ai developmentSPIE Belgium relied on spreadsheets, email, and five disconnected tools to coordinate 600+ field workers. Monterail replaced them with one AI-first platform, live in seven weeks at a fixed price. It now schedules the entire workforce in real time and frees up 100 hours of manual reconciliation every week.

staff augmentationMonterail grew its Go and QA team alongside Flink's own, from 2 developers to 11, as the quick-commerce startup opened new markets almost weekly. Adding a warehouse went from an engineering project to a routine operations task, and the backend kept pace as Flink reached 10 million customers across 60+ cities.

product designMerck needed a diabetes education app that would still load where 96% of users have no fixed broadband. Monterail designed and built it at 0.7 MB. It became Kenya's top destination for diabetes questions, then expanded to nine African countries and led to three more Merck projects.

llm integrationSimfoni's analysts spent hours manually turning billions of dollars in procurement data into client reports, one account at a time. Monterail developed Insights AI, powered by Claude on AWS Bedrock, to read the spend data and draft the report on its own. That work now takes one click, and Simfoni runs it at scale across its client base.

We moved from reactive scheduling to proactive, data-driven decisions. The ability to see a prototype in one day and scale it to an enterprise-ready solution so quickly was a game-changer for our resource management.
