Where each tool wins.
Where Apollo wins
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.
Where Clean wins
Clean wins when each conversation is valuable and the market is narrow. It ranks accounts by fit and timing, maps warm paths through your real network, and grounds every send in your knowledge so reps work fewer, better-fit buyers.
By the numbers
Clean profiles every lead against 75 buying signals across 8 categories for under a dollar, then ranks accounts S through C.
Common questions.
Does Clean use scraped lists?
Clean is designed around warm relationship paths, public buying signals, and company-specific context rather than generic cold CSVs.
Is Clean an Apollo alternative?
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 contacts are worth working and grounds the outreach. Teams chasing fewer, higher-quality conversations switch to Clean.
Can I use Apollo and Clean together?
Yes. Some teams keep Apollo for breadth of contact data and use Clean to choose which accounts to actually work, rank them by fit, and write grounded messages for the highest-priority buyers. Apollo supplies reach; Clean supplies judgment.
When should I choose Apollo over Clean?
Choose Apollo when you need high-volume coverage of a broad market, you already know your target titles, and your motion tolerates more sends. Apollo's database size and sequencing throughput fit that job better than a low-volume system.
Does Clean protect deliverability better than high-volume sequencing?
By design, yes. Clean constrains outbound to high-fit, warm-path buyers with grounded messages instead of large templated sends, which is the main driver of domain reputation damage. Lower volume with stronger relevance is the safer posture for considered deals.
