Apollo.io, an integrated business-to-business (B2B) sales intelligence and engagement platform, said on Friday that it has closed a $110 million funding round led by Sequoia Capital.

The round also saw participation from existing investors Tribe Capital, Nexus Venture Partners, and NewView Capital.

The platform plans to use the funds to accelerate its product-led growth. It also plans to increase its investment in product and engineering by nearly 300% to continue to build the best platform in its category. Apollo.io has raised over $150 million to date.

The funding comes on the heels of a period of strong growth for Apollo.io. Its annual recurring revenue (ARR) has nearly tripled in the past 12 months, the company said in a statement. Since announcing its Series B round of funding three months ago, Apollo.io expanded its paid customer base by nearly 60% to over 15,000 paying customers.

“This funding will enable us to hire the very best people in the industry, continue to build and market our category-leading sales intelligence and engagement platform, and accelerate our growth with investments in marketing and sales,” said Tim Zheng, cofounder and CEO, Apollo.io.

The platform claims to help over one million professionals, across 160,000 companies, automate their sales processes and 10X their revenue.

“Apollo.io simplifies the convoluted and manual processes of sales prospecting—ultimately, making smart, data-driven GTM simple and accessible to all,” said Sonya Huang, Partner at Sequoia.

“Tim and the Apollo team have built a product-led tool that is beloved by thousands of customers. We couldn’t be more excited to partner with Apollo on their journey to help every company reach its full potential,” Huang added.
