11x

11x is a vertically integrated GTM platform offering autonomous AI sales agents for outbound sales: lead research, multi-channel sequencing, voice calls and appointment booking in one tool.

Description

11x positions itself as an AI-native GTM platform with an AI SDR named Alice, who takes over complete outbound funnels: lead research, personalization, multi-channel sequencing across email, LinkedIn, SMS and voice, plus appointment booking through AI calls. Unlike pure enrichment or sequencing tools such as Clay or Apollo, 11x promises to cover the entire path from research to booking in a single tool, including CRM sync to HubSpot, Salesforce and Pipedrive, and a performance dashboard for the pipeline per AI rep.

According to the source, the quality of the results depends heavily on setup and prompt tuning. Voice calls using an AI voice touch on clear consent rules in Germany and the EU; a legal review of the cold calling practice is necessary before deployment. The offering is primarily optimized for the English-speaking market; German is possible but not the focus.

For Voyage Digital's own cold email workstream, 11x is mainly a market reference: an example of what a fully automated SDR stack can look like, not a concrete tool recommendation.

Assessment

AI features

Alice, the AI SDR An autonomous sales agent runs outreach across several channels at once.
AI voice calls An AI voice calls leads, qualifies them and books appointments.
Email sequencing Messages are personalised per lead from collected signals.
Lead enrichment Data is natively merged from multiple sources.
CRM synchronisation Connects to HubSpot, Salesforce and Pipedrive.

Suitable for

Outbound sales teams in B2B SaaS, agencies and scale ups who want to scale SDR capacity with AI agents
Companies with repeatable, clearly defined outbound motions and a clean ideal customer profile
As a reference point for building your own, partially automated outbound workflows
Less suitable for Less suited to complex enterprise sales processes; according to the source, human sales remains superior there

Limitations and notes

Pricing model Enterprise pricing on request, typically in the range of several thousand euros per month.
Variable result quality Setup and prompt tuning largely determine the outcome.
Voice AI and consent Germany and the EU have clear consent rules for cold calling by AI voice. A legal review before deployment is necessary.
Role in the sales process Before rollout, it should be clarified whether the AI is meant to replace or augment human SDRs.
Language German is possible, but the offering is primarily oriented toward the English-speaking market.

Quick start

Open 11x.ai and request a demo.
In the discovery call with the provider's team, go through use cases and the ideal customer profile.
Train Alice with company-specific context, load the ICP list and start the first campaign.

Tips

Start with a clearly defined ideal customer profile, otherwise conversion stays weak.
Use voice calls only with clean opt-in logic to minimise legal risk.
Plan a phase of human oversight before fully autonomous use.
Run A/B tests between human SDR and Alice for a clean ROI measurement.
Set up the connection to the existing CRM workflow early.

Access

Access to 11x runs through the provider page at 11x.ai. Since the platform works with enterprise pricing, the path leads through a demo call with the sales team rather than self-service registration.
