Automating Waterfall Enrichment with WaterFull: A Practical Guide for B2B GTM Teams

For B2B go-to-market (GTM) teams, the difference between a qualified lead and a missed opportunity often comes down to data. Job titles, company size, phone numbers—small gaps in your lead or account data can create big inefficiencies across sales and marketing.

To address this, more teams are turning to Waterfall Enrichment—a method of sequentially enriching records using multiple data providers to maximize completeness and accuracy. It’s a concept that’s gained traction among revenue operations and marketing leaders looking to boost funnel performance.

But implementing it well can be messy.

WaterFull is a tool built to automate this process. Instead of manually integrating and managing multiple enrichment vendors, WaterFull runs the waterfall for you. This article breaks down what Waterfall Enrichment is, why it matters for GTM teams, and how automation tools like WaterFull make it more accessible.

What Is Waterfall Enrichment?

Waterfall Enrichment is a process where contact or account records are passed through multiple enrichment providers in sequence. If one vendor can’t return complete data, the next is queried, and so on, until the best-available data is captured.

For example:

• Vendor A (like Clearbit) returns job title and company domain.
• Vendor B (like Apollo) adds a direct dial and LinkedIn URL.
• Vendor C (a regional specialist or human researcher) fills in anything still missing.

Instead of settling for what one vendor returns—or building complex enrichment flows manually—teams use Waterfall Enrichment to improve data coverage and accuracy.

Why It Matters for B2B GTM Teams

High-quality data is foundational to GTM execution. It impacts:

• Lead scoring – Incomplete data limits your ability to assess fit.
• Routing – SDRs may be assigned low-priority or irrelevant leads.
• Personalization – Marketing campaigns and outbound messages fall flat without context.
• Sales efficiency – Reps waste time chasing unqualified or unreachable contacts.

Given the speed and scale of modern GTM, data enrichment isn’t optional. But relying on a single enrichment provider often leads to patchy data. That’s where the waterfall approach provides real value—especially when automated.

How WaterFull Fits In

WaterFull is a tool that operationalizes Waterfall Enrichment. Instead of building complex workflows across tools like Zapier, Clearbit, Apollo, and your CRM, WaterFull connects everything under one roof and handles the logic automatically.

Here’s a high-level look at how it works:

1. Trigger Points

WaterFull starts enriching when a new record is created—via form fill, upload, CRM integration, or a sales tool.

2. Sequenced Enrichment

Records are enriched by multiple vendors in a pre-defined order. If one vendor doesn’t return key fields, the next is triggered.

3. Data Merging

Instead of overwriting or duplicating fields, WaterFull merges returned values based on source confidence and completeness.

4. Return to CRM/MAP

Once complete, enriched data is pushed back into systems like Salesforce, HubSpot, or Marketo—ready for routing, scoring, and campaign workflows.

Key Use Cases

WaterFull’s automated waterfall enrichment supports several practical scenarios across the GTM funnel:

Inbound Lead Enrichment

Most forms only ask for a name and email. With waterfall enrichment, these records are automatically filled out with company, role, location, and more—allowing faster routing and response.

Outbound Prospecting

When building outbound lists, especially for niche or international markets, no single vendor offers complete coverage. WaterFull combines strengths from multiple sources to improve reach and accuracy.

ABM and Buying Committee Mapping

Strategic GTM teams often need to engage multiple personas within the same account. WaterFull helps identify and enrich these profiles across job functions and seniority levels.

CRM Hygiene and Backfill

Stale or incomplete records limit segmentation and reporting. WaterFull can re-enrich existing data to keep CRMs clean and usable.

Attribution and Reporting

Enriching historical leads with missing job titles, industries, or channels helps marketing and RevOps teams better understand funnel performance.

Implementation Considerations

Automating waterfall enrichment sounds ideal—but it’s not without its complexities. Here are some things to keep in mind:

Data Quality vs. Cost

More vendors in your waterfall usually means higher match rates—but also higher costs. WaterFull helps manage this by prioritizing vendors based on accuracy, cost, or use case.

Compliance

Ensure your enrichment tools and vendors comply with privacy regulations (like GDPR and CCPA). WaterFull includes source tagging and audit trails to support compliance reviews.

Workflow Integration

Waterfall enrichment is only valuable if it integrates into your broader GTM systems—like lead scoring models, routing rules, or campaign segmentation. WaterFull is built with native integrations for common GTM tools.

Overwriting Logic

One of the biggest risks in enrichment is overwriting verified data with lower-quality data. WaterFull lets teams control which fields to enrich, when to enrich them, and from which source.

Why Teams Choose Automation Over Manual Workflows

Some GTM teams try to build their own waterfall enrichment logic using custom scripts, APIs, or iPaaS tools like Zapier. While possible, these setups often require:

• Constant monitoring of vendor match rates
• Manual handling of merge logic and fallbacks
• Updates to workflows as business needs evolve

WaterFull abstracts away that complexity. Teams still control which vendors are used and how logic is applied, but the tool handles the orchestration, enrichment, and data hygiene in the background.

For most teams, this trade-off—more control with less maintenance—is worth it.

Final Thoughts

Waterfall Enrichment is becoming a best practice for B2B teams that rely on accurate, up-to-date contact and account data to power their GTM motion. But doing it right requires more than just stacking vendors—it needs orchestration, logic, and compliance.

That’s where tools like WaterFull offer real utility. They don’t change the strategy. They just make it easier to execute.

For RevOps leaders, marketers, and sales teams looking to scale without compromising on data quality, automated enrichment is quickly moving from “nice to have” to table stakes.
