By adding financial services to their core offering, SaaS companies can open up new vertical markets and increase revenue per customer by 2-5x
Andreessen Horowitz : Tweets: @_pagarwal and @a16z Tweets: Pratik Agarwal / @_pagarwal : We've noticed growing “financial services” revenue for a few of our SaaS/B2B portfolio such as @zetwerk @chargebee @zenoti. Good to see detailed analysis on SaaS+Fintech by @a16z, highlights below 🧵 https://a16z.com/... ... @a16z : In vertical SaaS, most revenue comes from subscriptions. By adding fintech products and services, SaaS businesses can up revenue per customer by 2-5x. @kshenster, @astrange, @seema_amble, & @kimberlywtan explain how & why this can unlock new SaaS markets: https://a16z.com/...
Context & Ripple Effects
Andreessen Horowitz's thesis lands on top of two earlier data points in our coverage: fintech startups have rebuilt every layer of the banking stack, from core tech to KYC/AML, which is precisely what makes it cheap for a software vendor to bolt payments or lending onto its product. Meanwhile, Alex Danco's argument that SaaS recurring revenue may soon be securitized into debt products sketches where the money side of this goes next.
The timing matters for how the market reads it: 2020's SaaS fundraising cycle saw median Series C valuations rise 40% while revenue grew only 20%, so investors were already paying ahead of fundamentals. A credible 2-5x revenue-per-customer lever gives that gap a story.
First-order effects
- Vertical SaaS vendors named in a16z's portfolio — Zetwerk, Chargebee, Zenoti — can attach payments, lending, or insurance to existing subscriptions, monetizing transaction flow their software already touches rather than selling more seats.
- The named authors (@kshenster, @astrange, @seema_amble, @kimberlywtan) hand portfolio founders a playbook that converts each customer relationship into multiple fee streams.
Second-order effects
- Incumbent banks and payment processors get repositioned as white-label suppliers to software companies, competing on API pricing rather than brand — the same unbundling the banking-stack coverage describes.
- If fintech-attached SaaS commands richer multiples, competitors without an embedded-finance line face valuation pressure at the Series C stage, forcing build-or-partner decisions across the vertical-software landscape.
Third-order effects
- Combined with recurring-revenue securitization, the endpoint is software companies becoming lenders and insurers themselves — taking credit risk on their own customers' cash flows and blurring the line between SaaS vendor and financial institution.
- That structural shift eventually drags regulators in: when a vertical software company underwrites loans or holds float, it inherits KYC/AML and consumer-protection obligations that pure subscription businesses never faced.
The trend: As fintech infrastructure commoditizes the banking stack, the distribution layer — software that owns the customer relationship — is positioned to capture financial-intermediation margins, turning every successful SaaS company into an embedded fintech.
