Competing to propose Open Source Collaboration solutions against multi-billion companies is a challenging endeavor. But it's not a technical one. While your users will demoralize you showing you all what you miss compared to your proprietary competitors having deep pockets to fund their R&D, you'll think that Open Source software is just not good enough.

But the real issue is not technical, it's economical and financial. Over the 20 years of XWiki and CryptPad, we have been able to measure what we miss for Open Source to be able to provide end user applications respecting user's Freedom and Privacy.

We have also been able to see how the changes of price of competitors have brought us more customers allowing us to increase the funding of our own software.

The challenge is a financial challenge, a business model challenge. In this talk we will show how we manage to hack our funding throughout the years and find ways to progressively improve our software, gaining status year by year and then allowing to increase customer revenue.

We will also present our belief that in order for Open Source to strive, the community needs to solve the financial challenge and also chip in. We'll present our FOSS Fund, which is our own way to give back to other Open Source projects that we use at XWiki SAS.
