The team behind Investminder

The team behind Investminder

Thierry Marrec (CEO) & Nordine El Housni (CTO)

Two investors passionate about finance realized how much work it takes to invest well. We all faced the same roadblock: a clear goal, but no tool to take action. Investminder is the tool we wish we'd had: efficient, accessible, and educational. Beyond the code, our approach is sincere. We've created this platform to empower you to build a solid and controlled financial future.

A word from the founders

Thierry Marrec

CEO

"Like many investors who become passionate about Finance, I navigated between different strategies for a long time. I started by thinking I was smarter than others by starting with stock-picking (even though it's one of the most complex approaches), before seeking poorly understood diversification. I then experienced the limits of passive Buy & Hold, which imposes heavy drawdowns, then I increased my buying / selling frequency by suffering the noise of trading platforms and financial news designed to provoke emotional reactions. I created Investminder above all to discipline and professionalize my own approach. I have a conviction forged by experience: the alliance of a healthy investment universe and simple and systematic execution rules makes it possible to preserve capital during crises and optimize risk-adjusted returns. Without reaching the complexity of hedge fund quants, it is possible to do much better than the uninformed investor by simply respecting a few easy-to-understand rules. Driven by research and development applied to the markets, I modeled and tested all the pre-parameterized strategies in our library (from multi-asset rebalancing to dynamic trend following) to offer healthy and auditable foundations to our community. I also designed the ergonomics and interface logic so that everyone can model their own rules step by step, without coding. Investminder is the tool that Nordine and I developed to test this thesis: with method, transparency and without a black box, it is possible to obtain good performance on the financial markets, i.e. a good compromise between long-term profitability and serenity."


Nordine El Housni

CTO

"Fourteen years building systems that cannot afford to fail: distributed platforms, large-scale data processing, artificial intelligence applied to industry, for international groups across three continents. That work taught me something finance later confirmed: whatever isn't measured, reproducible, and auditable always ends up costing you. Alongside that, the stock market fascinates me. I trained in it, notably at Thami Kabbaj's TKL Academy, and arrived at a simple conviction: emotion is the investor's number one enemy. It isn't the markets that destroy capital, it's the fear that makes you sell at the bottom and the euphoria that makes you buy at the top. The only defense is a system: rules defined with a clear head, executed without hesitation. That's exactly what brought me together with Thierry, whom I met in Phuket at a school reunion — the same vision of investing, complementary skills. Investminder was born from that. My role is to make this rigor accessible to as many people as possible, in a white box: no hidden formulas, every rule readable, every backtest reproducible, every result explainable. Behind the interface, an engine capable of simulating decades of history in seconds and recalculating your allocations in real time, built natively for AI — so that it informs your decisions, never makes them for you."
