realbuzz charity reviews
We have been scaling up our portfolio of events with realbuzz over the last couple of years, allowing us to internationalise our offering to supporters, without lots of administration. This has allowed us to more easily stay at the forefront of the boom in the running market and stay operationally efficient in this space, especially given the impact of cost-of-living on the peer-to-peer fundraising market.
