BUSINESS
We hold both in-house SaaS development capabilities and startup consulting experience,
along with a B2B distribution network.
Diagnosis, design, execution, and market access
are established as a single 'one-stop value chain'.
Business
AI Native Development
A team that has built products firsthand
creates services for our clients.
MMJ GROUP develops and operates the UTON Margin Calculator (유통계산기 AI) and
Changbo Managers (창보매니저스) entirely in-house.
From planning and development to deployment, incident response, and customer support,
a single team handles the entire process.
We apply the same standards to client projects,
adjusting at the kickoff stage any initial requirements whose
actual usage rate is expected to be low.
As a result, the launch date is brought forward
and initial operating costs are reduced.
Development Plans
Development Services
You can start from whichever stage you need right now.
There is no need to build a fully finished service from the outset.
We recommend developing only as much as validation requires, checking the response,
and then moving on to the next stage.
01
Market Validation Development
KRW 1M – 3MAbout 2 weeks
This stage checks the market response
before development begins.
We build a landing page and a pre-registration flow,
then drive real traffic to verify demand.
Deliverables
- Landing page
- Pre-registration or payment test
- Traffic data report
Recommended for
- When you have an idea but demand is unconfirmed
- When you need a basis to decide whether to begin development
02
MVP Development
KRW 3M – 5MAbout 4 weeks
We select only the service's core features and implement them
in a form users can operate directly.
Supplementary features are not developed at this stage.
Deliverables
- 1–2 core features
- Basic member and administrator features
- Deployment to a live server
Recommended for
- When you need to secure early users
- When you need a working screen for grant programs or investor meetings
03
Full Service Development
KRW 15M – 30MAbout 8 weeks
Operating an MVP in practice reveals which features are used
and which are not.
At this stage, we use that data as the basis
to distinguish features to expand from features to remove.
Deliverables
- Member and permission system
- Payment integration
- Administrator system
- Data analytics foundation
Recommended for
- When you are beginning paid conversion
- When early clients are secured and operational stability is required
04
Service Enhancement Development
KRW 30M – Custom12 weeks or more
As users and data grow, we improve the system architecture
and, as essential steps, carry out
external integrations and
operational automation.
Deliverables
- System architecture redesign
- External system integration
- Operational automation
- Maintenance and incident response framework
Recommended for
- When traffic has increased
- When technical validation and enhancement are needed ahead of follow-on investment
Strategy
Development and Commercialization Strategy
Development is not the goal but the means. We design projects systematically not around the point where the product is finished,
but around the point where revenue and funding are secured.
STRATEGY 01
Validate on our own products first
The technology stack and development processes we apply to clients are first used on our own SaaS. We absorb the trial-and-error cost of new configurations and apply to clients only the methods proven in operation.
STRATEGY 02
Decide the development scope by metrics
Deciding what to cut is the first step of development; the more we cut, the sooner the launch date and the lower the initial operating costs.
STRATEGY 03
Define the business model first
We finalize the revenue structure before screen design. In the planning stage, we review the business model together with the pricing structure — who we sell what to, and at what price.
STRATEGY 04
Design stages around the funding schedule
The development schedule follows the funding schedule, not the technical one. We first confirm grant agreement periods, investor meeting timing, and documentation requirements, then divide the development scope.
STRATEGY 05
Connect through to commercialization
The real start comes after the product is out. Writing the business plan, responding to grant programs, and securing early market access are supported continuously within the same organization.
STRATEGY 06
Hand over with documentation
We document data flow diagrams, error-checking procedures, and handover items for personnel changes. Our goal is a state you can operate with in-house staff without remaining dependent on the development firm.
