Build it from scratch
You have the idea. We turn it into a product your customers can actually use.
For founders with an idea, a broken app, or a product outgrowing itself
You bring the idea.
We build the product.
Kaunji is an AI-first tech lab. We build products from scratch, rescue vibe-coded apps that broke, and scale the ones that work.

Three ways teams bring us in.
AI writes the first 80% in a weekend. The last 20% is where products die, because of the edge cases it skipped, and the load it was never tested for.
Every month you build on that foundation, it costs more to fix. This is exactly where we come in to fix it for you.
Rescue your vibe-coded app
It demoed beautifully and fell over in the real world. We find what is genuinely broken and make it safe to run.
Scale it and add AI
More users, more load, and AI put where it earns its keep.

Real founders, real launches
Real experiences from the teams we integrate with. We are the engineering muscle executing the applications our clients define.
“I had a vision for a private email product but no technical background. They turned my references into product flows and built the whole platform—groups, questions, automated collection, compiled newsletters, and subscriptions. Ten months later we had a launch-ready SaaS, not a prototype. That founder collaboration is rare.”
“We had a high-fidelity, image-heavy Figma and a sixty-day deadline. They built the frontend from scratch, integrated our backend, and shipped a pixel-accurate site without losing its visual character. Performance scores landed above 90. For a design-led product, that fidelity under pressure is exactly what we needed.”
“High application volume was drowning our team, and keyword filters could not capture the nuance we needed. They built an AI pipeline that parses resumes, scores candidates against our criteria, evaluates GitHub submissions, and notifies us in Slack. It processed more than 30,000 candidates with about 97% agreement to our reviewers.”
FAQs.
Yes. Most of our rescue work is code someone else, or something else, wrote. We can help you understand the code and make it work for you.
