What's your biggest financial blind spot as a founder?

We built Money Magician because we kept being surprised by our own finances. Profitable months that didn't feel profitable, VAT bills that came out of nowhere, four apps open just to answer one question. Turns out we weren't alone.

Now that we're (almost) live, doesn't mean we stop being curious: what's the financial blind spot that caught you off guard as a founder or creator?

Every answer shapes what we build next.
