We are Software Improvement Group (SIG)

Empowering organizations to govern the software their business runs on, so they can move faster while staying in control.

Our purpose

Software shapes how quickly organizations can launch, scale, and adapt.

Yet many organizations still lack clear visibility into their technology, don’t know where investment is most needed, and struggle to control rising risks.

System outages, high costs, and failed modernization efforts were already common. Now cyber threats, compliance demands, and the rapid rise of AI have raised the stakes further.

Organizations need continuous control across their software landscape, plus clarity on where to focus first and what to change next.

Our growth

For over 25 years, SIG has helped organizations build continuous control through software portfolio governance.

Sigrid®—our software portfolio governance platform—gives organizations an objective view of their software portfolio and expert support to prioritize critical improvements, manage risk, and guide major software decisions.

That gives leaders a shared, objective picture of their software portfolio, so they can decide where to act first, reduce risk, and improve speed without losing control.

Our promise

We help organizations go faster—responsibly.

We do that by giving executives, architects, and engineering teams a shared view of the software portfolio, grounded in objective analysis and recognized standards. That makes it easier to prioritize the right work, control risk and cost, and make fact-based decisions about where to invest next.
