Principal Project Manager
SIGNAL IDUNA
SIGNAL IDUNA Romania is part of the SIGNAL IDUNA Group, one of Germany's largest insurance providers with a heritage dating back to 1907. Serving over 13 million clients across Europe, the Group operates in Germany, Poland, Hungary, Switzerland, and Romania with a focus on health, life, and accident insurance.
In Romania, SIGNAL IDUNA has established itself as a leading innovator in the private health insurance sector since 2008. With 16+ years of market presence, the company achieved RON 424 million (~€85 million) in annual premiums in 2023, representing 16% year-over-year growth that significantly outpaces market averages. This positions SIGNAL IDUNA as the fifth-largest player in Romania's health and life insurance segment.
The company's competitive advantage lies in its Mediqa Net network of 1,400+ medical providers spanning all Romanian counties, combined with 24/7 customer support and a strategic focus on digital-first insurance delivery. Recent strategic acquisitions, including ERGO's Romanian subsidiaries in 2021 and a majority stake in Garanta Asigurări in 2024, demonstrate SIGNAL IDUNA's commitment to Romanian market leadership.

Headquarters
Market
Notable achievement
Romania's private healthcare sector experienced explosive 60-fold growth between 1997 and 2016, creating unprecedented demand for streamlined insurance services. As digital expectations accelerated, traditional phone-and-paper insurance processes became a competitive liability in an increasingly mobile-first market.
SIGNAL IDUNA faced several critical challenges that threatened their market position:
Complex bureaucratic procedures
Extended processing times
Network visibility gap
Fragmented payment systems
Limited self-service capability
Additional complexity came from:
Regulatory compliance
Legacy system integration
Multi-language requirements
Security imperatives
Scalability demands
Transform SIGNAL IDUNA into Romania's most innovative health insurance provider by creating a comprehensive digital ecosystem that eliminates administrative friction, provides instant access to healthcare services, and positions the company for European expansion.
SIGNAL IDUNA selected HyperSense based on our proven expertise in FinTech and InsurTech solutions, demonstrated capability in cross-platform development, and deep understanding of regulated industries requiring both technical excellence and compliance rigor.

HyperSense began with extensive user research and stakeholder workshops to identify pain points throughout the customer journey. We conducted interviews with policyholders, medical providers, and SIGNAL IDUNA staff to understand workflow bottlenecks, customer expectations, and operational constraints. This discovery phase informed our architectural decisions and feature prioritization.

Our development methodology combined Agile sprints with continuous stakeholder collaboration, enabling rapid iteration based on real-world usage patterns. We established two-week development cycles with regular demos, ensuring SIGNAL IDUNA leadership maintained visibility into progress while providing opportunities to refine requirements as market dynamics evolved.

Quality and security were paramount throughout implementation. We established comprehensive QA automation, implemented enterprise-grade security protocols, and ensured all development aligned with GDPR requirements. Our DevOps practices on AWS provided the scalable, reliable infrastructure necessary for mission-critical insurance operations.

Business Growth

Signal Care Assistant eliminated entire categories of administrative overhead that previously consumed significant resources. Routine tasks—policy lookups, document distribution, appointment scheduling support, claim status inquiries—moved from high-cost call center interactions to zero-marginal-cost digital self-service.
This operational leverage allows SIGNAL IDUNA to scale customer service capacity without linear staff expansion, while simultaneously improving service quality through 24/7 availability and instant response times. Claims processors now focus on complex cases requiring human judgment rather than manual data entry, improving job satisfaction while accelerating overall processing throughput.

In a market where many competitors still rely on phone-and-paper processes, Signal Care Assistant positions SIGNAL IDUNA as the clear digital leader in Romanian health insurance. The comprehensive mobile experience—from appointment booking through telemedicine to investment management—creates competitive moat that would require competitors years and significant investment to replicate.
This technological differentiation appeals particularly to younger, digitally-native consumers who represent the growth segment in private insurance markets, helping SIGNAL IDUNA capture market share among high-value demographics.

The modern, API-first architecture creates foundation for continuous innovation rather than a static solution. SIGNAL IDUNA can rapidly test new features, integrate emerging healthcare technologies, and expand service offerings without fundamental platform limitations.
The successful integration of wellbeing services, second medical opinions through Hilio partnership, and life insurance management demonstrates the platform's flexibility. This positions SIGNAL IDUNA to lead digital health insurance evolution rather than follow competitors, maintaining strategic advantage as market expectations continue advancing.

Digital interactions generate comprehensive behavioral data unavailable through traditional phone and in-person channels. SIGNAL IDUNA now understands which providers members prefer, common claims scenarios, geographic usage patterns, and customer journey friction points.
These insights inform network expansion decisions, product development priorities, and targeted customer engagement strategies—creating continuous improvement cycle that compounds competitive advantage over time.
User-centered design
Cross-platform consistency
Iterative development
Security & compliance first
Our microservices architecture with independent scaling proved particularly valuable during acquisition-driven user growth—high-demand services like appointment booking scaled automatically during onboarding surges while maintaining cost efficiency for less-utilized features.
The real-time synchronization across platforms within seconds of backend updates created seamless experience whether users switched between mobile and web or received appointment confirmations while away from the app. OCR integration for claims processing demonstrated practical AI application delivering immediate operational value rather than speculative future benefits.

This project showcased our expertise across multiple capabilities:
Custom software development
Mobile app development
Cloud solutions
