We only have an idea so far. Can we still consult?

Yes. We organize the idea, then list the required deliverables and scope, such as a specification or MVP plan, in the quote and contract.

How is an MVP different from a finished product?

An MVP is the minimum scope needed to test a core hypothesis. Haru is a planning-to-MVP case; validation results determine any later scope.

Planning & MVP Validation

We narrow an idea to a feasible scope and design and build an MVP to test its core hypothesis.

Scope and deliverables

Scope: Service concept, screen and feature specifications, scope and schedule estimates, and an MVP carrying only the core features
Deliverables: Specifications, scope and schedule documents, and a validation MVP listed in the approved quote and contract

How we build it

We select the concept, screen and feature specifications, scope, schedule or MVP work needed, then agree on the purpose and validation criteria.

When planning, design and development are contracted together, they follow one specification. An MVP covers only what the core hypothesis needs, and validation informs any later scope.

What we take on

Concept organization and specification writing
Screen composition, user flow, and feature specs
Project scope and schedule estimation
Core-feature-focused MVP development
Decision support such as design-concept comparison
