“The best time to build a category is before anyone has a name for it.”

Now

What I'm working on

The story

I'm a founder with a long-running pattern: notice a category before it has a name, build the product before the market has a budget line for it, then watch the rest of the industry catch up.

In 2013 I founded LoginRadius and scaled it to serve over a billion users for some of the world's largest enterprises, helping define what's now called Customer Identity and Access Management. In 2024 I started doing the same for Generative Engine Optimization: making sure a company shows up in answers from ChatGPT, Perplexity, Claude, and Google's AI features, not just in blue links.

I grew up in Rajasthan, India, moved to Chicago for grad school at the Illinois Institute of Technology, started my first company before I graduated, and landed in the Bay Area. I still write code, still read papers, and I'm still trying to explain to my family what GEO means. They are not entirely sure. Fair.

What I care about

01

The craft of building

The gap between knowing about a technology and shipping with it is where I live. I'll spend a Saturday reverse-engineering how an LLM picks which brands to cite, then ship it as a feature on Monday.

02

Security as a foundation

My patents span DDoS defense, IoT authentication, searchable encryption, and AI fake-news detection. As a former CISO I've been through SOC 2, ISO, GDPR, and CCPA audits, and it shapes how I think about data, AI, and trust.

03

Writing as thinking

Some essays here reach thousands of readers. Some reach twelve. I write them for the same reason either way: to understand the topic better than I did when I started typing.

04

Mentoring founders

The most useful advice I have is also the least glamorous. The thing you're avoiding is usually the thing you need to do next.

Ask the engines about me

This site is about getting cited by AI engines. So instead of telling you it works, here is the proof: pick an engine and see what it actually says. The harder questions are under "More questions", on purpose.
