The Berlin-based, app-only bank revealed in an interview that it has passed 160 thousand customers, with 80% of its customer growth coming organically.
With operations across multiple European markets including Germany, France, Greece, Ireland, Italy, Slovakia and Spain, Number26 faces strong competition from other 'online only' banks such as Fidor.
We’ve announced that we had 100,000 customers by the end of last year and now we’re a little more than 160,000 already. The last number we announced was 130,000. So you see that we have a growth that is one of the strongest for a retail banking product in Germany or I would even say in Europe. If you compare that to what we have spent on marketing — which is almost nothing, over 80% of our growth is driven organically — you’ll figure out that is the key.
