Peter Matthaei wrote down some thoughts on failure, startups, and product development in ALL THE USE CASES. He makes some good points, like this one:

Every great company started by being great at solving just a single problem. Quite often, a very humble one. But they solved that one problem incredibly well, picked up momentum, and with large doses of relentless ambition, good timing, vision and luck kept on going.

Dropbox is, of course, the poster child for this line of thinking. One of my favorite Quora answers is still Michael Wolfe’s response to Why is Dropbox more popular than other programs with similar functionality?:

“But,” you may ask, “so much more you could do! What about task management, calendaring, customized dashboards, virtual white boarding. More than just folders and files!”

No, shut up. People don’t use that crap. They just want a folder. A folder that syncs.

I would add that I think the problem with most startups is not necessarily that they’re trying to solve too many problems; it’s that they’re trying to provide solutions to problems that don’t exist. I love this quote from Pragmatic Marketing in their post Who Needs Product Management?:

It is vastly easier to identify market problems and solve them with technology than it is to find buyers for
your existing technology.

My thesis continues to be that the single biggest cause of startup failure is focusing on finding buyers for cool technology, as opposed to identifying (and fully understanding) market problems first.
