Disgraced WeWork founder Adam Neumann is back again with his real-estate project Flow (www.flow.life) and found a prestigious investor. Well-known Venture-capital firm Andreessen Horowitz is investing $350 million at a valuation above $1 billion, WSJ reports, making it one of the largest-ever investments for an early-stage startup. The firm, also known as a16z earlier this year, also backed Flowcarbon, another startup co-founded by Neumann. Flow is still in secretive stealth mode and is scheduled to launch in 2023.
