About
A small practice in Gyeonggi-do that helps application teams read customer behavior without turning every question into a permanent analytics hire.
Why we exist
Business applications collect more event data than most teams can interpret between releases. Product owners see charts; operations hears from support; engineering maintains tracking that drifts. DevData Sphere sits between those groups for a defined engagement and returns a reading of how customers actually behave inside the application.
Origin
The practice formed in Namyangju-si after years of reviewing funnel and path data for mid-size Korean firms whose applications handle orders, bookings, field work, or internal reporting. Clients did not need another vendor login. They needed someone to sit with the exports, ask awkward questions about missing events, and brief stakeholders in plain language.
How we work
We start from the questions that matter this quarter—approval delays, onboarding return rates, taxonomy chaos—then pull only the journeys and cohorts required to answer them. Findings arrive as written packs and live walkthroughs. We decline work that would require inventing metrics the application does not capture.
Who you meet
Engagements are led by analysts who have worked inside product and operations teams, not by a rotating bench of generalists. You will speak with the same people who read your data and write the brief. When a specialist workshop needs facilitation, we bring a second facilitator rather than hand the account to an account manager.
Values in practice
- Prefer provisional honesty over polished charts built on incomplete tracking.
- Name the customer action, not the control, when discussing events.
- Keep maps and cohorts ugly enough to show real detours.
- Leave documentation the client can maintain after we leave.
