Business System Development

Business Systems,
Reinvented.

Business System Development. Fast, Cost-Effective & Flexible with AI.

Business system development has long been synonymous with high cost, slow delivery, and rigid systems.

MASSIVE LINKS is changing that with AI-Driven Development.

We deliver modern, flexible systems in half the time and at half the cost.

We build systems that teams actually keep using.

The Challenges

3 Challenges in Business System Development.

01Expensive
  • Major SIers charge tens to hundreds of millions
  • Mid-tier SIers start at ¥10M+
  • Additional requirements exceed budget
  • Running costs are also high

Out of reach for small and mid-sized companies

02Slow
  • 1–2 years from requirements to delivery
  • Business has changed by the time it's done
  • Competitors get there first
  • Significant opportunity loss

Can't keep up with today's business speed

03Inflexible
  • Requirement changes incur extra charges
  • Minor modifications take weeks
  • Post-launch improvements are difficult
  • Legacy issues emerge quickly

Outdated from the moment it's built

We solve all three with AI-driven development.

Failure Patterns

5 Common Failure Patterns in Business System Development.

01

Scope Creep Failure

Packing in every request from the field results in a system too complex to use.

Staff abandon it and go back to Excel

02

Schedule Delay Failure

Spec changes, technical issues, review delays… a 1-year plan stretches to 1.5 or 2 years.

Business has changed by the time of release

03

Budget Overrun Failure

Extra requirements, spec changes, bug fixes… an initial ¥10M ballooning to ¥30M.

Scrutiny from management

04

Unused System Failure

It's finished, but nobody uses it. "Hard to use" and "doesn't fit our workflow" are common complaints.

No return on investment

05

Legacy Failure

Three years later the technology is outdated and both modifications and maintenance become difficult.

Rebuilt from scratch all over again

MASSIVE LINKS prevents all five of these from the start.

What is AI-Driven Development

A development methodology that leverages AI tools such as ChatGPT, Claude, and GitHub Copilot to streamline the entire development process. Rather than code written by humans alone, it embodies a new approach where AI proposes and humans judge and refine.

Legacy Renewal

Legacy System Renewal.

Legacy System Challenges

  • Systems that have been running for 10+ years
  • Difficult to modify (siloed knowledge, lack of documentation)
  • Maintenance vendor has withdrawn
  • Security risks
  • Too costly to add new features

MASSIVE LINKS Legacy Renewal Approach

01

Current System Analysis

Analyze functions, data, and workflows of existing systems (AI-assisted reverse engineering also available)

02

Phased Renewal Plan

Renew module by module rather than all at once, minimizing risk and impact

03

Parallel Operation

Run old and new systems in parallel for a period, ensuring a safe cutover

04

Modern Replacement

Rebuild with the latest tech stack, designed with the next 10 years in mind

Common Renewal Targets

On-premise core systems → Cloud-native

VB6, Access, legacy Java → Next.js + TypeScript

Monolithic apps → Microservices

Excel-based workflows → Web systems
