In the news
- Uncertainty isn't the biggest risk. Realizing its impact too late is. In a world where change is constant, finance can no longer afford to operate on yesterday's numbers. The future of finance is real-time: understanding what's changing as it happens, anticipating the impact, and acting while there's still time to make a difference. On November 4, I'll be joining the CFO Benelux Summit in Amsterdam for a fireside chat on Leading through uncertainty. A topic close to my heart, and at the core of what we're building at Peaky.

Sixteen years in finance and one thing still makes no sense to me. The business changes every day. Finance finds out last. Finance still has to explain it.

- A while ago it was just a beer and a crazy idea. And earlier this year we closed our €𝟭.𝟭𝗠 𝗳𝘂𝗻𝗱𝗶𝗻𝗴 𝗿𝗼𝘂𝗻𝗱 with Peaky. What a ride. 🤩 I come from design, not finance. But you don't need a finance background to see that something is broken when the people running a business are always the last to know what's happening in it. Peaky fixes that. A living financial plan that moves with your business and tells you what's changing before it costs you. Oh, and we were named Belgium's Best FinTech Startup of the Year. Still
- Driving at 120 km/h while looking exclusively in the rearview mirror sounds like a terrible idea, yet that’s how most companies still run their business. Traditional tools only tell you about the wall three weeks after you’ve hit it. Turns out, people prefer seeing the road ahead. Enter Peaky.
