A Dev Studio That
Thinks About Your
Business, Not Billables

We're a small, focused team of developers and designers. We don't upsell retainers or pad timelines. We build what you need, ship it fast, and make sure it works.

Koon10 — Our work
01

Developers, Not Account Managers

You work directly with the people building your product. No middlemen, no briefing chains — just direct conversations with engineers and designers who care.

02

We Think Like Founders

We've built products ourselves. We understand scope creep, tight budgets, and launch pressure — so we help you prioritize what ships vs. what can wait.

03

Clean Code, Built to Last

No WordPress bloat or template hacks. We write maintainable, documented code that your in-house team can take over anytime without a rewrite.

04

Fast Iterations, Real Feedback

We ship in short sprints and show you working software early and often. You see progress every week, not just a reveal at the end of the project.

Have an idea? Let's talk.

Free scoping call, no commitment.

Every milestone is documented.
You always know the next move.

We map each phase to deliverables, owners, and check-ins. No mystery emails, no vague promises — just a live plan you can trust.

Status hub

Shared Notion workspace with gantt-style timeline, owners, and decision logs updated daily.

Communication rhythm

Weekly live touchpoints, async Loom recaps, and Slack updates whenever something ships.

Escalation ready

Dedicated channel monitored by product + engineering leads so blockers never wait a day.

Average response time

Questions get a thoughtful response within 24 hours (often sooner) including weekends during launch.

As a first-time online seller, I was nervous. The YES team guided me through everything and trained me to manage my shop independently. Customers constantly compliment how beautiful it looks!
