Former Zomato co-founder Pankaj Chaddah made a comeback as an entrepreneur in October last year with mental fitness studio Mindhouse. Since then, the company has opened a few studios in Gurugram and now has raised about Rs 15 crore from a clutch of individuals. Chaddah himself has poured around Rs 10 crore in the six months old venture while blue-chip angels such as Anand Chandrasekaran, Sahil Barua, Karan Singh and Ambarish Raghuvanshi have also participated in the financing round through debt.
