Managing and Scaling a Coworking Operator: Lessons from Flex-O’s Journey to SaaSOffice

When Christophe Courtin founded Flex-O, an eco-friendly flexible office provider, in 2020—in the midst of the COVID crisis—he quickly identified a major gap in the industry: there was no tool available to manage the entire value chain of a coworking operator, from lead generation to accounting, including sales, billing, space management, service offerings, and KPI tracking.

He turned to Didier Fornetti, CTO of Santiane (another company founded by Christophe), to help him design a comprehensive management tool. This tool enabled Flex-O to grow rapidly, remain independent, and become profitable.

Four years later, Flex-O has established itself as:

• 17 locations in major cities
• 60,000 m² of managed space
• More than 2,000 customers
• An independent and highly profitable operator

After four years of R&D, testing, and daily optimization in partnership with one of France’s most dynamic coworking operators—and with the arrival of Brice Arnavon— SaaSOffice was born: an all-in-one software platform designed to revolutionize the management of coworking spaces and flexible offices. This solution led to the creation of an independent company in early 2024.

The Birth of SaaSOffice

Flex-O’s success wasn’t built solely on the creation of attractive and eco-friendly workspaces. It was made possible by a deep understanding of technology. From the very beginning, 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 effectively manage every aspect of the business.

Together with Didier Fornetti, they decided to develop a solution that didn’t yet exist on the market: an all-in-one, modular platform designed specifically for space operators. After proving its value internally at Flex-O, the solution was spun off into an independent company.

That is how SaaSOffice came to be, with a clear goal: to provide operators with a single, secure, and fully integrated platform that allows them to scale with confidence.

Julien Fritz, former Head of Operations at Flex-O — “ As soon as the software was launched, we immediately noticed a real change in our organization. The operational management of our spaces has become much more streamlined thanks to the centralization of information and the automation of many tasks. Having unified data has allowed us to eliminate the use of multiple tools and avoid duplicate data entry, which has resulted in significant time savings, increased efficiency, and reduced costs. It has also enabled us to better track our performance metrics, more easily identify upselling opportunities, and optimize the occupancy rate of our spaces. Very quickly, our teams were able to focus more on customer relationships, which had a direct impact on satisfaction and retention.”

How SaaSOffice Is Redefining Software Solutions for Coworking

All-in-one coworking software

The coworking and flexible office market is booming. But this growth comes with a challenge: the complexity of management. Most operators are still juggling multiple tools—CRM, billing software, access control systems, marketing platforms—that communicate poorly with one another, if at all. This fragmentation slows down decision-making, leads to errors, and drives up costs.

SaaSOffice is a game-changer. Its strength lies in its ability to provide end-to-end management of the entire value chain:

• Lead Generation: Tracking incoming leads, scoring, qualification, and automated nurturing.
• Sales: a clear sales pipeline, quote generation, and integration of the closing cycle.
• Contracts: Integrated generation and electronic signature, management of amendments and renewals.
• Spaces and Options: Granular management of private offices, coworking spaces, meeting rooms, and additional services (parking, concierge services, catering, etc.).
• Billing and Payments: Real-time tracking, automatic invoice generation, seamless accounting integration.

An Optimized Customer Experience

On the customer side, SaaSOffice offers an intuitive application that centralizes all aspects of the relationship: contracts, room reservations, adding options, invoices, and communication with the operator. Coworkers take control of their own experience, with a level of flexibility never before seen on the market.

It is this dual promise—a powerful back office and a seamless customer experience—that positions SaaSOffice as the next-generation software for operators of flexible workspaces.

SaaSOffice: A Strategic Decision-Making Tool

Data-Driven Strategic Decisions

Every day, a coworking operator faces a constant stream of small decisions: Should they adjust the price of a private office? Invest in a new marketing campaign? Extend a lease or reassign a vacant space?

Traditionally, these decisions were based on Excel spreadsheets painstakingly compiled from disparate data sources. With SaaSOffice, all this information is centralized and available in real time.

Each department can access its key indicators immediately:

• CEO: Quickly identify which centers are underperforming and understand why (location, pricing, services, competition).
• CFO: Know the exact cost per acquisition by marketing channel to allocate the budget wisely.
• COO: Optimize occupancy rates, anticipate peaks in demand, and adjust pricing per square meter.
• CCO: Analyze which services generate the most recurring revenue (parking, meeting rooms, food service) 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 the performance of the sales teams and verify that the pipeline is in line with quarterly goals.

From Operations to Strategy

By centralizing this data, SaaSOffice does more than just simplify management: it becomes a a valuable tool for strategic decision-making. Leaders gain both responsiveness and confidence—two essential qualities in a market where speed of execution is paramount.

This operational intelligence also enables better planning: expansion into new cities, the launch of new services, or more informed real estate decisions.

SaaSOffice: A Company in Its Own Right

Independent Governance

Although SaaSOffice was founded as part of Flex-O, it quickly established its independence. Today, the company operates as a separate entity, with its own governance structure, product roadmap, and dedicated teams. This independence is essential to ensuring neutrality toward external customers.

Security and Privacy

Several safeguards reinforce this independence and ensure data security:

• 100% compliant with the GDPR, ensuring the protection of personal data.
• ISO 27001 certification is currently in progress, reflecting the highest standards in cybersecurity.
• A firewall separating Flex-O from SaaSOffice and all other clients, ensuring absolute data confidentiality.

A Broader Market Perspective

SaaSOffice now targets a market that extends far beyond coworking. Thanks to its modular and scalable approach, the solution has already been adopted by other segments of the flexible real estate market: real estate investment funds, the hospitality industry, large corporate headquarters, and storage companies. The goal is clear: to become the leading software solution for managing 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 guided by a single goal: to make life easier for operators and enhance the end-user experience.

A tool designed for the future of space management

SaaSOffice is much more than a software platform: it embodies a new way of designing and managing flexible workspaces. By transforming a successful internal initiative (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 customer-focused.

At a time when companies are seeking ever-greater flexibility in their real estate portfolios, SaaSOffice is positioning itself as an essential partner for operators ready to take the next step.

Its expansion into other sectors—corporate, hospitality, and warehousing—confirms its potential to become the leading European proptech platform.
