About the Client

Jamkicks osakeyhtiö is a premier Finnish music playschool specializing in education for children aged 0–6. With over 30 locations in the Helsinki and Tampere regions, they offer "muskari" classes and band sessions designed to foster early childhood development through play. To extend this experience digitally, they launched Jamkids Musiikkimaailma, an interactive mobile app where children explore a musical world.

The Challenge

Jamkids required a highly reliable technical partner to oversee their specialized digital assets:

• Agency Transition: The project was originally developed by another agency. Jamkids needed a smooth transfer of the codebase to Reactron (and subsequently to Tekai) to ensure project continuity.

• Specialized Game Maintenance: The Musiikkimaailma app, built in Unity, required sophisticated performance tuning and bug fixes to maintain its high educational quality for young users.

• Operational Agility: Beyond core development, the client needed "hands-on" help with practical tasks, such as setting up seasonal digital campaigns and managing promotional codes to drive memberships.

Team & Approach

The engagement utilized a dedicated residency model, with Tung Trinh serving as the sole expert consultant. This model provided Jamkids with deep institutional knowledge as the partnership moved from Reactron to Tekai, ensuring a stable bridge between technical execution and business goals.

What We Built

• • Game Development & Refinement: Focused on the technical optimization of the Unity-based Jamkids Musiikkimaailma app, improving stability for interactive features and musical play.
  • Campaign & Promo Infrastructure: Developed and managed practical systems for digital promotions, allowing Jamkids to quickly launch marketing codes and track campaign performance.
  • Direct Strategic Support: Provided ongoing technical advisory to the Jamkids management team, acting as a flexible extension of their internal operations for all things digital.

How We Worked Together

The partnership was built on trust and direct communication. Tung worked closely with Heli Miinin and the Jamkids team to handle everything from urgent bug fixes to the logistical setup of promotional offers, ensuring a low-friction workflow.

Key Results

• Seamless: Successful long-term maintenance and transition of game assets from the previous agency.
• High: Sustained app performance and reliability for the Jamkids digital ecosystem.
• Efficient: Rapid deployment of promotional codes and technical campaign support.
