Customer and competitor analysis that names the accounts, not just the trends

Most customer and competitor analysis ends in a positioning slide. TAMI ends it with a list: every company running your competitor's product, what else is in their stack, and who to call inside them.

We read live company websites and detect the platforms, payment providers, carriers and tools each business runs. That turns any competitor into a customer list you can size, segment and work, with verified contacts attached.

1.6m UK companies. Every vendor detected, per site, refreshed continuously.

No card needed. Pick a competitor and see how many of their customers we find.

Market share tells you that you lost. Not to whom.

Reported share comes from vendors describing themselves. Detected share comes from reading which companies actually run which product. One is a percentage. The other is a list of accounts with renewal dates.

What is customer and competitor analysis?

Customer and competitor analysis is the practice of understanding who buys in your category, who they currently buy from, and what separates the accounts you win from the ones you lose. It covers your own customer base, your competitors' customer bases, and the overlap between them.

Most versions of it stop at the strategic layer: market share estimates, feature grids, positioning maps. Useful for a board deck, but useless on a Tuesday morning. The version that changes revenue is account-level. It names the companies, shows what each one runs, and identifies which of them look most like the customers you already win.

Why competitor analysis rarely reaches the sales team

Three failures, all producing the same outcome: a document nobody opens twice.

It was built on inflated data

Case studies, logo walls, and press releases show the customers a competitor wants you to see. TAMI detects vendors from live websites, so you see the whole installed base, including the mid-market accounts nobody writes a case study about.

It only described the market

A share percentage tells you where you stand. It doesn't tell your reps who to call on Monday. TAMI returns the companies behind the percentage, so analysis and target list are the same artefact.

It was just a snapshot

Vendor changes happen on renewal dates and re-platforms, and they're only useful if you catch them early. TAMI refreshes continuously, so a competitor losing an account shows up as movement rather than as something you learn about a year later.

Turn a competitor into a working list.

Every company running their product, what else they run, who to call, and what changed since last quarter.

BUILT FOR DISPLACEMENT

THEIR CUSTOMERS ALREADY BUY WHAT YOU SELL

No category education, no budget to create, no convincing anyone the problem exists.

TAMI finds every UK company running a competitor's product, so your team works accounts that have already proven they buy in this category.

Cold prospects need convincing the problem exists. A competitor's customer ran procurement, signed off budget and lived with the compromises. All that remains is whether they would choose again.

Pick a competitor and see how many of their UK customers we can name. The count is free.

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 questions your CRM can't answer

One

Which companies switched away from us in the last year, and which competitor took them?

Two

Of our competitor's UK customers, which ones most resemble the accounts we win and keep?

Three

Where does a competitor own the market outright, and where are they thin enough to attack?

Not a slide deck. A list with names on it.

Every answer comes back as a count, a segmentation and a company list with verified contacts, ready for sales without a second procurement round.

What you can detect with TAMI

Customer and competitor analysis is only as good as what you can see inside a company. Here's what we read from a live site.

Vendor and platform detection

Which ecommerce, martech, hosting and analytics products a company actually runs.

Payment and checkout stack

Processors, payment methods, currencies and BNPL, at merchant level.

Shipping and carrier relationships

Who fulfils for whom, by carrier and destination corridor.

Stack context

What a competitor's product sits alongside, so you know what you'd integrate with or replace.

Switching movement

Migrations, new installs and removals, showing which accounts are in play now.

Lookalike modelling

Upload your best customers and find the competitor accounts that share their traits.

Combine any of them.

Find every UK merchant over £5m running a rival checkout that shipped cross-border last quarter, then open the list. There's no limits to what you'll find.

TAMI AI

WE DETECT THE VENDOR. WE DON'T ASK AROUND

With TAMI, a competitor's customer base is read from live websites rather than assembled from case studies, review sites or survey panels. That decides whether a quiet mid-market account appears in your list at all, and it's why our maps hold up when clients check them against the deals they've personally lost.

CRM CONTACT ALERTS

What comes back when you map a competitor with TAMI

We don't give you a positioning matrix. Six things land in your hands, and every one of them is usable the same day.

  • The customer list Every company detected running their product, exportable.
  • Segment breakdown Region, size band, revenue band and vertical, so you see where they're strong and where they aren't.
  • Full stack per account What else each company runs, which is the opening line of your outreach.
  • Lookalike ranking Those accounts sorted by how closely they resemble your own best customers.
  • Named decision-makers Verified contacts inside those companies, for when analysis turns into a campaign.
  • Change tracking Installs and removals since last quarter, so switching windows surface early.

Where does TAMI's market intelligence data come from?

From the open web, read directly. We don't resell databases or buy panel data. We crawl live websites, detect the products, providers and payment infrastructure each business runs, then match those companies to verified contacts. All UK and EU data carries documented lawful basis and managed suppression.

How to run a competitor customer analysis, in six steps

1

Pick the competitor, not the category

Map one rival at a time. A category-wide view blurs the differences that decide which accounts are winnable.

2

Detect, don't infer

Build the list from what's running on live sites. Case studies and logo walls show a curated fraction of the truth.

3

Segment their base before you attack it

Split by size, region and vertical. Every competitor is dominant somewhere and thin somewhere else, and only one of those is worth your quarter.

4

Score against your own winners

Rank their customers by resemblance to the accounts you win and keep. Fit beats volume, every time.

5

Look for movement, not just presence

Recent installs, removals and re-platforms show which accounts are already reconsidering. Those are the conversations that convert.

6

Hand over names, not conclusions

The output should be a contactable list. Anything that stops at a percentage stops before the useful part.

A competitor map is only as good as its detection. Source, depth and refresh cycle decide whether you end up with a working target list or another slide nobody opens.

BETTER DECISIONS

YOUR OWN BASE

THE PATTERN IS ALREADY IN YOUR CUSTOMER LIST

Customer analysis comes first. It defines what a good competitor account actually looks like.

  • Upload your closed-won accounts and TAMI finds what they share: technology stack, payment provider, size band, region and trading behaviour.
  • That profile then ranks every competitor customer we detect, so the list arrives sorted by fit. Stripe, USPS, Trustpilot and DHL use TAMI this way.

Frequently asked
questions

1How do you win customers away from a competitor?
Find competitor customers first, then narrow to the accounts that resemble your best ones. Reach out when something changes: re-platforms, new payment providers and commercial hiring all signal a decision is already open.
2How many of a competitor's customers can you actually identify?
That depends on the product's visibility. Anything with a public footprint, such as ecommerce platforms, payment processors, carriers and analytics, is detected reliably. Internal systems with no web presence cannot be seen from outside.
3Can I see when a competitor's contract is up for renewal?
No. Contract dates are private. Customer and competitor analysis shows the behaviours that precede a review instead: platform migrations, new vendors appearing beside the incumbent, and commercial hiring. Those signals usually arrive earlier than renewal dates.
4How can I detect which of my own customers are at risk of switching?
Watch for a competitor's technology appearing alongside yours, or adjacent tools being swapped out. TAMI tracks installs and removals continuously, so a rival showing up in an existing account surfaces while you can still act.
5How do I find out which competitor won a deal we lost?
Check what the account runs now. Vendor detection shows which product went live after the decision, so win/loss analysis rests on what was actually implemented rather than what the buyer told your rep.
6Can a company use two competing vendors at once?
Often, yes. Larger businesses run overlapping tools during migrations, across regions or between departments. TAMI shows every detected vendor per company, so you can spot partial deployments where displacement is already half complete.
7How do I find whitespace in a competitor's customer base?
Segment their install base by size, region and vertical, then compare it against the total market. The gaps show where they have no presence, which is where a new entrant meets least resistance.
8How do I work out who my real competitors are?
Look at what your prospects run instead of you. Customer and competitor analysis built on live website data regularly surfaces rivals nobody listed internally, including in-house builds and tools from adjacent categories.
9Does this work if my competitors sell services, not software?
Partially. Service providers leave fewer detectable traces than software. Where they integrate with a website, such as payment, shipping or fulfilment partners, detection works well. Pure consultancy relationships generally cannot be identified this way.
10Can I find competitor customers who might become partners instead?
Yes. The same detection identifies companies running complementary tools rather than competing ones, which is how partnerships teams find integration targets, co-sell opportunities and the agencies already serving your ideal customers.
11How do I build a sales battlecard from competitor data?
Start with their install base by segment, add the tools their customers run alongside, and note where coverage thins. That gives reps the objections to expect and the accounts most open to switching.
12Will a competitor know I'm analysing their customer base?
No. Detection reads publicly available website information the same way any browser does. Nothing is requested from the competitor, and no notification reaches them or the companies appearing in your results.
13How much does customer and competitor analysis software cost?
Costs vary by database access, seats and export volume, and typically sit well below a single analyst hire. TAMI includes a free account, so you can name a rival and find competitor customers before paying.

Stop guessing who they sell to

Pick a competitor, see the companies running their product, and take the list with you.
