Lists that don't have 12 ghosts and 3 wrong emails per 100.
Bad data kills campaigns before they start. We build ICP-fit lists using waterfall enrichment across 16+ sources, triple-verify every record, and deliver contacts that are actually reachable.
Why single-source lists don't work
Pulling a list from Apollo or ZoomInfo gives you one vendor's data. That vendor has gaps, stale records, and wrong emails. Waterfall enrichment queries 16+ data sources in sequence, cross-referencing and validating each record. The result: 30-50% more valid emails than any single source, with bounce rates under 3%. We don't just buy lists. We build them.
How we build your list
- 1
ICP definition
We map your ideal customer profile: industry, company size, revenue, tech stack, title patterns, geography, and exclusion criteria. The list starts with targeting, not a database dump.
- 2
Waterfall enrichment
Each prospect is run through 16+ data sources in priority order. If source one doesn't have the email, source two does. If source two's email is stale, source three has the current one.
- 3
Triple verification
Every email is verified through three independent verification services. Catch-all domains get additional validation. Role-based addresses are flagged and excluded by default.
- 4
Delivery

Frequently asked questions
What data sources do you use?
We use a mix of premium and proprietary sources including Apollo, ZoomInfo, Lusha, RocketReach, Hunter, Clearbit, PeopleDataLabs, and several others. The specific waterfall order is tuned per ICP.
What bounce rate should I expect?
Under 3% on average. We guarantee under 5%. If a list bounces higher, we replace the bad records at no cost.
Can you build lists for niche industries?
Yes. Our waterfall approach works especially well for niche ICPs where no single source has good coverage. The more sources we query, the better the result for hard-to-find contacts.
How fast can you deliver a list?
Standard turnaround is 3-5 business days for lists of 1,000-5,000 contacts. Larger or more complex lists take 5-7 days. Rush delivery is available.
