About
We build the system, then we hand you the keys.
Renga Technologies is a founder-led build studio run by Karthik Rajan. We've shipped production Laravel systems since 2022: ordering platforms, clinic software, lending tools, procurement and admissions systems. Now we put that same discipline into AI agents, voice agents and custom apps for SMBs and startups.
Why fixed price, and why Laravel
Most of our early clients were small businesses in Tamil Nadu: fireworks retailers, a clinic software company, a college, an agri-trader. None of them could afford a project that ran over or code nobody else could maintain. So we learned to scope tightly, price up front and build in plain, testable Laravel.
When AI got good enough to do real work, our clients started getting pitched Python notebooks and 'AI platforms' they couldn't run. We build AI the same way we build everything else: inside an app with an admin panel, logs and tests, owned by the client.
I scope every project and review every release. If we can't help, I'll tell you on the first call.
