Ninth Wave Tech Stack

Open finance API connectivity platform for financial institutions

Financial Services New York, NY 51–200 employees Founded 2018 Privately Held

Ninth Wave operates a data connectivity layer for banks and financial services firms, built on Java/Spring with SQL Server and AWS infrastructure. Active projects reveal a company in mid-architecture transition: reverse-engineering legacy database schemas, redesigning for query optimization, and simplifying third-party integration experiences. The pain-point stack (modernizing legacy databases, reducing time-to-market for integrations, scaling database architecture) signals that Ninth Wave is managing both internal technical debt and external developer friction — two sides of the same platform problem.
