Best Data Enrichment Tools in 2026
Enrichment is the difference between a list of companies and a list of reachable, qualified people with context. The modern setup is a waterfall: several providers tried in sequence, AI research on top, scraping underneath for what no database has.
Our take
Clay is the table everything runs through - waterfalls, AI columns, scoring. Oxygen is the newer bet we're building on: enrichment, signals and sequences in one AI-native workspace instead of five subscriptions. Apify feeds both with scraped data no provider sells.
🥇ClayIn our stack
The spreadsheet-with-superpowers where enrichment waterfalls, AI research columns and lead scoring live. Steep learning curve, unmatched flexibility - it's where our client lists are built.
Best for: Waterfall enrichment and AI-scored list building
🥈OxygenIn our stack
AI-native GTM workspace - records, enrichment, signals and sequences in one place instead of a stack of subscriptions. Younger ecosystem, moving fast; we run it alongside Clay.
Best for: Teams consolidating the GTM stack into one workspace
🥉ApifyIn our stack
Scraping infrastructure with thousands of ready-made actors - the data no enrichment provider sells (directories, job boards, reviews) enters the pipeline here.
Best for: Custom data sources feeding your enrichment
FAQ
What is waterfall enrichment?
Trying multiple data providers in sequence for each record - if provider A misses the email, ask B, then C. It's the standard way to lift coverage without paying every provider for every row.
Do I need Clay if I have a CRM?
They do different jobs. The CRM stores relationships; Clay builds and enriches the lists that feed it. Most teams push finished, scored lists from Clay into the CRM or the sequencer.
How much does enrichment cost per lead?
With a waterfall and sane scoping, fully-enriched B2B contacts (verified email + firmographics + context) typically land between $0.10 and $0.40 each, driven mostly by which providers your waterfall hits.

Tools don't close deals. Systems do.
We wire these into one running GTM machine - signals, enrichment, sequences and a client portal on top. You keep the stack; we make it work as one.
