The team

It is first and foremost a human adventure between a fine marketing & sales strategist, an inventive technologist and a 3D serial entrepreneur.

They shared a common understanding and vision to bring StartBuilding® to life and a paradigm shift to empower the Construction industry to truly embrace the digital age.


Alexis developed its weapons in the field and very quickly established itself as a leader in the sale of 3D solutions for the building industry.

His career has taken him to various publishers and to the most prestigious clients in the market, with whom he has acquired an excellent reputation. Today, he puts his talent and his aura at the service of Thirtyseven to once again bring the best solution to the world of Construction.

A fine balance between rationality, intuition and fine strategies; here is Alexi’s recipe for overcoming any challenge with brio. Without forgetting a touch of daily humour that his interlocutors can no longer do without.



Robert is now a recognized player in the Construction industry.

Involved since the beginning of his professional career with various software editors, he has accompanied thousands of stakeholders in the construction industry in their digital transition.

He’s addicted to new technologies and social networks, in a good way! He doesn’t just consume them, he masters them. His speciality: generalist! A versatile, inventive and creative technologist, Robert offers offbeat approaches and knows how to find inspiration at any speed.



A true visionary and pioneer of 3D digital models in the AEC (Architecture, Engineering, Construction) sector!

His international career as an entrepreneur, his experience in the creation of fast-growing startups and his knowledge of the world of venture capital are major assets in the structuring and development of Thirtyseven.
