In the past year, Dave and I have been asked for tips from lots of hardware entrepreneurs, just starting out. No one is ever an expert, but we now have some real experience in this domain and love to share our successes, failures, and the key takeaways those experiences provide.
Marc Barros, an awesome guy and founder of camera company Contour, has been organizing Hardware Workshops to share (sometimes hard-fought) knowledge on what it’s like – and what it takes – to run a hardware startup company. He asked Dave and I to talk about some basic numbers for a hardware company – how much to charge for your product, how to pay a factory, and so forth.
The presentation went well so we decided to share the slides publicly. Hope you find it useful. Questions and comments always welcome.
Jeevan's Thoughts 
A fascinating discussion is definitely worth comment. There’s no doubt
that that you need to publish more on this subject, it might not be
a taboo subject but usually people do not talk about these subjects.
To the next! Cheers!!
