FinTech leads that show you the whole payment stack
We hold fintech leads for UK merchants filtered by the processors they run, the wallets and BNPL options at their checkout, and the currencies they accept. Your reps open knowing what is already there and what is missing.
TAMI AI reads live checkouts and detects every payment provider present, alongside the platform, the carriers, and the trading status. That turns a company list into a merchant list, each with the finance and digital decision-makers attached.
1.6m UK companies. 36m verified contacts. Payment stack on every merchant record.
No card needed. Pick a processor and see which UK merchants currently run it.
Filter by processor. Filter by wallet. Filter by currency.
Merchants rarely run one provider. A primary acquirer, a backup, a regional gateway and two wallets is normal, which is why share of checkout matters more than displacement.
What are fintech leads?
FinTech leads are businesses that could buy payment, lending or financial infrastructure from you, along with the people inside them who choose providers. For a PSP, gateway, acquirer or BNPL provider, the merchant is the account and the finance, ecommerce or product lead is the contact.
They are unusually hard to source from conventional data. Nothing filed at Companies House says a business takes card payments, which provider processes them, or how much it turns over online. Two retailers of identical size can run enterprise acquiring or nothing at all.
Useful fintech leads therefore depend on reading the checkout rather than filtering a company database.
What makes these fintech leads different
Three things a conventional prospect list cannot give you.
The full payment stack, not one provider
Every processor, wallet and BNPL option detected at the checkout, so you see what you are competing alongside rather than guessing at a single incumbent.
Volume and currency signals
Revenue band, currencies accepted and international storefronts, which is how pricing conversations start in payments.
The people who choose providers
Finance, ecommerce and product leads with verified emails and direct dials, so a merchant is a lead rather than a research task.
TAMI AI gives you UK merchants with the processor, the wallets, the currencies and the contacts on the same record. One Fortune 500 client used this data to enter the payments market and reach a top five position within three years.
NOBODY RUNS ONE PAYMENT PROVIDER
This is a share of the checkout market, not a winner-takes-all one.
That changes the conversation. A merchant with no wallet support, no BNPL or no multi-currency capability has a gap you can name, which is a far better opening than asking who handles their payments.

Three questions any merchant list should answer
One
Does this business actually take payments online, and at what scale?
Two
Which providers are already at the checkout, and what is missing?
Three
Who signs off the payments decision, and can I reach them?
Not a company list. Merchants with their stack named.
Every answer comes back as a merchant record with the payment stack, the currencies and the decision-makers attached.
What you can filter your fintech leads by
Sector and headcount describe any company. These describe a merchant.
Processor and gateway
Which payment providers are live at the checkout, detected from the site itself.
Payment methods
Cards, wallets, direct debit and local methods accepted per merchant.
BNPL adoption
Whether Klarna, Clearpay or another instalment option is offered.
Currencies and cross-border
Which currencies are accepted and which markets are served.
Revenue and traffic band
Merchant scale, which is what pricing conversations actually turn on.
Verified trading status
Whether the business genuinely sells, so dormant sites stay out.
Combine any of them. Every UK merchant over £5m running a named processor without BNPL is a single query.
WE READ THE CHECKOUT, NOT THE FILING
Conventional B2B data describes what a company registered. TAMI AI reads what happens at its checkout, which is the only way to know a business takes payments at all. That detection is covered by a European patent, and it is why processor, wallet, BNPL and currency data exist as filters rather than as fields you would assemble from three vendors.

What you receive when you build a merchant list
These are the six things that land in your hands.
- The merchant list Every UK business matching your processor, method and volume criteria, exportable.

- The gaps identified Which methods, wallets or currencies are absent, which is your opening.

- CRM delivery Synced and deduplicated against records you already hold, so nothing arrives twice.
- Provider change alerts Notification when a merchant adds or switches a payment provider.
Is buying fintech contact data legal in the UK?
Yes, with documented sourcing. Checkout and processor detection reads published website data and involves no personal data. Named contacts do, so UK GDPR requires a lawful basis, source transparency and suppression. PECR's email rule excludes corporate subscribers, though sole traders and some partnerships count as individuals.

How to build a payments prospect list
Start from the checkout, not the sector
Retail and hospitality contain merchants processing millions and businesses taking nothing online. Detected payment activity is the qualifier.
Map the whole stack, not the primary provider
A merchant running three providers is a different conversation from one running a single acquirer. Both are opportunities, but not the same one.
Look for the missing method
No wallet support, no BNPL, no local payment methods in a market they serve. Absence is easier to sell against than presence.
Qualify on volume before you quote
Revenue band, traffic signals and currency count separate merchants where your rates are competitive from ones where they are not.
Watch for provider changes and re-platforms
Both put payments back in contention. TAMI AI surfaces them as they happen rather than at your next list refresh.
Reach finance and ecommerce together
Payments decisions rarely sit with one function. Finance owns the cost, ecommerce owns the conversion, and both need to agree.
In payments, the qualifier is the checkout, not the industry. What a merchant already runs tells you what it still needs.
WHAT PAYMENTS TEAMS DO WITH IT
Find UK merchants running a rival processor
- Filter by payment methods and currencies accepted
- Catch checkout changes while the decision is open
- Qualify on revenue band before quoting rates
- Reach finance and ecommerce leads together
- Target merchants with no instalment option live
- Find stores adding a second provider
- Identify multi-currency merchants needing local methods
- Separate enterprise retailers from long-tail stores
- Export straight into your CRM or sequencer
Every prospect that turns out not to take payments costs a rep a call. Filter for the checkout first.
PAYMENT COMPANY DATA, FOR THE OTHER DIRECTION
Not everyone reading this sells payments. Plenty of teams sell compliance, fraud tooling, infrastructure and professional services to the providers themselves.
- TAMI AI's payment company data covers UK PSPs, gateways, acquirers and fintechs by region, technology in use and trading status, with the product and commercial contacts attached.
- Stripe, United States Postal Service, Trustpilot and DHL use TAMI AI to understand the payments market.
