I might be of some help to you in finding a sustainable business model.
For about a week now, I've been at home in Santa Barbara in the cross hairs downwind of a very large wildfire. If there is a blessing in this, It's that it led me to windy.com, for reasons you can imagine.
I saw your posts and a few others on the business model quest and have a few sustainable directions to offer (with a fun backstory as to how the idea presented itself).
Here's my profile . What's not there is the surfing, sailing, hang gliding stuff... so I'm also personally blown away by the project.
