Business model and strategy
Block
How it makes money
Block runs a two-sided network. On the seller side, Square charges a fee on each card payment (in the U.S. on its free plan, 2.6% plus 15 cents in person and 3.3% plus 30 cents online) and adds paid software, hardware, payroll, banking and Square Loans. On the consumer side, basic Cash App transfers are free;
Growth strategy
Block's 2026 plan has four parts. Square is selling to larger and international sellers through a field sales team and independent sales organization partners; international GPV grew 28% in the second quarter of 2026. Cash App wants to be the main bank account for people with several income sources, using direct deposit and Cash App Green rewards status;
Competitive advantage
Block's advantage is owning both ends of many small transactions. Cash App's peer-to-peer network spreads by itself, since receiving money means downloading the app, and every added product (the Cash App Card, direct deposit, Borrow, Afterpay) raises revenue per customer without new acquisition cost.
TCS
How it makes money
TCS earns revenue through global IT services and consulting, built around eight industry verticals and geographic diversification.
Growth strategy
TCS is growing through AI, cloud modernization, cybersecurity, data, engineering services, platforms, large transformation deals, partnerships and deeper penetration of existing enterprise accounts.
Competitive advantage
TCS' advantage is delivery scale, Tata trust, large-account depth, industry domain expertise, training infrastructure, strong margins and a reputation for mission-critical execution.
