Studio - Founder-led delivery

Software led by
senior judgment.

Ribbsaeter Systems is a senior engineering studio led by Patrick Ribbsaeter, a systems engineer and founder. We design, build and maintain distributed systems, AI infrastructure, agentic automation, and production software platforms.

The work is built for serious operators: technical depth with commercial context, clean architecture, deterministic validation, and direct founder ownership from first brief to production deployment.

Systems engineer.
Founder.

I'm Patrick, founder of Ribbsaeter Systems: a systems engineer, full-stack product architect, and founder operating across the complete software, AI, and digital technology spectrum.

While renowned for high-stakes systems engineering—including core open-source contributions to LLVM, Tokio, Apache DataFusion, Valkey, Meta Velox, and OpenAI Triton, paired with component-level physical hardware mastery—our studio is the go-to partner for end-to-end commercial product delivery: native and cross-platform mobile apps (iOS & Android), high-converting Next.js enterprise web platforms, custom SaaS architectures, and autonomous AI agent workflows.

We are technology-agnostic and industry-agnostic. From banking, fintech, and high-security transactional ledgers to healthcare, medical tech, e-commerce, real estate, and consumer internet applications—we operate with zero artificial boundaries on industry or technical scope.

We approach every project with founder-level ownership: senior-only execution, zero AI slop, deterministic quality standards, and deep technical rigor connected directly to business growth.

Where we work

Three European hubs,
one studio.

01

Zurich

Strategy & finance clients

Switzerland-rooted home base. Where premium engagements with private wealth, fintech and Swiss enterprise are coordinated.

02

Amsterdam

Design & product

Creative direction, brand systems and product design. Closest to the European startup ecosystem and design studios we collaborate with.

03

Eindhoven

Engineering & R&D

Brainport-region engineering hub for hardware-adjacent and AI-heavy work. Home to our R&D experiments and most demanding builds.

Our Values

What we stand for

01

Quality first

We refuse to ship work we wouldn't run ourselves. Every line of code is reviewed, every pixel intentional.

02

Direct communication

No account managers between you and the team building your product. You talk to engineers and designers directly.

03

Long-term partnerships

Most of our clients return — because shipping the MVP is just the beginning. We grow with you.

04

In-house only

We never outsource your work. Every contributor is a full-time team member with skin in the game.
