Why this customer remains anonymous
TAMI works with hundreds of companies globally across Fintech, Payments, eCommerce, Shipping, Logistics and MarTech. We're proud of the brands we count as customers, and even prouder of the trust they place in us.
For some of those relationships, that trust comes with a confidentiality clause: we're not permitted to name them as customers, publicly or otherwise. This is one of those stories.
We think that's worth saying out loud, not hiding. The results below are real, the data is real, and the only thing we're withholding is the name - because that's exactly what a trusted partner does.
The Problem
Bad data was capping campaign performance.
This UK-based MarTech company was scaling its market share and sharpening its email campaigns - relying on BuiltWith for technographics, and ZoomInfo and Cognism for contact and campaign data. All three are widely used. None of them were giving an accurate picture.
That's not a data-volume problem.
It's a data-accuracy problem.

"We were paying for three different data providers and still couldn't trust the numbers. TAMI was the first platform where the data actually matched reality - no ghost sites, no companies counted five times over."

The Solution
Why the switch worked: TAMI's three pillars
The 10X conversion uplift didn't come from a bigger list or more sends. It came from replacing unreliable vendor data with a platform built to be accurate at the source - and to keep working after the first campaign.
Here's what made the difference:
Clean, verified technographic data
Why it mattered for the MarTech company
BuiltWith's technology reporting was often wrong, included sites that were no longer active, and inflated company counts by treating every localised domain as a separate business. Somfy.com was counted 65 times for a single technology - noise that made it hard to trust the data enough to act on it.
How TAMI solved it
TAMI removed the false positives, stripped out inactive sites, and consolidated regional domains back to the parent company.
→ A market research foundation the team could actually rely on.
Conversion-driving campaign data
Why it mattered for the MarTech Company
The company ran the same email campaigns in parallel across Cognism, ZoomInfo, and TAMI, to see which data actually converted once it reached an inbox.
How TAMI solved it
TAMI delivered a 95% email delivery rate - but the real gap was in what happened next: TAMI-sourced leads converted at 10X the rate of ZoomInfo and Cognism on the same campaigns.
→ Same effort, same campaign - dramatically more leads converted.
AI-powered lookalike modelling
Why it mattered for the MarTech Company
Beyond the immediate campaign, the company wanted two repeatable motions: winning competitors' customers, and finding more prospects like their best existing ones - without weeks of manual research each time.
How TAMI solved it
TAMI's AI identified competitor customers to target directly, and separately surfaced lookalike retailers matching their top customers - several with meaningfully higher revenue potential than an average prospect.
→ Two new, always-on sources of qualified pipeline.

"Same campaign, same list size, completely different result. Seeing a 10X jump in conversions from the exact same effort was the moment it stopped being a data project and started being a revenue one."
