Above is an example of Monzo using the data they have on their customers to provide them with offers and spending recommendations.
Very similar to the idea of this thread but printed on paper instead of in app.
Also on multiple occasions during interview @anon91821566 has said that Monzo would be in a great position to provide customers spending recommendations from regular bills like insurance or phone and entertainment deals, and has even suggested Monzo could help provide alternate suppliers in app, by doing this they would earn revenue in a similar way that price comparison websites do.
If Monzo can earn money like this we will get better interest rates on our current accounts and ensure the service is free of charge.
