What’s driving Apollo’s growth

Revenue teams are moving away from fragmented tool stacks toward one place where data, automation, and intelligence work together.

That’s why we launched the industry’s first fully agentic, end‑to‑end GTM platform that helps teams find the right prospects, craft the right message, and take the right action, fast and at scale.

In 2025, Apollo reached $150 million in ARR, fueled by AI. We also saw a 500% increase in usage of our AI platform. G2’s Fall 2025 reports recognized Apollo across multiple sales categories. Today, Apollo powers the full sales cycle for millions of users, helping businesses of all sizes centralize and simplify their go‑to‑market.

"Recognition on Deloitte Technology’s Fast 500 reflects Apollo’s rapid growth and increasing leadership in the market,” said Tim Zheng, Co-founder and CEO at Apollo.

“This honor is a testament to the outstanding work of our employees and unwavering commitment to empower our millions of customers with simple, smart, and connected GTM that converts intent into revenue.”

Looking ahead

The future of GTM belongs to platforms that don’t just automate tasks but help teams drive outcomes. We’re building exactly that, while making it as easy as texting a friend.

We’re focused on making world‑class GTM accessible to every business, not just those with enterprise budgets.
