About Apollo.io

Apollo.io is a business-to-business sales platform that combines a contact database with the tools used to reach those contacts. Prospect records and outbound email sit in the same product, so a list built inside Apollo can be worked without exporting it to a separate sending tool first.

The platform covers lead generation and sales enablement. Email automation runs prospecting sequences, and contacts are engaged from one place rather than from a spreadsheet plus a separate mailbox. A Chrome extension brings the same records into the browser while working elsewhere. Website visitor identification names the companies behind site visits, at up to 100 companies a month.

Apollo integrates with Salesforce, HubSpot, Outreach, SalesLoft, Marketo and Sendgrid, and with more than 800 apps in total for automation. An API is available for data enrichment and other features, so records held elsewhere can be enriched without anyone opening the Apollo interface. The integration list is the main route for keeping Apollo and a CRM in step, since both hold records about the same companies and people.

Paid access is sized in credits, granted per seat. The free plan includes 900 credits per seat per year, released monthly. Basic costs $49 per seat per month billed annually and includes 30,000 credits per seat per year, granted upfront rather than in monthly instalments. Professional costs $79 per seat per month billed annually with 48,000 credits per seat per year, also granted upfront. Organization costs $119 per seat per month billed annually and requires a minimum of three seats. The practical difference between the tiers is therefore both how many credits arrive and how quickly they become available.

Apollo.io was founded in 2015 and reports use by more than 500,000 companies. The product is closed source and runs as a hosted service. Because the database and the sending tools share one subscription, the same seat that finds a contact is the seat that emails them, and credit allowances rather than separate licences set the ceiling on how much prospecting a team can do.
