Hello! I'm Doyoung Park

I’m a gamer, and a marketer who acts on data.
I’ve spent over five years running publishing pipelines across Korea, Japan and Europe, and building KPI frameworks from scratch. Beyond that, I’ve led product, investment and budget decisions grounded in market and performance data.

What I do? (and love doing)

My core strength is understanding users and content through data, and using those insights to improve and manage key metrics. Throughout my career, my main role has been analysing user behaviour and content characteristics to draw out insights, then testing and validating them to build insights and pipelines that genuinely move the metrics.

    Beyond the marketing.

    I sourced global partners and, through repeated meetings, game shows and negotiation, signed a China publishing deal.

    At SANDY FLOOR I set up and ran the market test for a new title, Dark Bouncer, from A to Z. I then used marketing and in-game metrics to propose a business-model pivot that was actually adopted, which secured a separate marketing investment for the domestic market.
