Hello there, I'm Rahul!
Born and raised in Patna, I graduated from IIT Kharagpur with an Integrated Masters degree in Mathematics and Computing. I've founded 3 companies and invested in 10 startups over an entrepreneurial career spanning 12 years. Currently figuring out my next adventure.
I'm curious about emerging technologies, art of building businesses, history, politics and the civilisation of Bharat.

If you're building a startup, I can help
There is tremendous value in 'right help at the right time' for startups across stages. During my journey of building multiple companies, I've been extremely fortunate to get help from some of the most accomplished founders and mentors. I strive to give it back to the Indian startup community, especially to the younger founders.
