Apollo fits high-volume prospecting teams. Clean fits teams where deal quality, timing and relevance matter more than the size of the list.

| Deal type | High-volume, transactional | Considered B2B deals |

Apollo wins on raw coverage and price-per-contact. If you need a large prospecting database, built-in sequencing, and the ability to run high volume across a wide market, Apollo's data and tooling are hard to beat at its price point.
Clean wins when each conversation is valuable and the market is narrow. It ranks companies against your ICP on the records of what they're doing now, names who to contact and shows who can introduce you, so reps work fewer, better-fit buyers.
Apollo is a contact database with email sequencing. Clean starts from what companies actually do: it finds companies with a reason to buy, ranks them against your ICP, names who to contact and shows who can introduce you.
Not scraped contact lists. Clean works from dated records of what companies do (loans, permits, customs shipments, contract awards), its own datasets and licensed company data, and it keeps the source behind every record so you can check it. The people at each company come from licensed data providers, so Clean names them without any integration connected. Work emails and phone numbers come from licensed contact-data providers and are verified before they show. If your team connects LinkedIn, Clean also searches LinkedIn and reads profiles through it, read-only, to find and confirm the right people and show who can introduce you.
Clean is an alternative for teams that want fit and timing before reach, not a like-for-like database swap. Apollo gives you contacts at scale; Clean decides which companies are worth working and shows why.
Yes. You can keep Apollo for breadth of contact data and use Clean to choose which companies to work, ranked against your ICP with the records behind each one.
Choose Apollo when you need high-volume coverage of a broad market, you already know your target titles, and your outbound can tolerate more sends. Apollo's database size and sequencing throughput fit that job better than a short, ranked list.
No. Clean never sends, posts or replies. It finds and ranks the prospects, and your team reaches out from its own tools.
