PoC Support
Netsujo Inc. supports new-business teams, technical leads, and enterprise planning offices from defining PoC success and KPIs through prototype development and validation. We design around real constraints — existing-system integration, approval workflows, staged budgets — so a PoC that starts small and fast can still carry through to production. Published pricing: JPY 500,000–2,000,000 for the concept phase, JPY 2,000,000–8,000,000 for the PoC phase.
- What
- Designing PoC success criteria, KPIs, and exit conditions, through prototype development and technical validation.
- How much
- JPY 500,000–2,000,000 for the concept phase; JPY 2,000,000–8,000,000 for the PoC phase. A fixed-price Web3 PoC Design package (JPY 800,000, excluding tax, 4 weeks) fixes the amount and delivery date before you commit.
- How far
- Four phases end to end: problem framing and hypothesis design, business decision and production design, and production development and operation.
Pricing by phase
| Phase | Price | What it covers |
|---|---|---|
| Concept phase | JPY 500,000–2,000,000 | Defining the hypothesis, KPIs, and exit criteria to validate — including whether a PoC is warranted at all. |
| PoC phase | JPY 2,000,000–8,000,000 | Minimal-scope prototype development, user testing, and technical feasibility validation, with weekly progress sharing. |
| Production phase | JPY 8,000,000+ | Production development and operation, with staged scale-up support. |
Actual scope and price vary by target area and validation range. We quote individually once the minimal scope is agreed.
Why a PoC ends up going nowhere
- Success criteria are vague — judged only by "did it work," without validating business viability, user value, or operability. A PoC’s purpose is to produce evidence for the next decision.
- No production hand-off design — security, scalability, and regulatory gaps between the PoC and production environments are never addressed, so the project stalls at PoC.
- Stakeholders aren’t brought in — technical validation proceeds without buy-in from leadership, business units, or legal, leaving nobody to translate the result into a business decision.
Roadmap from PoC to production
| Phase | Duration | What happens |
|---|---|---|
| 1. Problem framing & hypothesis design | 2–4 weeks | Business-problem interviews, judging whether Web3 applies, setting the hypothesis and KPIs to validate. |
| 2. PoC execution & validation | 4–8 weeks | Minimal-scope prototype development, user testing, technical feasibility validation, weekly check-ins. |
| 3. Business decision & production design | 2–4 weeks | Business-decision report on the PoC result, production requirements, security/regulatory review, executive briefing materials. |
| 4. Production development & operation | 3–6 months | Production development and deployment, monitoring setup, staged scale-up. |
Enterprise-specific considerations
- Fixing existing-system integration scope during the PoC — clarifying which systems connect, and whether integration can be validated in a test environment, up front, to reduce rework at production hand-off.
- Working with staged budgets and approval flows — splitting scope across concept, PoC, and production so each phase can clear its own approval, rather than needing full-cost sign-off up front.
- Designing exit criteria and steering — setting exit conditions before starting, sharing progress with the team weekly, and giving leadership monthly steering checkpoints so a stalled PoC can actually be stopped.
Frequently asked questions
- What counts as a successful PoC?
- Not that the prototype ran, but that it produced the evidence needed to decide whether to move to production, continue, or stop — covering technical feasibility, user value, and business viability.
- How long should a PoC take?
- There’s no universal answer, but generally a few weeks to about three months — enough to gather the evidence needed for the go/no-go decision, not to build a polished product.
- What does a PoC cost?
- Our published ranges are JPY 500,000–2,000,000 for concept, JPY 2,000,000–8,000,000 for PoC/prototype, and JPY 5,000,000–15,000,000 for MVP development. A fixed-price Web3 PoC Design package (JPY 800,000, excluding tax, 4 weeks) is also available when you want the price and date fixed up front.
- What should a Web3 PoC watch for specifically?
- Beyond technical validation, check legal risk, private-key management, gas/chain fees, and wallet-connection UX during the PoC itself. Because a deployed smart contract is hard to change, security review should start at the PoC stage — testnets often hide gas, liquidity, and regulatory issues that only appear on a production chain.
Areas we can take on
This describes areas we can discuss, not a list of delivered projects: new-business development across industries, local-government DX and pilot programs, tourism and regional engagement, community and membership services, and proof/distribution of content and IP; technically, blockchain (NFT/SBT/DID/VC/token design), smart-contract pre-order review, applied generative AI/LLM validation, web and mobile app prototyping, and integration testing with existing systems. Fit is judged case by case in the first consultation against your hypothesis, systems, budget, and schedule.
We’ll help structure the hypothesis and success criteria together, including exit conditions for the business decision.
