Hi, Actually my plan didn't even rely on donation to sustain the project and reach a global scale. you can learn more about the master plan here: https://www.kerkour.fr/blog/bloom-a-free-and-open-source-goo...
1. Build free software and charge for hosting, security of hosted data and enterprise support
2. With this money reduce prices, free the data and the access to scientific knowledge
3. With this money and this community create the open infrastructure to run these software and host this open data
Donation are just a plus, and because I didn't had time to implement payments before launching :) (it's the first day I talk publicly about the project, so I think it's understandable that donation metrics are not so great).
Regarding how much work have been done until today, it's been 6 months I eat pastes :)
