Resolver

Resolver was founded by a former Which? executive with extensive experience in the consumer choices space. Its easy-to-use tool helps consumers draft complaint letters, and escalates their complaint to an ombudsman or formal complaints body if needed. Resolver has worked with companies and institutions such as British Airways, Shell and RBS, and has been endorsed by Money Saving Expert, which lends it considerable credibility.

Its popularity among consumers and companies alike has allowed Resolver to become the UK's biggest consumer complaints site. Expanding their team and client base will allow the company to scale further.
