Deep use cases vault India to ChatGPT’s top global market: OpenAI’s India MD

Prabhjeet Singh, managing director, OpenAI India
India has become ChatGPT’s largest market globally in terms of weekly active users, with the local user base doubling since January this year, said OpenAI India managing director Prabhjeet Singh.
User growth: “In less than a year, it’s doubling. It just gives you a sense of (how) people are beginning to find relevance and deep use cases,” Singh told ET in his first media interview since joining OpenAI in August.
Payments push: OpenAI is expected to make announcements concerning UPI and payments over the coming weeks.
Enterprise adoption: Singh said the company was “seeing a real shift from early days of pilots and demos — common early this year and late last year — to now scaled adoption and production-scale deployment”.
AI regulation: As concerns mount over the potential misuse of increasingly autonomous AI agents, Singh said the company was actively engaging with government agencies and enterprises to protect critical infrastructure.
Outlook: “I also anticipate much more deeper, from our vantage point, deeper localisation and investments in the ecosystem, whether it be product experience, partnerships, working with the government, or working with the community.”
From bikes to billions: Rapido’s gross order value quadruples in two years to $4 billion

Aravind Sanka, founder, Rapido
Ride-hailing startup Rapido has crossed $4 billion in annualised gross order value (GOV), quadrupling its scale in two years, as it steps up expansion across mobility and food delivery following a $240 million fundraise in May this year, according to people in the know.
By the numbers:
- Daily orders: Around 8.3 million across its services, with ride-hailing accounting for more than 95%.
- Monthly active users: Grew 27% between January and October this year.
- Market presence: Expanded to nearly 500 cities from around 100 a few years ago.
- Market share: Estimated 60% across bikes, auto rickshaws and four-wheeler cabs, according to industry executives.
- Valuation: Raised $240 million in May at a $3 billion valuation.

Food delivery push: Rapido has modelled its food delivery platform Ownly on the zero-commission approach it follows in ride-hailing. Launched in Bengaluru earlier this year, Ownly has since expanded to Hyderabad, Kolkata and New Delhi.

Fireside Ventures cofounder and partner Vinay Singh is exiting the Bengaluru-based venture capital firm after nearly a decade, the company announced on Monday.

Pixxel’s Indian ownership comes under scrutiny

Awais Ahmed and Kshitij Khandelwal, cofounders, Pixxel Space
Bengaluru-based spacetech startup Pixxel Space which develops hyperspectral satellites has defended its Indian ownership and control after its decision to establish a US subsidiary has triggered questions about its corporate structure.
What triggered the debate: Last week Pixxel announced the establishment of Pixxel Federal, a US subsidiary set up to serve US civilian, defence, and intelligence agencies. The new entity will be headed by Allyson Jenkins, who previously led Pixxel’s public-sector business in the US.
GalaxEye’s position: GalaxEye, another Bengaluru-based spacetech startup, said it had consciously chosen to build its business from India despite considering other locations. Without naming Pixxel, the company said all its contracts and bids had been pursued through a single Indian entity.
Pixxel’s clarification: Pixxel founder and chief executive Awais Ahmed pushed back against the suggestion that having multiple entities across countries should raise questions about a company’s Indian credentials. He said separate entities were often necessary in regulated sectors such as space and defence to meet local requirements.
