Disruptive Innovation in Finance: A Cross-Vertical Analysis of Technology-Driven Fintech Firms

Abstract

Fintech startups are reshaping financial services through technologies like AI, blockchain, and big data, often outperforming traditional banks in speed, efficiency, and accessibility. This study examines five leading firms—Chime, Stripe, Ramp, Alloy, and Fireblocks—across key verticals such as neobanking, payments, and digital asset security. Using data from public sources and web scraping, we analyze tech adoption patterns with Python-based tools. Findings show widespread use of AI and big data for fraud prevention, onboarding, and identity verification, while blockchain is applied more narrowly in crypto security. These firms show rapid growth, prompting legacy institutions to respond via partnerships and digital innovation. The study highlights how technology is driving disruption and reshaping competition in finance.
