Serial entrepreneur, B2C + B2B business delivered 10+M$ revenue, ex-Microsoft MVP (hardware), AMA

Hey, PH. I started my business from PH. We build hardware, and software and AI algorithms mostly for audio, but including IoT, App, Wireless and Cloud. Made lots of mistakes since 2014, we did business oriented and consumer oriented business, both went through up-down-up growth curve. So about startup, about business strategy, about marketing, about trade-show, and product-market-fit, especially about hardware, I believe I have lots to share for new entrepreneurs. So just AMA here, I've been with 54 days PH streak, another 54 days could not be a problem. And twitter works too. Glad to help.
