An interesting brick and mortar example in the Bay Area was Fry's electronics. When they started, they grossly undercut all of the electronics brick and mortar stores and priced more like the distributors did rather than the stores. As a result their business grew quickly and the other stores were unable to compete and went out of business. Then with the market to themselves they raised their prices to increase their…
Agreed, but phrasing it in the “here’s what changed that most people don’t understand” language that VCs love: “in the age of cheap money, scale is not a defensive moat” When Fry’s was founded, it was so prohibitively difficult to get the funding to scale to their size, that competition was thwarted by lack of investment. Now? The trick is public knowledge; the funds are cheaply available to anyone able to scale a co…
Knowing that you're the attacker and they're the defender and that most consumer markets favor the incumbent, the investor won't hand over their capital unless you can show that you've already started to take their market. And then once you have shown that you're taking a fat incumbent's market, they're happy to fork over tons because they know that every other investor's reasoning will be the same, and nobody will want to attack an incumbent that can just drop prices to fend off a challenger.
BTW, Google decided to buck the outside investors in exactly this example, funding GFiber internally. It played out basically exactly as the scenario above - the incumbents rolled out gigabit cable/fiber at competitive prices in precisely those markets GFiber was threatening, preventing them from making serious inroads. There were a bunch of other factors (like regulatory issues and the difficulty of scaling last-mile telecom), but after recent examples like that investors would rather find virgin territory rather than fight price wars in large existing markets.
(IMHO, this is one thing wrong with American capitalism today, as our system relies on cutthroat competition and aggressive risk-taking behavior by investors to get good deals to consumers.)
