150 TL;DR: Deepinder Goyal is moving beyond Eternal with Temple, a premium metabolic-tracking wearable, and LAT Aerospace, an eight-seat regional aircraft venture. The opportunity is large, but both bets hinge on independent scientific validation, certification and infrastructure rather than founder reputation. Article: Deepinder Goyal is preparing two high-risk bets beyond Eternal: Temple, a roughly $1,000 wearable he says can track metabolic state in real time, and LAT Aerospace, which is developing an autonomous eight-seat hybrid-electric short take-off and landing aircraft. Temple could launch within six to 12 months, while Goyal has personally committed $20 million to LAT. The projects now define his post-CEO agenda. Eternal lists Goyal as vice-chairman and non-executive director, leaving him room to pursue ventures with far longer development cycles and materially higher technical risk than consumer delivery. Temple says its temple-mounted sensor reads “Entropy”, a measure of metabolic and sympathetic demand, through the superficial temporal artery. Goyal told Bloomberg the company would launch it “as a wellness device with peer-reviewed studies and everything”, but the reported science has not yet been independently validated. That distinction matters in a fast-growing market. An India Brand Equity Foundation review, citing industry estimates, projects India’s wearable medical-device market to rise from ₹9,256 crore in 2024 to ₹37,380 crore by 2033, a 15.5% annual growth rate; it adds that “real growth lies further ahead, where these devices are validated medically”. LAT addresses a different bottleneck: regional mobility. Its official plan combines short-field aircraft, indigenous propulsion and autonomous systems; India counted 165 operational airports and 677 UDAN routes by mid-2026, evidence of demand but also of the infrastructure and regulatory coordination required. Temple must now prove repeatable accuracy, peer-reviewed evidence and responsible health-data handling. LAT must convert prototypes into certified aircraft and viable routes. Reputation opens doors; validation, safety and economics decide whether either venture scales.
