The Insurance Company That Started With a Bet on Farmers
A hunch about farmers in 1927 grew into a top-ten American insurer. Here is how American Family Insurance built a mutual empire on the promise to inspire, protect, and restore dreams.
Olli Health
Olli Health is a Madison, Wisconsin healthtech company that runs an AI-powered managed service for home health coding and OASIS quality review. It pairs proprietary clinical AI with certified human coders to turn raw patient charts into accurate ICD-10 diagnosis codes and reviewed documentation - reportedly at 98%+ accuracy, roughly 4x faster turnaround, and about half the cost of traditional coding vendors. Founded in 2023 by Eric Steege, Joe Freudenthal, and Jeremy Gordon, Olli serves home health agencies that collectively care for hundreds of thousands of patients, and raised a $10M Series A in late 2025.
WellStack
WellStack is a Madison, Wisconsin healthcare data platform that unifies fragmented clinical, financial, and operational data into a single governed source of truth. Built on a cloud-native Unified Data Model and a Snowflake foundation, it gives providers, payers, and data collaboratives out-of-the-box Patient/Member 360 views, modular Decision Hubs, and AI/ML-ready analytics - so healthcare organizations can predict, prevent, and personalize care without the years-long data-engineering slog.
