Banking as we know it is being rewritten — not by banks, but by startups.
In 2025, artificial intelligence is the engine powering a new generation of fintech innovators that are redefining how we save, invest, borrow, and even spend.
From automated wealth advisors to AI-driven fraud prevention, these companies are transforming financial services once dominated by legacy institutions.
Here are the top fintech startups using AI to disrupt traditional finance — and how they’re changing the game.
1. Upstart — Smarter Credit Decisions
Founded in 2012 by ex-Googlers, Upstart uses AI to make lending fairer and faster.
Instead of relying only on credit scores, its algorithm considers education, work history, and income potential to predict creditworthiness.
📊 Why it matters:
Traditional banks reject millions of potential borrowers simply because their credit files are “too thin.” Upstart’s AI fills that gap — approving loans that humans might overlook while keeping default rates low.
💡 Impact:
- Over $35 billion in loans issued
- Partnered with 50+ U.S. banks and credit unions
- Average APR reduction of 10% for approved borrowers

2. Plaid — Connecting the Financial World
If you’ve ever linked your bank account to Venmo, Coinbase, or Robinhood, you’ve used Plaid — even if you didn’t realize it.
Plaid’s AI-driven platform connects over 12,000 financial institutions securely, allowing apps to access real-time user data for payments, budgeting, and investing.
💬 AI’s role:
Machine learning helps detect fraud, monitor patterns, and ensure that financial data is shared securely.
📈 The result:
Plaid has become the invisible infrastructure behind the fintech revolution — enabling millions of users to control their finances with transparency and speed.
3. Zest AI — Revolutionizing Credit Underwriting
Zest AI focuses on a crucial question: Can artificial intelligence make lending more inclusive?
The startup uses machine learning models that evaluate thousands of variables per applicant, helping lenders reduce bias and approve more diverse borrowers.
🏦 Key stats:
- Partnered with 400+ lenders across the U.S.
- Clients have seen 15–20% fewer loan defaults
- Endorsed by the NAFCU (National Association of Federally-Insured Credit Unions)
Zest AI is proving that smart data can drive both profit and fairness in finance.
4. Kasisto — Conversational Banking AI
If you’ve ever chatted with your bank’s virtual assistant, it might be powered by Kasisto.
This startup specializes in AI-driven conversational interfaces that allow customers to manage finances through natural language — text or voice.
💬 Example:
You can ask:
“How much did I spend on groceries last week?”
And Kasisto’s AI will instantly respond with categorized spending insights.
🌐 Used by major banks like J.P. Morgan, Standard Chartered, and Mastercard, Kasisto’s platform enhances user experience while reducing call center costs.
5. TomoCredit — Credit Building Without Credit History
For immigrants, students, and young adults, traditional credit scoring systems can be a wall.
TomoCredit breaks that barrier by using AI to evaluate real-time spending behavior, not old credit files.
The result?
Instant approvals, no fees, and no credit check required.
💡 AI Application:
Tomo’s machine learning models assess financial habits — like cash flow, savings, and payment consistency — to create dynamic credit profiles.
📊 Impact:
Over 500,000 users in the U.S. are building credit through Tomo, proving that inclusion and innovation can go hand in hand.

7. Kensho Technologies — Wall Street’s Data Brain
Acquired by S&P Global, Kensho is one of the most advanced AI analytics platforms in finance.
It processes vast amounts of financial news, earnings transcripts, and economic data to generate real-time insights for traders and analysts.
🧠 Think of it as:
Bloomberg Terminal meets ChatGPT — but for institutional investors.
Kensho’s AI helps analysts understand how world events impact markets — predicting short-term volatility and identifying investment opportunities.
💬 Example:
When an earthquake hits Japan, Kensho can instantly calculate the likely effect on energy prices, supply chains, and regional GDP.
Final Thought
From personal finance to Wall Street, AI-driven startups are breaking old systems and creating smarter, faster, and more inclusive financial solutions.
