Upgrade the software you already have
Scale an app you already run, get an AI-built app past the demo, or modernize a legacy system. One senior team for all three.
Scale an app
Scale an existing app
A Dedicated Team for the app you already run. Keep what works.
You already have something working. You need features, performance, redesign, or scale. We join your team and deliver. Taking over code another team wrote? We start with an App Review, so you know what we found before you commit.
Who this is for
- Customers are asking for features your team can't get to
- The app works, but it's slowing down as you grow
- You need senior people to join your team, without a long hire
What we plug in
The app you already run, plus a senior team.
-
Architecture & Design
System design and a technical plan for what comes next.
-
Feature Development
New features across web, mobile and enterprise systems.
-
QA & Automation
Manual and automated tests, wired into your CI/CD.
-
UX / UI Redesign
Research, wireframes and new screens built to your design system.
-
Performance & Scale
Database tuning, caching and load handling.
-
AI Pipelines
Model integrations, retrieval, and text, image and video processing.
How it runs
-
Get to know your code and your team
We learn how the app is built, how your team works, and what matters most to change.
-
Start with an App Review
A free assessment of your app: a written report, a prioritised fix list, and a quote for us to take it over, based on scope. See the App Review.
-
Work alongside your team
Senior leads in Tokyo and the US run the project, our engineering team in Vietnam builds, and the team grows or shrinks with the work.
-
Full visibility, all the way
Our project system tracks progress at the feature level, with estimates against actuals, so you stay in control of scope, priorities, and budget.
Vibe coding
Hit the limit with vibe coding?
Built it with Lovable, Bolt, Cursor, Replit or ChatGPT and got stuck? AI tools get you to a working demo fast. Real users, real data and real money are where it starts to break. The first step is an App Review: a written report, a prioritised fix list, and a price for us to take it over.
What breaks after the demo, and how we fix itLegacy systems
Modernize a legacy system
Keep the business rules. Move the code to a modern stack.
If the business still runs on VB6, PowerBuilder, Classic ASP, Access or something similar, the rules it follows often live only in that code. We carry those rules over, so nothing the business depends on is lost. The work is delivered under Vivify, our modernization brand.
- VB6
- PowerBuilder
- Classic ASP
- Access
- COBOL
- RPG
- Oracle Forms
- Delphi
- .NET WebForms
How we do it
What every project gets, whether you digitize, launch, or upgrade.
Reusable infrastructure
Sign-in, messaging, data, payments, and real-time, proven in production for more than a decade. We reuse what's solved and spend the effort on what makes your product different.
Design-led thinking
Design comes before code. UX research and wireframes first, so what we build is something people want to use.
Security built in
Access controls, audit trails, and careful data handling from day one, with the discipline of our HIPAA-ready healthcare work on every project.
AI-accelerated delivery
AI handles the repetitive work. Senior engineers check everything it produces, security included.
Senior experience
Since 2014, senior leads in the US and Japan have run every project. They know where software projects go wrong, so you get fewer surprises.
Capacity when you need it
When the work grows, our extended team in Vietnam and specialists in Europe and South America add capacity. Your lead stays the same.
Common questions
Do we have to move to your platform?
No. We build within your stack, and the code and IP stay yours.
Can you work with our existing developers?
Yes. We start by getting to know your code and your team, and we work alongside them.
How is it priced?
As a Dedicated Team: half-time, 1 developer or 2 developers, with a lead, project management and QA included. A fixed price is also possible when the scope is clear. See pricing.
Can you take over an app another team built?
Yes. Start with an App Review, so you know what we found and what it costs before you commit. Kenzai came to us after running its own app cost more than made sense for the business; we have run its app since 2019.
Our system is decades old. Is this the right service?
Start with Modernize. Vivify, our modernization practice, converts the legacy code, and we build on the result.
