Pros
The people and charities that raise money on the site are doing some really incredible and inspiring things. It feels good to be a small part of that, helping people.
Cons
Pretty much everything else. Lack of direction, terrible company culture, HR support non-existent, huge staff turnover, infighting, management who are completely ill-suited to their roles and are holding on for as long as they can get away with it, and morale that seems to be plummeting to new lows on a weekly basis make it hard to see how the company will bounce back. US-owners have little to no interest in the company's mission or culture, having bought at an inflated price with their main focus selling software solutions to charities in the UK. Work on innovative and exciting tech to help the charity world has been replaced with stale and mundane tasks, developers are voting with their feet as people have mentioned in other reviews. Most teams are in panic stations with unreasonable goals, and terribly under-resourced for what they are expected to deliver. The result is a really unpleasant blame-culture, that is far removed from what the company used to be like, when inevitably projects are not delivered on time or successfully and when results don't line up with projections. It's really sad what's happened with JustGiving, as prior to the takeover it was a really rewarding place to work. It wasn't without fault for sure, but I'd say it was an above-average tech company with an excellent pool of talented employees. Unfortunately, many of them left and those left behind have been let down badly by the new owners and the individuals they placed in charge in management.
