On the headline numbers, American Express Company reports annual revenue of $72.2B against $5.1B for Twilio Inc., while their respective market capitalizations stand at $205.8B and $37.8B. Both American Express Company and Twilio Inc. are headquartered in United States, so they compete in a shared home market and regulatory environment.

American Express Company: American Express is a payments company that sells access to its own card members. It does not rent its network to thousands of issuing banks the way Visa and Mastercard do; it issues the cards, signs the merchants and keeps the discount fee. In FY2025 it carried $1,897.0 billion of network volumes, had 152.8 million cards in force worldwide including 86.6 million it issues itself, and reported $72.2 billion in total revenues net of interest expense. The premium lineup runs from the Green Card up through the Gold Card at $325 a year, the Platinum Card at $895 after its September 2025 refresh, and the invitation-only Centurion Card, whose fee the company does not publish.

Twilio Inc.: Twilio reported FY2025 revenue of $5.067 billion and net income of $33.8 million, then grew Q2 2026 revenue 22% to $1.50 billion. Khozema Shipchandler is CEO, and the company had 5,492 employees as of June 30, 2026.

American Express Company and Twilio Inc. pursue distinct approaches to generating revenue, and understanding how each company operates is the foundation of any fair comparison between American Express Company and Twilio Inc..

American Express Company business model: American Express runs a closed-loop payments business: it issues the card, owns the network, underwrites the credit and contracts with the merchant. Visa and Mastercard only move the transaction between an issuing bank and an acquiring bank, so they never see both sides of a purchase. Because Amex holds every side of the relationship, it keeps the whole merchant discount fee rather than sharing it, and in FY2025 discount revenue equalled 2.24 percent of the $1,669.8 billion its card members billed. The trade-off is price: merchants pay more to accept Amex than to accept an open-loop card, so the company has to justify the rate with card members who spend more. Average spending per proprietary basic card member was $25,453 in 2025. Amex funds that proposition with annual fees, which reached $10.0 billion in net card fees in FY2025 at an average of $117 per proprietary card, and spends the money back on Membership Rewards, the Centurion Lounge network, Resy and Tock dining access and service. Since converting to a bank holding company in 2008 it has also lent against card balances through American Express National Bank, producing $17.4 billion of net interest income in FY2025.

Twilio Inc. business model: Twilio makes most of its money from usage-based fees: customers pay per message, per voice minute, per email, or per verification sent through its APIs, so revenue rises with their traffic. Messaging alone generated $2.878 billion of FY2025 revenue. On top of that usage base, Twilio sells subscriptions and committed-spend contracts for Segment (customer data), Flex (contact center), and newer AI and identity products. Carrier pass-through fees, such as U.S. A2P 10DLC surcharges, are billed to customers and inflate reported revenue, which is why Twilio also reports organic growth that excludes incremental carrier fees.

The durability of a company's moat often decides long-term winners. Here is how the competitive advantages of American Express Company stack up against those of Twilio Inc..

American Express Company competitive advantage: American Express competes on the spending power of its card members rather than on price or ubiquity. Average spending per proprietary basic card member was $25,453 in 2025, which is the argument it makes to merchants who pay a higher discount rate, an average of 2.24 percent of billed business. Owning both sides of the transaction also gives it card member and merchant data that open-loop networks do not hold, which feeds underwriting and targeted offers. Credit outcomes reflect the customer mix: a 2.0 percent net write-off rate on consumer and small business loans and receivables in 2025, with 1.3 percent of balances 30 or more days past due.

Twilio Inc. competitive advantage: Twilio's advantage comes from developer mindshare, API breadth, carrier relationships, global routing, customer integrations, data products, and mission-critical communications workflows.

Future prospects matter as much as current results. The growth strategies below explain how American Express Company and Twilio Inc. each plan to expand from here.

American Express Company growth strategy: Amex's growth strategy is aggressively focused on capturing the next generation of wealthy spenders: Millennials and Gen Z. They have successfully revamped their well-known Platinum and Gold cards with perks tailored specifically for younger demographics (like Uber credits and dining rewards), resulting in rapid growth among younger cohorts. Additionally, they are heavily targeting small and medium-sized businesses (SMBs), aggressively expanding their corporate card and B2B payment processing services to capture large commercial spending volumes.

Twilio Inc. growth strategy: Twilio is positioning itself as communications and identity infrastructure for AI agents. Its plan combines usage growth in messaging and voice, cross-selling Segment customer data, Flex, and Verify to existing accounts, adding agent identity through the November 2025 Stytch acquisition, and keeping operating costs in check while returning cash through buybacks.

A closer look at the financial trajectory of American Express Company and Twilio Inc. rounds out the comparison.

American Express Company: American Express reported $72.2 billion in total revenues net of interest expense for FY2025, up 10 percent, and $10.8 billion of net income, or $15.38 per diluted share. The mix is less fee-only than its premium image suggests: discount revenue on merchant transactions was $37.4 billion, net interest income on card member loans was $17.4 billion, net card fees were $10.0 billion and service fees and other revenue were $7.5 billion. Growth in 2025 came disproportionately from the two smaller lines, with net card fees up 18 percent and net interest income up 12 percent against 6 percent growth in discount revenue. Return on average equity was 33.9 percent, the net write-off rate on consumer and small business loans and receivables was 2.0 percent, and the company declared $3.28 per share in dividends while average diluted shares fell from 713 million to 696 million.

Twilio Inc.: Twilio moved from heavy losses to profit in three years. Net loss attributable to common stockholders was $1.256 billion in 2022 and $1.015 billion in 2023, narrowed to $109.4 million in 2024, and turned into net income of $33.8 million in 2025 on revenue of $5.067 billion. In Q2 2026 Twilio reported revenue of $1.499 billion, GAAP income from operations of $84.5 million, non-GAAP income from operations of $284.6 million, and record free cash flow of $352.6 million. Q2 2026 GAAP net income of $1.067 billion was inflated by a one-time, non-cash release of a valuation allowance on U.S. deferred tax assets worth $5.91 per diluted share. Dollar-based net expansion improved to 116% from 108% a year earlier. A $2.0 billion buyback authorized in January 2025 continues the capital-return program that followed a $3.0 billion repurchase plan.
