[02] capabilities

One platform.
Every banking capability.

From savings accounts to commodities trading, Corniche supports retail, SME and specialised banking through composable capabilities built on a shared core.

[03] the platform

Solid core,
built to extend.

Corniche is a core banking platform built around composable services and stable, versioned APIs. Start with the capabilities you need today and expand the platform as your business evolves.

01 / SPEED weekly release

Custom features in weeks, not quarters.

We ship Corniche every week — continuously, without fanfare. Your feature request lands on Monday's standup and ships in one of the next few releases.

02 / INTEGRATIONS day-one

Pre-built connectors, ready on day one.

Payment rails, KYC providers, card schemes, accounting systems, BI tools — we've integrated them all before.

SEPA · SWIFT · Visa · MC // 40+ connectors
03 / SUPPORT founder-led

The senior engineers pick up the phone.

No L1 deflection scripts. Direct line to the people who built Corniche — when something matters, you talk to someone who can actually fix it.

Named engineer · 24/7 // no queues
04 / SCALE 10 → 10M

From ten accounts to ten million.

Multi-currency, multi-entity, multi-jurisdiction from day one. Corniche handles a single product launch or a full bank migration without architectural surgery.

Horizontally scalable // no rewrites
05 / PROCESS listening

Customer-driven development.

Every feature in Corniche exists because a real bank asked for it. Built by listening closely to customers for 20+ years — not driven by investor roadmaps.

Built by engineers,
close to the platform and the customer.

Megasol was founded in Uppsala more than two decades ago with a clear engineering focus: to build core banking systems close to both the code and the customer. That approach still defines how we work today.

Corniche has evolved steadily over time, shaped by real banking operations and long-term customer relationships. New capabilities are developed in close collaboration with the institutions using the platform — by engineers working directly with the product itself.
