About us

We’re a bunch of techies, creatives and friendly finance folk, who’ve run our own businesses and side gigs – and helped others do the same. So we’ve come together, with Santander’s backing, to shake things up.

What if doing expenses from paper receipts was as simple as snapping a selfie? And you could get a clear view of your finances with a simple heads-up?

We’re here to save you time. Cut headaches. Smooth hassles. To make repetitive admin, endless paperwork, and tedious typing into spreadsheets, a thing of the past.

So we’ve created a place – for quick answers and inspiration. Business owner to business owner. A growing resource from people who go through the same as you.

And we’re making an app – your pocket business helper. Always on hand to make working life simpler.
