In our last episode, we covered a recent study on climate venture studios conducted by Jamil Wyne and Hazelwood Network and discussed the role studios can play in accelerating climate innovation. 

Today, we’re seeing what that looks like in practice in a region critical to our climate future.

Across Southeast Asia, growing incomes and rapid urbanization are driving demand for energy, housing, and food. Meeting those needs creates an enormous business opportunity—and the choices made today will shape emissions for decades.

Our guests are Steve Melhuish and Marie Cheong, founding partners of 100x100, which builds climate companies across Southeast Asia and India. Their first fund raised $60 million and launched 26 businesses, with companies generating revenue in just five and a half months, on average.

We explore how they recruit experienced entrepreneurs, identify overlooked opportunities, and build businesses that can deliver both financial returns and meaningful emissions reductions.
