Anyone can create an impact on their own, but those who want to drive system-level change work with a team.

We match ambitious leaders, strong concepts, and capital with the executional power required to launch and scale transformational development ventures.

More than ever before, the world needs meaningful and transformational action.

Our Unconventional Approach

GDI is an incubator for transformational development ventures, working to build and scale the next generation of social impact solutions.

Whether these concepts originate from sector experts, or are developed and tested ourselves, we create new approaches to address persistent global issues.

Break Silos

We listen closely, interrogate the process, and bridge sectors to arrive at the best solutions to specific problems.

Hold Ourselves Accountable

We work closely with our partners every step of the way and measure our success by the real-world impact we create, not simply the advice we deliver.

Make the Connections

We catalyze potential partnerships and connect opportunities for funders, individuals, and organizations to work together towards common goals.

Think Long Term

We engage and empower organizations and initiatives to stand on their own as influencers in their fields.

We provide our partners intensive and comprehensive collaboration throughout the life-cycle of a new venture.

Our Growth Engineering Process

Over 12-36 months, we deploy our functional teams to help early-stage initiatives design their business strategy and model, develop their brand identity, hire and retain talent, and construct their financial and operational infrastructure.





Conduct a thorough and thoughtful review to understand the root problems and a hypothesized solution. Develop key business plan questions and refine an early concept note.

Collaborate with partners and funders to align on theory of change, validate the approach, build a governance system, and shape a powerful brand.

Develop leadership teams, pilot interventions with emerging results, build core operating infrastructure, and establish a strategic plan.

Launch entrepreneurs and incubated initiatives into the next phase of growth. Set future milestones and transfer knowledge to ensure the initiative’s long-term success.

For social impact pioneers, GDI serves as both a guide and implementer, looking to elevate our ventures and the broader causes they represent.

Our Work and Featured Initiatives

From a venture’s discovery to its operational building blocks, we leverage our outsider experience and insider commitment to turn big ideas into action. We are committed to working with our partners for the long-haul, crossing sector boundaries to forge critical relationships between traditional and non-traditional development actors.

Browse our incubated initiatives to see how we design and build transformational development ventures, and read our thought leadership to learn more about the ideas that power our work.

GDI is your trusted advisor when you need guidance, your “start-up team” when you need to get stuff done, and a mentor when you need a push in the right direction.
