Terraformation CEO Yishan Wong On Reforesting 3 Billion Acres

Most Silicon Valley CEOs who cash out their stock options start another tech company. Yishan Wong planted trees instead. After helping build PayPal, Facebook, and serving as Reddit's CEO, Wong concluded that humanity's biggest challenge wouldn't be solved with algorithms or network effects—it would be solved by restoring the planet's forests at an unprecedented scale. Mitch Ratcliffe sits down with Wong to discuss Terraformation, the company he founded in 2020 with an audacious mission: restore 3 billion acres of native forest worldwide—an area larger than the entire United States.

Planting a trillion trees isn't just about seeds in the ground. It's about solving bottlenecks like funding gaps that leave 95% of qualified forestry teams without resources, seed shortages, lack of infrastructure and technology, gaps in tracking and verification. Terraformation built a support system that includes modular seed banks, solar-powered nurseries, open source forest management software, which is called Terraware and a seed to carbon forest accelerator that's modeled on tech startup accelerators. Since founding Terraformation, Wong has enabled the planting of over 4.7 million trees across 394 species, established 19 seed banks and 21 nurseries and created more than 798 jobs.

"We made Terraware not because this is the most genius piece of technology that will change the world," Yishan explains. "We said, hey, let's just help forestry teams achieve certain basic necessary activities." Unlike commercial timber plantations that prioritize fast-growing monocultures, Terraformation focuses on biodiverse native forests. Native tree species can support an order of magnitude more life than non-native species because they've co-evolved over millions of years. "Trees are the anchor species for a forest ecosystem," he added. "What you're doing is you're growing trees as the anchor species so that all of the other life in that forest ecosystem comes back."

Terraformation recently won the Keeling Curve Prize and the G20's RestorLife Award. The company also received recognition at the Global Sustainability Awards, winning SME Company of the Year. Yishan explains why a former Reddit CEO believes in low tech solutions that are the right approach to climate change, how Silicon Valley's lessons about scaling systems could apply to reforestation and what it takes to build an organization designed to be replicated rather than defended.
