Worth knowing: Epic Systems' Cosmos research platform is the structural depth feature most national DS surveys understate for WI.

Epic's healthcare ML investments include substantial Generative AI integration since 2023 (the Epic/Microsoft + Epic/Nuance partnership for clinical documentation AI). Exact Sciences HQ Madison (~$2.5B revenue, the country's largest cancer-detection diagnostic company by molecular volume, Cologuard for colorectal cancer screening + Oncotype DX for breast cancer prognosis) operates substantial genomic + cancer-detection ML organizations supporting senior genomics DS at $145-215K TC. American Family Insurance HQ Madison (Fortune 500 mutual insurance, ~$14B revenue) operates substantial actuarial + claims + telematics ML — American Family is one of the country's largest auto + home telematics-data underwriters. WI's 7.65% top bracket catches senior DS at $300K+ TC, but the bracket is substantially lower than MN's 9.85%. WI does have a 30% capital gains exclusion (effective ~5.36% on ) — distinctive vs MN's full ordinary-income treatment, supporting better employer-equity tax treatment for FAANG-remote DS.
