Over 10 years of listening across the customer lifecycle.
Salt is one of Switzerland's three mobile network operators, serving more than 1.8 million postpaid mobile and over 300,000 broadband customers. For more than a decade, it has relied on sandsiv+ to hear from customers at every major stage of their lifecycle.
Two types of survey, every channel, four languages
Salt runs two types of survey, transactional and relationship. Transactional surveys capture feedback right after a touchpoint, such as a shop visit. Relationship surveys measure sentiment across the wider customer base.
Together, they surface the pain points that drive the company's continuous improvement cycle. All channels and all four languages (German, French, Italian and English) run on the same platform.
Business-managed
Survey management sits in-house, with Salt's own team. New surveys go live quickly and can be updated whenever needed, without a vendor project in between.
Because Salt uses the full suite, unlocking a function never requires a commercial negotiation. The focus stays on acting on what customers say.
“After more than ten years, it’s about reliability and ease of use. sandsiv+ is a stable interface with very fast, agile support, and our business can launch and adjust surveys on its own with very short lead times.”
