I have a company I started with 2 university professors in the geospatial analytics space and as I work on building out the tech I am increasingly anxious about spending since we're pre-revenue and it's all out of my pocket for now. This Microsoft for Startups is appealing to me. Anyone know of any similar programs I should look into?
