## Business Model

[Apollo](/content/c/apollo/index.html) 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.

Additionally, it provides data enrichment, a rules engine, API integration, strong data security measures, and integrations with major CRM and marketing tools. [Apollo.io](/content/c/apollo/index.html) has a database of over 250 million contacts and 60 million companies.
