Most of our engagements are remote-first. Read-only analytics access and a shared document usually beat a long commute for inventory work.
On-site sessions still help for KPI alignment and experiment clinics when stakeholders disagree in person more productively than on video.
From Hanam we regularly work with teams in Seoul, Seongnam, and further afield. Language of deliverables is English; bilingual facilitation can be arranged when scoped ahead.
Application analytics is portable. What does not travel well is an undefined decision owner — fix that before you book travel.
