Tim Brown is the co-founder, co-CEO, and creative vision behind Allbirds, the sustainability-focused shoe company he co-founded in 2015.

In this conversation with Stanford adjunct lecturer Ravi Belani, Brown discusses his predictions for a future economy shaped by carbon accounting and reflects on how aspiring entrepreneurs can learn from his experiences building a sustainable brand.
