Through the Yes/Cities platform, Deloitte works with a global and local network of collaborators to unlock urban innovation and opportunity. By bringing together leading companies, governments, investors, civil society, and innovators, the initiative creates pathways to turn ideas into scalable solutions that accelerate urban revitalisation, improve quality of life, and reimagine how local economies and communities grow and thrive.
As cities become both the epicenter of sustainability challenges and the source of many solutions, innovation must be locally driven. In 2023, Deloitte collaborated with the World Economic Forum, Salesforce, Citi, the San Francisco Chamber of Commerce, and more than 20 organizations to launch the Yes San Francisco (Yes/SF) Urban Sustainability Challenge.
The Challenge invited entrepreneurs to develop scalable, sustainable solutions to revitalize downtown San Francisco. With support from the wider innovation ecosystem—providing access to relationships, capital, and infrastructure—innovators were able to accelerate and scale their solutions locally. As of June 2026, Yes/SF has supported more than 55 innovators, mobilised over 60 organisations, and contributed more than $100 million in economic activity, positioning the city as a leading example of sustainable urban innovation.
The model has since evolved into broader Yes/Cities. In January 2025, the World Economic Forum announced its ambition to activate the model in 50 cities over the next five years, helping create pathways for cities worldwide to build more resilient economies and more sustainable livelihoods.
