Valuation & Funding History

Business Model

Apollo found product-market fit giving SMB and startup sales teams access to a vertically integrated set of lead prospecting and outreach tools, and has since pushed deliberately upmarket, with enterprise accounts growing 400% over the past year alongside its self-serve SMB base.

Sales teams typically begin using Apollo by building an ideal customer profile (ICP) based on industry, company size, headcount, ARR, HQ location, and other data points.

Product

Apollo launched as a web scraping product with workflow tools layered on that helped sales teams quickly generate lists of leads and start emailing them immediately. Today, it is a go-to-market (GTM) platform that teams use to not just generate leads but prioritize outreach, create messages through generative AI, forecast revenue, and make calls.

Key features include a Chrome extension for easy access to contact details while browsing sites like LinkedIn, over 65 search filters, job change alerts, buying intent data, email sequences, a click-to-call dialer, and a task manager.

Additionally, it provides data enrichment, a rules engine, API integration, strong data security measures, and integrations with major CRM and marketing tools. Apollo.io has a database of over 250 million contacts and 60 million companies.
