Introduction
Interamerican, part of Achmea Group, is one of Greece’s leading insurance providers, offering life, health, and property & casualty services. In 2010, the company launched a major IT transformation initiative to replace fragmented legacy systems with a modern, sustainable core insurance platform.
This case study highlights how SIG supported Interamerican throughout the years from early modernization through large-scale expansion and into its current focus on security and resilience.
The challenge: building a sustainable digital infrastructure for a new digital era
Interamerican needed a unified architecture capable of replacing decades of legacy systems while supporting both back-office operations and the next generation of customer-facing applications.
The company also faced the longstanding challenge of balancing cost, speed, and quality — a theme that shaped the entire engagement.
“We needed a digital platform that wouldn’t just replace our legacy landscape — it had to support the next decade of growth. SIG helped us set the right foundation from day one.”
Working with Software Improvement Group
SIG’s involvement spanned strategic guidance, continuous analysis with Sigrid®, and deep collaboration with both leadership and engineering teams.
Approach highlights:
- Continuous code analysis at every commit to track health, maintainability, and security.
- Twice-annual management reports to support CIO-level decision-making.
- Targeted advisory and refactoring workshops to address architectural and code-level issues.
- Custom secure-coding training, using the client’s own findings to build practical capability.
- Close collaboration with team leads and senior developers, supported by dashboards and KPIs.
Modernizing legacy infrastructures for long-term maintainability
From the start, SIG helped Interamerican define its transformation roadmap and establish development and architectural best practices. Using the Sigrid® software assurance platform, we conducted continuous code analysis to ensure the new systems were maintainable, extensible, and built for change.
Organization-wide commitment to software quality
Interamerican’s commitment to software excellence took root early. The company adopted SIG’s 4-star maintainability rating as an organizational KPI — even tying it to executive bonusses. This set a clear standard for quality from the top down.
“Interamerican was one of the first companies in Greece that was actually monitoring the security of the source code and the architecture… before this became a necessity or a regulatory obligation.” – Yiannis Kanellopoulos, Practice leader, SIG
Scaling across lines of business — and across countries
As Interamerican’s systems matured, the focus shifted from modernization to scalability.
The front-end platform (Anytime) and core system (One) expanded to support multiple business lines across life, health, property, and casualty.
These platforms became foundational to Interamerican’s digital strategy — and strong enough that Achmea began leveraging them in additional operating countries. What started as an internal transformation evolved into a multi-market digital foundation for the wider group.
Becoming a forerunner in digital insurance and security monitoring
Interamerican has been a consistent early mover in Greece’s insurance sector.
Anytime was among the country’s first direct-to-consumer digital insurance platforms.
Similarly, Interamerican was one of the first insurers in Greece to proactively monitor the security of its source code and architecture, long before security reviews became standard practice in the financial sector. Today, security KPIs such as high-risk findings and outdated libraries are tracked alongside maintainability as core performance measures.
“Being ahead of the curve on secure development was important to us. SIG helped us embed security into our daily work long before it became a regulatory requirement.”
Supporting a culture of software excellence
The development organization grew from roughly 30 to more than 100 engineers — driven by innovation and market expansion, not technical debt or “keeping the lights on.” Throughout this growth, the teams consistently maintained a 4-star quality rating.
Developers frequently noted how much easier it was to work in Interamerican’s codebase compared to others — a reflection of early architectural discipline and continuous quality monitoring.
Results: Sustainable growth through quality and insight
Over 15 years, Interamerican has built a secure, maintainable, and scalable digital platform that continues to grow in both functionality and geographic reach.
Key outcomes:
- Consistent 4-star maintainability rating over more than a decade.
- Development capacity expanded from ~30 to 100+ engineers, driven by new features and markets — not technical debt.
- Platforms now support multiple insurance lines and are leveraged by other Achmea operating countries.
- Security is embedded in daily development, supported by continuous monitoring.
- Clear visibility for leadership, supported by biannual reporting and actionable KPIs.
Interamerican’s journey shows what is possible when software quality becomes a strategic asset — not just an engineering concern.
Looking ahead
What began as a modernization effort transformed into a long-term partnership focused on continuous improvement. Together, SIG and Interamerican proved that it’s possible to balance cost, speed, and quality — and build systems that scale both technically and geographically.
Interamerican’s story stands as a testament to how sustained attention to code quality, architectural discipline, and secure development can unlock lasting digital growth.
