Our values
An online tool with real people behind it
With lots of passion, a great team and the desire to act, we enable every project leader to make their dream come true by helping them fund their project. We are absolutely at your disposal to support you in getting started with our platform and help you thrive in the best conditions.
Details that matter
Spending hours choosing an icon, calling all our clients to see how they're doing, hesitating over the name of a feature so it's clear to everyone: this is part of our team life and company DNA. We strive to be as conscientious as possible to always best serve our mission.
Work in progress
Our solution is designed for real use cases, providing turnkey answers to all your challenges as a project leader. We won't hesitate to reach out to you for inspiration. Even though we've been immersed in the industry for 10+ years, you're the one on the ground. We listen, we adapt, and together, we grow.
Change is constant
We are the first ones concerned and interested in our achievements. Osponso is objectively already amazing, yet our roadmap remains full between our dreams and reality. Always fully committed on the development side, we don't hesitate to redefine our priorities, add features and always aim higher so Osponso becomes your ideal companion.
A passion-driven business
We take real pleasure in advancing our solution to give you ever more satisfaction in managing your partners and allow you to put your energy to good use in your project. Your satisfaction, your growth and your praise remind us why we do this and are our daily motivation.
Amazing collaborations
We are fortunate to work in contact with sectors as stylish as they are diverse, to interact with the best in their field and to work for stakeholders we admire. To you reading these lines, receive our eternal gratitude. Your contact is our success, your success is also our team victory.
Do what we say and say what we do
We have nothing to hide, just identified needs, ideas, and the desire to make them happen. We play it with total transparency with you as well as internally. No labels, no hierarchy, we pay the same attention to the ideas/feedback/comments of every team member, whether they're a founder or an intern.
