PropTech start-up Sitowie raises €1.7M to revolutionize predictive building maintenance

Sitowie, a predictive maintenance solution for greater sustainability and improved environmental performance of buildings, announces a €1.7M seed round with PRVF managed by Karista, Paris Business Angels, Femmes Business Angels, WinEquity, and Unico. Objective: better fight global warming while improving the financial performance of real estate assets thanks to an innovative and user-friendly SaaS platform.

This first round of funding will allow the Paris-based start-up to speed up its development. Sitowie’s ambition is to work hand in hand with building asset owners and asset managers to anticipate the aging of their assets, make them more sustainable and profitable, and reduce their carbon footprint. Sitowie already supports a wide range of clients: social housing owners, local authorities, real estate companies and property managers are all looking for more rationalization in their planning.

Founded in 2018 by Pauline Koch – an architect and a graduate of the École des Ponts ParisTech – the Sitowie team counts 15 people with high-level technical and scientific backgrounds (PhDs in Modeling and Simulations, Materials Sciences, CivilEngineering, etc.). Yann Lefeuvre is leading the R&D team and brings more than 20 years of experience in the construction industry.

Smart building and aging: a key topic for the industry

Aging well is not only a people matter but also does concern buildings. The real estate industry is finally realizing that maintenance of a real estate portfolio is a key challenge to improve the assets’ performance.

Yet, many asset owners and property managers are blind when it comes to manage their portfolio. How should I allocate my budget? How elaborate maintenance and renovation plans well aligned with my business plan? Will the plan bring the expected savings and ROI? How manage both financial and environmental performance?

Many questions with no straight answers because asset management costs are often poorly evaluated, with no use of available data, and BIM still an expensive and hard to use tool.  

Predibat by Sitowie

Sitowie offers real estate owners and property managers, regardless of their digitization process, a predictive SaaS to improve building maintenance, make wise investment decisions, and define the best strategy.

Sitowie SaaS platform (Predibat) is an asset strategy management tool that allows, from clients’ existing data, to automatically generate a technical repository and simple IFC models in a user-friendly environment. The data sets are enriched with open data. Sitowie structures and centralizes all the information. Users can:

  • Generate in a click a simple digital twin of an asset, sufficient in the decision-making process for a streamlined management of the portfolio;
  • Visualize the status, risks, deterioration scores and their evolution;
  • Geta predictive view of maintenance works by element, asset and across all the portfolio;
  • Optimize master plans (OPEX / CAPEX), follow maintenance and renovation plans, and monitor investments and budget.

Sitowie brings a unique solution to the whole real estate industry; extend the life span of real estate assets allows to:

  • Contribute to the fight against global warming: Sitowie reduces the carbon footprint up to34% and is now developing solutions to reduce energy consumption. Extending the life span of an asset helps to reduce its carbon footprint and better monitor energy consumption. Timing is perfect as regulations are stricter in Europe, the industry is currently experiencing a shortage of materials, and energy consumption of real estate assets is a hot topic;
  • Improves the financial performance of real estate assets: Sitowie is a predictive maintenance software that generates up to 35% savings on work plans and maintenance costs.

Sitowie’s product also offers an easy-to-use and cost-effective solution to digitize, structure and centralize building data. First customers’ feed backs show a 25% gain in productivity thanks to the automatic generation of a technical repository, quick visualization of risks, optimization of investment plans, and dashboards to monitor the plans.

"Real estate professionals must quickly act for the planet and their assets. The construction industry is a major contributor of energy consumption and is responsible for 43% of French energy consumption. Every year, the sector generates more than 120 million tons of greenhouse gas emissions (about a quarter of French total emissions) according to the Ministry of the Environment. There are now reliable and efficient solutions to make our buildings more sustainable and profitable. It is even more true in the materials shortage we’re experiencing. Let's do it!" says Pauline Koch, CEO of Sitowie.

"The building and construction industry is the largest contributor of CO2 emissions, but few solutions address the existing stock and the full life cycle of a real estate asset. Sitowie's solution is at the heart of the industry’s challenges: making buildings more sustainable, planning rightly, and monitoring maintenance costs that can account up to 80% of total costs. We are proud to support Pauline and Sitowie in this ambitious project." concludes Benjamin Zerbib from Karista.

The company has also strong support from real estate professionals:

  • Christian Cleret, Honorary President of ADI, co-Chairman of the RBR 2020-2050 Plan Bâtiment Durable Group;
  • Philippe Jouan, President of Jouan & Associés, former President of RICS France;
