Top 5 6Sense Alternatives (2025)

We tested the top 6sense alternatives

Only one turned signals into scheduled meetings.

Why we staged the teardown

6sense makes a strong pitch: fuse buyer intent, predict readiness, and orchestrate outreach across your tech stack.
It’s a compelling vision, especially for RevOps teams buried under enrichment tools, dashboards, and disconnected workflows.

But orchestration ≠ execution.

Most platforms tell your team what to do. 11x is the only one that does it for you.

So we ran a teardown of the leading 6sense alternatives—including Clay, Cognism, ZoomInfo, Clearbit, and 11x—to answer the only question that matters:

Which one turns go-to-market signals into actual booked meetings?

Because here’s the real problem: most GTM platforms were built for “alignment,” not outcomes. They promise smarter targeting, prettier workflows, and more precise segmentation, but still expect humans to carry the weight. Writing the messages. Handling replies. Booking the calls.

And that’s exactly where 11x is different.

‍

Platforms Tested

• 11x (Alice + Julian): Digital Workers that autonomously execute outbound + inbound across all channels
• 6sense: Predictive scoring, account orchestration, and ABM campaign automation
• Clay: Multisource enrichment and AI-powered outbound builder
• Cognism: Highly accurate B2B contact data, especially for phone numbers
• ZoomInfo: Massive intent + contact database with engagement tooling
• Clearbit: Real-time B2B enrichment and lightweight segmentation

‍

What We Measured

• Lever: Real-world impact
• Speed-to-action: Can it respond instantly to demo forms, job changes, or buying intent?
• Multichannel fluency: Does it natively operate across email, phone, SMS, LinkedIn, WhatsApp?
• Pipeline output: Are signals converted into actual conversations and booked meetings?
• Setup drag: Can GTM teams activate it in hours—not weeks of configuration?
• Maintenance load: Does it self-improve, or require constant playbook babysitting?
• Security readiness: Is it enterprise-compliant and safe to deploy in sensitive environments?

‍

11x replaced workflows with results

While others unified dashboards, 11x deployed agents. Alice and Julian didn’t just see signals, they acted.

Inside a week with Alice & Julian (11x)

Day-zero deployment

14:00 – 15,000-row CSV uploaded
14:02 – Alice dedupes against HubSpot, enriches with 17+ live signals
14:05 – Domain health checks + warm-up begin
14:06 – First batch of personalized outreach launches via email, LinkedIn, SMS

Inbound response in 17 seconds

03:17 – A VP of Marketing fills out a demo form
03:17:17 – Julian calls, qualifies, handles objections, books the meeting
03:18 – Calendar invite sent, CRM updated, Slack alert fired

Smart sequencing in real time

1. Alice detects email decay, pivots to WhatsApp
2. Picks up new funding signal, rewrites messaging mid-cadence
3. Books meeting with a previously cold prospect—autonomously

‍

Where 6sense dominates in data, and where it still trails 11x

6sense is best-in-class at intent orchestration. It scores accounts, models buyer readiness, maps stakeholders, and syncs beautifully with Salesforce and Marketo. The platform even lets you launch ads and email workflows from a central canvas, giving RevOps full visibility into account engagement and campaign lift.

But when we put it head-to-head with 11x, three critical gaps stood out:

6sense is a powerhouse for GTM intelligence, but it’s still a copilot, not a closer. 11x deploys digital workers who don’t just inform your team, they replace entire slices of GTM motion, turning every signal into a scheduled meeting, automatically.

Where the other platforms fell short

2. Clay

Strengths

4. ZoomInfo

Strengths
