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.
Payment rails, KYC providers, card schemes, accounting systems, BI tools — we've integrated them all before.
No L1 deflection scripts. Direct line to the people who built Corniche — when something matters, you talk to someone who can actually fix it.
Multi-currency, multi-entity, multi-jurisdiction from day one. Corniche handles a single product launch or a full bank migration without architectural surgery.
Every feature in Corniche exists because a real bank asked for it. Built by listening closely to customers for 26 years — not driven by investor roadmaps.
A broad set of banking capabilities, delivered through a unified platform and stable, versioned APIs.

Payment rails, KYC providers, card schemes, BI tools. Most common connectors are pre-built — we plug you in and verify end-to-end.
A new payment rail, a novel product type, a jurisdiction-specific workflow — when you need something that doesn't exist yet, we build it into your Corniche.
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.
Whether you need a technical walkthrough or direct access to our API documentation, discussions start with the team working on the platform itself.
