The Best Waterfall Enrichment Tools (2026)
pipe0, FullEnrich, BetterContact, and Clay compared: sources, billing models, verification, and where each waterfall tool fits.
Waterfall enrichment tools query data providers in order and stop at the first hit. If that concept is new to you, start with What is waterfall enrichment?
In this blog post, we compare the waterfall tools teams actually shortlist in 2026. pipe0 is our product, so read our take on it with that in mind.

pipe0
pipe0 runs waterfalls as part of a larger enrichment engine: 100+ enrichments and searches, with waterfall pipes for work emails, personal emails, phone numbers, and company data.
A few things are different about our approach.
We curate providers instead of chaining as many as possible. A provider only joins a waterfall when it adds unique coverage, and we negotiate custom rates with providers that have strong datasets. pipe0 is also the only waterfall allowed to serve Amplemarket data. In our pricing comparisons this comes out to roughly 7x as cost effective as traditional waterfall providers; run your own list and check.
You get a full waterfall UI: see the providers in every chain, reorder them, remove them, or bring your own API keys. And the waterfalls run everywhere the engine runs: in sheets that hold up to 2M rows, through the API, or driven by AI agents over MCP.
Billing is on success only. A provider that returns nothing bills nothing.
FullEnrich
FullEnrich is a focused waterfall product for emails and mobile numbers. It aggregates 20+ vendors, advertises a find rate above 80%, and puts extra work into phone numbers: mobile first, landlines free, with ownership validation for US and Canada numbers.
Pricing starts at $29/mo and there are 50 free leads to test with. If your entire problem is "get me emails and mobiles for this list" and you want the smallest possible tool, FullEnrich is a fair pick. There is no table product or workflow layer around it.

BetterContact
BetterContact also aggregates 20+ providers for emails and mobile numbers. Its pitch is verification: four validation layers, and you are only charged when the data is valid. An algorithm picks the provider order per contact.
It runs inside other tools too, including Clay. Like FullEnrich it is a single-purpose product: the waterfall is the whole thing, and your lists live somewhere else.
Clay
Clay is not a waterfall tool so much as a workflow platform with waterfalls inside. You build tables, and enrichment columns can cascade across what Clay describes as 200+ vendors.
If you want the full platform around the waterfall, Clay is the established option, with the largest template community in the category. The waterfall itself is not separable from the platform: there is no public API to run one from your own code. We compare the two in detail in pipe0 vs Clay.
Which one should you pick?
Run the same 200 rows through your finalists and count three things: found emails, valid phones, and cost per found record. Vendor find-rate claims do not survive contact with a real list, ours included.
As a rough guide: FullEnrich or BetterContact if you want a small single-purpose tool. Clay if you want the whole workflow platform and its ecosystem. pipe0 if you want curated waterfalls plus the sheet, the API, and the agents on one engine.
