Ask HN: [UK startups] has anyone worked with Growth Accelerator?

http://www.growthaccelerator.com/

Their self-description is "GrowthAccelerator is a government-backed service that helps ambitious businesses to grow through coaching, workshops, masterclasses and match funding. We can help you with business development, leadership and management training, access to finance and innovation."

They don't focus specifically on tech or startups -- their "success stories" page lists a number of companies in a range of industries, from engineering to insurance to restaurants. But they offer coaching and apparently can do investor introductions at some level.

OTOH they do charge for their services, which is a bit of a red flag for me.

So, has anyone here used them?
