While bulls argue that large insurance brokers do not heavily participate in personal lines or small commercial markets, BofA counters that years of constant “tuck-in M&A” have created a “snowball effect.” Hundreds of small acquired shops have brought a significant amount of low-complexity, small-ticket business under the umbrellas of large brokers, a vulnerability that is often obscured by subpar public disclosures. Furthermore, even large-case, complex business—which is unlikely to face direct disintermediation—could experience pricing deflation as AI demystifies the insurance markets for sophisticated corporate buyers.
At the Lean FRO, Kim Morrison, a Senior Research Software Engineer, recently ran an experiment that went well beyond our expectations. An AI agent converted zlib, a widely used C compression library embedded in countless systems, to Lean, with minimal human guidance. No special tooling was built. It was Claude, a general-purpose AI, with no special training for theorem proving, out of the box. The workflow had four steps. First, the AI produced a clean, readable Lean implementation of the zlib compression format, including the DEFLATE algorithm at its core. Second, the Lean version passed the library’s existing test suite, confirming behavioral equivalence. Third, key properties were stated and proved, not as tests, but as mathematical theorems. The capstone theorem:
