital workers for sales development, featuring Alice the AI SDR for autonomous outbound email prospecting and Julian the AI Phone Agent for intelligent voice conversations. The platform handles end-to-end sales development workflows including prospect identification, research, personalized outreach, follow-ups, and meeting scheduling — operating 24/7 to generate qualified pipeline at a fraction of the cost of human SDR teams.
11x offers AI digital workers that replace human SDRs for enterprise sales teams. Alice autonomously handles outbound email and LinkedIn prospecting, while Julian manages phone-based conversations. The platform identifies prospects from a 200M+ contact database, researches them using real-time signals, writes personalized outreach, and books meetings on your team's calendar — all without human intervention, 24/7.
11x has built a new category of enterprise software: AI digital workers that fully replace traditional sales development representatives. Rather than offering another automation tool that requires human operators, 11x deploys autonomous AI agents — Alice for written outbound and Julian for phone-based conversations — that independently execute the entire SDR workflow from prospect identification through meeting booking.
Alice, the flagship AI SDR, taps into a database of over 200 million B2B contacts to identify prospects matching your Ideal Customer Profile. She researches each prospect using real-time signals including company news, job changes, funding events, and technology stack data, then crafts genuinely personalized outreach emails that go far beyond first-name token insertion. Alice manages multi-step email sequences, handles follow-ups, coordinates LinkedIn outreach, and books meetings directly on your sales team's calendars — all without human intervention.
Julian, the AI Phone Agent, extends 11x's coverage to voice channels. Julian handles both inbound and outbound phone calls with human-like conversational ability, qualifying leads through natural dialogue and transferring high-intent prospects to human reps. With multilingual capabilities, Julian enables global teams to scale phone-based qualification without hiring region-specific staff.
The platform integrates natively with Salesforce, HubSpot, and other major CRMs, automatically logging all activities and syncing prospect data. Enterprise-grade security including SOC 2 Type II compliance, GDPR-compliant data processing, and encryption at rest and in transit ensures the platform meets the requirements of large revenue organizations.
Customers typically report 150–200% ROI in the first year, with Alice generating pipeline equivalent to multiple human SDRs at roughly half the cost. Companies like high-growth B2B SaaS firms, staffing agencies running high-volume outreach, and enterprise teams expanding into new markets have deployed 11x to systematically scale outbound pipeline without proportionally scaling headcount.
Founded in 2022 by Hasan Sukkar and headquartered in San Francisco with offices in London, 11x has raised over $74 million from investors including Andreessen Horowitz, Benchmark, and SV Angel, reflecting strong market confidence in the AI digital worker category.

11x AI works well for high-volume outbound teams with clearly defined ICPs but struggles to deliver consistent value for companies with niche markets or complex sales motions. Users praise Alice's ability to generate pipeline autonomously around the clock and the cost savings versus human SDR teams, with strong customer testimonials citing $1M+ pipeline generated in the first quarter. However, Reddit reviews and G2 feedback reveal a polarized experience: satisfied enterprise customers see meaningful ROI, while others report poorly targeted prospects, generic-sounding personalization, and frustration with opaque pricing and rigid annual contracts. Julian (AI Phone Agent) adds valuable multichannel coverage but is less proven. Overall, 11x is best suited for well-funded B2B companies with large addressable markets and straightforward ICPs that can justify the $50K+ annual investment.
Alice independently identifies and qualifies prospects from third-party databases containing over 200 million B2B contacts, matching them against your defined Ideal Customer Profile using firmographic, technographic, and intent signals. She researches each prospect using real-time data sources — company news, job changes, funding rounds, technology stack changes — then crafts genuinely personalized outreach emails that reference specific, relevant details rather than relying on generic templates with first-name tokens.
Julian handles inbound and outbound phone calls with human-like reasoning and natural conversational flow. For inbound calls, Julian qualifies leads through dynamic dialogue, asks relevant discovery questions, handles common objections, and routes high-intent prospects to human sales reps in real time. For outbound, Julian makes cold calls at scale with multilingual capabilities, enabling global teams to cover phone-based outreach without hiring region-specific staff.
11x coordinates engagement across email, LinkedIn, and phone channels from a single platform, ensuring consistent messaging and optimal sequencing across touchpoints. Alice manages email sequences and LinkedIn connection requests while Julian covers the phone channel, with all activities logged centrally and visible in your CRM. This eliminates the need to stitch together separate tools for each channel and ensures prospects receive a cohesive experience across every interaction.
Unlike template-driven competitors that insert first-name tokens into pre-written emails, 11x generates unique outreach content for each prospect based on deep research. Alice analyzes company news, recent job changes, LinkedIn activity, technology stack, funding history, and industry trends to craft messages that demonstrate genuine relevance. This approach consistently achieves higher response rates than traditional mail-merge personalization while operating at volumes that would be impossible for human SDRs to match.
The platform's machine learning engine analyzes engagement data across all outreach — open rates, reply rates, meeting conversion rates, and sentiment signals — to continuously refine messaging, subject lines, send timing, and prospect targeting. Unlike manual A/B testing that requires human analysis and iteration, Alice's optimization loops run automatically, compounding performance improvements over time without requiring ongoing intervention from your sales team.
Seamless integration with Salesforce, HubSpot, and other major CRMs ensures every prospect interaction, email sent, reply received, and meeting booked is automatically logged and attributed in your pipeline. Real-time bi-directional syncing keeps your CRM as the single source of truth while giving Alice access to existing account data and deal context. This eliminates manual data entry and provides RevOps teams with accurate attribution for AI-generated pipeline.
Alice supports outreach in multiple languages, enabling global prospecting campaigns without hiring region-specific SDRs. Combined with Julian's multilingual phone capabilities, 11x allows companies expanding into new geographic markets to launch localized outreach campaigns that respect cultural communication norms and language preferences, significantly reducing the cost and time-to-market for international expansion.
Alice handles the entire meeting booking process including calendar coordination, time zone management, confirmation emails, and reminder sequences. When a prospect expresses interest, Alice proposes available times from your connected calendar (Google Calendar or Outlook), confirms the booking, sends calendar invites, and follows up with reminders to minimize no-show rates. This eliminates the back-and-forth scheduling friction that often causes interested prospects to go cold.
