Not to be too cheeky, but this is mostly a list of trends dictated by companies started three or more years ago.
Meaning it's actually "VC Compatible Startup Ideas 2017."
Outside of Developer Tools (I'm a fan!)

Daniel's an investor, so he's casting a net for startups / founding teams he hasn't heard of yet. Content marketing is dealflow 101. That said, if you're a founder in one of these spaces, he has a fantastic reputation, so you should absolutely reach out. He wouldn't have posted it if he wasn't looking for awesome people!
