The Convergence of AI and SaaS: Who Will Win in Fintech?

April 22, 2025

Written by

Today, we are seeing SaaS companies increasingly use AI technologies to deliver a higher intelligence application vs. simply being a workflow tool or system of record. This evolution from cloud application (e.g., the internet) to intelligent application (e.g., early AI) to eventually autonomous application (e.g., AGI) will cut across industries and functions, including healthcare and fintech.

Just like software was eating the world 10 years ago, the next evolution is AI permeating every business model, function, and vertical. As AI as a service (AIaaS) moves into – and potentially takes over – the SaaS space, we see the potential for AI to move the SaaS category from a one-size-fits-most category to a more customizable set of tooling for customers. It will allow businesses to scale more than ever before and streamline infrastructure and systems in a way we’ve never seen. 

The Oak team’s experience investing in the companies that have changed the way we think about software, SaaS, and technology began nearly 40 years ago. When backing category-defining organizations, we look for not only generational founders, but also companies that understand broader market dynamics and are best positioned to capitalize on shifting trends in how businesses and consumers fundamentally operate. Whether it was the advent of cloud computing or the mass adoption of AI, the investment team uses its intuition and experience to match these trends to exceptional founders so that we can find the companies we want to support. 

In this two-part series, we are exploring what categories of companies we think are best positioned to win as SaaS and AI converge, starting with fintech. Fintech is inextricably tied to software – but identifying where SaaS and now AIaaS is best suited to unlock new markets hasn’t always been obvious, particularly as the fintech space cooled. 

When looking across our portfolio, and specifically at what we think is best positioned to win in the fintech AI space in the near-term, we are most excited about three categories: 

  • Vertical Applications: Across both SaaS and AI, vertical applications still add meaningful value in highly regulated industries, where there is a high bar for understanding a complex set of ever-changing rules and related compliance. And, in a world where fine-tuning and reinforcement learning still is best managed by humans-in-the-loop, vertical applications offer a solid near-term bet of category stand outs in fintech.
  • Horizontal Platforms: Within fintech, horizontal platforms that are exploring interesting ways to integrate AI into how they enable embedded finance, particularly those that offer low-code or no-code solutions, are best positioned to scale as companies get more comfortable with AI in the financial services sector.
  • Fraud: Fraud is still one of the biggest challenges in financial services, with the sophistication of AI only increasing exposure for companies and individuals alike. Companies that can match the technological advancements of fraud attempts with their own use of AI are best positioned to win. 

Looking across our portfolio, some of our software and AI investments in fintech map to these categories in the following ways:

Vertical Applications 

Vertical applications in SaaS were able to transform industries and win against horizontal companies because of their laser focus on the end user. Vertical AI applications can take this progress even further – tackling the language-based tasks and workflows within verticals dominated by regulatory requirements and unlocking a new, larger TAM. However, unlike their SaaS predecessors, vertical AI companies need multiple moats to win, including proprietary training data, high-quality user feedback, familiar UI, and early market presence. Our portfolio includes a cross-section of companies with these qualities. 

Auger, a new Oak portfolio company, is creating a unique software platform that will redefine supply chain management by helping customers manage planning, forecasting, and financing with greater ease.

Cart.com, a leading provider of omnichannel commerce and logistics solutions to help organizations with order and inventory management, uses enterprise-grade software, services, and logistics infrastructure to offer fulfillment as a software service.

Horizontal Platforms 

A horizontal fintech platform supports multiple verticals by solving common problems those verticals share. From data infrastructure to embedded finance to service-focused software platforms, in an AI-native world, horizontal platforms still offer companies exceptional ability to add features and scale to their organizations. 

Ocrolus is an automation platform that uses AI and reinforcement learning to analyze financial documents and provide actionable analytics for confident, high-quality credit decisions across small business, mortgage, and consumer lending.

Fraud

As financial institutions face increasing fraud risks, with 90% reporting fraud losses of up to 9% of their annual revenue, companies are looking to AI to combat the threats. In many cases, AI offers the only set of tools to keep up with the pace of threats and bad actors. Within the portfolio, we are focused on backing companies that take an AI-native approach to fighting fraud and supporting revenue recovery.
