The EVSORA difference
Off-the-shelf bends your business. Custom bends to it.
Traditional software
Business adapts to the software
- One-size-fits-all features
- Per-seat fees that compound
- Brittle integrations
- Vendor lock-in
- Slow vendor roadmaps
EVSORA
Software adapts to the business
- Workflows shaped to your operations
- You own the code, forever
- API-first, composable architecture
- Cloud-portable, standards-based stack
- Ship in 2-week iteration cycles

Case study
Northwind Payments. A $4.2B/yr rebuild in 7 months.
Problem
A 14-year-old monolith was capping settlement at 800 tx/s, lacked multi-currency support and required 6-month release cycles. Regulator deadlines were 9 months out.
Solution
EVSORA designed an event-sourced ledger on Go and Postgres, fronted by a React operator console. Treasury workflows were extracted into composable services; legacy integrations were strangled module by module without downtime.
