SaaS sales leads filtered by the software they already run

We hold SaaS sales leads for UK companies filtered by the software they already run, so you can target the businesses using your integration partner, your competitor, or the legacy tool you replace. The word "businesses" gives the reader something concrete to picture.

TAMI AI reads live company websites and detects the platforms, martech, analytics, hosting, and payment tools each business runs. That turns a company list into a stack-qualified prospect list, with the technical and commercial decision-makers attached.

1.6m UK companies. 36m verified contacts. Full stack on every record.

No card needed. Name a tool and see which UK companies run it.

Are you integrating, replacing, or explaining?

Those are three different sales conversations, and the stack tells you which one you are walking into. A company already running your integration partner is warm. One running your rival has a renewal coming. One running nothing in your category has not felt the problem yet.

What are SaaS sales leads?

SaaS sales leads are businesses that could buy your software, along with the people inside them who evaluate and approve it. For most vendors, that means a mid-market or enterprise company with a specific operational problem, and a buying group spanning the team that will use the product and the one that has to integrate it.

The difficulty is that software sells across every sector, so industry is a weak qualifier. What separates a real prospect from a plausible one is the stack.

A company already running your integration partner is a warm introduction. One running your competitor is a displacement play with a renewal date. One running nothing in your category may not have the problem yet. Useful SaaS sales leads therefore start with detection rather than firmographics.

What makes these SaaS sales leads different

Three things a firmographic list cannot give you.

The stack, not the sector

Every platform, martech, analytics, and hosting tool detected per company, so your ICP can be defined by software rather than by SIC code.

The competitor install base

Which UK businesses run a rival product, so displacement campaigns start with the incumbent named.

The buying group attached

Technical and commercial decision-makers with verified emails and direct dials, because software decisions are rarely made by one person.

TAMI AI gives you UK companies with the full stack, the incumbent and the contacts on the same record. On one UK martech engagement, lists built this way held 95% email deliverability against providers running above 20% bounce.

BUILT FOR SOFTWARE SALES

YOUR ICP IS A STACK, NOT A SECTOR

Two companies of identical size and industry can be a perfect fit and a total waste of a quarter.

TAMI AI detects what each UK business actually runs, so a prospect list can be built around integration fit, competitive displacement, or a missing category.

That is the difference between selling to an industry and selling to a problem. A company running a legacy tool you replace has the problem today. One in the same sector running nothing may not have it for two years.

    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!

Three questions any SaaS prospect list should answer

One

What does this company already run in and around my category?

Two

Am I integrating, displacing, or creating the need from nothing?

Three

Who evaluates the software and who signs for it?

Not a company list. Stack-qualified prospects.

Every answer comes back as a company record with the detected stack, the incumbent, and the buying group attached.

What you can filter your SaaS sales leads by

Sector and headcount describe any company. These describe a software buyer.

Tools in use

Every detected product across martech, analytics, CRM, support and commerce.

Platform and CMS

What the website and commerce layer runs on, which shapes integration effort.

Hosting and infrastructure

Cloud provider and CDN, useful when your product sits close to the infrastructure.

Category gaps

Companies running nothing in your category, for creation rather than displacement.

Growth signals

Hiring and expansion activity, which usually precedes tooling budget.

Size, revenue and region

Firmographics as the secondary filter they should be.

Combine any of them. Every UK company over 100 staff running a named analytics tool but no CRM is a single query.

TAMI AI

WE READ THE STACK, NOT THE SIC CODE

Conventional B2B data describes what a company registered years ago. TAMI AI reads what it runs today, which is the only qualifier that actually predicts software fit. Detection covers martech, analytics, platform, hosting and payments, and every field also works as a filter, so a technology signal becomes a prospect list rather than a report.

CRM CONTACT ALERTS

What you receive when you build a SaaS prospect list

These are the six things that land in your hands with our SaaS sales leads.

  • The prospect list Every UK company matching your stack and firmographic criteria, exportable.
  • The incumbent named Which competing or adjacent product each account runs, so reps know the position.
  • Integration fit flagged Whether the account already runs the tools you connect to.
  • The buying group Technical and commercial contacts with verified emails and direct dials.
  • CRM delivery Synced and deduplicated against records you already hold, so nothing arrives twice.
  • Stack change alerts Notification when an account adds or removes a product in your category.

Is buying SaaS contact data legal in the UK?

Yes, with documented sourcing. Technology 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 SaaS prospect list, in six steps

1

Define the play before the list

Integration, displacement or category creation need different filters, different messages and different expectations. Pick one per campaign.

2

Start from the tool, not the industry

Software fit is predicted by what a company runs, not by the sector it registered in. Detection is the qualifier.

3

Check adjacency, not just competition

A company running your integration partner is often a warmer prospect than one running your direct rival, because there is no incumbent to remove.

4

Use absence deliberately

Companies running nothing in your category are either early or uninterested. Treat them as a separate, longer motion rather than mixing them in.

5

Watch removals as closely as installs

A tool disappearing is a stronger signal than one appearing. TAMI AI surfaces both as they happen rather than at your next list refresh.

6

Map the buying group, not the champion

Software decisions need the user, the integrator and the budget holder. A single contact per account is where most SaaS sequences stall.

In software the qualifier is the stack. What a company already runs tells you whether you are selling a replacement, an addition or an education.

ACCOUNTS YOU CAN QUALIFY

WHAT SOFTWARE TEAMS DO WITH IT

TAMI AI FOR SALES
  • Find UK companies running a competitor's product
  • Prioritise accounts running your integration partners
  • Catch tool removals while the gap is still open
  • Disqualify on stack before spending a call
  • Reach the technical and commercial buyer together
TAMI AI FOR MARKETING AND PRODUCT
  • Build audiences by detected tool rather than sector
  • Size adoption of the products you integrate with
  • Validate demand before building a connector
  • Track category share across recent quarters
  • Export straight into your CRM or sequencer

Every account that turns out to run nothing in your category costs a rep a quarter. Filter on the stack first.

SELLING INTO MARTECH

MARTECH COMPANY DATA, FOR THE OTHER DIRECTION

Not everyone reading this sells software to businesses. Plenty of teams sell infrastructure, data, services and finance to the software vendors themselves.

  • TAMI AI's martech company data covers UK SaaS and martech companies by region, size, technology in use and growth signals, with the product and commercial contacts attached.
  • Stripe, United States Postal Service, Trustpilot and DHL use TAMI AI to understand the technology market.

Frequently asked
questions

1How do you find companies whose contract with a competitor is ending?
You cannot see contract dates, but you can see the behaviour around them. A second tool in the same category appearing, or a new technical hire, usually means an evaluation started before the renewal date.
2What is the average sales cycle for B2B SaaS?
Roughly one to three months for small deals, six to twelve for enterprise. What moves it most is how many teams the product touches, since each additional stakeholder adds weeks rather than days.
3Should early-stage SaaS companies buy leads or do founder-led outbound?
Both, in that order. Founder-led outbound teaches you who actually buys, and bought lists are only useful once you know which stack pattern to filter for. Buying first tends to burn the domain.
4How many contacts do you need per account for a SaaS deal?
Three to five in most mid-market deals: the user, the person who integrates it, and whoever signs. Single-threaded deals stall when the champion changes role, which happens constantly in software.
5Can you tell how much a company spends on software?
Not directly from web signals. Stack depth, headcount and the tier of products detected give a reasonable indication, but actual spend sits in contracts, which is what enterprise intelligence providers mine instead.
6How do you sell against a free or open-source alternative?
Detect it first, because the objection is different. Companies running an open-source tool have chosen control over convenience, so the pitch is total cost and maintenance rather than features.
7What is the difference between technographic and intent data for SaaS?
Technographics tell you what a company runs, which predicts fit. Intent tells you what it is researching, which predicts timing. Fit without timing wastes sequences, timing without fit wastes calls.
8How do you find companies that just raised funding?
Funding data comes from investor and filing sources rather than websites. What is detectable afterwards is the spending: new tools appearing, hiring, and expansion into new markets, usually within a quarter of a round.
9Which job titles actually evaluate SaaS products?
Depends on category. Marketing tools go to demand gen and RevOps, developer tools to engineering leads, and anything touching data to IT and security. The budget holder is rarely the evaluator.
10Can I target companies by the cloud provider they use?
Yes, where the infrastructure is web-visible. Cloud provider and CDN are detectable, which matters if your product deploys into a specific environment or your pricing depends on where the workload sits.
11How do you avoid pitching companies that already use your product?
Suppress your own customers before export. Any list built on stack detection will return your existing base first, since they match your criteria most closely of anyone in the market.
12 What is martech company data used for by recruiters and investors?
Identifying UK SaaS and martech companies by size, growth signals and technology in use. Recruiters use it for candidate mapping, investors for sourcing and diligence on adoption.
13Do SaaS sales leads work for PLG companies as well as sales-led ones?
Yes, differently. Product-led teams use stack data to prioritise which self-serve signups deserve a human, rather than to build outbound lists. Same detection, applied after signup instead of before contact.
