Transforming Fintech

Postlight brings the best of modern software development to banking and finance

For many years, if you wanted powerful fintech tools on the desktop, you had to build native Windows applications. Most of the finance world runs on legacy .NET and Windows applications that are hard to update and demand constant maintenance and upkeep.

The end result is always the same: Under-resourced technology teams supporting apps that no one loves, and frustrated business owners watching opportunity slip away.

A Critical Upgrade

Platforms that power today’s most scalable apps—from Uber to Amazon—are ready to revolutionize fintech. Postlight specializes in bringing modern, secure web platforms to enterprises across finance and banking.
