What clients say after the walkthrough
The atlas made our Q3 churn spike legible for the first time — we could point to the exact week partner-acquired annual plans started leaving after the price change.
— Yoon Seoyeon, Head of Product, meal-kit subscription (Busan)
Kwon walked our CFO through the survival curves without once saying \"dashboard.\" She left with three questions for the CS team, which was exactly what we needed.
— Marcus Lindqvist, Finance Director, language-learning boxes (Stockholm, remote client)
The charts were precise and beautifully formatted. I wished the data reconciliation week had started sooner — we lost a few days waiting on our billing export.
— Park Jiwon, VP Customer Success, B2B SaaS billing (Seoul)
