Stated investment criteria
What Haddington Ventures says it buys
Read from Haddington Ventures’s own website in August 2026. This is what the firm says it buys, not what anyone has recorded it buying, and figures are shown in the currency the firm itself used - nothing here is converted. Every line links to the page it was read from.
Sources
A stated mandate is a firm’s description of itself and was true of the page on the day it was read; firms widen and narrow what they will look at without updating the site. Haddington Ventures states that it takes majority or outright ownership. The team figure counts the people the firm shows on one team page, so it is a floor rather than a headcount: firms that split their team across tabs or load it in pages will read low. Nothing here is a commitment by Haddington Ventures to consider any particular business, and nothing on this page is represented as being for sale.
