The short answer
Clay, Apollo, and Clean are not substitutes; they win different jobs. Clay is an enrichment workflow canvas for ops engineers. Apollo is a prospecting database and sequencer for volume. Clean finds companies with a reason to buy from public records, ranks them against your ICP and names who to contact. Pick by your bottleneck: data assembly (Clay), contact access (Apollo), or knowing who to work and why (Clean).
Use Clay when you need custom enrichment workflows. Use Apollo when you need a broad contact database and sequencing. Use Clean when you need the companies with a reason to buy found and ranked for you.
Clay is strongest for ops engineers who want to assemble data sources, enrichment steps, and custom research workflows. It is flexible infrastructure.
Apollo is strongest when the team needs a large contact pool, prospect filters, enrichment, and sequencing in one sales prospecting platform.
Clean is strongest when the team needs judgment before activity: companies found from dated records, ranked against your ICP, with who to contact and who can introduce you.
Choose based on the bottleneck. If the bottleneck is data assembly, Clay may fit. If it is contact access, Apollo may fit. If it is knowing who to work and why they should respond, evaluate Clean.
Clay vs Apollo vs Clean by job-to-be-done
| Clay | Apollo | Clean | |
|---|---|---|---|
| Category | Enrichment workflow canvas | Prospecting database and sequencer | Buyers ranked from public records |
| Best for | Ops engineers | High-volume prospecting | Considered B2B deals |
| Starting point | Data sources you wire up | Contact filters | Your ICP and dated records of what companies do |
| Prioritization | You design it | Filters | Built in, against your ICP |
| Outreach | Bring your own downstream | Built-in sequences | Your team sends; Clean never does |
Clay wins when the bottleneck is data assembly and you have an ops engineer. Nothing matches its flexibility for wiring many sources into custom enrichment tables.
Apollo wins when the bottleneck is contact access. A large database plus built-in sequencing is the fastest way to reach a broad market at volume.
Clean wins when the bottleneck is judgment: knowing which companies are worth working, why now, and who to contact. It ranks them against your ICP, shows the records behind each one and shows who can introduce you.
Clay is a flexible enrichment and workflow tool that an ops engineer builds on. Clean does the work itself: it finds buyers from public records, ranks them against your ICP, names who to contact, and shows who can introduce you.
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.
No. AI SDR tools automate outreach volume. Clean doesn't send anything. It finds a short list of companies with a reason to buy and shows the records behind each one.
Pick by bottleneck. If you need to assemble and transform data from many sources and have an ops engineer, pick Clay. If you need broad contact coverage and sequencing, pick Apollo. If you need to know which companies are worth working and why, pick Clean.
Yes. You can keep Clay or Apollo for data and reach and use Clean to decide which companies to work, ranked against your ICP with the records behind each one.
It depends on your stack. Clean replaces the research you would otherwise stitch together across tools: finding the companies, ranking them and naming who to contact. Book a demo and we'll walk through what it replaces for you.
