Apollo.io, a pioneer in go-to-market solutions, has once again made headlines by securing the 119th rank in the prestigious Deloitte Technology Fast 500™ list for the year 2025. This recognition marks the second consecutive year the company has been acknowledged among the fastest-growing technology, media, telecommunications, life sciences, fintech, and energy tech sectors in North America. In 2024, Apollo was ranked 125th, highlighting a significant upward trajectory in its performance.

The Deloitte Technology Fast 500 rankings are determined by evaluating the percentage revenue growth over a three-year span, specifically from 2021 to 2024. Notably, Apollo.io recorded a remarkable 752% revenue growth during this period, signifying not only its robust business strategy but also an increasing adoption of its innovative go-to-market (GTM) platform.

Tim Zheng, Co-founder and CEO of Apollo.io, stated, "From our origins in B2B data to our transformation into a comprehensive agentic GTM platform, receiving recognition from Deloitte reflects our rapid progress and heightened influence in the marketplace."

Other notable functions include AI-powered lead scoring, which identifies high-intent buyers, and the 'Lookalikes' feature, enabling the discovery of new prospects who share similarities with a business's top customers. Apollo's inbound capabilities ensure that website visitors are identified, qualified, and routed efficiently, enhancing conversions with real-time insights.

In 2025, Apollo.io recorded an impressive $150 million in Annual Recurring Revenue (ARR), demonstrating a staggering 500% increase in the usage of its AI-driven platform.
