There are tons and tons of courses and videos about high-tech entrepreneurship. In 2013, the star was probably Peter Thiel. In 2014, it seems to be Sam Altman, President of Ycombintor with his How to Start a Startup The first 2 lectures have been very good with a focus on the ingredients a start-up requires:
1- an idea,
2- a product,
3- a team,
4- an execution.
Altman added in a typical American manner that hopefully you do not execute the team in step 4. You can find the videos on the web site How to Start a Startup, and also the full text of the lectures here:
