Where do the leads come from?

Apollo, LinkedIn Sales Navigator, ZoomInfo, and 20+ specialty databases — routed through Clay waterfalls for the best coverage per persona. We source, don't scrape.

How accurate is the enrichment?

95%+ verified email match rate and 70%+ verified mobile phone match rate on our standard waterfall. Every email is validated before it hits a sequence, so bounce rates stay under 2%.

Do you dedupe against my CRM?

Yes. We pull an export from your CRM at kickoff, then continuously suppress accounts and contacts that already exist as customers, opportunities, or active leads owned by AEs.

What triggers do you monitor?

Funding rounds, key hires, tech stack changes, layoffs, product launches, and custom signals per ICP. Triggered accounts get routed into faster, higher-priority cadences.

How often are lists refreshed?

Weekly. Every Monday you get a fresh batch of triggered accounts and net-new prospects, deduped and scored — not a static list that gets stale by month two.

Back to Depth Scale

Why reps only work prospects worth working.

Reps don't miss quota because they can't sell — they miss quota because the list was garbage. Everything we ship starts here: a scored, enriched, trigger-based account universe.

How list building is implemented, week by week.

The channel enters the same 14-day build, approval loop and measurement plan as the rest of your outbound engine.

1
Days 1 to 14
20 question intake, domains bought and authenticated, list one built in Clay, three angles written, approved and launched.
2
Week 2
Calling live, volume ramps, recordings shared from day one, first conversations start.
3
Month 1
1,000 dials a week per caller. Three angles left untouched. First meetings from week three.
4
Month 2
Losing angles killed, ICP tightened on disposition data, objection library written.
5
Month 3
Playbook handed over. Monthly meeting number agreed in writing. First exit gate.
6
Months 4 to 6
Second play, new segment, monthly insight report, quarterly gate.

What we put in writing.

Live in 14 days from signature, or month one is free.
1,000 dials a week per caller, evidenced in the dialer, not claimed in a slide.
A weekly report with real learnings, or that week is free.
Every list, script, sequence, recording and playbook is yours, during and after.
Quarterly exit gates. If we are the reason it is not working, you leave.
We will not invent a meeting number before your market has answered.
