AI-First Resource Management Tool for SPIE Belgium

SPIE Belgium had outgrown the patchwork of off-the-shelf tools managing its workforce. Disconnected systems, manual data reconciliation, and a lack of real-time visibility into field workers' availability were creating constant operational friction. Monterail delivered a custom, AI-first web platform in a 7-week fixed-price engagement. We replaced a fragmented SaaS combo with a single owned solution integrated directly into SPIE's internal systems.

Highly recommended

Our customers love Monterail’s design. They praise the app for being performant and super-slick. Even though we’re based in Atlanta and the pace of development is crazy, we never had any communication issues with the team in Wrocław. I wouldn’t hesitate to introduce Monterail to anyone.

Aligning technology with business

Working with Monterail's experts was valuable because we focused on the final product rather than on singular elements. Together, we built the best solution possible. It's a reminder that developing great digital solutions isn’t solely about writing proficient code – it’s about aligning technology with business.

How Monterail Built an AI-Powered MVP for a Smart Walker Senior Mobility App

Camino, a California startup, set out to build the first AI-powered smart walker for senior mobility. Monterail built the native iOS app and the Wi-Fi/BLE connection linking it to the walker hardware, tracking metrics for physical therapists and family caregivers, while the gamification features kept elderly users engaged. Discovery workshops and clickable prototypes shaped the design before development started. The project shipped as a working MVP and hardware-software prototype.

How Monterail Built Joii's AI-Powered Menstrual Health App Reaching 99% Scanner Accuracy

Joii, a Dublin-based femtech startup, wanted to turn photos of used period pads into quantified health data: flow volume, clot size, and cycle trends. Monterail built the iOS and Android app in Hybrid Flutter and developed a real-time image-analysis scanner that reached 99% accuracy, measuring flow volume in milliliters from a single photo. The app launched in 2025, is free on both platforms, and holds Class I Medical Device certification in the UK.
