The 2026 Fintech Stack: Every SaaS Tool a Modern Fintech Uses
Every fintech we know runs roughly the same 45 tools by year 2. Here's the complete stack — what to buy, what to build, and where the money actually goes.

Approximate total spend
For a ~50-person fintech running most of the above:
~$65,000–$130,000/month in SaaS ($780k–$1.5M/year).
This is roughly 8–12% of a typical Series A fintech's total OpEx. Tools you can't cut, tools you can consolidate, and tools you can defer are the categories to review quarterly.
The 5 tools we'd keep if we could only keep 5
If I had to strip a fintech down to 5 SaaS tools and rebuild from there:
- AWS (or GCP) — cannot ship without cloud infra
- Vanta — cannot sell to enterprise without SOC 2
- Datadog — cannot debug production without observability
- Alloy or Persona — cannot legally onboard users without KYC
- Stripe — cannot make money without payments
Everything else is optimization, not survival.
