Tracy Britt Cool

Tracy Britt Cool is a former senior executive at Berkshire Hathaway and today a prominent advocate for Warren Buffett's brand of patient, owner-oriented investing. Raised on a Kansas farm with a pronounced early aptitude for math—by age 15 she was president of the local farmers market—she wrote directly to Buffett as a 24-year-old MBA student and was hired in 2009 as financial assistant to the chairman, a title Buffett invented for her. She quickly became one of his most trusted lieutenants, grouped with Todd Combs and Ted Weschler as "the three T's," and went on to chair several Berkshire subsidiaries and serve as CEO of Pampered Chef.

From the Inner Circle to Independence

Britt Cool's unusual access gave her a firsthand education in Berkshire's method: buy understandable businesses with durable economic moats, stay strictly within your circle of competence, and insist on a margin of safety between price and intrinsic value. In early 2020 she left Berkshire—rare for a senior executive—and, with former CFO Brian Humphrey, founded Kanbrick, a long-term holding company whose name fuses "Kansas" with "brick," signaling businesses built brick by brick.

Teaching Financial Independence

Kanbrick's first deal was a stake in Thirty-One Gifts, and its "Build with Kanbrick" program mentors the owners of thousands of mid-sized family businesses whose annual profits fall between $10 million and $50 million—exactly the size Warren Buffett used to buy before Berkshire grew too large. Her broader mission is financial independence: teaching non-professionals to read a business, judge its intrinsic value, and resist the crowd, so that ownership becomes a source of security rather than anxiety.

What distinguishes Britt Cool is her commitment to education. Through Kanbrick's "Build with Kanbrick" program and a widely read annual letter written in the Buffett tradition, she coaches owners of mid-sized family businesses on capital allocation, governance, and the psychological discipline of long-term holding. Her core message is financial independence: that understanding how good businesses actually work is a learnable skill, not a mystery reserved for Wall Street.

She is candid that Kanbrick is "not Berkshire 2.0" but a different vehicle applying the same principles to smaller, overlooked companies that a $600 billion Berkshire can no longer buy. In this she channels Buffett's own early career, when he acquired modest businesses with the same rigor he later applied at scale.

What Investors Can Learn

During her Berkshire years she chaired several subsidiaries and ran Pampered Chef, learning how capital allocation and culture compound inside an operating business rather than merely across a portfolio. That operator's perspective now shapes Kanbrick, where she and Humphrey take an active hand in the companies they own rather than leaving managers entirely alone.

Britt Cool illustrates that the value framework survives translation across eras and company sizes. Her career teaches three lessons: that a margin of safety protects both balance sheets and operating plans; that long-term holding of well-chosen compounders beats a three-year sprint; and that intrinsic value—not the market quotation—is the anchor. For serious investors, she is a reminder that the most durable edge is often the willingness to keep learning, stay within one's circle of competence, and educate the next generation of owners.
