Fintech: real-time payments and fraud without a second stack

Fast-growing fintechs outgrow their app database. A lakehouse with real-time pipelines keeps analytics and risk on one platform.

Cover illustration: Fintech: real-time payments and fraud without a second stack
Short answer

Fintechs can run real-time payments analytics and fraud detection on the Databricks lakehouse without a second streaming stack, using real-time pipelines, governed features and model serving on one platform. This suits small teams that cannot run several platforms, and it keeps fraud features and models governed in one place.

Key takeaways

  • One stack for batch, streaming and ML.
  • Fraud signals close to the moment of payment.
  • Smaller teams get less infrastructure to run.

Fintechs grow fast. Transaction volumes rise, new products launch, and regulators ask harder questions. The app database that worked at launch starts to slow down.

The usual trap

Teams add a streaming tool for fraud, a warehouse for reporting and a separate store for ML features. Each works. Together they are hard to govern and expensive to run.

One platform instead

  • Ingest: push payment events with ZeroBus Ingest or an existing Kafka feed.
  • Process: build fraud and monitoring logic in Spark Declarative Pipelines with real-time mode.
  • Serve: give product and finance teams self-service answers with Databricks SQL and Genie.
  • Build apps: use Lakebase for operational features that need Postgres next to analytics.

What good looks like

Compliance teams see prioritized alerts with context. Product teams answer funnel and retention questions themselves. Engineers maintain one platform instead of four.

Keep it lean

Fintechs rarely have large data teams. A dedicated pod that owns the platform end to end often costs less than hiring each specialist separately.

FAQ

Frequently asked questions

Can fraud detection run on the lakehouse?

Yes. Real-time pipelines, governed features and model serving on one platform score transactions close to the moment of payment.

Why does one stack matter for a small fintech team?

Fewer systems to run means less infrastructure work and faster delivery of new use cases.
