Wu said that according to Forbes, Flowcarbon, a climate technology startup co-founded by former WeWork CEO Adam Neumann, is quietly returning investor funds. The company's previously highly anticipated "Goddess Nature Token" (GNT) project has failed. Flowcarbon announced in May 2022 that it had completed a $70 million financing, of which at least $38 million came from token sales. Well-known investment institutions a16z, General Catalyst and Samsung NEXT participated in it. However, GNT has been delayed in its issuance, and the company recently began to refund investors.
