Ooops, I do apologise : ) Would the 3 hour extra timeframe work in our favour or against?
And as others have said - it's a great idea, especially given the shortage of technical talent. The biggest challenge I could see would be whether you can provide enough hours (value) for each startup, while simultaneously working with enough startups to give you the multiple pies you mentioned, and all this on top of a full time job. In any case good luck, and let us know how it goes!
