Our promise

Hiring a dev shop is scary. We make it safe.

You’ve probably been burned before — by overruns, ghosting, or code you couldn’t touch. Here’s what we guarantee in writing.

Fixed-price quotes

You approve a clear, fixed price before any work starts. If scope doesn’t change, the price doesn’t either.

You own everything

On final payment the code, designs, and accounts are 100% yours. No lock-in, ever — take it anywhere.

On-time or we make it right

We commit to a launch date in writing. If we slip on our end, your next month of support is on us.

A human who answers

Real people, US-based, who pick up the phone. Most support requests are handled the same day.

인연
BIZUSER
The meaning behind the name

인연 — the connection that brings the right people together.

In Korean, inyeon (인연) is the idea that meaningful relationships aren’t random — they’re the connections meant to happen. It’s the perfect word for what good software does: it connects a business to its customers, its team to its tools, and an idea to the thing it was meant to become.

That’s how we work too. We don’t hand you off to junior staff or vanish at launch. We partner with you — even for the long run — because the best work comes from a real connection between the people building and the people it’s built for.

Connecting ideas. Building solutions.
The team

Meet the people who’ll build it.

Founded in 2026, we’re a New York City software development studio — four co-founders, one product team. Full-stack engineering, marketing, UX, and operations under one roof, building one thing for you. No account managers, no handoffs to junior staff: the people you meet are the people who build and ship your project.
