The verdict
For most lean founders running outbound, Apollo wins on day one: a free tier, a 59 USD entry plan, and database plus sequencing plus dialing in a single subscription you don't have to stitch together. That is the whole appeal of all-in-one when you are a team of one.
Dealfront wins the moment Europe and compliance enter the conversation. It is EU-hosted, GDPR-first, weighted to European contacts, and built around website visitor identification rather than bolt-on outreach. If your buyers are European, or your visitor traffic is the asset you most want to convert, Dealfront earns its higher starting price.
So it is less "which is better" and more "which problem is yours". Selling broadly and running outreach end to end, take Apollo. Selling into Europe with compliance and visitor de-anonymisation front of mind, take Dealfront.
