Documented cause
Cityblock Health was founded in 2017 by Toyin Ajayi with backing from Sidewalk Labs (Alphabet). It built integrated care teams to serve Medicaid and dually eligible populations — delivering real clinical outcomes but at unit economics that required years to reach profitability. The company raised over $900 million and reached a $5.7 billion valuation in 2021. In 2022 and 2023, Cityblock reported over $100 million in operating losses and laid off approximately 20% of its workforce, pulling back from several markets as VC interest in the sector cooled.
Lesson
“Medicaid reimbursement rates were never designed to sustain VC-backed growth models. Value-based care savings materialize over 5-7 years — incompatible with the 3-4 year VC cycle.”
