About Siddharth Sambharia

I am a generalist working across product, marketing, and engineering. I currently work at Portkey, now part of Palo Alto Networks, where I spend time helping build and explain software for developers working with AI.

This site is my public notebook and personal home on the web. I use it to publish essays, technical explanations, notes from books, and small experiments. The recurring subjects are artificial intelligence, large language models, agents, software products, internet history, and the habits that make ambitious work possible. Some pieces are polished essays; others are deliberately unfinished notes that show an idea while it is still changing.

I also build small tools. Prism is an AI Chrome extension that lets you ship features to any website. How the Internet Happened is a visual timeline of internet artifacts and ideas inspired by Brian McCullough’s book. I am interested in projects where writing, product thinking, and implementation reinforce one another.

For collaboration, corrections, or a thoughtful hello, send me an email or get in touch. You can also find me on X, GitHub, and LinkedIn.
