Building tech
for the overlooked.

I build things, back founders, and write honestly about the parts of entrepreneurship nobody talks about. Based in Chennai. Started with nothing in rural Tamil Nadu — still figuring it out, still shipping.

Arun Rajiah — open-source developer and entrepreneur

The long version

Grew up in a small town in Tamil Nadu. Found my way into startups through sheer stubbornness — failed projects, expensive mistakes, and a few wins that mattered. Over 18+ years, I've been a founder, operator, investor, and the person founders call at 2am when everything is on fire.

Today I run Lvl1 Accelerator, back early-stage companies, and build open-source AI tools for communities that mainstream tech tends to overlook — conservationists, non-profits, small publishers, independent teams. Not because it's a good story, but because someone has to.

I also write. My newsletter and books aren't strategy decks — they're honest conversations about the parts of building nobody talks about. The loneliness. The self-doubt. The moment you realise your product solves a problem nobody actually has. I've been there. Most good founders have.

If you're building something real — or trying to figure out whether to start — I'm probably interested. Let's talk.

💻

Open Source

AI tools and web apps for the teams mainstream tech ignores. Free, self-hostable, no enterprise pricing BS.

🚀

Startup Mentor

Managing Partner at Lvl1 Accelerator. I help early-stage founders with the non-obvious stuff — hiring, GTM, and knowing when to pivot.

📖

Author

Three books and a weekly newsletter. No highlight reels — just honest writing about what building actually looks like.

💡

Investor

Betting early on founders solving real problems — especially in markets where the big funds aren't paying attention yet.
