JustPlay Tech Stack

Adtech infrastructure for play-to-earn gaming with first-party games and automated payouts

Entertainment Providers Berlin 51–200 employees Founded 2020 Privately Held

JustPlay operates the full stack of rewarded mobile gaming: advertiser demand, player offerwall, payouts, and proprietary games. The tech stack is analytics-heavy (BigQuery, Snowflake, Looker, Tableau, Metabase, XGBoost) and game-focused (Unity, Kotlin), but hiring is bottlenecked — only 2 roles posted in the last 30 days across 18 open positions, with product roles (8) outnumbering engineering (1). This mismatch between the complexity of scaling a multi-title games portfolio and minimal engineering velocity signals internal constraint on technical scaling.
