1. This is a superb essay delineating the attributes of a fast-growth, all-or-nothing type of startup. No surprise here. Who besides pg has had the depth and breadth of quality first-hand experience with such ventures over such a sustained period and in such an explosive context as that of recent years? He has here given us a classic analysis of the prototypical, Google-style startup.
2. I think the idea of a startup should not be so narrowly defined, however, and the big reason is this: many founders set out to build ventures that are tech-based, innovative, aimed at winning key niches via hoped-for rapid growth and scaling, positioned for outside funding as suited to their needs, and aimed at liquidity via capital gains as the primary ROI for their efforts . . . but who also place a huge premium on minimizing dilution and maximizing founder control. These are the independents. The ones who, by design, want to defer or even avoid VC funding so as to build their ventures on their own timing and on their own terms. Now this is not the Google startup model. It is, in a sense, its opposite. But it is not the model of a small business either. It is just a different type of startup.
3. The trend over this past decade has moved decidedly toward greater founder independence in the startup world. Back in the bubble days, as a founder, you had very little information available to learn how startups worked, you often had heavy capital needs (e.g., $2M to $4M) right up front to do such things as build your own server banks, and you would almost certainly have little leverage by which to minimize dilution or loss of control at the time of first funding. Today, this has completely flipped. Vast resources are extant teaching founders how startups work. Initial capital needs are often minimal. And it is relatively easy to get reasonable funding on founder-friendly terms. What this means is that, today more than ever, the independent-style startup is more open to founders than ever before.
4. Given the above, it seems to me that this is not the time to say that the only style of startup worthy of the name is that of the super-rapid-growth type. The rapid-growth type may be more glamorous by far but it really defines only the tip of the startup world. Beneath it is a vast world offering incredible opportunities to founders who want more control over the timing, scale, and management of their ventures and who seek to realize gains and manage risks accordingly.
