Twitter Inc.'s former chief financial officer has joined SoftBank Group Corp.-backed Plenty Inc. in the same role as the indoor farming startup prepares for international expansion and improvements to its vertical growing technology.

Mike Gupta helped take Twitter public in 2013 and left for Docker Inc. two years later. Earlier, Gupta was treasurer at gaming company Zynga Inc., helping to lead its initial public offering, and had previously spent about eight years in various roles at Yahoo.

"It's not new for me to be in hypergrowth companies that are entering unchartered territory," Gupta said in an interview. "This is a very capital intensive business, so having someone who can think about how we raise and deploy capital in the long run will be very important."
