Getting software right for a healthier digital world

The world is becoming increasingly reliant on software. We all trust our businesses, homes and lives to it, but do we really know what it’s made of? Or that it’s trustworthy? At Software Improvement Group, we make software transparent. It’s our mission to create a healthier digital world by getting software right and establishing assurance.

We do this by measuring source code against our software analysis database – which contains more than 200 billion lines of code.
