We have worked with various other suppliers, but Sixfold is the only provider we are currently working with, have done so for a fair while & intend to continue working with – this is because they are flexible, reasonable and deliver an excellent quality of work. To explain:
Flexible & reasonable – we (jointly) had to shift the business model of our arrangement in the run up to the first event. Sixfold responded in a reasonable & flexible manner – exactly what you’d hope for with a long term partner, but not something that always happens.
High quality – courses are bespoke; clients are demanding (and from high calibre companies). We’ve had excellent, excellent feedback from clients.
I’d also say that Sixfold & Andy are reliable – when they say they’ll do something, they will. Always good in a partner!
So, in terms of a reference, I’d have no issues highly recommending Sixfold.
I hope this helps & best of luck with whatever venture that you are intending to partner with them on.
