Bob Bean
Transnetyx, Inc.

“... we are fortunate, very fortunate, to have found Thompson Street Partners as a capital partner for our company. I would recommend Thompson Street to other business owners if what they’re looking for is a true partnership to grow their business.”

Randy Heffernan

“... they back up what they say, which has been fantastic. It’s easy to sort of promise help but it’s another thing to really deliver. So I think that really stands out and it makes Thompson Street much more of a partner than sort of merely an investor.”

Don Potter
Savillex Corporation

“... all the people that we met from the Thompson Street team were very straightforward, easy to get to know and do business with – very approachable, friendly people ...”
