Bluehat UK managing director Tim Shepley said: "Clients want to know that their events company will fully understand their needs and provide the right solution for their specific teams. Adding Catalyst’s experience to our own gives us this fuller understanding."
The news comes after Catalyst UK went into voluntary administration, terminating the contracts of its seven members of staff.
Former Catalyst UK account director Charlotte Cornwallis has now been appointed head of sales for Catalyst UK.
Cornwallis said: "Clients can now benefit from the creative strength of Catalyst working together with Bluehat. We expect to offer clients the benefit of our pooled experience."
Former event director Fiona Craven has also been appointed as head of events for Catalyst UK.
She said: "Working alongside Bluehat’s events team means that together we can deliver even stronger solutions for clients who take team-building events seriously."
