Our verdict on Waterfall

Waterfall is a B2B marketing intelligence service for go-to-market and revenue teams that need programmatic access to contact, company, and prospect data. Its API supports contact enrichment by email, LinkedIn, or name and domain; phone enrichment for mobile and direct-dial numbers; and company enrichment by domain, LinkedIn, or company name. Returned contact data can include verified email, phone numbers, job title, current company, location, and employment history, with real-time data freshness.

The product is designed around API workflows rather than a standalone visual application. Prospecting filters cover company, title, and location, while asynchronous enrichment workflows can trigger webhook callbacks when jobs are complete. Email verification adds deliverability status, and API key management plus usage reporting give teams visibility into access and consumption. Waterfall aggregates data from more than 30 vendors, making it suited to systems that need several enrichment paths behind one API.

Pricing is prepaid and usage-based, so it fits teams that prefer consumption-aligned spending over a fixed software subscription. The strongest use case is a revenue or marketing operation building enrichment into its own application, routing, or prospecting workflow. Teams that need native CRM synchronization, a browser-first interface, or a broader sales engagement environment should consider a different type of product. Waterfall is a focused choice for API-led enrichment, with its value concentrated in contact and company data retrieval, prospect discovery, verification, and event-driven processing.
