reverse acquihire
In plain wordsA deal in which a big tech company hires a start-up's founders and top staff and pays to license its technology, without buying the company itself.
A transaction in which a large company hires the founders and key staff of a start-up and pays a large, usually non-exclusive licensing fee for its technology without acquiring the company, which continues with its remaining employees while investors are repaid from the fee. The structure gives acquirers scarce AI talent quickly while avoiding the merger review and antitrust scrutiny a full acquisition would attract. Examples include Microsoft's deal with Inflection AI (March 2024, about US$650 million), Amazon's with Adept (June 2024) and Covariant (August 2024), Google's with Character.AI (August 2024, about US$2.7 billion) and Windsurf (July 2025, US$2.4 billion), and Meta's purchase of 49% of Scale AI for about US$14–15 billion while hiring its chief executive (June 2025). Critics say such deals hollow out start-ups and leave remaining staff stranded.
It wasn't an acquisition, it was a reverse acquihire: Google got the founders, and the rest of us got the empty office.
Origin
An inversion of 'acqui-hire' (2005), buying a company mainly for its staff. Used in technology and venture-capital commentary from 2024 and widespread by mid-2025, after Google's Windsurf deal.
Usage note
Competition authorities have scrutinized the structure; the UK Competition and Markets Authority treated Microsoft's Inflection deal as a merger but cleared it in September 2024. Earliest use of the phrase not established.
