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.
Publication for founders and indie hackers
A publication for entrepreneurs, founders, indie hackers, and ambitious builders — sharing ideas, stories, lessons, and resources on startups, growth, and the realities of building something from nothing.
Insights on the technologies shaping the future
A publication covering AI, crypto, Web3, software, and emerging technologies — practical insights and analysis for developers, founders, and curious builders, without the hype.
Coverage of answer engine optimisation and AI search
A publication for marketers and growth teams tracking how the internet is changing again — answer engines, AI visibility, and the new verification layers reshaping discovery.
Culture, memes, lifestyle, and group-chat energy
A publication covering culture, memes, lifestyle, and the stuff that lives in the group chat — trending stories for people following what’s happening now.
Science, innovation, products, and engineering
Journal (of Science, Innovation, Products & Engineering) explores the ideas, technologies, and products moving the world forward — for scientists, engineers, and curious builders.
Reviews and comparisons for tech buyers
There are more products, platforms, and services than ever — Salt Index helps tech buyers and researchers choose between them with clear reviews, comparisons, and briefings.
Tech and software for teams building the future
A technology publication for software teams and tech leaders — covering the products, platforms, and shifts that matter as everything becomes technology.
Transactional email API for developers
The minimum email infra for developers: send transactional email — password resets, onboarding, notifications, and receipts — observe delivery, and skip the template suite. Create an API key, verify your domain, and send.
Publishing & digital PR marketplace for brands
A curated publishing network (evolved from Circuit) that gives companies access to technology, business, and niche websites — so you can create content, secure placements, and distribute your brand without traditional publisher outreach.
