We’re Capital on Tap

Capital on Tap started because small businesses were underserved. Big banks were slow, their products weren't fit for purpose, and small business owners often couldn't access what they needed. We set out to fix that.

Today we're a financial platform – not just a credit card company. We offer a best-in-class business credit card, SME-focused spend management platform, a savings product that hit £1 billion in funds within its first year, and a growing suite of tools and financial products that make running a small business easier.

1,000+ employees, £20bn in annual card spend, 200,000+ customers.

London, Old Street – 2 days in office.

At Capital On Tap, we run a hybrid embedded SRE model. We aim to work closely with the teams within Capital On Tap to provide them the best support. Our main objective currently is to gain visibility into our platform's health while offering scalable solutions.
