About Yumesorai
The systems that move the world deserve to keep moving
Yumesorai was founded by engineers from Fortune 100 companies who spent decades inside the mainframes that run healthcare, airlines, and banking — and built the AI platform they wished they'd had.

What we believe
Map before you move
No migration starts until the knowledge graph shows every call chain, data flow, and black-box. Surprises belong on the map, not in production.
Verify everything
AI writes the code; parallel-run reconciliation proves it. Every transaction is compared against the legacy system before cutover.
Fair prices, all sizes
Enterprise-grade modernization shouldn't be reserved for enterprises. Our engagement models fit SME and MSME budgets.
Built by the people who ran these systems
Our team has shipped and operated mainframe systems at Fortune 100 healthcare, airline, and banking companies. We have carried the pager for nightly batch runs, debugged CICS abends at 3 am, and watched institutional knowledge walk out the door with every retirement. That is why Yumesorai captures the knowledge first — and modernizes second.
