B2B lead generation software UK teams use to find buyers, not names
Most B2B lead generation software hands you a filtered database and calls it pipeline. TAMI tells you which UK companies are in market this week, so your reps work the 40 accounts worth calling instead of 4,000 names.
We scan UK company websites daily for hiring, platform switches and new payment providers. You get the companies that are moving, matched to verified decision-makers with deliverable emails and direct dials, pushed straight into your CRM.
1.6m UK companies. 36m verified contacts. Under 5% bounce.
No card needed. Run your ICP through the database before you pay for anything.
Filter by what a company actually runs. Not by what it filed at Companies House.
Build a list of UK Shopify merchants over £5m running Klarna and shipping with DPD. Our patented merchant detection reads payment providers, carriers, BNPL and tech stack from live sites.
What is B2B lead generation?
B2B lead generation is the process of identifying businesses that fit your ideal customer profile, finding the people inside them who make the buying decision, and starting a conversation. It runs on two things: knowing which companies to approach, and knowing enough about them to be worth a reply.
Doing that at any scale means software. B2B lead generation software supplies the company data, surfaces verified decision-maker contacts and delivers them into your CRM, and the better platforms add timing, showing which of those accounts are doing something right now.
In the UK the category gets confused with two others. An agency sells you outcomes and keeps the targeting. A list broker sells you a file that starts decaying on arrival. Software sells you control: your team sets the targeting, sees the data before committing to it, and keeps it current.
Where does data usually leak in B2B lead gen?
Three places the outbound maths breaks, and what actually closes them.
The list was never targeted
SIC codes are chosen at incorporation to satisfy a filing requirement. Filter on that and your 1,000 contains maybe 300 real prospects. TAMI classifies every UK company from live website signals instead, so what you filter on is what the business actually does today.
The data isn’t real time
A static list treats a company that just migrated platforms identically to one that renewed with a competitor last week. TAMI tracks hiring, platform migrations, vendor switches and new payment providers, so the list is ordered by timing rather than alphabetically.
A fifth of it doesn't arrive
Most providers run above 20% bounce. Beyond the wasted sends, mailbox providers read the pattern as a purchased list and start filtering the messages that would have landed. TAMI verifies at inbox level and holds bounce under 5%.
TAMI closes all three.
1.6m UK companies classified from live website signals, ordered by who is showing buying activity this month, with contacts verified at inbox level and bounce held under 5%.
LEADS THAT PICK UP THE PHONE, NOT RECORDS THAT SIT IN A CSV
You don't have a lead shortage. You have a "which of these 4,000 is worth a call this week" problem.
A company hiring three SDRs, migrating off WooCommerce or adding a second payment provider is in a buying window. Your reps get 40 accounts with a reason attached instead of 4,000 names with nothing. Same headcount, different conversation rate.
TAMI holds 3.6x the UK contacts of ZoomInfo or Cognism at a quarter of the bounce rate. Check your own ICP against it before you spend anything.

Three lists your current B2B lead generation software can't return
Most platforms can't build lists this specific. TAMI can.
One
UK Shopify merchants turning over £5m or more, running Klarna, shipping with DPD.
Two
UK companies that switched ecommerce platform in the last 90 days and have posted a commercial hire since.
Three
The 400 UK businesses most similar to your 20 best closed-won accounts, ranked by shared technology and payment stack.
With TAMI, that's not an issue.
Each returns companies with verified decision-maker contacts attached, exportable to your CRM and deduplicated on import.
What can you actually filter on?
Most B2B lead generation software gives you industry, size and location. Here's what TAMI gives you.
Ecommerce merchants
Real trading merchants, found by our European patent. Not every site with a cart plugin.
Payment providers and BNPL
Filter by processor, payment method, and whether they've added Klarna or Clearpay.
Shipping and cross-border
Find UK businesses fulfilling into the EU, by carrier and destination market.
Full tech stack
Ecommerce platform, martech, cloud hosting and banking, read from the live site.
Hiring and growth
Companies adding commercial headcount are companies with budget. Catch them early.
Lookalikes from closed-won
Upload your best 20 accounts. Get the UK companies that match them.
Build lists your competitors can't.
Build a list of UK Shopify merchants over £5m running Klarna and shipping with DPD. Nothing else on your shortlist returns that.
WHY OUR LISTS CONVERT WHEN BOUGHT LISTS DON'T
We don't resell databases. Every UK company is classified by AI from live website signals, not from a code chosen years ago to satisfy a filing requirement. Every contact is verified at inbox level, not guessed from a name pattern. Every export lands in your CRM deduplicated against what you already hold. That's the difference between a lead list and a cleaning job.

Is B2B lead generation legal in the UK?
Yes, if the data is sourced properly. PECR's email rule doesn't apply to corporate subscribers, so you don't need consent to email a limited company. Watch the edges: some partnerships and sole traders count as individuals, and UK GDPR still covers the record. TAMI processes all UK and EU data under documented lawful basis, with source transparency and managed suppression.
How TAMI compares to other B2B lead generation software in the UK
Most UK shortlists come down to these three. ZoomInfo owns North American enterprise. Cognism leads on verified mobiles. Apollo bundles sequencing at the lowest price. TAMI wins when your buyers are defined by what they run, sell and ship.

6 questions to ask before you commit to B2B lead generation software in the UK
What's your UK-only count?
Global totals hide thin UK coverage that skews to enterprises with a US parent. (TAMI: 36m)
What's your bounce rate?
Anything over 5% damages your sending domain inside a quarter. (TAMI: under 5%)
How often does your data refresh?
UK contact data decays around 2.5% a month. Quarterly rebuilds arrive six weeks stale. (TAMI: continuous)
What signals come with it?
A record says a company exists. A signal says it's in market. (TAMI: included, not an upgrade)
How are companies classified?
If the answer is SIC codes, you inherit every wrong classification in the register. (TAMI: AI, from live sites)
Can I see it before I pay?
Anyone confident in their coverage lets you run your ICP through it first. (TAMI: free, no card)
Record count is the easiest number to inflate. UK depth, bounce rate, refresh, and signals decide whether a list becomes pipeline.
