We Design, We Build.

Choie is a design-led product studio for founders and companies. We design and build web and mobile products, and we do it fast, with AI and our own kit. What makes the work good is senior design judgment: what to build, what to leave out, and how it should feel. The same people make the design calls and write the code that ships.

Founders, early teams, and teams inside larger companies who need design and engineering in the same hands for a defined project. That covers taking a product from an idea to a first version, building a new product or internal tool, or making one that is already live easier to use.

Yes. Teams often start with a one-week working prototype of an idea they need to show leadership before it gets a budget, then we design and build it inside their team. Projects include new products, internal tools, and prototypes that need to become production software. Company projects get a written scope and start from $19,000. We sign NDAs and GDPR data processing agreements, invoice against purchase orders with agreed payment terms, and work inside your systems and alongside your team.

Three things. Decide: product strategy, user flows, and interface design. What to build first, what to cut, and how it should feel. Build: production apps for the web, iOS, and Android, made fast with AI and our own kit. Launch: a site that explains the product, then measurement of how people use it.

A one-week prototype is a fixed $4,900. A full build starts at $19,000. Ongoing monthly work starts at $9,900 per month. All prices are in US dollars, and no tax is added on top. Every project gets a written scope with a fixed total before any work starts.

A prototype takes one week. A full build takes four to six weeks. Monthly engagements run open-ended and can be ended any month. You get the written scope and a fixed date within two days of the intro call.

You do. Once the fees for a deliverable are paid in full, the designs and the source code written for you are yours to use, modify, and distribute without restriction. Third-party libraries, fonts, and software stay under their own licenses.

We fix defects in our own work at no charge for 30 days after launch. Past that, a month-to-month engagement covers ongoing changes and fixes.

Yes, and it's a big part of why we're fast. Our own kit of interface components, motion and micro-interactions is the other part. Neither one decides what to build or how it should feel. That's senior design judgment, and it's what you're hiring. Senior people also decide the architecture, review every line, and own testing. Once it's paid for, the code is yours.

Yes. Real applications for the web, iOS, and Android, not wrappers around a website.

One 30-minute intro call about your goals, your users, and what is in the way. No preparation needed. A written scope and a fixed price follow within two days.

Start with the one-week prototype. You get one critical workflow as a coded product experience with real behavior, not a Figma mockup, plus a concise recommendation on what to build next. If you begin a build within 60 days, the fee is credited in full.
