What Stonebridge says it buys
Read from Stonebridge’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.
| Maximum revenue it states | $200m1 |
| Transaction types | Add-on2 |
| Founded | 19864 |
| People listed on its team page | 173 |

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. Stonebridge 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 Stonebridge to consider any particular business, and nothing on this page is represented as being for sale.
