No subcontractors.
No black box.
Full ownership.
Flutter app development, Firebase backends, and admin dashboards—built entirely by our in-house team in Seoul.
A Seoul-based product studio where the CEO still writes code, the entire team works in-house, and you see real progress from day one.
WHO WE AREWhat is Neoul?
From a small idea to a wave that reaches farther.
작은 아이디어가 더 넓은 세상으로 퍼져 나가는 힘.
Neoul (너울) is a Korean word for a broad ocean swell—formed far offshore and carried steadily across the water. To us, it represents small ideas gaining momentum and reaching farther than expected. We build digital products that create meaningful change for businesses and the people they serve.
The problem isn’t talent.
It’s structure.
Competitors
Software outsourcing projects fail when clients lose visibility—because of unclear scope, slow feedback loops, hidden subcontracting, and inconsistent progress reporting.
Neoul
Neoul solves this with founder-led delivery, milestone approvals, and direct access to the team building your product.
How we work
01. Discovery
We define your goals, users, and core scope.
02. Planning
We map the product structure and user flows.
03. Design
We design and approve every key screen in Figma.
04. Build
You receive a working build every two to three weeks.
05. Handover
You receive the source code, design files, and six months of bug-fix support.
Three promises,
written into every contract.
PROMISE 01
No subcontractors. Ever.
Every line of custom code is written by our full-time team in Seoul. We do not resell, reroute, or white-label another vendor’s work as our own.
PROMISE 02
Verifiable progress.
The planning and design phases require your written approval before development begins. During the build, you receive a working app every two to three weeks—not a mockup, but the real product.
PROMISE 03
Full ownership.
At handover, you receive the complete source code and design files. No vendor lock-in or restrictive licensing terms. Six months of bug-fix support for reproducible defects is included.
Communication
Your timezone won’t slow the project down.
We combine scheduled overlap hours with clear asynchronous updates, so you can reach us when decisions matter and track progress at any time.

Our Team
Neoul is a Seoul-based product studio building mobile apps, admin platforms, and Flutter Web dashboards for founders who value clear communication and reliable delivery.
We started as a two-person team in 2023.
Today, we are a six-person in-house team of product strategists, designers, and engineers. We intend to stay small by design—small enough for the CEO to remain involved in every project, and experienced enough to deliver complex products.
WHAT WE BUILD WITH
Flutter + Firebase
Flutter lets us ship iOS and Android from one shared codebase—one team, one release cycle, and a consistent experience across platforms. Firebase powers authentication, real-time data, push notifications, and infrastructure that can scale from day one. We use the same stack for our Flutter Web admin dashboards.
CAPABILITIES WE SHIP MOST OFTEN
Booking & scheduling
Time slots, capacity rules, and conflict prevention.
Social & community
Feeds, follows, comments, and direct messaging.
Commerce & payments
Checkout, subscriptions, saved payment methods, and refunds.
Admin dashboards
Role-based access, operational tools, and reporting.
Auth & identity
Email login, social login, KYC, and OTP verification.
External APIs
Maps, weather, video, and AI integrations.
Partners & Clients
FOUNDER-LED FROM START TO FINISH
We only take on four to six projects a year.
If you’re building a product that needs thoughtful execution and a reliable launch, let’s talk. The first 30-minute consultation is free and available in English. After the call, we’ll send you a written summary of the recommended scope —whether or not you choose to work with us.
We can communicate in both English and Korean.
