I first met Mark in 1998 when a VC tried to marry NewHoo with Onelist, and told us that the combination "might be interesting". Pfft! NewHoo and Onelist both went on to successful exits, and Mark's an interesting guy, so I guess it all worked out in the end...
Mark's advice is spot-on for a lot of the web 2.0 companies being launched now. I like Mark's list because it's a little edgier than a lot of the smile-faced spin you see on VC blogs.
Note that Mark himself seems to start companies during down-cycles, and sell them when the market gets hot. Then he goes on vacation for a year or two and waits for the next down-cycle. :)
1. Your idea isn't new. Pick an idea; at least 50 other people have thought of it. Get over your stunning brilliance and realize that execution matters more.
2. Stealth startups suck. You're not working on the Manhattan Project, Einstein. Get something out as quickly as possible and promote the hell out of it.
3. If you don't have scaling problems, you're not growing fast enough.
4. If you're successful, people will try to take advantage of you. Hope that you're in that position, and hope that you're smart enough to not fall for it.
5. People will tell you they know more than you do. If that's really the case, you shouldn't be doing your startup.
6. Your competition will inflate their numbers. Take any startup traffic number and slash it in half. At least.
7. Perfection is the enemy of good enough. Leonardo could paint the Mona Lisa only once. You, Bob Ross, can push a bug release every 5 minutes because you were at least smart enough to do a web app.
8. The size of your startup is not a reflection of your manhood. More employees does not make you more of a man (or woman as the case may be).
9. You don't need business development people. If you're successful, companies will come to you. The deals will still be distractions and not worth doing, but at least you're not spending any effort trying to get them.
10. You have to be wrong in the head to start a company. But we have all the fun.
11. Starting a company will teach you what it's like to be a manic depressive. They, at least, can take medication.
12. Your startup isn't succeeding? You have two options: go home with your tail between your legs or do something about it. What's it going to be?
13. If you don't pay attention to your competition, they will turn out to be geniuses and will crush you. If you do pay attention to them, they will turn out to be idiots and you will have wasted your time. Which would you prefer?
14. Startups are not a democracy. Want a democracy? Go run for class president, Bueller.
15. You're doing a web app, right? This isn't the 1980s. Your crummy, half-assed web app will still be more successful than your competitor's most polished software application.
Update: Only tangentially relevent, but uncov is just too damn funny.
