We are Software Improvement Group (SIG)

Empowering organizations to enhance their software quality through deep source code analysis and tailored, strategic guidance.

Our purpose

Software is the backbone of the business world, yet software quality is often treated as an afterthought.  

With the rapid adoption of AI, the enormous resources drained by inadequate code, and escalating cyber threats, the stakes have never been higher. Yet many businesses still struggle with fragmented, reactive approaches to software quality, leading to mounting technical debt, security vulnerabilities, and an inability to adapt to changing needs.  

As AI integrates into nearly every industry, these risks and challenges are only multiplying. This is where we come in.  

Our growth

For almost 25 years, SIG has been a global leader in software quality assurance, supporting both traditional and AI-driven software portfolios.  

Our software assurance platform, Sigrid®, combined with expert IT consultants, analyzes source code against the world’s largest benchmark database to deliver actionable insights and recommendations tailored to evolving business needs.  

This clarity empowers organizations to take full control of their software environments, ensuring their technology is a driver of success, not a source of risk.
