Discover Ars MemorandiThe company behind the products
Ideas into Intelligent Software.
We develop independent software brands that transform ideas into meaningful digital experiences.
Our portfolio brings together brands for memory, learning, performance, the mind, family safety and everyday life — each built for its own audience.
Who we are
We build software with purpose.
Walraven Labs is an independent software company focused on creating and developing distinctive digital products.
We turn ideas into intelligent software experiences designed around real people, specific needs and practical applications.
Our portfolio brings together independent brands across memory, learning, performance, the mind, family safety and everyday life.
Our focus
Software for the mind.
Most of our products share one domain: the human mind. Memory and the art of remembering, learning, performance, imagination, perception and the work of practitioners who help people — fields where well-made software can change how people learn, remember and feel. Alongside them, PRAESTO helps families prepare for emergencies and MECUM makes sure nobody leaves home without what matters.

What drives us
Four principles behind every product.
- 01
Purposeful innovation
We build what solves a real problem for a defined audience — not features for their own sake.
- 02
Human-centred technology
Software should be understandable on first use and comfortable for people of every age and skill level.
- 03
Intelligent software
We apply AI and smart systems where they make something genuinely easier or better.
- 04
Continuous development
A launch is a beginning. Products are tested, refined and expanded over time.
How we build
From idea to product.
- 01
Discover
Understanding the opportunity, audience and problem.
- 02
Design
Creating the experience, architecture and product identity.
- 03
Develop
Building functional, scalable and reliable software.
- 04
Improve
Testing, learning from users and refining the product.
Technology
Technology with a human purpose.
We explore how software, artificial intelligence and thoughtful digital experiences can create practical value.
Our products share one technical foundation where that makes sense, while each keeps its own data and functionality.
Areas of focus
- AI & intelligent systems
- Software architecture
- Human-centred design
- Digital experiences
- Automation
- Privacy & security
These are the fields we work in. Each product uses only what serves its purpose.
