Today, millions of first-timers start a SIP on their phone in minutes. The company that did the most to make that normal is Groww. Here is the story, with the numbers behind it.

01. The journey in five milestones

2016Founded by Lalit Keshre, Harsh Jain, Neeraj Singh and Ishan Bansal
2017Launches as a direct mutual fund platform
2020Adds stock broking
Sept 2023Overtakes Zerodha in active clients
Nov 2025Lists on the stock exchanges

02. The playbook: how it won

  1. Start where beginners startGroww began with direct mutual funds and SIPs, the easiest way into investing. By the time it offered stock trading in 2020, it already had a base of users who trusted the app.

  2. Make it feel simpleA clean interface, plain-language explanations and fast onboarding. Rivals built for active traders; Groww built for someone opening a first demat account.

  3. Keep widening the appStocks, F&O, IPOs, ETFs and more under one roof. A user who came for a SIP could later trade without switching apps.

  4. Go direct, stay leanNuvama points out that all of Groww’s clients come directly, whereas Angel One also acquires clients through sub-brokers and pays them commission. Nuvama also describes Groww as one of the lowest-fee players in the industry.

  5. Ride the waveRetail participation exploded, and Groww captured far more than its share of the newcomers.

03. The overtaking of Zerodha

Zerodha pioneered discount broking and held the top spot for years. Then, in September 2023, Business Standard reported that Groww had 6.63 million active clients against Zerodha’s 6.48 million, ending Zerodha’s long run at the top. Groww’s share of the NSE’s active clients was about 19.9%, versus 19.4% for Zerodha. The gap has widened every year since.

06. Winning in a shrinking market

Growth has not been a one-way street. Active clients across the industry fell by 34.88 lakh to 4.57 crore in FY26, from 4.92 crore in FY25. Zerodha lost 9.95 lakh clients that year and Angel One lost 8.15 lakh. Groww, meanwhile, grew its share. When the market cooled, its lead got bigger, not smaller.

07. Going public

Groww listed in November 2025. Its shares jumped about 30% on debut, valuing it at roughly $8.9 billion. The company was also profitable, reporting a net profit of ₹1,824 crore on revenue of ₹3,902 crore in FY25.

Reality check: “No. 1” means by active clients.
That measures reach, not profit. Zerodha, for example, reported a net profit of ₹2,907 crore on revenue of ₹6,875 crore in FY23 on a far smaller client base, and remains famously profitable. Outlook Business makes the same point: active clients reflect reach, not profitability.

08. Strengths and risks

✅ What works

Beginner-friendly product · direct client acquisition · broad product range · a lead that grew even in a down year · profitability at scale

⚠️ What to watch

Heavy reliance on trading income, including F&O, which regulators have been cooling · Angel One’s recent client gains · converting users into lending, asset management and insurance customers

09.The takeaway

Groww did not win by out-trading the traders. It made investing feel easy for people who had never done it, then kept those users inside one app as their needs grew. The next test is whether it can turn the largest customer base in Indian broking into a broader financial-services business.
