I’m Marcel, and Mars Money Lab is my personal UK investing lab on marsmoneylab.com. I run real portfolio experiments with real pounds, write down what happened, and publish the updates in public.
I am not a financial adviser. This is my own money and my own notes. Results vary. You can lose money. Do your own homework before you copy anything.
What I publish
Each experiment is a live test with a start date, a page on this site, and regular Updates Hub posts. The Experiments Dashboard shows the current picture. The Updates Hub is where the dated write-ups live.
Examples of what I track (not a promise of returns):
- Long-term stock and ETF buys (including Tesla and dividend ETFs)
- Crypto weekly buys
- Plutus rewards and gift-card / credits tests
- Outplayed matched betting
- NS&I Premium Bonds
- Everyday banking tools that keep the lab moving (for example Monzo)
Current numbers live on the dashboard and in the dated Hub posts.
Why this site exists
I started Mars Money Lab to see what works for me beyond my regular job, and to keep an honest public trail of wins, flat months, and misses. If an idea is passive, unusual, or just worth a careful try with small money, I may test it and say what happened.
Ideas welcome. Follow along on X @MarsMoneyLab.
