How AI Will Transform Fintech In 2026

Fintech went from a full-blown surge to a near standstill in just two years. At its peak, about 25 percent of all venture dollars were pouring into the category. By late 2022, that number had collapsed to almost zero. In this conversation, a16z General Partner David Haber and Plaid cofounder and CEO Zach Perret unpack what actually happened during that cycle and why the market is heating up again. We explore how the industry moved from the explosive growth of 2020 and 2021 into a deep freeze, and why we are now seeing real momentum return. We also dig into the forces reshaping fintech today: AI’s outsized impact on fraud and underwriting, incumbents finally embracing external software, the renewed importance of deposits, and the rise of embedded finance across entirely new categories. Zach shares how Plaid has navigated these shifts, what the company is building now, and how he sees the next phase of fintech taking shape Timecodes: 0:00 FinTech’s Seasons 1:10 The Rise of FinTech (2014–2019) 3:32 COVID-19 and the FinTech Boom 4:43 Venture Capital Surge and FinTech Summer 8:25 Solving the Access Problem 10:41 Is Crypto Fintech? 13:51 Plaid’s Evolution and Industry Impact 17:26 Consumer Behavior and Adoption 21:48 Global FinTech Expansion 27:43 2026 Predictions: AI and Fraud 40:26 Emerging Trends in Fintech 43:34 Plaid’s Anti-Fraud and Credit Innovations Resources: Find Zach on X: https://x.com/zachperret Find David on X: https://x.com/dhaber Stay Updated: If you enjoyed this episode, be sure to like, subscribe, and share with your friends!

  1. 0:00 – 1:10

    FinTech as “Seasons”: framing 2014–2024 cycles

    Zach and David set up a “seasons” metaphor to explain how fintech moved through distinct macro- and sentiment-driven phases. They outline how funding, growth, and company behavior changed as the market moved from spring to summer euphoria, then into a sharp winter and back to spring.

  2. 1:10 – 3:32

    The rise of consumer fintech (2014–2019): digitizing the bank branch

    They revisit the early wave of fintech innovation where startups unbundled bank products and delivered them digitally. This era produced breakout apps and many niche neobanks, alongside early mainstream crypto consumer applications.

  3. 3:32 – 4:43

    COVID shock → fintech boom (2020–early 2022): “EDM summer”

    COVID initially froze activity, then quickly triggered a massive inversion where digital finance became essential. The result was hypergrowth for many fintech companies and a rush of capital from both private and public market investors.

  4. 4:43 – 8:25

    Venture capital surge and the abrupt drought (2021–2023)

    They highlight how extreme capital allocation created distortions—followed by a dramatic pullback as conditions changed. The discussion ties the boom/bust to both macro rates and business-model sensitivity, especially for lending-led companies.

  5. 8:25 – 10:41

    Rates, business models, and going “full stack” (deposits over lending)

    David explains how the rate cycle pushed fintechs to diversify revenue away from lending origination and toward deposits/float. Many leading fintechs pursued charters or acquisitions to control more of the stack and stabilize economics.

  6. 10:41 – 13:51

    From startup category to mainstream infrastructure: embedded finance everywhere

    Zach argues fintech has become synonymous with financial services—and even extends beyond it via embedded finance. Non-financial brands integrate financial capabilities, while banks reposition themselves as major technology companies.

  7. 13:51 – 17:26

    Solving the access problem—and the next horizon: making finance excellent

    Zach outlines “V1 fintech” as access: digitizing and expanding availability of services. The next wave shifts from access to quality—fixing deep structural issues like credit decisioning and fraud, using richer cash-flow data and better logic.

  8. 17:26 – 21:48

    Is crypto fintech? Convergence with banks vs frontier experimentation

    They discuss crypto as partially overlapping with fintech: it often maps to stable consumer behaviors (speculation, prediction, spending/saving) but introduces new rails and novel primitives. The likely path is convergence in areas like stablecoins and tokenized assets, while more experimental crypto remains separate.

  9. 21:48 – 27:43

    Plaid’s evolution: from bank linking to analytics, trust, and product velocity

    Zach walks through Plaid’s phases: early focus on account linking, then navigating the Visa acquisition attempt during COVID, and later refocusing as an independent company. He attributes recent acceleration to reaching data scale for analytics and improving the ability to ship products faster.

  10. 27:43 – 40:26

    Consumer adoption limits and the “self-driving money” debate (agents & trust)

    They explore whether agentic personal finance will finally work, noting a gap between power-user desire and mainstream trust. Plaid’s approach is to build safe primitives—data linking and actioning—then watch emergent behavior and mitigate new risks.

  11. 40:26 – 43:34

    2026 prediction: AI accelerates fraud—and fraudsters may lead adoption

    Zach predicts financial fraud will grow even faster as AI empowers scammers, calling it the biggest AI use case in finance today. They discuss the cat-and-mouse dynamic, the rise of deepfakes and social-engineering scams like pig butchering, and why this is uniquely hard to stop.

  12. 43:34 – 45:37

    What’s emerging now: software-led fintech selling into incumbents + Plaid’s new products

    David explains a16z’s current focus on software solving manual workflows inside large institutions, where AI expands the addressable market from IT budgets to labor replacement/augmentation. Zach closes with Plaid’s near-term bets—anti-fraud and modern credit scoring—and how fintech feels like early-to-mid spring again.
