Client stories & reviews
Notes from product leads and catalog editors who commissioned listening audits — including one engagement that did not go as smoothly as hoped.
Evening mix abandonment
“Portalhorizon mapped where our evening listeners abandoned curated mixes after three tracks. The audit named the playlist order problem we had been arguing about for months. We reshuffled the opening three songs and watched completion climb the following fortnight.”
— Mira Tan, product lead, regional streaming catalogue
Freemium listening depth
“The retention briefing showed our free listeners were finishing more tracks than new paid subscribers during commute hours — the opposite of what leadership assumed. That forced a quieter conversation about onboarding shelves rather than another discount campaign.”
— Hafiz Rahman, growth operations, indie streaming app
Playlist discovery under pressure
“We only bought the shorter playlist review. It was enough. Two editorial mixes that looked popular on impressions were leaking listeners at track two because the cover song never matched the genre promise. Fixing those titles mattered more than adding another homepage module.”
— Siti Noor, catalog editor
Extended story — festival release week
A Malaysia-focused streaming app asked us to audit listening during a major festive release window. Exports arrived two days late, and several event names had been renamed mid-week, which slowed the reading. Once aligned, we found skip clusters concentrated on autoplay transitions after sponsored tracks — not on the festival playlist itself. The product team adjusted the autoplay handoff and kept the editorial mix intact.
The mild reservation: communication during the delayed export week felt thin on our side. We have since added a mid-window check-in even when data is late, so clients are not left guessing.
