Enter any company’s website. Get the companies most likely to want it, ranked by what they have actually bought before, each with its precedent deals. A buyer brief reads the site and quotes it.
Free: 3 new companies a day, the top 3 buyers of each, 3 briefs a day.
By precedent: companies tend to buy what they have bought before. We collected about 4,600 acquisitions by 159 companies from Wikipedia: big acquirers like Google, Microsoft and Cisco, mid-size ones like Stripe, Datadog, Atlassian and PayPal, and buyers found in thousands of company articles. WhoBuys reads your website, writes a short plain description of what you do, and compares it by meaning with every acquired company. Buyers whose past deals are closest rank first.
If one of the 159 buyers in our data acquires your company, the chance it is this one. We calibrated them on 1,583 past deals: when WhoBuys says 10%, that buyer was the real one about 10% of the time. They don’t say whether you will be acquired at all; that depends on things no website shows.
Tested on every acquisition since 2010 in the data, with that deal hidden: the real buyer was ranked first 30% of the time and in the top 5 56% of the time, against 22% for "always name the five busiest buyers" and 3% by chance. Real websites are noisier than those test descriptions, so treat the result as a well-founded shortlist, not a forecast.
Because they buy the most, across almost every category. Below the main ranking, Specialists shows smaller buyers that once bought a company very close to yours, and the buyer brief explains each fit and what could stand in the way.
Our data covers 159 buyers with public acquisition records on Wikipedia; many active acquirers, private ones especially, aren’t there yet. The buyer brief can also name companies your own website mentions as a partner, platform or competitor.
We don’t know, and we never say so. WhoBuys shows strategic fit from public precedents. It is not a rumour, a prediction of a deal or investment advice.
Three new companies a day with their top 3 buyers and specialists, any company someone already checked, and 3 buyer briefs a day. A one-time $0.99 unlocks unlimited checks, all 10 buyers, CSV export and unlimited briefs, forever. No subscription.
Yes: a check reads only the public website, and its result has a shareable page. WhoBuys is independent and not affiliated with any company named. It runs on Contextrie and Bref UI, both open source on GitHub, if you want to build something like it.
