Most founders think a moat is something you build with money or time: more scale, more users, a bigger brand. Helmer's seven powers each describe a real, durable advantage, but six of them take years to accrue. Counter-positioning is different. It is available on day one, and only to the newcomer.
The mechanism is structural, not tactical. You pick a business model that is better for the customer, then you check one thing: would the incumbent suffer if they adopted the same model? If the answer is yes, you have power. Not because they cannot copy you, but because they will choose not to. Their existing revenue, channel, or cost structure makes the new model self-harm. The classic illustration is Netflix versus Blockbuster: the late-fee economics that funded Blockbuster's stores were exactly what made a subscription, no-late-fee model something Blockbuster could not embrace without burning down its own income statement.
This is why Helmer pairs every power with two parts, a benefit and a barrier, what he calls the to-be-or-not-to-be test. Operational excellence is not a barrier; competitors copy it. A business model the incumbent is structurally unwilling to match is a barrier. Counter-positioning, in one line: win by being something the leader cannot afford to become.
