Let’s talk about your business.

Scale your business without technology slowing you down.

I identify where software, team capacity or engineering costs limit growth and lead the changes needed to scale.

Let’s talk about your business.

I’m Matthias Isler, fractional CTO, founder and engineer. I connect the economics of your software business to the architecture and team making it work.

Where does growth become expensive?

Each customer creates more manual work. The platform struggles under demand. Engineering spend rises faster than useful capacity. Conflicting data makes the cause difficult to see.

Hiring more developers will not fix a production model that creates unnecessary work. More infrastructure may only make an inefficient application more expensive.

More customers or higher service volume

Software, team, workflow, data or cost constraint

Targeted investment or simpler operating model

More useful capacity at sustainable cost

Remove the constraint before expanding it.

Ownership02

Remove the constraint that matters

I trace the intended growth through software, data, workflows and people. Then I lead the relevant changes: simpler scope, a stronger platform, missing skills or automation that changes the cost of serving a customer.

We measure the consequence—processing cost, release reliability, rework or workflow capacity—rather than treating more activity as progress.

Proof03

Client work · Software development agency

Change the production model before adding people

A software agency had frustrated customers, developer turnover and outsourced work it could not control. I owned the strategy and execution of replacing that production model with an internal engineering team. We connected ownership to contribution and used AI to automate repeatable work.

Read the production-model case.

Contribution-linked ownership and AI-assisted production

Monthly employee-engineer salary averages over a few months before and after, at comparable work volume and complexity.

Engagement04

How I work with you

I can join as fractional CTO or lead a focused Platform Engineering, Team Development, Automation or Data And Analytics assignment. Your developers or suitable partners implement the work under my leadership.

CTO mandates start at

CHF 3'500per month

We agree the scope individually. Focused assignments are quoted separately.

Execution. Economics. Choosing the arrangement.

Questions05

Does growth require a rewrite—or AI?

Only where the constraint warrants it. A targeted improvement or simpler service may be enough. I assess AI investment against useful output, data, human judgement and running cost. A wider transition belongs in a modernisation plan.
