What is it like to have Mark Cuban as an investor in your start up? originally appeared on Quora: The best answer to any question.

Answer by John Dick, startup CEO, on Quora:

This is an easy one to answer. Mark got involved in our company just over three years ago and has been a greater asset than I could have imagined. The PR boost we received from the initial announcement would have been worth the price of admission, but that was nothing. When I need advice or help, his responsiveness is unbelievable, and I'm not being hyperbolic. I literally can't figure out how he is so accessible, considering I'm one of countless people bombarding his email on a daily basis. I'm careful not to abuse it because I don't get the sense he suffers pains in the ass very lightly. He knows exactly what he can do for companies like ours: key introductions, killer quotes to reporters, an occasional retweet that gets our content in front of five million people, and solid product and business model ideas. I have to be thoughtful about when I enlist his help and when I don't.

One thing I didn't expect was the number of people who would reach out to me, asking for an intro to Mark. It happens almost once a week. Can you send him my pitch deck? Will you ask him to speak at my event? Will you get him to try my product? It's pretty wild. But it also makes me sympathize with him. If I'm getting this many asks, how many do you think he gets? I've forwarded only one of those requests in three years.

There's a lot about Mark as a shareholder/adviser that is spot-on with his public persona. He's no bullshit. He can get a strong point of view across in a five-word email. He's very opinionated and has lots of ideas. There's no shortage of ego. I haven't pissed him off, as far as I know, and I'd never want to. I've never slapped him on the back, called him by a nickname, or drank beers with him at a basketball game. Unlike some of my investors, we're not friends, not because we couldn't be, but because we don't have time. I have to stay on my toes. It's still business.

Given all of that, he's cool as hell. He lets us write satirical press releases about him and run polls about whether he would beat Donald Trump in a campaign. He knows that what we're trying to do is really hard and doesn't lose patience.

Our company is very lucky to have him on board.
