Quiet systems for work that must last

Makasu designs and builds custom, data-centric software systems for organisations that have outgrown spreadsheets, fragmented tools, and generic SaaS.The focus is not on features or trends.
The focus is on structure.
Makasu systems are designed to support daily operations, reduce noise, and remain calm under growth.

When software no longer fits

Most organisations don’t fail because they lack software.
They fail because their software no longer fits.

  • Spreadsheets become fragile systems.

  • SaaS tools multiply and overlap.

  • Critical data is scattered.

  • Processes rely on memory and workarounds.

Over time, the system itself becomes the problem.


What Makasu does

Makasu designs coherent internal systems that replace fragmentation with clarity. This includes:

  • Designing the underlying data model

  • Structuring workflows around reality, not theory

  • Building software that reflects how the organisation actually works

The result is not an “app”.
It is a working system.

Who this is for

Makasu works best with organisations that:

  • value clarity over novelty

  • prefer systems that last

  • want fewer tools, not more

  • understand that good software should feel calm

If you are looking for fast experiments, constant reinvention, or off-the-shelf answers, Makasu is not a fit.


Start with clarity

The first step is not a build. It is a conversation about structure.A System Clarity Session is a focused engagement to understand your workflows, data, and constraints — and to determine whether a custom system makes sense.

View the Makasu approach

The Makasu Approach

Makasu does not start with tools, features, or automation.
The work starts with:

  • Real workflows

  • Real constraints

  • Real data

Only then does software enter the picture.


01

System mapping

Existing workflows are mapped as they truly exist — not as idealised diagrams. This includes:

  • How work actually flows

  • Where decisions are made

  • Where data is created, changed, and lost

Ambiguity is made explicit before anything is built.

02

Data architecture

A clear data model is designed. This defines:

  • Entities and relationships

  • States and transitions

  • Responsibilities and boundaries

The data model becomes the backbone of the system.

03

Focused build

The system is built with restraint. Priorities are:

  • Clarity over cleverness

  • Performance over decoration

  • Durability over speed

Every element must justify its existence.

04

Long-term stability

Systems are expected to change. They are not expected to decay.Changes are introduced deliberately, without eroding structure or introducing noise.

Why this matters

A system that is well-designed:

  • supports daily work without friction

  • reduces operational noise

  • makes decisions easier

  • fades into the background

That is the goal.

What Makasu builds

Makasu designs and builds custom internal software systems.Typical systems include:

  • Internal CRMs and client management platforms

  • Operations and administration systems

  • Compliance, legal, and case management tools

  • Project, asset, and documentation tracking

  • Bespoke back-office systems SaaS cannot model

Each system is designed around the organisation’s specific data and workflows.


What custom means here

Custom does not mean:

  • Unlimited features

  • Visual complexity

  • Constant change

Custom means:

  • The data model fits

  • The workflows match reality

  • Unnecessary elements are removed

The system exists to support work — not to impress.

What these systems replace

In most cases, a Makasu system replaces:

  • Multiple spreadsheets

  • Overlapping SaaS tools

  • Manual coordination

  • Undocumented processes

The result is fewer tools, not more.

What you will not get

Makasu does not deliver:

  • Generic templates

  • Dashboards for their own sake

  • Feature overload

  • Experimental software

The work is deliberate and bounded.


Discuss your system landscape

Not every problem requires custom software.
That is determined before anything is built.

Read about the person behind Makasu

The person behind Makasu

Makasu is led by Marcus Stiehler, system designer and software architect with nearly two decades of experience designing and building custom business systems.His work focuses on:

  • Internal software for complex organisations

  • Long-lived systems that must remain stable

  • Data-centric architectures that support real operations

Makasu exists to apply this experience with restraint.


Experience, briefly

Marcus has designed and built systems across:

  • Legal and compliance environments

  • Finance and operations

  • Enterprise and SME contexts

The emphasis has always been on clarity, structure, and durability.

Certifications and tooling

Marcus is a certified Claris FileMaker™ developer, holding official professional certifications. These represent:

  • Verified technical competence

  • Long-term platform experience

  • The ability to build production-grade systems

They do not define the work — they support it.Makasu designs systems independently of trends or tools.Most systems are built using FileMaker, chosen for its relational strength and long-term durability in internal environments.The system determines the tool — not the other way around.

Working together

Makasu is intentionally small and focused.Work is done directly, without layers, and with clear responsibility.If this approach resonates, the next step is a conversation.

System Clarity Session

The System Clarity Session is a focused conversation to understand your current workflows, data, and constraints — and to determine whether a custom system is the right solution.This is not a sales call.
It is a structured analysis of your situation.


What the session is

During the session, we look at:

  • How work currently flows through your organisation

  • Where data is created, duplicated, or lost

  • Which tools are compensating for missing structure

  • Whether simplification or custom software makes sense

The goal is clarity, not commitment.

What you will get

After the session, you will have:

  • A clearer understanding of your system landscape

  • An assessment of whether custom software is appropriate

  • An outline of possible next steps (or confirmation that none are needed)

In many cases, this alone removes weeks of uncertainty.


Practical details

  • Duration: 60 minutes

  • Format: Video call

  • Preparation: Brief written context (via the form below)

The session is intentionally limited and focused.

Calm positioning note (important)

Not every organisation needs custom software.
That is determined before any build is discussed.
If Makasu is not the right fit, you will be told so directly.


Request a System Clarity Session

Please provide a short overview of your situation. This helps determine whether the session is appropriate and ensures the conversation is focused.

Thank you.

Your request for a System Clarity Session has been received.


What happens next

Your submission will be reviewed personally.The goal at this stage is not scheduling — it is fit.If a System Clarity Session appears appropriate, you will receive a reply with:

  • Confirmation

  • Available time options

  • Any brief follow-up questions, if needed

If it is clear that a session would not be useful in your situation, you will be told directly.

A note on timing

You can expect a response within 1–2 business days.Makasu is intentionally small and focused.
Requests are handled carefully, not automatically.
