Frequently asked questions
What is WhoBoughtWho?
WhoBoughtWho is a free reference for how businesses actually change hands: a directory of marketplaces, brokers, newsletters, tools, and communities for buying and selling businesses, cross-linked with a public record of real company acquisitions (who acquired whom, when, and for how much). It's built for early- and mid-career professionals getting into M&A, private equity, and search funds, not just people already deep in the industry.
Is WhoBoughtWho free to use?
Yes. Browsing the directory and the acquisition history is free, with no paywall or subscription — the goal is to be a comprehensive, open reference for anyone researching business acquisitions.
How is the data sourced?
Directory listings are researched and verified against each company's own website. The acquisition history is sourced from public records (primarily Wikipedia's maintained acquisition-history pages), with a link back to the original source on every entry.
How do I get my marketplace, broker, or newsletter listed?
The directory is actively growing. If you run a resource for business acquisitions that isn't listed yet, reach out and we'll review it for inclusion.
