Mash was founded as a promotional staffing agency in 2004. We began by servicing experiential marketing agencies – recruiting, training and managing excellent staff to be at the forefront of their campaigns. While we still work closely with many leading agencies, we now also work directly with brands – providing staff to engage with their target audiences through a variety of marketing initiatives.


We provide promotional staff for a number of global brands directly, including BMW, MINI, Waitrose, Lavazza Coffee and Chelsea Football Club. We also work with experiential agencies. We staff ongoing campaigns such as Co-Op for Fresh and Lidl for CSM, major one-off activations such as Samsung Studios for Cheil, and lots of tactical projects for Initials, The Marketing Store, iris and many more.


We have over 15 years experience in promotional staffing across a wide range of marketing activity – from giving out samples at train stations where efficiency and accurate data collection is key, to guiding audiences through in-depth immersive brand experiences where brand training, people skills and enthusiasm matter most. We can also help with the extra bits – like product storage, logistics and staff uniforms.


We have over 4,000 experienced and committed promotional staff on our book, based across the UK and Ireland. Every prospective Masher is interviewed by our talent team before earning their place, and all our staff work regularly for our clients. Mash is a strong and successful community, and our brilliant talent team make sure every member of staff feels part of something special.

Case Studies



With a huge amount of promotional staffing experience on many live campaigns for global brands, Mash is a leading promotional staffing agency in the UK. We provide promotional staff to work at the full spectrum of live events, including sports events, festivals, experiential campaigns, roadshows and product launches.

We provide promo staff in London and right across the UK. Our book includes Brand Ambassadors, Event Managers and other skilled promotional staff such as face painters, gymnasts and footballers. Our promo staff work for different brands across all industry sectors – including technology, automotive, sports, consumer electronics and FMCG. We are proud to have built many long-lasting relationships with our clients, and thank them for the part they’ve played in making Mash such a successful promotional staffing agency.


There are relatively few promo agencies in London. Our base at London Bridge is welcomed by most of our clients who prefer to work with a promotional staffing agency in London. However, we do not just provide promotional staff in London, but manage a book of 4,000 high quality promo staff who are based right across the UK.

We regularly staff campaigns in Bristol, Birmingham, Manchester, Leeds, Edinburgh and many more towns and cities, as well as across Northern and southern Ireland. We are proud to be a promo staffing agency who can offer 100% coverage across the UK and Ireland, ensuring that we can always staff major UK-wide promotional staffing campaigns.


Since 2004, we have been providing promotional staff for many memorable experiential roadshows and tours. This usually involves one or two campaign Event Managers working with regional Brand Ambassadors in each location. We support our clients in a range of different ways – from simply providing great staff, to helping with uniform, logistics, and permits.

Our extensive experience in this area of promotional event staffing makes us an ideal partner for clients looking to implement a large-scale promotional roadshow activity.


We work with a number of innovative tech brands, providing promotional staffing for launch activities, PR stunts, and long-running experiential demo campaigns – working at events, in shopping centres, and supporting in-store activations for brands.

We select our promotional staff for technology campaigns based on their technology experience and passion for the product – ensuring they represent our client’s brands with authenticity and enthusiasm.


Our experience in large-scale sampling activity includes working with some of the biggest and best-loved FMCG brands – from soft drinks to snacks, chocolate, coffee and alcohol – helping their products reach a wide audience through quick but memorable consumer interactions.


We work with major sports venues and sponsorship brands, providing promotional staff to help ensure visitors enjoy their day and have a memorable brand experience. We train our promo staff for fan engagement in both the brand they are representing and the sports event taking place. We work with Twickenham Stadium, Chelsea Football Club, at the BMW PGA Championship at Wentworth and Goodwood Festival of Speed.


With summer being the busiest season for promotional staffing, securing exceptional staff for festival work is highly competitive. However, we have an excellent track record in this, and are able to provide high calibre promotional staff at festivals such as the Isle of Wight, Bestival and Reading & Leeds – as well as for specialist festivals like Taste of London – for a range of brands.
