Accelerate your software design and development processes with services, products, and tools focused on achieving a shared vision and streamlining the mapping of functional software requirements into well-designed systems.
Avoid heavy frameworks. Adopt a modern, collaborative, and pragmatic software architecture approach.
Stuck with a monolith? Too many microservices? Wondering where to start tidying up your legacy code? Don't worry. We analyze your case and leverage our expertise to help you build an actionable plan moving forward.
A hybrid learning method that combines consultancy and training, ensuring knowledge retention through a hands-on approach and focusing on your specific technical and business cases. Let's analyze together your current software architecture's technical layout and processes and define a good plan to improve them.
Our books, the newsletter, and the blog compile a large amount of knowledge to learn at your own pace and stay on track with the latest trends in software architecture.
From technical topics such as event-driven, AI-assisted methods, Microservices, and Kafka to socio-technical subjects like collaborative decision-making, technical design facilitation, and visual system modeling. All are enriched with practical examples that enable your team to apply the acquired knowledge from the first day.
Forget about heavy, boring software architecture frameworks and processes that only create more distance between the software plans and reality. Learn how to use our simple, visual architecture tools designed to combine software architecture with Agile, Lean, XP, and other modern practices.
(Coming soon) Learn through practical exercises and live sessions focused on applying practical software architecture concepts to actual challenges faced by technical teams.
Why working with Mosy?
We don't throw canned software architecture statements and zero-value reports that include obvious conclusions to our clients. We roll up our sleeves and work side by side with your teams to craft solutions that fit your current business and technical contexts.
We focus on aspects beyond the technical quality of the architecture because we know that the challenges organizations face often stem from communication issues, decision-making processes, prioritization, and stakeholder management.
We prefer short projects that allow us to receive feedback and measure value within one or two weeks. This way, both you and we know if our software architecture consulting, training, or workshop is working, and can decide if we want to run further iterations.
We offer a toolbox of practical and visual techniques tailored to each specific case. Yet, we will not compel you to use specific tools or platforms; instead, we will help you integrate the patterns, not the particular apps, into your existing systems.
Design software systems without the hassle
Our freely available software architecture tooling includes multiple visual techniques and utilities to align teams on technical vision and principles, facilitate collaborative decision-making, build an architecture community, and more.
Diagnose your architecture problems interactively and get personalized solutions. From monoliths to microservices, security to scalability.

A startup entering the scale-up phase, but unable to scale its platform — and therefore its teams — due to a monolithic architecture.
Sympower, Energy Sector
~50 employees
Implementation of a visual, actionable architecture workflow strengthened stakeholder communication and enabled team restructuring. Complex components were abstracted behind APIs, reducing cognitive load and enabling the organization to scale beyond 100 developers.
Transforming a monolithic, client-replicated architecture into a scalable platform with reusable components.
Domain-Driven Design, pragmatic extraction plans, Anti-Corruption Layer, Strangler Fig Pattern, and Software Architecture Facilitation.
Improvised software architecture with decisions pulling in opposite directions. A hard-to-maintain monolithic integration layer caused team-collaboration issues. Lack of a clear technical vision to split B2C and B2B business strategies.
Dutch Fintech startup funded by ING
~70 employees
The legacy monolith was decomposed using a pragmatic approach, enabling parallel work. We applied Domain-Driven Design to place the B2C application as a client of the B2B platform, which allowed scaling the business.
Lack of technical vision and alignment across teams.
Architecture Community, B2B technical strategy, Microservices and Event-Driven architectures.
Helping organizations connect business and technology
Moisés Macero created Mosy in early 2025, after experiencing a recurring disconnect between business and technology visions in software development companies for over twenty years.
He applied all the lessons he had learned to develop new methodologies that combine effective and collaborative agreements with visual tools, helping organizations design better systems and processes without getting lost in theory or relying on outdated consulting approaches.
Knowledge in your hands
Real-world software architecture knowledge distilled into practical books. Learn tools, patterns, and distributed systems at your own pace.
All our tools and techniques are compiled in a comprehensive book that provides guidance, tips, and practical examples. Business-technical alignment, software architecture vision, technology adoption table, decision records, architecture community, and more.
A visual approach to modeling systems that fosters alignment across all disciplines by representing the different requirements of the software as multiple connected flows.
This book, now in its third edition, presents an evolutionary and practical approach to distributed software architectures. It helps you understand the challenges that arise when you transition from a monolithic system to a microservices-based architecture.
Learn how to build a full-reactive system from the database (MongoDB reactive) to the front-end (Angular), using a Reactive programming strategy leveraged by Spring WebFlux.
