Building change together

More Onion is more than just an agency – we are committed activists and fundraisers with deep strategic, creative and technical expertise.

We specialise in supporter and donor journeys, from recruitment via high ROI advertising to development and retention through engagement actions.

We’re also known for Impact Stack - our powerful mobilisation and fundraising platform - and our professional training sessions.

Our team is based across Europe, especially in the UK and in our central office in Vienna.

What clients say

  • More Onion are just incredible. They’re brilliant at challenging you, steering the conversation and taking a pragmatic approach that always puts the audience first.

    Josie Isherwood Senior Direct Marketing Manager at Shelter

  • We've all learned loads working with More Onion. The creative ideation sessions were beneficial for us internally as well as for the outputs themselves.

    Amy Jarvis Head of Individual Giving, St Mungo's

  • It’s been brilliant to work with you! It feels like we’ve come such a long way and it wouldn’t have been possible without all your expertise, knowledge and fantastic training.

    Georgia Romeril Senior Marketing and Engagement Manager at Missing People

  • I've worked with agencies who are much more 'just do what we say' without really backing that up or sharing expertise. Working with More Onion I always felt we were learning and supported to develop our own skills.

    Sally Rose McCormack Digital Marketing Executive, Concern Worldwide

  • More Onion were able to give us clear examples, direction and clarity of thought about how we could take our project forward. The session was designed completely in the context of where we are as an organisation.

    David Bridson Head of Campaigns and Research, YMCA

  • The team reacted quickly to questions or problems, gave good advice and managed the acquisition and supporter engagement pathway effectively so we didn’t need to think about it. The More Onion team are professional, flexible, and great to work with on digital mobilisation.

    Rebecca Hubbard Programme Director Our Fish

  • It is always a real pleasure working with More Onion. They're the absolute definition of how an agency should work: expert people who you really feel are on your side.

    Eve Jackson Activism campaigns manager, Mencap

  • Working with the team at More Onion over the past couple of years has been both effective and instructive.

    Dave Beynon, Head of Digital Marketing, Compassion in World Farming

  • The team reacted quickly to questions or problems, gave good advice and managed the acquisition and supporter engagement pathway effectively so we didn’t need to think about it ... great to work with on digital mobilisation.
