Founding Story
Sameer Nigam was born in 1978. He grew up in Delhi and Noida. His dad was an IIT graduate and navy officer. His mom worked at TCS and later earned a PhD. She also became an IAS officer at age 40. Sameer went to Delhi Public School in Noida. He earned a computer engineering degree in Mumbai. He got a master’s in computer engineering from the University of Arizona. He later completed an MBA in entrepreneurship at Wharton. He started his career in 2001 at Shopzilla. He led search product development until 2007. In 2009 he founded Mime360, a digital media platform. Flipkart bought Mime360 in 2011. The sale led him to senior roles at Flipkart. In 2015 he co‑founded PhonePe with Rahul Chari and Burzin Engineer. The goal was to make digital payments easy for every Indian.
First Product and Early Customers
PhonePe launched on August 28, 2016. It used India’s UPI system. The app focused on “digital plumbing” instead of a wallet. Early users joined quickly. The app added about 5,000 new users each day at first. By December 2016 it had 10 million installed users. The early customers were everyday shoppers and small merchants. PhonePe spent heavily on infrastructure before launch. It wanted to be ready for rapid growth.
Early Struggles
Bankers were unsure about partnering on UPI. Investors did not understand the UPI‑first strategy. PhonePe had to explain why it did not build a wallet first. In 2018 ICICI Bank shut PhonePe’s services. The team escalated the issue to NPCI and regulators. Service was restored after the escalation. The company also faced a trademark dispute with BharatPe over the “Pe” suffix. The dispute settled out of court in 2024. Technical UPI outages also tested the team. Each challenge forced the team to improve systems and communication.
Key Turning Points
The UPI launch on August 28, 2016 was a turning point. It gave PhonePe a national platform. The rapid user growth proved the model. In 2022 PhonePe separated from Flipkart. It moved its domicile to India. The company then prepared for an IPO. In July 2024 Sameer Nigam apologized after a backlash over a Karnataka bill. The apology helped calm public sentiment. In 2024 the trademark dispute ended, clearing brand confusion. Each event moved PhonePe closer to a stable, large‑scale business.
Growth with Real Numbers
PhonePe processes over 11.5 billion transactions each month. It has 700 million registered users as of April 2026. FY26 revenue reached Rs 7,920 crore. That is up from Rs 7,115 crore in FY25. The company raised $2.85 billion in funding. It acquired WealthDesk and Indus Appstore to add lending, insurance and wealth services. The “flywheel” model uses payment scale to sell these new products. The ecosystem now includes lending, insurance and wealth management. PhonePe’s monthly transaction volume grew from millions in 2016 to billions in 2026.
Funding, IPO and Acquisitions
PhonePe raised $2.85 billion from investors. After Walmart bought Flipkart in 2018, PhonePe stayed under the Flipkart umbrella. In 2022 it spun out as an independent company. The firm filed draft IPO papers in September 2025. It targeted a $15 billion valuation. SEBI approved the IPO in January 2026. Market volatility caused the listing to be postponed several times. The company continues to prepare for a public listing. Acquisitions like WealthDesk and Indus Appstore expanded its product range and user base.
Outlook
Sameer Nigam still leads PhonePe as CEO. He plays volleyball and owns the Mumbai Meteors team. He gave a $1 million grant to the Sardar Patel Institute of Technology in December 2024. He says the company wants to help every Indian with digital finance. PhonePe aims to keep growing its transaction volume. It also plans to launch more financial products. The journey shows how a focus on national infrastructure can create massive scale.
