Entering the Fintech 2.0 Era
The Fintech industry is going through a foundational shift, driven by AI at its core. What was once a promising experiment has now become mainstream. As early as 2020, more than four out of five financial firms worldwide (85%) were already using AI in some form. Five years later, its role has only deepened. AI now powers almost every aspect of the Fintech landscape, from data analytics and risk management to marketing and customer support. This is the essence of Fintech 2.0: an era where AI is no longer an optional add-on but an indispensable necessity.
The scale of this opportunity is massive. The global Fintech-as-a-Service (FaaS) market is projected to nearly triple within the next five years, growing from about $380 billion in 2024 to over $900 billion by 2029. This hyper-fast growth is not incidental; it is being driven by AI adoption across all facets of the industry’s operations. Staying ahead in this AI-driven wave is critical for competing in global markets, and that starts in the U.S., where fintech adoption is already widespread. With 84% of small and medium-sized enterprises (SMEs) using at least one fintech service, and nearly 9 in 10 U.S. consumers relying on digital platforms to manage their finances, adoption is now mainstream across both businesses and individual users.
From Digitization to Intelligence
The ripple effects of the COVID-19 pandemic accelerated the first wave of digitization, through online banking and mobile payments. The early digital adoption set the stage for a more ambitious, AI-powered transformation. Today, this new wave of Fintech revolution builds on the foundations of Fintech 1.0, but pushes far beyond it, making financial products and services smarter, faster, and more personalized. To see just how far the industry has come, the table below contrasts the traditional approaches in Fintech with the AI-driven practices of Fintech 2.0 in various areas of operation:
Aspect
Pre-AI
Fintech 2.0
Credit Decisions
Underwriting was largely manual or rule-based, using limited data such as salary slips and collateral records. Loan approvals take several days to weeks, and the rigid datasets exclude large segments of the population without extensive credit histories.
AI-driven models analyze thousands of data points for instant credit scoring with improved risk accuracy. The models often utilize alternate data sources such as utility bill payments, e-commerce transactions, tax filings, and even patterns in digital wallet usage. The result is faster, more inclusive credit approvals, particularly useful for first-time borrowers and small business owners.
Fraud Detection
Reactive detection with static rules, often catching fraud after losses occur.
Proactive real-time anomaly detection, allowing institutions to flag suspicious transactions immediately and prevent losses.
Customer Service
Typically uses a one-size-fits-all approach through generic web portals and call centres. Customer support is available only during business hours.
24/7 intelligent chatbots and voice assistants deliver personalized service. Human representatives now focus on complex issues as a huge chunk of routine customer inquiries are handled by AI.
Wealth Management
Human advisors serve a limited number of high-value clients; limited scope of automation for portfolio management.
Robo-advisors use AI to offer low-cost investing advice to the masses, democratizing personalized portfolio management and financial guidance. This segment now represents 24% of AI fintech, amounting to a total of about $4.2 billion in market value.
Insurance Claims
Paper-driven, manual processing taking weeks; high labour costs and error rates.
Insurers use AI to flag fraudulent claims early, enabling faster payouts on genuine claims, drastically lowering operational costs while improving customer trust.
It is clear that AI is not incrementally enhancing existing processes in Fintech, it is redefining them entirely. To understand the scale of this transformation, we need to take a closer look at how exactly AI is reshaping different domains of financial services, from lending and wealth management to fraud detection, insurance, and beyond.
LLMs, Generative AI, Agentic AI and GraphRAG in Fintech:
LLMs are used in fintech to automate document processing, offer personalized financial advice, improve customer support, and enhance fraud detection. For example, JPMorgan Chase launched its LLM Suite portal, powered by OpenAI, to integrate external LLMs. Mastercard deploys generative AI to detect and block compromised payment card numbers faster by predicting full card details exposed through cybercrime tactics like spyware, malware, and card skimming.
Agentic AI empowers intelligent agents to independently perceive, reason, and act. In trading, these agents autonomously analyze market data, adjust strategies, mitigate risks, and integrate with tools via APIs for real-time decision-making. They automate tasks, optimize workflows, and automatically adjust portfolios based on market and client trends, thus enhancing efficiency and decision quality beyond generative AI.
Bridgewater Associates’ $2 billion fund uses machine learning and technologies like large language models for autonomous market analysis and strategy. It still relies on human oversight for risk and execution making it a hybrid of advanced AI decision-making and human supervision.
Graph RAG enhances fintech applications by leveraging knowledge graphs to structure and connect complex financial data, by incorporating knowledge graphs generated by large language models (LLMs). This can also enhance accuracy, explainability and reasoning for LLM applications. Standard RAG, which is a more traditional tool, retrieves and summarizes relevant documents for concise responses, while Graph RAG performs whole data set reasoning using knowledge graphs to deliver detailed, interconnected answers that reveal complex relationships. Human queries are complex and require connecting multiple data points, which traditional data methods often fail to capture without losing context. Graphs reflect human thinking by preserving rich relationships between entities, enabling RAG systems to provide more accurate, context-aware answers. Unlike vector-based retrieval that can miss nuanced connections, graphs maintain data structure for precise question-answer mapping. Lettria’s benchmarks showed GraphRAG improved answer correctness from 50% to over 80% across finance, healthcare, industry, and law datasets, proving graph-enhanced RAG’s superior accuracy.
