About us

What's OneRagtime?

Our mission is an ambitious one: contribute to shaping tomorrow’s world through innovation and technology. To do so, we are building something special for entrepreneurs and for investors alike: a venture platform-powered ecosystem made of a venture platform, a studio and advisory services.
We strongly believe that the key to success for our start-ups is to be supported and backed by the right people. This is what the OneRagtime community is about. It’s an ecosystem in which start-ups can bloom and become the next global champions thanks to access to capital, network, knowledge and operational resources.
On the other hand, we offer our investors a prime deal flow carefully scouted and selected by our team, a seamless and fully digitalised investment process, from due diligence to terms negotiations.
In a nutshell, we are bridging the gaps between start-ups, investors and corporates to spark the next wave of global champions.


We are a team of crazy millennials operating under the supervision of experienced senior executives. Founded by Stéphanie Hospital and Jean-Marie Messier, OneRagtime is also guided by our wise Godfather, Philippe Bourguignon, and gathers amazing talents such as our operations guru Josep Solé and our superstar mentor Laurence Bret. What better combination of emerging talents and confirmed achievers to scout and back the new global gamechangers?
