>Paul : The biggest one is made-up ideas. The best startups come from personal experience. It was something you or someone you know needed. Occasionally, I’ll ask a company, “Why do you think is a good idea?” And they’ll say, “Oh, I read an article in TechCrunch.” You have to understand it at a deep level. It can’t just be something you read.
I also like people who get things done. If you’ve been working on your startup for two years and have nothing to show, that’s a pretty bad sign. I’ve discovered that most people are really good at finding obstacles. I don’t fund these people.
One thing I've learned, over five years plus of developing Inventions, Pitches, and the occasional Prototype, is that there's a really big realization that Angel Investors / PE-type Investors don't want small businesses to figure out:
If your idea is good, you can obtain a patent, and afford to take a loan <$50,000 to go from "Prototype-to-Trade Show Ready" then you don't need Investors. You don't need "wisdom and guidance" aiming for a quick ramp-up and exit. You don't need to think in Quarterly Capitalism terms. And, most importantly, you don't need to dilute your control whatsoever[1].
For a while I've caught some whiffs that the Investing Realm is quite a bit more "Me Too" risk averse than often portrayed. Very similar to the Music Industry. Labels don't want interesting life story pieces, they want bubblegum they can market to kids with some discretionary money to burn. Thus, I take a lot of the recent "Start Up" culture with a grain of salt, because the time, effort, and study it takes to create a genuinely valuable idea basically points to starting a "Traditional Small Business" moreso than any super-duper-evolution-in-funding-or-growth. YMMV of course.
[1] It does help to study both success stories, failures, and Public Slap Fights (Cruise, Otto); while I've solicited in the past, I've cooled to the idea and instead plan to go my own Patent-Prototype-Promote business model.
