After the model was finalised, Vamsi reached out to Luthra, asking him to teach physics on a part-time basis and later persuaded him to join the organisation in a senior management role in September 2019. On Luthra’s part, the doubt about coming back never existed. When asked about what he feels the founders were able to learn and do differently post 2017, he says, “Fundamentally, the difference is in the approach in solving problems. Earlier, if there was something we thought would work out, we went all in. Now, it’s more of an experiment on a smaller scale. If it works, scale it, if it doesn’t, tweak it. We are careful to not fall into wishlist traps or have a tendency to burn cash.”
