About
Fizz is a San Francisco-based student financial platform — backed by Y Combinator with $14.4 million raised in a Series Seed round in June 2024 from Kleiner Perkins, SV Angel, YC, and founders of eight unicorn companies — providing college students at 300+ US universities with a debit card that builds credit history automatically (reporting to credit bureaus based on spending patterns without requiring debt), a free credit score monitoring dashboard, personalized spending insights, financial education courses, and budgeting tools designed to help young adults build credit and develop financial literacy without the risk of credit card debt. Founded by Carlo Kobe and Scott Smith (Harvard and Cornell dropouts who identified the gap in student financial products), Fizz has evolved from a credit-building debit card to a comprehensive student money app (updated October 2024).

About
Block, Inc. is a San Francisco, California-based financial technology company — publicly traded on the New York Stock Exchange (NYSE: SQ) as an S&P 500 Information Technology component (added to the S&P 500 on July 23, 2025, replacing Hess Corporation) — operating two primary financial platforms: Square (merchant payment processing, point-of-sale hardware, and business banking for small-to-mid-size merchants) and Cash App (peer-to-peer payments, digital banking, stock investing, and Bitcoin transactions for individuals) alongside Afterpay (buy now pay later), Tidal (music streaming), and TBD (decentralized finance), through approximately 12,000 employees. CEO Jack Dorsey (co-founder with Jim McKelvey in 2009 as Square, rebranded to Block in December 2021) leads the company's strategy of building an interconnected ecosystem of financial services that connect individual consumers (Cash App) with merchants (Square) and the broader financial ecosystem. In fiscal year 2024, Block reported gross profit of approximately $8.9 billion, with Cash App generating approximately $5.0 billion in gross profit (+14% year-over-year) driven by Cash App Card, direct deposit adoption, and Cash App Pay, while Square generated approximately $3.7 billion in gross profit (+9%) driven by software and banking products alongside payment processing. Block acquired Afterpay for $29 billion in January 2022 — integrating the Australian buy-now-pay-later platform into both Square (merchant installment offer at checkout) and Cash App (consumer Afterpay integration).
