I think its worth pointing out how important it is having that one investor willing to fund companies and move them to a startup neighborhood.
Here in Jacksonville, FL we've seen 2-3 different attempts to create innovation districts downtown in the last five years, always led by entrepreneurial activists leveraging tax grants and "if you build it they will come" mentality. One collapsed after building an incubator and funding only small consumer products instead of the startups they promised and wasting a huge amount of money on overhead. One never got off the ground. Another launched to much fanfare and then went silent. I've been told political leadership are pretty sick and tired of hearing how entrepreneurship is going to save everyone.
You get these excited people wanting to make a difference so they follow the playbook but without the key players and it fails. But I get shade for being the one saying not to do it because its wasting goodwill for when a real opportunity comes along, everyone who could act has already been burned by false promises based on little more than hope.
