You answered before that crowdfunding doesn’t work for BLV. Have you thought about crowdinvesting ?
I don´t know how the crowdfunding campaign has worked, but I think more or less the people could only donate for the campaign, without getting something back.
With a campaign on a crowdinvesting platform everybody how belief in the product could invest even with a small amount of money and have the opportunity to get more money back if BLV came to market.
Maybe have a look at crowdcube or seedrs – the biggest crowdinvesting platforms in Europe.
Or at companisto or conda – germen alternatives.
