Carta, Inc. vs PhonePe: Strategic Comparison

This in-depth comparison examines Carta, Inc. and PhonePe across revenue, market value, business model, competitive positioning, and long-term growth strategy. Whether you are researching Carta, Inc. on its own, evaluating PhonePe, or weighing the two companies side by side, the breakdown below highlights where each company leads and where the gap between Carta, Inc. and PhonePe is widest.

On the headline numbers, annual revenue is $442.0M (unaudited) (FY2024) for Carta, Inc. and ~$918.7M (FY2026) for PhonePe, while their respective market capitalizations stand at N/A and N/A. Carta, Inc. is headquartered in United States and PhonePe in India, and those different home markets shape how each company competes.

Carta, Inc.: Carta is the system of record for who owns what in private companies and funds. Founders use it to issue options and model funding rounds, employees use it to see and exercise their equity, and VC, PE, and private credit managers use it to run fund accounting and LP reporting. That position between companies and investors is what lets Carta sell valuations, fund administration, and legal services. The company is headquartered in San Francisco, California.

PhonePe: PhonePe is the largest app on India's Unified Payments Interface, handling more than 45% of UPI volume. Users send money between bank accounts, scan merchant QR codes, pay bills, and buy insurance, loans and investments in one app. The company is based in Bengaluru and controlled by Walmart. It became a separate company from Flipkart in 2022 and filed for an Indian IPO in 2025. The company is headquartered in Bangalore, India. PhonePe was founded in December 2015 in Bengaluru, Karnataka, India, by former Flipkart executives Sameer Nigam, Rahul Chari, and Burzin Engineer to pioneer payments on India's Unified Payments Interface (UPI), growing into India's dominant digital payments and fintech platform backed by Walmart.

Carta, Inc. and PhonePe pursue distinct approaches to generating revenue, and understanding how each company operates is the foundation of any fair comparison between Carta, Inc. and PhonePe.

Carta, Inc. business model: Carta sells annual software subscriptions plus service fees on both sides of the private market. Companies pay for cap table management, equity plan administration, and 409A valuations, with prices rising as stakeholder counts and funding stages grow. Investment firms pay for Fund ERP products: fund administration (software plus dedicated fund accountants), fund tax and K-1s, portfolio valuations, CRM, forecasting, and loan operations for private credit. Since May 2026, Carta Law adds outcome-based legal and compliance work such as NDAs, KYC, investor onboarding, and LP transfers. Sacra estimates that in 2023 cap tables and 409A valuations made up about 67% of ARR, fund administration about 27%, and private equity products about 5%. Carta shut its secondary trading business in January 2024, so brokerage is no longer part of the model.

PhonePe business model: Consumer UPI payments on PhonePe are free, and person-to-merchant UPI has carried zero merchant discount rate (MDR), so the payments app mostly works as a way to bring in users. Revenue comes from four main areas. First, merchant payments: SmartSpeaker soundbox and POS device rentals, payment gateway fees and card-based transactions. These made up about 28% of revenue in FY25 and about 31% in the six months to September 2025. Second, consumer payments such as bill payments, recharges and incentives, including government UPI incentives (PIDF). Third, distribution of loans and insurance from partner lenders and insurers, which grew from about 1% of revenue in FY23 to about 7.8% in FY25 and 11.6% in H1 FY26. Fourth, newer businesses such as the Share.Market broking app, mutual funds, the Indus Appstore and Pincode. An MDR framework for UPI being discussed in 2026 could open a new revenue stream.

The durability of a company's moat often decides long-term winners. Here is how the competitive advantages of Carta, Inc. stack up against those of PhonePe.

Carta, Inc. competitive advantage: Carta's main advantage is its two-sided network. Startups put investors on their Carta cap tables, investors adopt Carta for fund administration, and those funds steer portfolio companies to Carta. As a registered transfer agent holding the legal record of ownership, Carta is also costly to leave: switching means migrating years of grants, vesting schedules, and investor records. Its cap table data feeds 409A valuations, compensation benchmarks, and portfolio valuations for funds.

PhonePe competitive advantage: PhonePe's lead comes from scale on both sides of the UPI network. It has more than 700 million registered consumers and 50 million registered merchants. Much of that merchant base was built by field sales teams placing QR codes and SmartSpeaker devices across nearly every Indian pin code. That reach lets PhonePe sell loans, insurance and investments to customers it already has, without paying much to acquire them. Its UPI share has stayed above 45% even as Google Pay, Paytm and newer apps compete.

Future prospects matter as much as current results. The growth strategies below explain how Carta, Inc. and PhonePe each plan to expand from here.

Carta, Inc. growth strategy: Carta grows by selling more products to the firms already on its ledger. The playbook is to take a professional service (409A valuations, fund accounting, legal work), automate it, and tie the output to Carta's system of record. Fund ERP bundles fund administration, fund tax, portfolio valuations, data collection, forecasting, and CRM. Acquisitions fill gaps: Tactyc (fund forecasting), Sirvatus (private credit loan operations, October 2025), Accelex (AI data extraction, October 2025), ListAlpha (CRM), and Avantia (legal and compliance, May 2026).

PhonePe growth strategy: PhonePe's growth plan is to earn more from the users it already has rather than add payments users. It is focusing on four areas. Credit distribution covers personal, merchant and secured loans through partner lenders. Insurance broking is a second area. Wealth covers mutual funds and Share.Market broking. Merchant services cover soundboxes, POS devices and the payment gateway. Alongside these, it runs consumer bets such as the Indus Appstore, which challenges Google Play in India, and the ONDC-based Pincode app. In 2026 it also cut costs, including closing its US engineering office in September.

A closer look at the financial trajectory of Carta, Inc. and PhonePe rounds out the comparison.

Carta, Inc.: Carta does not publish audited financials. Henry Ward has said the company was approaching $500 million in annual recurring revenue in 2025. Sacra estimates revenue of about $373 million in 2023, $442 million in 2024 (+19%), and $515 million in 2025 (+16.5%), with growth slowing after the end of zero-rate venture funding. Carta raised its last primary round, a $500 million Series G led by Silver Lake and Lightspeed, at a $7.4 billion valuation in August 2021; a January 2022 employee secondary sale reportedly priced it at $8.5 billion. Total equity funding is roughly $1 billion.

PhonePe: PhonePe's revenue from operations grew from ~$338 million (₹2,914 crore) in FY23 to ~$587 million (₹5,064 crore) in FY24 and ~$825 million (₹7,115 crore) in FY25, a CAGR of about 56% according to its DRHP. Over the same period, its loss margin improved from about -91% to -23%. FY25 net loss was ~$200 million (₹1,727 crore), and the company reported positive free cash flow that year. Growth then slowed. FY26 revenue rose 11% to about $919 million (₹7,920 crore), and consolidated net loss widened 62% to ~$324 million (₹2,792 crore), according to MCA filings reported by Moneycontrol. ESOP charges tied to the IPO and losses at subsidiaries drove much of the wider loss, and PhonePe put its normalised FY26 loss at about $160 million (₹1,377 crore). PhonePe is India's absolute dominant digital payments and financial services platform, commanding a massive private market valuation of approximately $12 billion.
