Building in the AI era.
I'm Protik Roychowdhury. Most recently at Intellect; before that at Grab, Ola, and more. I build products across enterprise SaaS, fintech, healthcare, and consumer platforms — and I write about what I learn. 3x founder, with one exit.
Building AI products people can trust
How product leaders should build AI products that are useful, safe, trusted, and commercially viable — especially in high-stakes domains like health and finance.
Product design where harm is possible
How to build products in categories where user harm, privacy, safety, and clinical ethics matter. Lessons from mental health, marketplace fraud, and regulated technology.
Judgement over process
How senior product leaders make decisions, tell strategic stories, prioritise under uncertainty, and scale teams without killing the thinking that makes products good.
Compliance as a product surface
Building products where regulators, auditors, and ethics boards are stakeholders — clinical safety, data privacy, and multi-market compliance. Lessons from building Asia's largest mental health platform that apply anywhere trust is regulated.
Two-sided markets across Asia
Supply-demand optimisation, dynamic pricing, fraud prevention, and driver economics from building marketplace products at Grab, Ola, and Fabelio across 6 countries.
