CUSTOMER STORIES 
Added value for our customers
Each story describes the starting situation, what changed and what measurable business results were achieved.
JR-Tools — Survey process turned into a growth tool
Situation: Analyzing customer feedback took a lot of time in manual Excel work, and upsell opportunities hidden in responses went untapped.
What changed: Survey creation and analysis sped up significantly and a lead collection stage was added to the survey. Management received clearer and deeper data to support decision-making along with prioritized action recommendations.
Result: One workday saved per survey, better data for decision-making — and leads collected from the first survey led directly to deals.
"With ZEF we saved one workday per survey and made better decisions on top of that. From the first customer survey we collected leads and made deals — ZEF paid for itself immediately."
Anfra — A silent signal prevented a people crisis
Situation: There was no real visibility into the state of management work. Risks were accumulating unnoticed — nobody knew what was happening beneath the surface.
What changed: Continuous EX measurement revealed a critical signal in management experience. The information triggered a targeted coaching program whose impact was tracked round by round.
Result: Manager NPS rose from −2 to +37 in eighteen months. The staff turnover risk was averted before it materialized.
"Without that information this development project would not have happened. And without those actions, employee turnover would certainly have increased."
ATA Gears — Three years of continuous NPS growth
Situation: Customer feedback accumulated from individual interactions and data was scattered. The international company wanted to develop customer experience systematically across different markets — as continuous learning, not isolated feedback.
What changed: ZEF became the foundation for continuous customer understanding. Results were monitored in real time and drilled down by respondent group across different markets. Each round brought a clearer picture of development needs.
Result: NPS grew from 57 to 65 over three consecutive years. Reports are generated quickly and decision-making is based on real data.
"We monitor customer and employee experience in real time and can drill into results by market area. Reports come out fast — it saves time and makes analysis easier."
Lumon — Revenue growth
Situation: Customer feedback was being collected, but referral leads were hiding in every survey — nobody was acting on them.
What changed: ZEF added a lead collection stage to the existing feedback flow. Promoters were automatically identified and asked for referrals; the sales team reached the leads within 24 hours.
Result: 230 quality leads, €130,000 in new deals in the first month, 14x ROI, payback period under one week.
"In the first ZEF month we made €130,000 in new deals directly through leads collected via customer feedback."
Lapin Kumi — Continuous readiness to anticipate
Situation: Lapin Kumi needed a continuous pulse meter for customer and employee satisfaction as the company grew — not a one-off measurement, but a permanent insight rhythm.
What changed: ZEF became a monthly feedback layer. Signals surfaced in time, problems were solved before they accumulated, and the feedback loop became part of the company's operating model.
Result: NPS 80+ for five consecutive years, profitable growth sustained throughout.
"ZEF has been our early warning system for five years. We don't wait for problems to show up in our metrics."
Doorway — Reputation rescue
Situation: Doorway's customers were satisfied, but nobody outside knew it. A 2.3-star Google rating was costing deals every week — bankruptcy was close.
What changed: Monthly feedback campaigns identified satisfied customers and automatically directed them to leave a Google review at exactly the right moment, while simultaneously collecting leads from the same promoters.
Result: Over 100 genuine five-star reviews in 6 months, rating up to 4.2 stars, website conversion +35%, bankruptcy avoided, 125x reputation ROI.
"Half a year earlier we were considering shutting down. When we had over 100 five-star reviews, everything changed."
Easoft — Customer retention amid growth
Situation: Easoft was growing, but churn was unexplained. Product decisions were based on internal assumptions; CX and EX were measured separately, if at all.
What changed: Monthly CX and EX feedback was cross-analyzed with product data — root causes were found, fixed and verified in a cumulative insight loop that sharpened with each round.
Result: 10x ARR growth in five years, 58% CAGR vs. industry average of 17%, NPS 80+ at every stage of growth.
"Five years later we have grown tenfold. I believe this tool accounts for 30% of that growth."
