Cityblock was developed by the urban innovation technology group within Alphabet.

Cityblock is truly differentiating itself from other HealthTech companies, with a focus on social justice initiatives that directly impact healthcare in marginalized communities. Cityblock actively focuses on this high-risk market and partners with local community-based organizations to help its members get access to primary care, behavioral healthcare and social services. In addition to medical care, Cityblock also attends to social needs, such as childcare, housing and transportation.

Cityblock favors a value-based healthcare model over the fee-for-service one, collecting fixed payments per member and providing personalized and tech-enabled care to patients.

By scaling its operations and technology, Cityblock is on track for executing its vision of upending a broken healthcare system and aims to serve 10 million members by 2030. Cityblock projects growth and expansion into more states in 2022 including Ohio and many others.

Cityblock reports significant reduction in patient hospital admission rates and overall improvement in quality outcomes, with data from its first member cohort reporting a 15% reduction in ER visits and a 20% reduction in hospital stays.

Cityblock sees 70% user engagement activity in its platform versus the health plan industry average of 5-7% and receives 85+ average NPS (Net Promotion Score)—which measures customer loyalty—versus provider industry average of 15.

Cityblock is building the largest dataset of its kind for social-medical factors and applies machine learning and data science techniques to unlock nuanced population segments, develop prioritization algorithms, and provide behavioral decision support for medical staff. Cityblock’s Alphabet-backed technology program, Commons, keeps patient data in one location so that providers can collaborate on a care plan.

According to Forbes, Cityblock doubled its membership and tripled its revenue growth in 2020. The Company’s 2020 revenue run rate was ~$400 million.

Cityblock reports monthly revenue between $1,100-$2,000 per member via patients with state and federally-funded health plans like Medicaid and Medicare.
