I found about Faba today and I like that team is very experience and from Europe.I see that you have few good partners already and are oriented towards sustainable energy, ecology, young startups that look to improve something in this world.
Can you tell me how much do I need to invest to be able to promote a company?
You can promote FABA by joining bounty campaign that is going on at the moment.
