James and Stephen meet Christina King, Chief Commercial Officer at Tribosonics, in a Steel City Business first - she's the first guest who neither of us had met before the recording.

Christina has had an amazing and unusual journey - from building tanks to breaking world records - which she shares with us.

We also talk Tribosonics, the tech scene in Sheffield and the north, and female leaders in the sector.

Steel City Business is brought to you by audio marketing experts Sound Media and supported by The Kurious. This episode was recorded at Ride Shotgun in Sheffield.
