The Economics of Category Design: Switching Costs and Primacy

The two effects that drive category economics

The economics of a created category are dominated by two effects. The first is the switching cost the buyer pays to leave the category leader. Switching costs in a B2B SaaS context are not just the cost of the new license; they are the cost of the integration, the training, the data migration, the process change, and the political cost of explaining to the leadership team why the previous choice was wrong. The sum is typically three to five times the license cost, and it is paid by the buyer, not by the vendor — which means the vendor who has the incumbent position has a structural pricing power advantage that the buyer cannot easily dislodge.

The second is the primacy effect: the buyer’s memory is biased toward the first vendor in a category. The primacy effect is well-documented in the consumer-behavior literature (Murphy, 2007; Shaw, 2014) and has been replicated in B2B contexts. The category leader, having been first, has a memory advantage that the second vendor cannot easily overcome — even if the second vendor has a better product. The advantage compounds: every additional buyer who adopts the category leader reinforces the primacy effect for the next buyer.

Why the effects compound

The two effects compound because they operate on different time horizons. The switching cost is a per-buyer effect: each buyer pays the switching cost at the moment of the next purchase decision, and the sum of all buyers’ switching costs is the vendor’s pricing power. The primacy effect is a per-category effect: every new buyer entering the category inherits the memory of the category leader, and the cumulative memory of the category leader is the vendor’s position in the next buyer’s consideration set.

The compounding is what makes category design a five-year play. The first year, the company is the only vendor in the category; the switching cost is the company’s structural advantage, and the primacy effect is the company’s structural position. The second year, the company has a 60–80% market share, and the first competitor enters; the switching cost is still the company’s structural advantage, and the primacy effect is still the company’s structural position. The third year, the company has a 50–70% market share, and the second and third competitors enter; the switching cost is still the company’s structural advantage, but the primacy effect is starting to be diluted. The fourth and fifth years are the years the company’s share stabilizes — the switching cost is mature, the primacy effect has been diluted, and the company’s share is the company’s share for the next decade.

The window for category design is the window in which the company is the only vendor or the dominant vendor. After the second competitor enters, the window closes. A category leader that has not consolidated the position by the end of the third year is going to be a 40% share vendor for the next decade, not a 60% share vendor. The third year is the year the operating decisions are made.

When category design is the wrong move

Category design is the wrong move when the company does not have a real point of view. A category that the company has to defend with adjectives is a category the buyer will not remember. The category point of view has to be a point of view the company can defend against the buyer’s likely counter-narrative, the competitor’s likely response, and the analyst’s likely pushback. A point of view that cannot be defended is not a point of view; it is a positioning that has not been earned.

Category design is the wrong move when the adjacent category is closed. If the company is competing in an adjacent category that is already locked-in by an incumbent, the right move is to enter the category and compete on a sub-axis, not to design a new category that competes with the closed category. The buyer in a closed category is not looking for a new category; the buyer is looking for a reason to switch, and a new category is not a reason to switch.

Category design is the wrong move when the company does not have the operating cadence to support the design. A category design without a six-month launch sequence, a press list, an analyst relations program, and a category consortium is a slide deck. The category point of view is the artifact; the launch sequence is the work. A company that does not have the operating cadence is going to produce a category book that the press reads once and forgets.

The five-year operating cadence

The operating cadence for category design is a five-year cadence, with the operating decisions made in the first six months and the operating outcomes measured at the three-year and five-year marks. The first six months are the launch: the category book, the press list, the analyst relations program, the category consortium. The first year is the consolidation: the category book becomes the public artifact, the press list is producing placements, the analyst relations program is producing reports, the category consortium is producing peer companies.

The second and third years are the year-on-year reinforcement: the category book is updated annually, the press list is producing placements at a steady cadence, the analyst relations program is producing reports at the major firms, the category consortium is producing peer companies. The third-year review is the year the operating decisions are made: is the company in the position it planned to be in, and if not, what is the response?

The fourth and fifth years are the year-on-year compounding: the category book is the public artifact, the press list is the press list, the analyst relations program is the program, the category consortium is the consortium. The fifth-year review is the year the company decides whether to continue the category design (and consolidate the position) or to shift the operating model (and accept the dilution). The decision is a five-year decision, not a one-year decision.
