About Me

Sarath Ratanavadi is CEO of Gulf Development, one of Thailand's largest conglomerates with interests in telecommunications and digital infrastructure. Gulf Development was established in 2025 following a merger between power producer Gulf Energy Development and telecom giant InTouch Holdings, the biggest shareholder of Advanced Info Service (AIS). In 2024, Gulf Energy's joint venture with Binance launched a crypto exchange in Thailand. Gulf bought a stake in Kasikornbank in May 2025 and continued to raise its shares to become the second largest shareholder of Thailand's third largest bank by assets. Gulf's joint venture with Singtel and AIS to set up data centers in Thailand is expected to start operations in 2025.
