Analyst Report  ·  Gartner® Magic Quadrant™

Software Improvement Group recognized as a Leader in the Gartner® Magic Quadrant™ for Technical Debt Management Tools.

The first-ever Magic Quadrant™ in this category.
As AI tools generate code faster than teams can review it, architectural debt accumulates in the gaps. Architectural debt is the blind spot. Portfolio-wide governance is the answer.

80%
Gartner predicts that by 2027, architectural debt will account for 80% of all technical debt.

SIG’s architectural advantage

Architectural debt is distinct from code-level issues. It lives in the relationships between systems — how components are linked, how teams depend on each other’s work, whether software structure still matches design intent. AI tools compound this problem. SIG has been solving it for 25 years.

“Technical debt management has evolved from a niche engineering concern into a strategic business priority. As AI accelerates software creation, organizations need visibility into architectural drift, maintainability, security risks, and long-term software sustainability more than ever before.”

Luc Brandts — CEO, Software Improvement Group

Why this report exists

AI writes code at scale.
Architectural debt is
the blind spot.

AI coding assistants operate within bounded context windows. They generate code without understanding how it fits into your broader system. The debt accumulates faster than any team can see — let alone govern.

01 —
Code-level tools have a blind spot.

AI coding assistants are increasingly effective when it comes to code-level debt. But the market is shifting toward a harder problem: architectural debt. This debt lives in the relationships between systems. You need portfolio-wide visibility to see it.

02 —
AI compounds the problem it can’t see.

AI coding tools operate without domain knowledge of your broader system. They fill architectural gaps independently, without understanding downstream consequences. The result: debt accumulating at machine speed, invisible to machine-level tools.

03 —
25 years of evidence. One clear picture.

SIG has analyzed 400 billion lines of code across 30,000+ systems. That evidence base is what Sigrid® is built on — not just alerts, but context, industry benchmarks, and a clear path to remediation.
