Number one on the new CEOs to-do list: Get Monzo monetised and cash generative.
People with a good income, good credit score and low credit utilisation should be able to see some form of decent sized offer for an overdraft, loan and credit card. If it is overpriced that is fine (let the user decide that), but let there be some kind of offer to most people instead of the current hugely over-cautious / coin flip approach which looks like it was broken at launch and never fixed.
As much as I dislike everything about the incumbents, you could take any one of their lending teams, transplant them into Monzo and they would be generating hundreds of millions in income from 4m users, yet Monzo’s lending team hasn’t got a penny to scratch their arse with after a couple of years of ‘iterating’ their approach.
Once the revenue is flowing then they can experiment with marketplaces, open banking etc. if that’s where they want to go.
