He actually didn't even cover one of the worst parts about the whole process - fake buyers who just want to steal your tech. I was working at a startup with a ground breaking product no one had released before, we had shipped hundreds of prototypes and gotten good reviews and had plenty of orders, but board redesigns and setting up a factory assembly line for the production models was eating into our cash and runway.…
I was contacted by someone at CrowdStrike (yep, I'm naming those bastards), who wanted to setup a meeting about a potential partnership. We had a chat, and then had a long meeting with several CrowdStrike people, including some software engineers.
I demo'd our product, and all the way through, the devs were asking these really detailed questions - they wanted to know precisely how everything worked.
In my naivety, I assumed this was all in good faith, despite alarm bells starting to ring with some of the questions.
Anyway, all through the demo they went on about how great the product was, and sucked me dry of information - and then ghosted me. I reached out by email a few times after, and every time all I got was "yeah, we're busy, so...".
I learned a valuable lesson that day: don't assume others are as principled as you.
