Apollo.io Crosses $150M in ARR, Fueled by AI 🚀
Today, I’m incredibly proud to announce that Apollo has officially hit $150 million in annual recurring revenue (ARR).
It's a big milestone — not just because of the number, but because of what it represents.
A few years ago, Apollo was at a crossroads. As I shared at SaaStr, our growth had stalled, and we had to make some tough calls. We got focused and we rebuilt the product, our go-to-market strategy, and our fundamental understanding of how businesses connect.
Today, Apollo powers millions of go-to-market professionals around the world, solving real problems in ways others haven't imagined. And we’re growing faster than ever thanks to our next big unlock: AI.
Our recent AI platform metrics tell a powerful story:
-
500% year-over-year growth with over 50,000 weekly active users
-
47 million targeted prospecting actions in 2025 alone, transforming how sales teams discover and engage potential customers
-
Sales teams using Apollo's AI Research Agent book 46% more meetings, driving a 35% increase in bookings, proving AI's power in sales engagement
But the impact isn’t just in the metrics. It’s in the real stories our customers tell us about overcoming their own crossroads moments.
Take Smartling, a language translation company that was drowning in manual prospecting. Using Apollo's AI Research Agent, Smartling has unlocked a 10x productivity surge that seemed impossible just months ago. Their reps are now focused on high-value conversations, sending hyper-personalized emails and closing deals they couldn’t before.
That’s what we’re building toward: helping teams of all sizes win more with smarter systems.
This achievement belongs to our incredible team, our passionate customers, and an unwavering belief that there's always a better way to grow.
We're just getting started. And trust me, the next chapter will be even better.
Onward.
