About us
We combine business understanding with technology and implementation.
Rhyline is a business engineering company in Basel, founded by Sebastián Ahumada. We help SMEs, growing companies and larger organisations understand what is really happening in their operations, and then we build what makes them work better.
Who you’ll work with
Before I built dashboards, I worked the floor they measure.
In Australia I started on the floor, as a farm hand on a greenhouse operation in Queensland and as a kitchen hand in a high-volume catering business in Melbourne. Harvesting, prepping, keeping pace with a live shift.
From there I built the performance management systems and Power BI reports that those same operations run on, connecting labour hours, costs and output in dashboards their managers use every day. That is the pattern behind everything I build: understand the operation first, then design the system around it.
Over more than nine years, that pattern has taken me across industries and countries: agriculture and catering in Australia, public infrastructure and industrial construction in Chile (Metro de Santiago and Arcadis), fleet and contract management for an industrial group, and an e-commerce website I built from scratch that grew a small business’s revenue by 35% in twelve months.
My background is Business Engineering with a major in Finance, so I look at a process the way a finance or operations manager does: what it costs, what it delivers and where the time goes.
I lead every project personally, from the first conversation to the final build. There are no account managers and no handovers between teams. The person who designs the solution is the person who builds it and stays with you after launch.
If your business has a challenge that doesn’t fit neatly into a category, I’d like to hear about it.

Business engineering
Understanding and delivery together, accountable from the first conversation to the working solution.
Build
- Data and reporting
- Automation and AI
- Software and platforms
A recommendation only creates value once it works in practice. Software only helps when it solves the right problem. We work on both sides: we understand the business question, and we have the technical ability to build and implement the answer.
How we approach every engagement
Whatever the size of the challenge, the sequence stays the same.
-
Understand the operation
How work really gets done, beyond the organisation chart.
-
Identify root causes
Symptoms are visible. Causes have to be found.
-
Simplify processes
Remove unnecessary steps before automating anything.
-
Structure data
Reliable information needs a reliable foundation.
-
Select appropriate technology
The right tool for the context, not the latest trend.
-
Build and implement
Working solutions, adopted by the people who use them.
-
Measure and improve
Track the impact and keep refining as the business evolves.
What you can expect
Business first
We start with how your organisation works, not with a technology.
Practical thinking
Solutions sized to the problem and built to be used every day.
Technical capability
We build and implement what we recommend, from data models to applications.
Accountability
We measure the impact of our work and take responsibility for the outcome.
Close to the work
Based in Basel, we learn how the work is really done from the people who do it, by video call, in a meeting or on site.
Accessibility
Direct communication, plain language and no unnecessary complexity.
Built on real operational experience.
