Working in ten languages simultaneously requires a lot of work and cooperation by a lot of different people. The Mbeya-Iringa Cluster Project is working together with a number of churches and organizations. These include the following:

• Anglican Church of Tanzania
• Baptist Convention, Tanzania
• Free Pentecostal Church of Tanzania
• Life Ministry
• Lutheran Church
• Mbalizi Evangelistic Church
• Moravian Church
• Presbyterian Church of Malawi
• Salvation Army
• Scripture Union
• Tanzania Assemblies of God
• Tanzania Episcopal Conference

The churches involved in the project have assisted in recruiting people for the various language teams, including a number of their own pastors. Several of the churches have provided office space for the teams, including the space currently used for the main office in Mbeya.
