The real problem

Your outbound is only as good as your lead data.

You can have the best offer and the sharpest copy, but point it at bad data and the whole engine stalls. Most "lead lists" quietly cost you more than they deliver.

Bounced emailsInvalid addresses spike your bounce rate and burn sends.
Wasted SDR timeReps scrub spreadsheets instead of starting conversations.
Low reply ratesGeneric, mistargeted records get ignored or marked spam.
Poor targetingWrong companies and roles mean your offer never fits.
Damaged domain reputationHigh bounces and spam flags push you into the junk folder.
Bad campaign decisionsSkewed data leads to the wrong calls on what's working.
The ICP-First method

We define your buyer before we deliver a single lead.

No volume dump. Four structured steps take us from your exact ICP to real-time, validated delivery, with you signing off before anything scales.

The difference

Data dumps vs Velocity GTM.

Most providers sell volume, a filtered list dumped as a stale CSV. We sell precision: every lead matched, double-verified, and delivered with the receipts.

The in-house math

Cheaper than the tools alone.

Building this yourself means licensing the full data stack, then hiring someone to run it. Velocity replaces both, for less than the software costs.

FAQ

Questions, answered.

Where do the leads come from?
We use Clay-powered workflows with multiple data sources, enrichment layers, and verification tools. The exact sources depend on your ICP and campaign goals.
Do you write outbound emails too?
The core service is lead sourcing and enrichment. We can include personalization angles and buying triggers so your copywriter or SDR team can write better outreach.
Can I review leads before paying monthly?
Yes. You can request 20 sample leads to evaluate quality before committing.
What counts as a qualified lead?
A lead that matches the agreed ICP criteria, has relevant company and contact data, and includes a verified work email when available.
What happens if emails bounce?
If the delivered batch exceeds the <1% bounce guarantee, we replace the bad leads or rebuild the affected segment.
Is this just Apollo data?
No. Apollo may be one source depending on the ICP, but the value is in the workflow, filtering, enrichment, verification, and ICP matching.
Who is this not for?
This is not for companies that want cheap generic lists, consumer leads, or mass scraped data with no targeting.
