About

Product leadership for scalable human + AI wellbeing.

For Rustum, Crink began at home. After watching his wife and co-founder, Mariyam, leave her engineering career to balance parenthood, he realized millions of professionals faced the same struggle.

While Mariyam studied psychology to find answers, Rustum focused on the product question: how do you scale deeply personal growth to thousands without losing the human touch?

Today, Rustum leads product at Crink, turning that personal mission into a platform that supports professionals and families across India, the GCC, the UK, and the US.
