Captiwate's take

Apollo is already on our Sales Engagement Platforms list, but it deserves a mention here too — its 275M+ contact database is one of the top three lead generation databases in the market. For teams that want prospecting and outreach in one tool at an SMB price point, nothing else comes close. The key distinction from ZoomInfo: Apollo's UI is significantly better and the free plan is genuinely useful, not just a teaser.
