Our history
onSedi has always combined the technical excellence of its team with the most innovative technological developments to remain one of the leading companies in expert and architectural solutions, driving the maintenance, improvement, and/or rehabilitation of properties.
2012
onSedi was founded under the name Ingenium Propietarios, a company specialising in the maintenance of real estate assets through its line of technical architectural solutions, but with a vision that clearly prioritised technological developments in the property services sector.
2013
We expanded our portfolio by incorporating expert solutions and establishing ourselves as a specialised property consultancy.
2014
Technological developments were launched to digitise the execution of our solutions as a key differentiator, with the clear goal of streamlining and reducing the cost of all processes while simultaneously improving quality.
2015
We became the provider of expert solutions for Mutua de Propietarios, Spain’s oldest property insurance specialist.

onSedi breaks two major records: completing over 50,000 video assessments and issuing more than 500,000 expert reports.
The company collaborates in the implementation of the RER Plan for the energy rehabilitation of residential buildings, financed by the European Investment Bank (EIB) and the European Commission’s ELENA programme.
Additionally, onSedi inaugurates the Badía del Vallès Technical Rehabilitation Office, acting as a Rehabilitator Agent and preparing building records and improvement projects.
2024
onSedi strengthens its presence in Madrid, increasing billing in the city centre by more than 80%.
