The firm is co-founded and still actively owned by Thomas Sahlin (Marketing/Sales) and Ulf Synnes (Project Management/Sales), with no parent company, PE, or VC ownership disclosed. Headcount figures and direct revenue disclosure indicate the business operates at a ~200 MSEK annual revenue run-rate.
