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

Sacra estimates that Apollo.io hit $150M ARR at the end of May 2025, growing 40% YoY in 2004 to reach $134M ARR, up from $96M ARR at the end of 2023, giving it a ~10x forward revenue multiple off its August 2023 Series D led by Bain Capital Ventures (Merritt Hummer) which valued the company at $1.6B.
Most noticeably over the last 12 months, the contact data that Apollo weaponized to disrupt data brokers like Dun & Bradstreet (NYSE: DNB) and enterprise SaaS like Zoominfo (NASDAQ: GTM)—by making available via self-serve what previously required large up front payments—has itself gotten commodified by AI-powered scraping, with GTM teams shifting budget from volume-based cold outreach to signal & behavior-triggered, personalized engagement via AI sales research tools like Clay ( $30M ARR in 2024, growing 500% YoY).
Apollo has responded with a wave of launches including Scores & Signals ( Clay), Smart Meeting Suite ( Gong & Calendly) and Workflows ( Zapier), bundling together everything that GTM teams need with a lightweight CRM that positions Apollo as an all-in-one & system of record for SMBs, increases stickiness & drives seat expansion and makes it competitive against HubSpot (NYSE: HUBS).
