I started my career as a finance manager, transitioned into product management, and now I’m building my own products.

Back in my finance days, while managing a £6M budget, I uncovered a £15k leak hiding in plain sight: FX fees.

Today, I see solo founders making the exact same mistake. I realised most founders are quietly losing 2-5% of their revenue to what I call the Lazy Tax: - Stripe's ~2% auto-conversion fee on inbound revenue, - plus their local bank's ~3% spread when paying for global SaaS tools (AWS, Claude, Ads).

So I built FixMyFX to show founders their exact leak and how to fix it (using multi-currency accounts to achieve a zero FX leak setup).

Initially, I had Claude build this in React. Realised a simple calculator shouldn't need a 150kb payload and a complex build process. Threw the React code away and rebuilt it as a single lightweight HTML file using Alpine.js and Tailwind.

It's completely free and ungated. I hope it helps you keep a bit more of your hard-earned revenue. Would love your feedback.

We built Ubik Studio because in professional research settings, or fields where accurate citation is required, AI tools kinda flop. Models hallucinate citations with total confidence and you are locked into one provider. Multi-hop tasks degrade in quality. Context engines fail on file-based work. And without step-by-step approval flows, humans now spend more time verifying AI work than doing the work itself, this is super strange.

We really believe that a successful AI use requires expert-level human judgment and verification. Researchers would rather work slower with certainty than fast and wrong.

Since we started building Ubik 2 years ago, we've focused on an assistive, human-in-the-loop design. We're model-agnostic and built-ready for the n

Do you remember usability testing?
