CLAL Insurance is one of Israel's oldest and largest insurance groups, writing across life, health, pension, P&C and long-term savings. In recent years CLAL has undertaken one of the most ambitious digital transformations in the Israeli insurance market — consolidating legacy cores, opening APIs, and re-platforming its customer experience.
This piece reflects on what CLAL got right, where the hardest friction points were, and what the rest of the market can learn.
Context: why transformation was unavoidable
By the late 2010s, CLAL — like most incumbent carriers — was running on multiple generations of core systems, each acquired through previous mergers or built in different decades. The result was predictable: duplicated customer records, inconsistent product catalogs, expensive integration-layer maintenance, and a customer experience that varied wildly by product line.
Transformation wasn't a luxury. The Israeli market's digital-native entrants (including direct-to-consumer and embedded players) were eroding margins on every line, and the regulator was actively pushing open-insurance standards.
The four pillars of the program
- Core consolidation. Multiple legacy cores rationalized onto a smaller modern footprint, with a clear roadmap for decommissioning.
- Single customer view. A master data layer built to unify identity, consent and communications across product lines.
- API-first architecture. Every core capability exposed via well-documented APIs to internal and partner consumers.
- Digital channels. Mobile-first customer and broker portals built on the new API layer — not bolted onto legacy UIs.
What went well
- Executive commitment. The program had consistent leadership sponsorship — the single biggest predictor of transformation success in insurance.
- Phased delivery. Rather than big-bang replatforming, the program shipped customer-visible improvements throughout — keeping the business behind the investment.
- Vendor ecosystem. CLAL chose to combine best-of-breed modern platforms (including partners focused on specific lines and specialty capabilities) rather than betting the farm on a single vendor.
Where the friction was
Three challenges stand out — and they are universal across large-carrier transformations:
- Data migration. Decades of legacy data, with inconsistent quality and ambiguous product definitions, is always harder than anticipated. CLAL was not an exception.
- Change management. Internal teams accustomed to legacy workflows need time, training, and re-designed roles. Transformation without HR alignment stalls.
- Regulatory alignment. Running in parallel with regulator policy changes (open-insurance, privacy, consumer protection) means moving targets. Modularity is your friend.
The most important transformation lesson is also the most uncomfortable: the technology is rarely the constraint. Data quality, change management and regulatory alignment are.
Lessons for the market
For other incumbent carriers contemplating similar programs, the CLAL experience offers a clear playbook:
- Commit to phased, customer-visible delivery. Multi-year invisible projects die.
- Invest in data quality early. Every later step depends on it.
- Choose an ecosystem, not a single vendor. Specialization wins in insurance.
- Align HR, training and role design with the technology roadmap.
- Keep the regulatory roadmap in view — transformation has to be regulation-compatible every step of the way.
The takeaway
CLAL's transformation is a reminder that insurance modernization is less a technology project than a coordinated multi-year program of business, operations and regulatory change. The carriers that will win the next decade are the ones taking that whole-picture approach — not just buying new software.
