Platform

Composable modules on a single real-time ledger.

Kernhaven gives every product line the same foundation: one ledger, one product engine and one event stream. Start with a single module and add the rest without migrating again.

Back-office console

See your whole bank in real time.

Balances, postings and event health in one place, updated the moment anything changes.

Product tour

Built for every team in the bank.

Launch products without a release.

Product teams define rates, tiers, fees and limits in versioned templates. Simulate the impact on a staging tenant, then promote to production with four-eyes approval.
