I am 20 and moving to SF in a month . To help people be more productive I am building a self management software tool for startup employees, something you can use alone or in group with goals, feedback, and psychometric stuff. I am 4 month into code and still need 2-3 more months to make something I can sell (at like 5$/user/month) or get free users. Originally I am from France so I only have a 3 months window once in the US to take of and raise seeds to get my visa (otherwise I can maybe get married or I am screwed and come back crying at my mother's). Do you have any advice ? Things I should do ? People I should talk to ? Startegies I should use ?
