Who We Are: The Team Behind 50+ Successful Launches
We Actually Write the Code
No outsourcing to offshore teams. No juniors learning on your project. Every line of code is written by senior developers with 8+ years of experience. When you talk to us, you're talking to the people building your product.
Founded in 2024 by Kenny Tran, a developer who spent 8+ years building SaaS products that scaled to thousands of users. Frustrated with agencies that talked a good game but couldn't deliver, he built Ketryon differently: senior developers only, transparent pricing, fixed timelines, and you own all the code.
We've Been In Your Shoes
Before Ketryon, we built and sold our own SaaS products. We know the stress of deadlines, the fear of technical debt, and the frustration of scope creep. That's why we deliver on time, write clean code, and never surprise you with extra costs.
Today, we're a tight-knit team of 5+ senior developers specializing in React, Next.js, and TypeScript. We've launched 50+ apps across healthcare, fintech, and SaaS—with zero failed projects. Our clients don't just get code; they get a partner who's been in their shoes.
Our Commitments (With Receipts)
Senior Developers Only
No juniors, no interns, no contractors we barely know. Our core team has 8+ years of experience each. Check our GitHub—we contribute to open source. Check our LinkedIn—we've worked at real companies. Check our references—they'll verify everything.
Weekly Demos, Not Monthly Excuses
Every Friday, you see working software. No 'we're still working on it' updates. Actual features you can click, test, and give feedback on. In 50+ projects, we've never missed a Friday demo.
Your Success = Our Reputation
We don't do 'build it and disappear.' We offer 90 days of free bug fixes. We respond to support requests in <48 hours. We write documentation like someone else will maintain it—because someone probably will.
Transparent Everything
Pricing: Quoted upfront, no hidden fees. Progress: GitHub access, real-time updates. Problems: We tell you immediately, not 2 weeks later. References: Talk to our clients, see our work, verify our claims.
Modern Stack, Future-Proof Code
React, Next.js, TypeScript, Tailwind. Not WordPress, not PHP, not jQuery. We build with technologies that will still be relevant in 5 years. Your next hire will thank you.
Fast, But Not Sloppy
8-12 week delivery doesn't mean cutting corners. 100% test coverage. Accessibility built in. Core Web Vitals optimized. Security best practices. Fast launch, long-term quality.
Our Numbers Tell the Real Story
Actions speak louder than words. Here's what we've actually done, with real clients you can talk to.
From MVP to enterprise. Healthcare to fintech. Mobile to web. Every project delivered on time or money back (we've never had to refund). Email us at 3 PM, hear back before lunch the next day. Real humans, real responses, really fast.
