Customer Acquisition

Customer acquisition — how a business finds and converts new customers, and at what cost — recurs across Kyle’s notes as a competitive-advantage lens. In the Berkshire Hathaway Annual Letters, Warren Buffett discusses GEICO’s acquisition economics: as both Berkshire and its competitors step up advertising, inquiries per ad fall (diminishing returns and rising media rates), but a steadily improving closure ratio keeps GEICO’s cost of new business below the industry’s. The durable edge is in renewal economics — “the lowest among broad-based national auto insurers” — so “others may copy our model, but they will be unable to replicate our economics.” Kyle tags this passage with both CAC and Customer Acquisition.

The same cost dynamic frames Product Led Growth (PLG). Kyle’s notes cite ProfitWell research that CAC has risen ~50–65% over five years as traditional marketing and sales channels saturate — and that freemium businesses see CAC rise only ~25%, making product-led, word of mouth-driven acquisition a structural advantage. In The Hits Business - Research, Kyle attributes A24’s success to its understanding of “internet culture, fandom, and customer acquisition,” connecting the theme to Memetics.
