There's a good hype around climate tech, and some related sectors, like food tech, remain hot despite the downturn,  said Helen Lin, a partner at Silicon Valley-based At One Ventures."When there is an economic downturn, investors typically take a flight to safety. So the more you look ... like a brick of gold to an investor, that is, a stable store of value that is not going to be hugely volatile, the more they will actually flock to you," she said.At One Ventures is backing early-stage disruptive deep tech companies that have the potential to upend the unit economics of established industries while dramatically reducing their footprint on the planet or pioneering industries that are actively regenerative. Since its 2020 launch, the firm has made 28 investments."Carbon is important.
