About the data

Methodology

Everything you need to decide whether to quote a number from this site. Where the rows came from, how each one was decided, and what the data supports.

Where the rows come from

Every row came from a public announcement: a company newsroom, a press release on a wire, or a named trade publication. Each page is saved on the day it is read, so a row can still be checked after the page changes or disappears.

Most rows come from the company itself. Of 1420 rows, 1283 are from a company's own newsroom, its partner directory or its press release. The rest are from named trade press. Anything read off a logo wall, a job posting or a third party list is not published here at all.

Announcements span 2003 to 2026. There is no date window, because a partnership announced in 2019 is still a partnership.

How a row is decided

Software finds candidate announcements. A person decides what each one is and records the sentence it rests on. That sentence appears on the row, so you can read what the decision was made from without leaving the page.

An announcement that does not say what one company supplies to the other is dropped rather than guessed at. Words like marketplace and referral mean something precise in a contract and something loose in a press release, which is why the classification is not automated.

Every row is read a second time by a reader who sees the sentence and the two company names but not the first answer. Rows the two readings disagree on are corrected. Rows whose sentence turns out to establish nothing are removed before publication.

What the data is good for

Looking up a company before you meet it. A company page lists every partner that company has announced, with dates and sources.

Separating a partnership from a purchase. 1091 rows put a product in front of somebody else's customers. 329 are software a company bought to run itself. Both get announced as partnerships, and only the first is counted here.

Seeing how a kind of deal works. Each type page carries the definition, how the money usually moves, and every real example.

Quoting a number you can defend. Every count resolves to rows, and every row resolves to an announcement you can open.

What it is not

It is not a census. It holds partnerships that were announced publicly and that we read. Shares computed from it describe this dataset.

Company pages differ in depth. We read the newsroom of 118 companies. For 14 we found no newsroom, and 18 do not allow automated reading. Every company page says which applies at the top.

12 companies are left out. They are not named anywhere here, including as somebody else's partner. Where one is a partner on a row, the row appears with that partner unnamed, so counts stay right. Any figure this affects says so.

Two publications were reachable and not used. One blocks automated reading. The other serves subscriber articles in full to anyone who asks.

Figures on this page were generated on 2026-08-28. If a row is wrong, tell us which one.
