We last covered Apollo.io in January 2024 as it crossed $100M ARR, doubling revenue from the year before with its vertically integrated outbound sales stack.

Here’s our Apollo.io update with key points via Sacra AI:

Sacra estimates that Apollo.io grew 40% year-over-year to reach $134M ARR in 2024, up from $96M ARR at the end of 2023, as it began layering in sales-assisted onboarding, analytics dashboards, and enterprise-facing features like Conversations to drive retention and ACV expansion.
With GTM teams increasingly consolidating enrichment, routing, messaging, and attribution into fewer tools, Apollo.io is positioning itself as the all-in-one default by launching bundled replacements for Clay (website visitor reveal), Clearbit (AI lead scoring), and Zapier (multi-branch workflows) into a single low-cost, vertically integrated platform.
As outbound shifts from volume-based cold outreach to behavior-triggered, warm engagement, Apollo.io has responded with a wave of launches including AI Signals, website tracking, score-based sequencing, and its Smart Meeting Suite—putting it in closer competition with 6sense, Gong, and ZoomInfo to own the full GTM feedback loop.
