A lot of great ideas here from Simon Sinek. As much about Sales as it is about Vision.
This is a great site, I highly recommend it. MMM was an initiative that ran from 2004 until 2014. Its goal was to transform the way people working with arts and culture used their resources to create great experiences which had deep public value.
If you haven’t come accross the Suddes Group before then this site is a must visit. Lots of great insights and tools. Yes, very tailored to an American context but still invaluable. I had the good fortune to attend his training workshop and his ideas have been invaluable.
If you’re really interested in the nuts and bolts of start-ups then Donncha’s site is a great place to start. He was one of my trainers and his advice and support was always excellent. His site is well worth a browse.
