// case study - Spekty
From an Excel file to a business platform running thousands of missions.
Spekty is a trusted third party in energy retrofitting. Its legacy Excel file could no longer keep up. ezacae designed a robust, scalable web platform to run the entire operation.
// context
Spekty is a key player in the French Energy Savings Certificates (CEE) scheme. Its network of field agents carries out inspections, surveys and verification missions - an operational chain that demands reliable, structured tools synchronised in real time.
// mission
- · Replace the legacy Excel file with a robust web app
- · Centralise missions, batches, stakeholders and reporting
- · Connect existing business tools (DMS, routing, emailing)
- · Tailored interfaces per profile: head office, field, quality, payroll
- · A single, secure cutover with no system overlap
// stack
- · Xano - backend API & business rules
- · WeWeb - multi-profile interfaces
- · Algolia - fast search across thousands of missions
// solutions delivered
A technical foundation built for scalability.
Understanding how Spekty "really" works
Before any development: take apart the Excel file and its macros, replay the teams' typical days, map the journeys of each profile. We didn't "put Excel in a browser" - we turned a legacy way of working into clear business journeys.
A Xano backend built for scale
Data modelling (batches, missions, agents, clients, surveys, payroll, statuses, history), APIs for the full lifecycle of a mission, automation of business rules, integration with existing tools, and Algolia for search across thousands of missions.
WeWeb interfaces centred on real usage
For support teams: a consolidated view of batch and mission status. For planners: route management. For field operators: mobile access to missions. For quality: dashboards and advanced search via Algolia.
A single cutover, with no operational disruption
Spekty chose to replace Excel in a single cutover, with no overlap period. Intensive testing on real data, cross-functional business validation - and on go-live day, the platform took over with no disruption to operations.
// results
Thousands of missions per month, under control.
Handles several thousand missions per month with no bottleneck Drastically reduces manual handling and the risk of error Each role gets a tailored journey rather than a single file A Xano / WeWeb architecture ready to absorb new volumes and clients
"We entrusted ezacae with the complete redesign of our internal tool for managing field interventions. The goal was ambitious: replace a complex Excel file with a modern, scalable web solution. The ezacae team understood our challenges perfectly. They modelled our processes, structured a robust backend on Xano, and integrated all of our tools. The versions delivered met our expectations exactly, with continuous quality improvements across the iterations. The platform they developed now lets us manage several thousand missions per month, with a centralised, reliable view and far fewer manual tasks."
