Case Studies

With AI and data,take your business further.

Have you introduced AI only to find that it is not delivering? Realising the full value of AI and data requires everything from understanding the business and developing algorithms to system design, engineering, testing, security and operations. We support the entire journey.

What We Do

What you can hand to us, and how far.

Rather than labelling ourselves an "AI company", we organise our work by the business problems you can bring to us.

Data & Algorithm

Data analysis and algorithm development

From analysing business data to demand forecasting, recommendation and price optimisation — validated not only for accuracy but for whether it can keep running.

  • Data analysis
  • Demand forecasting
  • Recommendation
  • Price optimisation
  • Machine learning
AI Product

AI product development

Turning generative AI, image, video and voice models into products that hold up in day-to-day operations — not one-off demos.

  • Generative AI
  • LLM applications
  • AI interviews
  • Image & video AI
System Engineering

System design and engineering

Web, API, CMS and data platforms — plus analysis and improvement of the systems you already run.

  • Web / API
  • CMS
  • Data platform
  • Legacy system improvement
Reliability & Security

Quality, security and operations

Testing, monitoring, cost optimisation and vulnerability assessment. We design for what happens after launch.

  • Test design
  • Monitoring & logging
  • Vulnerability assessment
  • Cost optimisation
  • Operations

Selected work

Projects where we owned the work end to end — from understanding the business to running it in production.

CASE 01RECOMMENDATION

Recommendation at a scale of hundreds of millions of records

Change what you offer to whom, and the outcome changes.

What looked like the problem

Improve recommendation accuracy.

What the real problem was

Decide the ordering that maximises business outcome within a fixed number of slots.

Business Challenge
Serve the right offer to each user and maximise results within a limited number of recommendation slots.
Approach
We compared multiple machine learning approaches — DNN, matrix factorisation, GBDT and regression models — testing not only accuracy but whether each could keep processing large volumes of data continuously.
System
A recommendation system processing hundreds of millions of records.
Result
CVR improved by 1.5× without increasing the number of recommendations shown.

Designed around processing speed, data refresh and operational load — not accuracy alone.

CASE 02BEAUTY

Price and campaign optimisation for aesthetic clinics

Before you change the price, understand why people come.

What looked like the problem

Calculate the optimal price.

What the real problem was

Understand why, and when, someone decides to come back for another treatment.

Business Challenge
Optimise pricing and campaigns according to booking status and customer behaviour.
Approach
We analysed visit cycles, treatment history, price response and booking status — and designed around the actual customer experience and on-site workflow, not the data alone.
System
Owned end to end: EDA, consulting, algorithm validation, system development and operations.
Result
A dynamic-pricing campaign generated an additional ¥1.5 million in monthly sales, reaching 1.7× the previous level.

Our analyst used the service directly, following the customer experience from booking through consultation, treatment and the return visit, before designing the system.

CASE 03CRM

Analysis and improvement of a large-scale CRM system

Not only building new systems — making the existing one stronger.

What looked like the problem

Rebuild the system.

What the real problem was

Make visible where cost and risk have accumulated inside the system you already run.

Business Challenge
Review cost, architecture, defects and security across an existing system.
Approach
AI-assisted code analysis combined with human architecture review to take stock of the whole system.
System
Cost reduction proposals, defect fixes, design improvements and security improvements.
Result
Cost, quality and security improved together — without taking the running system down.

We start by identifying what can be improved in place, rather than assuming a rebuild.

  • Cost reduction
  • Defect fixes
  • Design improvements

CASE 04HR

AI interview system

An AI that can talk is not yet a business system.

What looked like the problem

Have an AI conduct the interview.

What the real problem was

Build something where candidates can complete an interview with confidence and companies can manage the results safely.

Business Challenge
Candidates needed to interview regardless of place or time, while the company needed to manage everything securely.
Approach
We designed for recording, the admin console, permissions, failure behaviour and vulnerability response — not just the quality of the AI's responses.
System
AI interview + recording + admin CMS + permissions + incident response + security.
Result
Ongoing ownership from design and development through maintenance and vulnerability response.

The system is designed around the candidate's experience and the company's operations, rather than placing the AI model at the centre.

CASE 05GENERATIVE AI

AI video production platform

From a tool that generates once, to a production system.

What looked like the problem

Generate high-quality video.

What the real problem was

Let people who don't know video production handle the production process.

Business Challenge
Move generative AI beyond one-off output into something usable as a production process.
Approach
We designed image generation, upscaling, editing, video generation and asset management as a single production flow.
System
A platform covering image generation → upscaling → editing → video generation → management.
Result
An environment where the whole production process can be handled without specialist knowledge.

Designed on the assumption that work in progress must be preserved and steps must be repeatable — not just that output looks good.

How We Build

Not "it works" — "it can be used".

This is how we build. Where most teams write QA, we write Break.

  1. 01

    Understand

    Understand the business and the front line

  2. 02

    Design

    Design for the scale it will reach

  3. 03

    Build

    Build fast, with AI in the loop

  4. 04

    Break

    Work through every scenario we can think of

  5. 05

    Observe

    Check the data, the logs and the monitoring

  6. 06

    Improve

    Keep improving from real operation

Testing

Working today is the baseline. It must keep working ten years from now.

We don't only confirm the happy path. We enumerate and verify the scenarios that actually happen: dropped connections, abandoned sessions, duplicate submissions, malformed input, concurrent operations.

And we don't stop at what the screen shows — we check the state inside the system: the database, the logs, the storage.

Visible

What the screen shows

  • UI
  • A successful response
  • A completion message

Behind the UI

What we check behind it

  • Stored data
  • Duplicates
  • Errors
  • Permissions
  • Logs
  • Cost
  • Security
Security & Operation

Stable systems. Operations you can trust.

Release is not the finish line; it is where operation begins. Failures, abuse and cost all show up once the system is live.

Monitoring

Detect anomalies before a person notices

Logging

Keep what happened traceable after the fact

Permissions

Show it only to the people who should see it

Vulnerability assessment

Break it ourselves, from the attacker's side, first

Data durability

Design so nothing is lost when things go down

Backup

Verified all the way through to restore

Cost monitoring

Keep growth in usage from becoming growth in the bill

Continuous improvement

Keep fixing based on how it is actually used

Technology is a means.

Start from the business problem, not from adopting AI.

You don't need firm requirements. These are all good places to start:

  • We don't have enough people
  • We have data but aren't using it
  • Our existing system costs too much to run
  • We built an AI but can't run it in production
