What Tellmewow does
Tellmewow Studios, S.L. is a mobile game development studio headquartered in Bilbao, Spain, founded in 2015 by Urtzi Jaureguibeitia and Isabel Liébana. The studio develops and publishes free-to-play mobile games built on the Unity 3D engine, distributed globally through Google Play and Apple App Store. Its flagship product line, Senior Games, is a collection of cognitive stimulation games — covering memory, attention, reasoning, visual perception, and coordination — developed in collaboration with doctors and neuropsychology experts and targeting elderly players seeking mental exercise. The Senior Games brand claims over 230 million players worldwide, a 4.5 average rating, and a Top 1 ranking in the Brain Games category on app stores, with accumulated downloads across all titles exceeding 900 million. The company also operates the Edujoy sub-brand (educational games for children, developed in partnership with Playkids) and publishes hypercasual titles such as Word Planet, a multilingual vocabulary game.
Tellmewow monetizes primarily through in-game advertising served via Google AdMob, supplemented by optional in-app purchases for additional content or features. The studio operates a product-led go-to-market motion, with consumer acquisition driven by app store optimization (ASO), content marketing via its blog and social channels, and earned media through radio and trade coverage. A strategic distribution partnership with Bleta, established in 2020, pre-installs Senior Games on tablets designed for elderly users, providing a dedicated hardware channel into the senior demographic. The company is GDPR-compliant and adheres to EU data protection regulations. Marketing talks and beta-tester recruitment events are used for community engagement and product validation.
The studio operates with a small team (1-10 employees) and is part of Sandbox International Holdings Ltd. (Sandbox & Co.), an international mobile gaming group that also owns Playkids. Tellmewow has received regional innovation awards including the Bizkaia Award, BIG Award, Buber Sariak (for the Euskalmoji keyboard project), and selection for the Yuzz young entrepreneurs program in 2016. The company continues to actively operate, with a Data Analyst role posted in 2025 signaling ongoing organizational investment.
