I don't yet have a case study for this service, however the client gave me a great recommendation on Linked In:
Rachel sat down with both myself and a fellow co-founder and immediately got to the crux of where we had been going wrong with our marketing strategy. She was both informative and friendly and had lots of suggestions for different tactics we could try as a start-up with limited funds. By being able to understand the market we operate in and how our service would fit into it, Rachel was able to give us some great ideas for the future which we will definitely action. I really hope to continue working with Rachel into the future.
