Why pick one database,
when you can > waterfall them all?
Stop relying on a single tool for emails and phone numbers. With waterfall enrichment you tap a stack of databases until one returns a verified hit — and the stack is ranked by your reply rate, not someone else's.
>find work emails.
Start with a LinkedIn profile URL — or a name plus company domain. The work-email waterfall taps a stack of verified providers, first valid match wins, the rest fall back. Validated before the lead lands in your audience.
>find personal emails.
Personal emails expand your retargeting reach — not just inbox. We match them into LinkedIn, Google, Meta, and TikTok ad audiences so you reach the same buyer wherever they scroll, even if their work address never opens.
>find phone numbers.
Same pattern, applied to phones. The mobile waterfall pulls from providers that excel at mobile data — first valid number wins, and we validate every match with a separate verification call.
>find social handles.
One name in, every handle out — LinkedIn, X, Reddit, YouTube, Substack, TikTok. Multichannel beats single-channel: the rep who comments on the LinkedIn post AND replies to the cold email gets the meeting. Cached forever, since handles don't change.
> what makes ours different.
Max coverage. Max reply rate. Bring your data. Free yourself.
>max coverage.
Unstuck runs the waterfall on your behalf. One subscription, no provider accounts to manage, no credentials to rotate, no per-provider invoices. Three times the coverage of a single-provider setup, none of the operational tax.
>max reply rate.
Most waterfalls rank by static cost. Ours ranks by predicted reply rate, per customer — providers whose contacts actually convert climb the stack; ones whose contacts bounce drop. The waterfall gets smarter for your audience the longer you run it.
>byo enrichment.
Already have leads with emails or phones? Drop them in via webhook (push events as they happen) or CSV upload (bulk import). Enriched fields stay in sync with what our waterfall finds — we only call providers when a field is missing or stale. No double-billing.
