Built for India's pharma and IT capital

Hyderabad pairs one of India's largest IT and SaaS bases, in HITEC City, Gachibowli and Madhapur, with the country's biggest pharmaceutical and life-sciences cluster around Genome Valley. A thriving startup ecosystem anchored by T-Hub sits alongside deep strength in banking, healthcare and retail.

Each of these runs on timely messaging. OTP logins and 2FA for software and fintech teams, batch and supply-chain alerts for pharma, and appointment, transaction and campaign messages for everyone else, all have to land in seconds.
