US-based AI startup Legitt's Indian-origin Founder Harshdeep Rapal questioned why Kunal Shah was leaving IPO-bound CRED to work as WhatsApp's global CEO. "On second thought, what would make a founder- running a...startup that he has put blood and sweat to build, leave...for Meta?" Rapal said. "It's a different challenge," a user said, with another adding, "It may be a 'tech-itch'."
