The coming together follows the agencies, both of which were on the hunt for a partner, working with the same holiday sector client, sunshine.co.uk.
In future, both agencies will open up their respective offices to share desk space with the other, giving Bronco a presence in the South West of the UK and 10 Yetis a presence in the Leeds and Yorkshire region.
There will also be an employee exchange programme, with 37 staff employed collectively by the pair.
Andy Barr, co-founder of 10 Yetis, said the move was about offering ‘a more rounded service to clients’.
Of Bronco, he added: ‘Despite thinking we knew a fair chunk about search campaigns and strategies, 10 minutes with their team opened my eyes to how much more we need to learn.’
