The fintech space is moving fast. With increasingly demanding users and an ever-growing digital ecosystem, building financial products that are efficient, scalable, and deliver a great user experience is essential.
From global inspiration to proven success stories
At Somnio, we partner with fintech companies to meet the industry's expectations with speed and precision, developing high-performance apps that work seamlessly across mobile and desktop.
In a previous blog, we looked at how global leaders like Google Pay, Nubank, ING, and Crédit Agricole reimagined their platforms to meet modern demands. Today, we’re sharing how Siigo, one of the largest business software providers in Latin America, scaled and modernized its financial suite with the help of Somnio’s strategic support.
Siigo's transformation: Built with purpose
Siigo needed to modernize its infrastructure, launch next-gen financial products, and improve user experience without compromising operational stability. Their goals included delivering a new restaurant-focused POS system, creating a user-friendly ordering app (Siigo A la Orden), and migrating their ERP (Siigo Nube) to a modern, unified architecture.
The key was to build a solution that combined performance, scalability, and seamless user experience, all within a single tech stack.
Our approach at Somnio
We don’t just code, we co-create strategic digital products with our clients. With Siigo, we used a phased, collaborative process:
- We designed and built the new POS and ordering app using a cross-platform approach, enabling faster iterations and a consistent experience across devices.
- We migrated Siigo Nube to a single codebase optimized for both web and mobile.
- We integrated deeply with their existing infrastructure to ensure continuity and smooth rollouts.
- We focused heavily on UX/UI, designing intuitive features that made everyday use easier and more enjoyable for users.

Real Impact
The results were clear:
Faster development cycles and improved team productivity led to consistent performance and design across both desktop and mobile platforms. Backed by a solid architecture, the solution is built to scale and support future market expansion, guided by a clear roadmap that keeps Siigo at the forefront of fintech innovation.
