Here at Evidence Action, we’re always looking for big ideas — the game changers, the unicorns — solutions that have potential to change and save millions of lives.

And the way we do that is through our Accelerator. 

The Accelerator is our engine for new program development — it’s how we evaluate, select, optimize, and test at scale interventions that can measurably improve millions of lives. 

We’ve built a rigorous six-stage process that ensures only solutions with the greatest potential for cost-effective impact are scaled up — that’s how we maximize the impact of every dollar invested. 

Wondering how it works? Since most of the action happens behind the scenes,​​​ we put together this deep dive on the Accelerator so you can learn what the process looks like in practice, what happens if an intervention fails to advance to the next stage, how interventions develop into at-scale programs, and more.

Take a look inside the Accelerator and learn more about how we’re  delivering the most benefit for the lowest cost.​
