Distributed ledger that finally solved a trust problem we had spent three years arguing about

Yuki Hashimoto / Head of Product Development - East Asia Commerce KK
Verified
Jan 28, 2026

Project summary: Our engineering capacity was committed to maintaining existing systems and could not absorb a net-new build of this complexity. An external partner with the right skills was the only viable option.

Six months after go-live our platform is processing three times the transaction volume we specified in the original brief. The architecture choices made during discovery accommodated that growth without remediation work. That is the difference between a team that designs for what you tell them and a team that designs for what you are likely to need. We are in conversation about a Phase 2 engagement and I expect to be using this partnership for several years.

PROS

Production system that has performed as specified since go-live without remediation work, documentation thorough enough to support internal maintenance, knowledge transfer that left our team genuinely capable

CONS

The quality of documentation they produce means our team needed to set aside dedicated review time to do it justice — a minor scheduling point rather than a genuine criticism

Questions & Answers

Please describe your company, your role, and the industry you operate in.
East Asia Commerce KK is an established Events & Event Management organisation headquartered in Osaka, Japan. My role as Head of Product Development covers both strategic planning and operational technology delivery. We maintain high standards for our vendors because our clients hold us to high standards — a bar we expect our partners to meet.
What specific problem or business challenge led you to hire this company?
We had a defined product vision for our next phase of growth in the Events & Event Management market but lacked the engineering depth internally to execute it. The Blockchain Development requirements in particular required specialist experience that we could not realistically recruit for on the timeline our business plan required.
What services did the company provide for your project?
The scope covered the full Blockchain Development lifecycle: discovery and requirements definition, solution architecture, iterative development across twelve sprints, integration testing, performance validation, production deployment, and a structured four-week hypercare period. They also provided system documentation and a knowledge transfer programme for our internal team.
Why did you choose this company over other providers you considered?
A trusted peer in the Events & Event Management sector had used them for a comparable Blockchain Development engagement and their recommendation was unequivocal. Our own due diligence confirmed the pattern they described. The combination of domain knowledge, Blockchain Development depth, and demonstrated delivery discipline was the deciding factor.
How clearly did the company understand your requirements and business goals?
Comprehensively. The discovery phase they ran was more thorough than anything we had experienced with previous vendors. They challenged requirements that were vague or contradictory, proposed alternatives where our initial thinking was limiting, and produced a functional specification that our internal stakeholders agreed was the clearest articulation of the product they had seen written down.
How was your overall experience with their communication and project management?
Communication was proactive, timely, and appropriately calibrated. Technical updates for the engineering audience, executive summaries for the steering group, risk flags with proposed mitigations rather than just problem statements. The fortnightly sprint reviews gave our stakeholders visibility without requiring them to attend every working session.
Did the company deliver the project on time and within your expected budget?
On time and within the approved budget. The estimation accuracy was notable — they had broken the work down in sufficient detail during discovery that their forecast proved reliable throughout, rather than being a number that shifted with every change in scope. We received one change request and it was for scope we had introduced ourselves.
What tangible results or business impact have you seen since the project was completed?
Quantifying the impact precisely is complicated by other variables in our business, but the metrics we can attribute directly to the Blockchain Development work are meaningful: session duration up, conversion rate up, error rate down, and our NPS for the digital touchpoint has improved by eleven points. Our account managers report that the new capability is coming up positively in client conversations.
What did you like most about working with this company?
The post-launch behaviour. Some vendors consider go-live to be the end of their professional obligation. This team treated it as the transition to a different kind of engagement. The hypercare period was substantive, the documentation was thorough and genuinely useful, and they checked in proactively at the thirty-day and ninety-day marks to review production metrics with us.
Would you recommend this company to others, and would you work with them again?
Yes, without reservation. I have already made two direct referrals within my Events & Event Management network — in both cases to peers facing Blockchain Development challenges similar to ours. I gave those referrals with confidence because I knew the experience I described was reproducible, not the result of exceptional circumstances on our engagement.

FAQs

What should I actually be looking at when comparing a company like RocketBuild to others?
When you're weighing up a software partner such as RocketBuild, it's worth looking past the pitch and checking the portfolio, what past clients say, relevant industry background, technical range, how they communicate, pricing structure, project management style, and what support looks like after launch. For context, its listed capabilities span Smart Contracts Audits, Unity 3D Game Development, iPhone App Development, Mobile App Design and Custom Software Development, and it has been operating since 2014.
Will RocketBuild sign an NDA before we even discuss the project in detail?

For context, its listed capabilities span Smart Contracts Audits, Unity 3D Game Development, iPhone App Development, Mobile App Design and Custom Software Development, and it reports a team size of 10 - 49 professionals.
Is RocketBuild more of an offshore setup or a local team?
That depends on where RocketBuild is based and who they primarily serve — some firms like this operate fully offshore, some are local-first, and plenty run a hybrid model that mixes both. For context, it has experience across industries such as Human Resources, Education, Events & Event Management, Sports & Fitness and Manufacturing, and its average project cost is reported at $25000+.
Roughly how long does a project with RocketBuild take start to finish?
It depends heavily on scope. A lean MVP might be a matter of weeks, while a full enterprise system or a larger digital transformation project can stretch into months once you factor in development, testing, and deployment. With a team of 10 - 49 professionals, RocketBuild can scale resources based on project urgency.
What's actually in RocketBuild's technical toolkit?
The exact stack shifts by project, but RocketBuild commonly works across things like React, Angular, Vue.js, Node.js, Python, .NET, Java, PHP, Flutter, React Native, native iOS and Android, and cloud platforms like AWS and Azure. For context, its listed capabilities span Smart Contracts Audits, Unity 3D Game Development, iPhone App Development, Mobile App Design and Custom Software Development, and it has experience across industries such as Human Resources, Education, Events & Event Management, Sports & Fitness and Manufacturing.

Its core focus areas include Smart Contracts Audits, Unity 3D Game Development, iPhone App Development, Mobile App Design and Custom Software Development.
What happens with RocketBuild after the project actually launches?
Like most established software teams, RocketBuild typically sticks around post-launch for ongoing maintenance — bug fixes, performance tuning, security patching, new feature work, and general technical support. For context, it has experience across industries such as Human Resources, Education, Events & Event Management, Sports & Fitness and Manufacturing, and it has been operating since 2014.
Has RocketBuild actually shipped a SaaS product before?
It's a common line of work for a company like RocketBuild — multi-tenant architecture, subscription billing hooked up properly, and cloud-native deployment built for a product meant to scale as a service rather than a one-off build. For context, its listed capabilities span Smart Contracts Audits, Unity 3D Game Development, iPhone App Development, Mobile App Design and Custom Software Development, and it has experience across industries such as Human Resources, Education, Events & Event Management, Sports & Fitness and Manufacturing.
Does RocketBuild only work locally, or take on clients elsewhere too?
RocketBuild isn't necessarily limited to one region and may take on clients across several countries, depending on market demand and business partnerships.
