He turned to Didier Fornetti, CTO of Santiane (another company founded by Christophe), to help design a comprehensive management tool. That tool enabled Flex-O to grow rapidly, remain independent, and achieve profitability.
Four years on, Flex-O stands as:
- 17 sites across major metropolitan areas
- 60,000 m² of managed spaces
- Over 2,000 clients
- An independent and highly profitable operator
After four years of R&D, testing, and daily optimisation alongside one of France’s leading coworking operators and one of its most dynamic and with the arrival of Brice Arnavon, SaaSOffice was born: an all-in-one software platform designed to revolutionise the management of coworking spaces and flex offices. This solution led to the creation of an independent company in early 2024.
The Birth of SaaSOffice
Flex-O’s success was not solely built on creating attractive, eco-responsible workspaces. It was made possible by deep technological thinking. From the outset, Christophe Courtin understood that the key to scaling a coworking operator lay not only in the location or design of the offices, but in the ability to efficiently manage every aspect of the business.Together with Didier Fornetti, they decided to build a solution that did not yet exist on the market: an all-in-one, modular platform purpose-built for space operators. After proving its value internally at Flex-O, the solution was structured as an independent company.
That is how SaaSOffice came to life, with a clear ambition: to offer operators a single, secure, and fully integrated platform, enabling them to scale with confidence.
Julien Fritz, former Head of Operations at Flex-O – « When we first launched the software, we immediately noticed a real shift in our organisation. The operational management of our spaces became far smoother thanks to the centralisation of information and the automation of numerous tasks. Having unified data allowed us to eliminate the use of multiple tools and avoid double data entry, resulting in significant time savings, greater efficiency, and cost reduction. It also enabled us to better track our performance indicators, more easily identify upsell opportunities, and optimise space occupancy rates. Very quickly, our teams were able to focus more on client relationships, which had a direct impact on satisfaction and retention. »Learn more
How SaaSOffice is redefining software solutions for coworking
An All-in-One Coworking Software
The coworking and flexible office market is booming. But this growth comes with a challenge: management complexity. Most operators still juggle multiple tools CRM, invoicing software, access control systems, marketing platforms that communicate poorly with one another, or not at all. This fragmentation slows decision-making, generates errors, and inflates costs.SaaSOffice fundamentally changes the equation. Its strength lies in its ability to deliver end-to-end management of the entire value chain:
- Acquisition: tracking of inbound leads, scoring, qualification, and automated nurturing.
- Sales: a clear commercial pipeline, quote generation, and closing cycle integration.
- Contracts: integrated generation and electronic signature, amendment and renewal management.
- Spaces and options: granular management of private offices, coworking desks, meeting rooms, and additional services (parking, concierge, catering, etc.).
- Invoicing and payments: real-time tracking, automatic invoice generation, seamless accounting integration.
An Optimised Client Experience
On the client side, SaaSOffice offers an intuitive application that centralises every aspect of the relationship: contracts, room bookings, option additions, invoices, and communication with the operator. The coworker becomes an active participant in their own experience, with a level of modularity never seen before on the market.
It is this dual promise, a powerful back office and a seamless client experience that positions SaaSOffice as the next-generation software for flexible space operators. Request a demoSaaSOffice: A Strategic Decision-Making Tool
Data-Driven Strategic Decisions
A coworking operator faces an endless stream of micro-decisions every day: should the price of a private office be adjusted? Should investment go into a new marketing campaign? Should a contract be extended or a vacant space reassigned?
Traditionally, these decisions were based on Excel spreadsheets laboriously compiled from disparate data sources. With SaaSOffice, all of this information is centralised and available in real time.
Each department can access its key indicators without delay:
- CEO: quickly identify which centres are underperforming and understand why (location, pricing, services, competition).
- CFO: know the exact acquisition cost per marketing channel, enabling intelligent budget allocation.
- COO: optimise occupancy rates, anticipate demand peaks, and adjust per-m² pricing.
- CCO: analyse which services generate the most recurring revenue (parking, meeting rooms, catering) and strengthen the most profitable offerings.
- CMO: measure the ROI of digital campaigns in real time and adjust marketing investments accordingly.
- Head of Sales: monitor sales team performance and verify whether the pipeline is on track to meet quarterly targets.
From Operations to Strategy
By centralising this data, SaaSOffice does more than simplify management, it becomes a genuine strategic decision-support tool. Executives gain in both responsiveness and confidence, two essential qualities in a market where speed of execution is paramount.This operational intelligence also enables better forward planning: expansion into new cities, the launch of new services, or more informed real estate arbitrage.
SaaSOffice: A Company in Its Own Right
Independent Governance
Although born within Flex-O, SaaSOffice quickly established its independence. Today, the company operates as a distinct entity, with its own governance structure, product roadmap, and dedicated teams. This independence is essential to guarantee neutrality towards external clients.Security and Confidentiality
Several safeguards underpin this independence and ensure data security:- 100% GDPR compliant, ensuring the protection of personal data.
- ISO 27001 certification in progress, reflecting the highest standards in cybersecurity.
- An information barrier separating Flex-O from SaaSOffice and all other clients, guaranteeing the absolute confidentiality of data.
A Broader Market Vision
SaaSOffice now addresses a market that extends well beyond coworking. Thanks to its modular and scalable approach, the solution has already been adopted by other segments of the flexible real estate sector, from property investment funds and hospitality to large corporate headquarters and storage companies. The ambition is clear: to become the software reference for the management of hybrid and innovative spaces.
With a team of 50 employees, SaaSOffice continues to evolve rapidly, integrating new features and adapting to market needs. Every update is shaped by a single objective: to simplify life for operators and enrich the experience of end users.
A Tool Built for the Future of Space Management
SaaSOffice is far more than a software platform, it represents a new way of conceiving and managing flexible workspaces. By transforming a successful internal experience (Flex-O) into a universal solution, Christophe Courtin and Didier Fornetti have paved the way for a new generation of operators capable of scaling rapidly, while remaining profitable and client-centric.
At a time when companies are increasingly seeking flexibility in their office footprint, SaaSOffice positions itself as an indispensable partner for operators ready to take the next step.
Its expansion into other verticals — corporate, hospitality, and storage — confirms its potential to become the reference platform for European proptech.
