Companies listed as an Apollo.io integration

Source: Analysis of Linkedin bios of 28 companies that use Apollo Integrations Marketplace

I noticed these companies are primarily B2B sales and marketing service providers who help other businesses generate pipeline. They're not building products themselves, they're building revenue systems for their clients. Most are agencies or consultancies specializing in outbound prospecting, lead generation, sales development, and revenue operations. Several position themselves as implementation partners for specific platforms like HubSpot, Pipedrive, or Apollo itself.

These are predominantly small businesses in growth mode. My analysis shows 16 of the 22 companies have fewer than 50 employees, with most in the 2-10 range. Only three companies have any disclosed funding, and employee counts listed on LinkedIn profiles often don't match the ranges shown, suggesting very lean operations. The exceptions like SmartBug Media (180 employees, private equity backed) and Growth Era (205 employees) appear to be more established players, but they're outliers in this dataset.
