Fred Wilson writes why seed investing is less risky than later stage investing:
My basic point is in seed/early stage investing you ante a little, see your cards, decide if you want to invest more in your hand, see some more cards, etc, etc. You get to stage your risk capital as the investment shows itself to you over a number of years. You can manage all kinds of risk this way; management risk, valuation risk, technology risk; and market risk. Classic later stage investors want to be in the last venture round and in that scenario, you are putting all your chips on the table before you’ve really seen your cards.
Later stage investors can’t impact the development of the company. They have to accept the direction that has been put in place before they came in. We typically invest in pre-revenue companies. Usually they have the technology platform in place and in most cases, they have launched something with some success. But getting the business model and market entry strategy (the angle of attack) right is key.
