What it is
A data waterfall, also called cascade enrichment, is a method for enriching a contact or company record by querying multiple data providers in a fixed sequence rather than relying on a single source. Provider A is tried first; whatever it cannot verify, an email, a direct dial, a job title, passes to provider B; whatever B cannot resolve passes to provider C, and so on, until a verified data point is found or the list of sources is exhausted. The record only moves on to the next provider in the chain if the current one falls short.
The technique comes from sales-ops and RevOps tooling, where teams stitch together several enrichment vendors, a contact database, a phone-verification tool, a professional-network lookup, because no single vendor covers every contact well. Recruitment BD faces the identical problem: a hiring decision-maker's email might sit in one provider's database and their direct dial in another's, and neither has both on its own.
One provider missing a contact is normal. Stopping the search there is the mistake.
Why it matters
A single data provider typically verifies only part of the contacts you ask it about; coverage in the 40 to 60 percent range from one source alone is common industry experience, which means close to half your target accounts can come back with no usable contact at all. Waterfalling several providers against the same record is how that gap closes, because each additional source only has to fill in what the ones before it missed.
The alternative to a waterfall is not "no enrichment", it is a single-source lookup that quietly fails on a large share of accounts and leaves a consultant guessing at an email format or working from a stale number. That failure is invisible until a message bounces or a call reaches the wrong desk, by which point the account has already been touched with a mistake attached to it.
How boilr handles it
When boilr enriches a company or contact, it does not stop at the first source it checks. Your AI sales employee already draws on more than 10,000 sources; where one does not return a verified detail, the agent moves to the next until it lands a verified email, phone number or direct dial, or is confident enough in what it found to act. You never see the individual provider calls, only the outcome: a contact that has actually been checked.
That is different from stitching a waterfall together yourself in a tool like Clay, where someone still has to design the sequence, maintain the rules and decide when a lower-confidence result is good enough to use. In boilr the waterfall runs automatically behind every enrichment, and the verified result is stored in the Company Brain, so the next task for that account starts from a checked record instead of repeating the search.
