> A list of three waterfall data enrichment providers that you can trust. From traditional waterfall to front-loaded waterfalls. Find the provider that fits your stack.
Waterfall enrichment has become a household practice in many organizations.
It describes the practice of chaining multiple B2B data vendors together to
increase coverage.
We've previously written about
[what waterfall enrichment is](/blog/what-is-waterfall-enrichment) in detail.
In this blog post, we want to introduce you to two flavors of waterfall
enrichment and compare Surfe, FullEnrich, and pipe0.
## Two flavors of waterfall enrichment worth knowing [#two-flavors-of-waterfall-enrichment-worth-knowing]
### Embedded waterfalls [#embedded-waterfalls]
Embedded waterfall providers manage the full waterfall for you. You hand them
your data and they either return a result or they don't.
If a result is returned, you are charged a flat fee that typically sits
between 25¢ and 100¢ per mobile number and 9¢ and 30¢ per work email.
This charge is typically static regardless of which provider returns a result.
Providers that offer this are FullEnrich, Surfe, or BetterContact.
### Front-loaded waterfalls [#front-loaded-waterfalls]
The flat charge of embedded waterfall providers can be cost inhibiting for
you. You will pay the same for data that is easily resolvable with cheap
providers as you'll pay for data that is hard to resolve.
Embedded waterfall providers trade coverage for cost-efficiency.
Front-loaded waterfalls, in contrast, charge a variable fee for the provider
that actually resolves your data.
When designed correctly, they will place a fast, cheap provider in front of an
embedded waterfall provider.
With this design you pay less for data that is easy to resolve and more for
data that is hard to resolve.
Be aware that this will cost a few points in accuracy.
## Three waterfall providers worth your attention [#three-waterfall-providers-worth-your-attention]
### Pipe0 – high coverage & accuracy at low prices [#pipe0--high-coverage--accuracy-at-low-prices]
The first provider on this list is [pipe0](https://pipe0.com).
Pipe0 is the only front-loaded waterfall provider on this list. It offers an
API, MCP, and UI for data enrichment.
With pipe0, you pay a different rate depending on which provider resolves a
request. This averages around 14¢ per mobile number and 4¢ per work email.
These are the lowest rates on this list. Additionally, pipe0 offers dedicated
high-volume pricing to make data enrichment cost-effective when you need to
enrich millions of records.
Pipe0's API is also the only API on this list that allows you to change the
list and order of providers in the waterfall on demand.
These attributes make pipe0 stand out among the providers on this list.
### FullEnrich – high coverage at higher prices [#fullenrich--high-coverage-at-higher-prices]
[FullEnrich](https://fullenrich.com) is a traditional waterfall provider.
According to their marketing documentation, they combine 20+ providers for
their waterfalls and claim the highest match rates in the industry.
We cannot confirm this. In our benchmarks, both Surfe and pipe0 consistently
beat FullEnrich on both accuracy and coverage.
However, FullEnrich is still an established provider that provides match rates
that are far above average when compared to other providers.
FullEnrich is on the pricier side, charging a flat rate of roughly 55¢ per
enriched phone number and 5.5¢ per work email.
In addition to enrichment, FullEnrich also offers an endpoint for reverse
email lookup and search.
### Surfe – high coverage & high accuracy [#surfe--high-coverage--high-accuracy]
[Surfe](https://surfe.com) is a newer enrichment provider based in France. In
our testing, Surfe had excellent coverage and scored high on accuracy.
On average, a work email enrichment costs roughly 9¢, while a mobile
enrichment costs roughly 24¢.
Surfe is another traditional waterfall provider, charging a fixed fee per
enrichment.

Of the three providers compared here, pipe0 has the lowest average rates at around 14 cents per mobile number and 4 cents per work email.
