Human expertise & field know-how
Off Markette was born from the meeting of two complementary worlds: the human, on-the-ground expertise of Vincent Marette, a real-estate advisor for more than fifteen years, and the digital vision of Sébastien Ollagnon, a real-estate web specialist since 2013.
From this alliance emerged a shared conviction: the real estate of tomorrow will be more discreet, more qualitative, more collaborative — and augmented by artificial intelligence.
Before being a real-estate advisor, Vincent Marette is a man of trust. His sincerity, integrity and kindness are the foundation of every relationship he builds. He never seeks to sell at any cost: he supports, advises and defends his clients' interests above all.
For Vincent, real estate is not a succession of transactions. Behind every project lies a life story, a family, a change of direction, an inheritance or a fresh start. It is this deeply human dimension that guides each of his decisions and lets him build lasting relationships based on listening, transparency and respect.
Over more than fifteen years of experience and thousands of encounters, this approach has allowed him to build an exceptional network. Around him gravitates a community of owners, qualified buyers, investors, notaries, partners, craftsmen, real-estate professionals and even advisors from competing networks. Because Vincent always favours human relationships over competition, he maintains trusted ties with professionals of every background: SAFTI, iad, independents, traditional agencies and prestige real-estate specialists.
It is precisely from this philosophy that OFF MARKETTE was born.
Co-founder of Off Markette · Real-estate web & AI
Sébastien Ollagnon has worked in real-estate web since 2013. Passionate about technology as much as human relationships, he has made digital innovation the common thread of his career.
A founding member and co-creator of a property-management platform dedicated to rental management for judicial officers (bailiffs), he learned to design reliable, rigorous tools built for demanding professionals.
Today, Sébastien is spreading his own wings and co-founding Off Markette alongside Vincent Marette. Together, they are imagining a new-generation real-estate platform where artificial intelligence amplifies human know-how rather than replacing it.
The digital vision of Off Markette
OFF MARKETTE, a relational ecosystem.
Off Markette is not simply a platform of confidential listings. It is a relational ecosystem where opportunities circulate through trust, recommendation and a solid human network. Many properties thus find their buyer even before being publicly listed, with the utmost discretion and remarkable efficiency.
Thanks to this collective strength, Vincent can quickly connect the right seller with the right buyer, often before the traditional market is even aware of the opportunity. This approach lets his sellers preserve their confidentiality while enjoying targeted visibility among genuinely qualified buyers.
Highly adaptable, Vincent knows how to understand everyone's expectations, motivations and sometimes even concerns. He takes the time to listen, advise and build a tailor-made strategy, without ever imposing a pace or a decision. Every project benefits from personalised support where people always remain at the centre.
With Off Markette, Vincent Marette shows that there is another way of doing real estate:
Here, the value of a network matters as much as that of a property, and trust remains the finest investment.
