Over the past decade, Sunil Sandhu has founded and built a range of products and companies for developers and founders. Here's what he's working on and what he's built.
Developer education platform read by millions each month
A tech-focused media company and developer education platform, home to publications such as JavaScript in Plain English, Python in Plain English, and Stackademic. It has grown into one of the largest developer education platforms in the world, reaching millions of readers across 200+ countries.
AEO & LLM-visibility monitoring for brands
Sunil's current focus: a platform that shows brands how they appear inside AI answers. Obsurfable tracks how large language models like ChatGPT describe you, which questions matter in your space, and which competitors show up instead — so you can optimise for answers, not just rankings.
An algorithm-free blogging platform built for the AI era
A blogging platform built for a world where both humans and AI agents read content. Differ is deliberately algorithm-free, a bet that meaningful writing can win in a vertical crowded by Medium and Substack. Two years in, it serves hundreds of thousands of monthly views.
Developer marketing agency for devtool & SaaS startups
A developer-marketing agency helping devtool and SaaS teams create technical content and marketing strategies that drive real developer adoption — backed by an owned distribution network of tech publications.
A free coding bootcamp built during the pandemic
A free coding bootcamp Sunil built during COVID to teach people how to code all over the world. He built the platform, wrote the curriculum, taught the students, and marked the homework himself.
Real, unpolished founder stories and community
A community built on the belief that momentum beats perfection. Messy Founder is a home for real, unpolished founder stories — builders helping builders, without the highlight-reel pressure.
