What We Do

The Transformative Development Initiative (TDI) is MassDevelopment's flagship program that partners with communities to strengthen downtowns and commercial districts in Gateway Cities.

Through a three-year partnership and accelerator framework, we collaborate with cross-sector local leaders and organizations to drive meaningful district transformation. We commit intensive, multi-year resources to a neighborhood—simultaneously advancing real estate development, supporting small businesses, activating public spaces, and strengthening local economies. Our approach is direct, hands-on, and rooted in deep collaboration, helping communities build on the assets that already make them strong. By focusing on neighborhood revitalization, we aim to create lasting economic opportunities and clear pathways for wealth building for residents and local stakeholders alike.

TDI’s Theory of Change is to bring a practical toolkit of targeted financial and human capital to support this work, from small grants and technical assistance to real estate support and district level strategies. These resources are shaped by local priorities and designed to help communities move ideas into action, test what works and build momentum over time.

TDI Uses An Accelerator Model

TDI Uses An Accelerator Model

We commit intensive resources to a district for a defined time—simultaneously working on real estate development, small business stability and growth, arts, and cultural amenities, placemaking, and targeted technical assistance and strategic planning. This work is laid on a platform of community engagement and partnership development; we require that cities assemble a cross-sector partnership to apply in the first place, and over the course of the program we work to make the partnership more representative of the neighborhood and use it as a platform to grow sustaining, working relationships.

Tools That Drive District Transformation

TDI deploys a set of tools and investments into each district, collaborating with local partners to support progress over time.
