Our take
Today, businesses are struggling to make their go-to-market (GTM) strategies simple, connected, and intelligent. In most organizations, sales and marketing teams juggle a maze of disconnected tools just to reach the right customers and close deals. This results in a lot of manual work and missed opportunities. So Apollo.io is stepping in to fill the gap and redefine how modern revenue teams operate by unifying the entire GTM process under one AI-powered roof.
It's trusted by millions of users and over 550,000 companies, including fast-growing startups to established enterprises like Autodesk and Cyera. Apollo's strength lies in combining B2B data with advanced AI to automate everything from prospecting and outreach to deal management and data enrichment. And its new "Agentic End-to-End GTM Platform" takes this one step further by introducing AI agents that act as co-pilots, working alongside sales and marketing teams to research leads, personalize outreach, and streamline workflows.
Recently, the company surpassed $100M in annual recurring revenue, expanding its leadership team with veterans from Zendesk, Intercom, Box, and Miro, and even launched a major product overhaul centered on its new "Vibe GTM" approach. And with its Agentic platform now bringing AI into every stage of the customer journey, Apollo sure is positioning itself to define the next era of AI-powered sales.
