Flower Turbines is a serial equity crowdfunding raiser, with rounds closing in December 2019 ($7.5m valuation) and December 2020 ($26m valuation). The company has earned $105,747 in revenue to date (ending 6/30/2020), and believes it will take at least $5m to fund the next 12 months' business operations. It's hard to see the justification for the dramatic increase in valuation. (1/10/2021)
