Documented cause
Tandem Bank, a UK challenger bank and personal finance app founded in 2014, raised £72M and secured a banking license in 2017. In January 2018, House of Fraser — which had committed £29M — pulled its investment amid its own financial difficulties. This created an immediate capital crisis. Tandem was forced to sell its current account book to Interbank and pivot to savings-only, effectively ending its original personal finance vision. CEO Ricky Knox departed.
Lesson
“Never allow a single anchor investor to represent more than 30% of committed funding.”
