The Mathematical Cost of Winning

I submitted the grades for my class, and suddenly found myself a bit idle. So it’s time for more things you already knew proven with math you long-ago forgot. This was supposed to be a mere bagatelle of a post, something to occupy an idle Friday afternoon. And it would have been if the distribution […]

Boiling Frogs

I was responding to a pitch this week. Stellar team, big market, demonstrated customer need. I wasn’t going to invest, despite all that. I wrote: “not the kind of thing I invest in.” I’ve written this thousands of times in my life. But I knew that wasn’t really the reason, so I erased it. I […]

Managing Technological Innovation: Industry Analysis

My short post a few weeks ago on one of Schumpeter’s ideas lightly suggested you could derive most of modern business strategy from that one idea. I suppose this might technically be true if you are a genius with a lot of extra time, but why reinvent the wheel? Last week I taught my class at […]

Schumpeter on Strategy

It’s Friday and I’m procrastinating, so here you go. Let’s talk about Joseph Schumpeter. Good old John Joseph Jingleheimer Schumpeter, as he wasn’t called. Schumpeter once wrote in his diary that he aspired to be the greatest economist, horseman, and lover in the world1. I can imagine the women and horses edging away nervously. Luckily […]

Why do VCs insist on only investing in high-risk, high-return companies?

Sorry this is so short. It’s an interesting topic that I don’t have time right now to do justice. Last week I updated my “am I going to run out of money before I die” spreadsheet, as I’ve been doing every January for ten years. I need to do this because, aside from the paltry […]

iTunes Case: Technological Innovation

Ralph Waldo Emerson reportedly once said “If a man can…make a better mouse trap than his neighbors, though he builds his house in the woods, the world will make a beaten path to his door.”1 Every engineer fervently wishes this were true. It is not. The success of any interesting product is not just a function of […]

iTunes and the Basis of Competition in the MP3 Player Market

CC-BY. PDF here. iTunes and the Basis of Competition in the MP3 Player Market “It’s official: the only thing more popular than MP3 is sex.” So said Rolling Stone magazine in 19991: Virtually unheard of a year ago, MP3—short for MPEG 1 Layer 3—is an audio-coding technology that allows digital music files from CDs or other […]

The Complected Bird

I saw Bill Janeway speak at Columbia the other night. One of the things he said was “pessimists don’t make good VCs.” A truism. This Summer, talking to a younger colleague about the pace and direction of technological innovation I said there was less potentially society-changing technology today than at any other point in the […]

Zipcar Fundraising Breakdown

Thank you to Tom Eisenmann of HBS, who gave valuable feedback on a couple of iterations of this. I teach entrepreneurship at Columbia University. We devote the second-to-last class to a Harvard Business School case study about the early years of Zipcar. It’s a good case and we can review most of what we learned through […]
