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.

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%.

BUILT FOR PIPELINE

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. 

TAMI scans UK company websites daily for hiring, platform migrations, vendor switches and new payment providers, then ranks your market by which companies are showing those signals right now.

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. 

FEEDBACK

WHAT OUR CLIENTS THINK OF TAMI AI

  • With TAMI, we can find valuable insights into target companies fast and accurately. It's a great tool for sales teams looking to increase their revenue.
    Foteini T
    Sales Manager
  • Our company already has a big market share in the domain of online payments and we couldn't find new leads using the existing tools. With TAMI, within two days, I found more than 40 new leads from companies I'd never heard of before. A real eye-opener!
    Chun Kay T
    Sales Lead
  • One of the best tools for qualifying and identifying companies that aren't found in other databases. Excellent for cross referencing with other tools. Strong tech information too.

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.

TAMI AI

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.

CRM CONTACT ALERTS

What you get on every record with TAMI

Ask any provider what's inside a lead. The answers get vague fast. Not with TAMI.

  • Verified email Checked at inbox level, not guessed from a name pattern.
  • Direct dial Straight to the decision-maker, not the switchboard.
  • Current job title Re-verified continuously. Under 5% bounce, 95% deliverability.
  • Company signals What they run, who processes their payments, who ships their orders.
  • Firmographics Region, headcount band, revenue band, across England, Scotland, Wales and Northern Ireland.
  • CRM-ready Deduplicated on import to Salesforce, HubSpot, Pipedrive, Close and Mailchimp.

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

6 questions to ask before you commit to B2B lead generation software in the UK

1

What's your UK-only count?

Global totals hide thin UK coverage that skews to enterprises with a US parent. (TAMI: 36m)

2

What's your bounce rate?

Anything over 5% damages your sending domain inside a quarter. (TAMI: under 5%)

3

How often does your data refresh?

UK contact data decays around 2.5% a month. Quarterly rebuilds arrive six weeks stale. (TAMI: continuous)

4

What signals come with it?

A record says a company exists. A signal says it's in market. (TAMI: included, not an upgrade)

5

How are companies classified?

If the answer is SIC codes, you inherit every wrong classification in the register. (TAMI: AI, from live sites)

6

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.

Frequently asked
questions

1What's the best B2B lead generation software in the UK?
It depends on your ICP. TAMI leads on UK coverage at 36m contacts and on merchant, payments, shipping and technology signals, making it the strongest fit for ecommerce, fintech and logistics. ZoomInfo leads on North American depth, Cognism on phone-verified mobiles, Apollo on price with built-in sequencing
2How is lead generation software different from an agency?
An agency runs campaigns on a retainer and keeps the targeting knowledge. Software gives your team direct control of segmentation, data and CRM delivery. Agencies suit teams with no SDR capacity. Software suits teams building an outbound motion they intend to own and improve.
3How much does B2B lead generation software cost in the UK?
Pricing varies by database access, seats and enrichment volume, and typically sits below the cost of one additional SDR. TAMI offers packages from Growth to Enterprise, plus a free account so you can test your ICP against the database before any commercial conversation.
4Is B2B lead generation legal in the UK?
Yes, when data is sourced and processed lawfully. PECR's electronic mail rule does not apply to corporate subscribers, so B2B email to limited companies needs no prior consent, though some partnerships and sole traders count as individuals. UK GDPR still applies, requiring documented lawful basis such as legitimate interests.
5How many UK companies and contacts does TAMI hold?
TAMI holds 36 million UK contacts across 1.6 million UK companies, mapped from live website signals rather than static industry codes. Coverage spans England, Scotland, Wales and Northern Ireland, filterable by region, headcount band, revenue band, technology stack and trading activity.
6Do you cover global markets or UK only?
TAMI covers global markets with 458 million contacts, and holds unusually deep UK coverage within that. You can segment by country, region or city, then layer industry, size and technology filters on top for tightly targeted UK campaigns.
7Can I build lookalike lists from my best customers?
Yes. Upload closed-won accounts and TAMI's lookalike modelling identifies shared traits including technology stack, payment provider, size band and region, then returns the UK companies that match. Most teams surface segments their original ICP document missed entirely.
8How often is TAMI's data updated?
Continuously. Company signals are tracked daily and contact records are verified on an ongoing basis rather than rebuilt quarterly. When someone changes role or leaves a company, the change is flagged and pushed into your CRM as an alert.
9How accurate are TAMI's UK email addresses?
TAMI maintains 95% deliverability and holds bounce under 5%, against over 20% at most providers. Addresses are verified at inbox level rather than generated from name patterns, and records are re-verified continuously rather than rebuilt in batches that arrive already stale.
10Does TAMI integrate with my CRM?
Yes. TAMI syncs with Salesforce, HubSpot, Pipedrive, Close and Mailchimp, deduplicating against existing records on import. Contact changes and job moves push through as alerts, so records stay current inside the CRM instead of requiring a periodic manual clean.
11Can I filter by UK region or industry?
Yes. Filter by nation, region, city, industry, headcount band and revenue band, then layer live signals on top so the list contains only companies currently hiring, switching vendors or adopting a specific technology rather than everything in the category.
12Where does TAMI source its data?
TAMI does not resell third-party databases. Company records are classified by AI from live website signals rather than static SIC or NAICS codes, and every contact is independently verified before entering the database. Sourcing methodology is documented and available to your DPO.
13How quickly can I build my first list?
Most teams build and export a working list in their first session. Setup is immediate, filters run in-platform, contacts are visible before export, and records sync straight into your CRM. There's no implementation project and no development work required.

Your reps aren't short of names.
They're short of reasons to call
