Each tier requires a demo and sales conversation for pricing. The platform also offers a free tier with 50 data credits per month, covering Company and People Search, Sales Alerts, a List Builder, and a Chrome Extension.

Feature Comparison

Teams prioritizing account-based advertising and deep predictive scoring will find 6sense's architecture oriented around that use case.

How Apollo Differs from 6sense

The most significant functional difference is execution depth. Apollo connects intent signals directly to the outreach tools needed to act on them: a prospect showing buying intent can move into a sequence, receive a call from the Power or Parallel Dialer, and have their record enriched, all without leaving Apollo.

This closed loop between signal and action is where Apollo's architecture differs from platforms built primarily around intelligence delivery.

Apollo's buying intent data includes 15K+ topics tied directly to contacts and accounts, available starting on the Basic plan. Teams can filter prospects by intent signal, prioritize outreach queues, and trigger automated sequences based on intent activity. This intent-to-action workflow is embedded in the same system used for day-to-day prospecting and engagement.

For inbound use cases, Apollo's website visitor identification, form enrichment, and inbound routing tools complement the outbound motion. A rep can identify anonymous visitors, enrich incomplete form submissions, and route qualified leads to the right owner, all within the same platform. Apollo's AI sales automation capabilities extend this further with AI-driven research, lead scoring, and automated follow-up sequences triggered on form submission.

According to Ramp's Sales Data Providers category data as of July 2026, Apollo is the fastest-growing vendor in the category, averaging +0.7 percentage points per month in adoption, outpacing all other vendors tracked. This growth reflects teams actively choosing Apollo as their primary sales data and engagement platform.

Customer outcomes reflect what the platform consolidation delivers in practice:

"We reduced the complexity of three tools into one.", Collin Stewart, CEO at Predictable Revenue

"Apollo enriches everything we have: contacts, leads, accounts...And we don't really have to touch it, it just works.", Mark Turner, VP of Revenue Operations at Built In
