As the goal is developing the platform as an open-source project, I think it could be interesting to imagine the software not only as a solution for couchers, but for a general application. The model for this approach would be Wikimedia, having developed MediaWiki to be used for Wikipedia, but offering the software for anyone to use as a wiki platform.
I could see a software bringing together hosts & guests being useful outside of the global travel community. Let’s say universities that want to offer new students the possibility to stay with other students for their first week/month. Or political parties/associations that hold a member meeting and would have local members interested in hosting visiting ones. Or the christian churches, they propagate homestaying for international church events.
Providers from the sharing economy target similar groups by offering “for events”-functionality (e.g. https://homestay.com/events or https://news.airbnb.com/introducing-a-new-way-event-organizers-can-offer-attendees-more-accommodation-choices/ ) Other hospex platforms already have their codebase open-source, but not taylored towards general application.
Some advantages I could see:
- attract a broader range of stakeholders and feedback
- more engagement with the codebase, especially if institutions and not only individuals see the solution as valuable
- make genuine hospitality sharing more widely known and recognized
- diversify opportunities to attract donations and grants
