The problem
You've sensed it for a while: there's something between picking stocks and just buying the index and hoping. A portfolio built for an uncertain future, one that doesn't rely on predicting it or on assuming the next decade repeats the last. Maybe you've even tried a few approaches.
But each time, the same wall:
You know real alternatives exist (all-weather, trend following, TAA) — but you're unsure how they actually work, and which are worth following.
Even when one looks promising, you don't have the time or experience to actually implement it.
And you can't test any of it properly — that takes time and coding skills.
And you've got no one credible to tell you whether you're on the right track, so you second-guess every move.
“How can I actually build something like this?”
The Solution
So here's the deal: We do the hard part.
You do the interesting part.
We do
the hard part
- Digging through the research
- Building the infrastructure
- Designing and stress-testing the strategies
- Making it all clear and actionable
You do
the interesting part
- Learning how it works
- Thinking it through
- Deciding what fits you
- Running it live

After a decade managing money, I've learned it always comes down to this:
The right research + the right tools + the right guidance = better decisions + a better portfolio
What InvestLab gives you
Live portfolios & strategies
Core portfolios and tactical strategies inspired by the best practitioners and backed by decades of evidence - with live allocations, transparent performance, and clear rebalancing rules.
Fewer strategies, higher conviction. Every one designed for robustness, not excitement - and every one showing where it struggles, not just where it shines.
Example strategies
Real-time strategy analysis
See what's actually driving each strategy: performance attribution, risk decomposition, rebalancing signals, and regime context. The kind of analysis that's normally locked inside institutional platforms.
Example analytics
Quant lab
Take any strategy and test it against decades of real data - stress-test it, break it apart, and see where it fails. Modify one to fit your goals, or build your own from scratch.
The point isn't to prove a strategy works. It's to understand it deeply enough to decide if you can stick with it.
Example tools
Institutional-quality research
The investing world is drowning in content. Most of it is noise. InvestLab focuses on what actually matters for your decisions - the real trade-offs, where each strategy breaks, and what's happening right now that affects how your portfolio behaves.
Every topic covers the process (how it works), the practical (how to implement it), and the behavioural (how to stick with it).

Become a Founding Member
10 founding members. We grow together.
I'm Stéphane Renevier, the founder and portfolio manager behind InvestLab. The strategies here come from a decade of running them - first with institutional capital (risk parity at Schroders, an $800M macro book at Wells Fargo), then with my own. The research and process aren't new. Making them accessible to serious individual investors is.
As a founding member, you get full platform access from day one: core portfolios, tactical strategies, and every tool to test, adapt, and build your own.
Then the part I can't offer at scale - and won't offer again:
Private community
A closed Slack group of 10 serious investors with direct access to me. Share your portfolio, ask anything, learn from each other.
Weekly deep dives
Live sessions where we build together, or written deep dives into strategies and advanced topics. Every week, something new.
1-on-1 onboarding
A dedicated session to understand how you invest, what you're building, and how to get the most out of InvestLab.
Founding Membership
founding rate, locked in forever
After launch, the founding membership disappears. What remains is the platform - no community, no direct access, no weekly sessions. At a higher price.
This is the only time I'll offer this.
This is for you if...
- You're stuck between too many ideas and no real portfolio decision
- You want a process that holds up - not just a portfolio that looks good in a backtest
- You care about robustness more than excitement
- You're ready to do the work and come out with something you actually trust
This is not for you if...
- You want hot tips, fast trades, or guaranteed outcomes
- You want sophistication without doing the work
- You want answers without understanding the trade-offs
Why I'm Building InvestLab
Most retail investors have the same goal: build wealth over the long term. The investing industry should help them get there. Instead, it sells noise, excitement, and unrealistic expectations - and leaves people with no process for when things go wrong.
I know because I've been on every side of this.
The obsessed retail investor
Reading everything I could find, building momentum and value strategies at 2am. I made every mistake you can make - and learned what it feels like to have no process, no tools, and no one to tell you what you're getting wrong.
A decade managing real money
Risk parity at Schroders. Alternative risk premia and tactical trading strategies at Wells Fargo. I learned how to build strategies from scratch, manage them under pressure, and how much of successful investing is process and discipline - not brilliance.
Working alongside individual investors
At Finimize, writing research for hundreds of thousands of individual investors. But I kept hitting the same limit: you can explain a strategy perfectly, and people still have no way to test it, build it, or run it live. That's the gap I couldn't stop thinking about.
Building InvestLab
My mission is simple: help retail investors actually reach their long-term goals. Not by telling them what to buy - but by giving them the guidance, the frameworks, and the tools to build a portfolio they understand and trust.
I want people to learn by doing - test strategies, challenge assumptions, make better decisions - and become better investors in the process, not just followers of someone else's picks.
I haven't figured it all out, and I'll always be upfront about the blind spots and weaknesses in what I propose. But I've spent a decade getting closer, I'm investing my own money through these same strategies, and I'm obsessed with getting this right.
InvestLab exists to close two gaps:
Gap 1
Retail → Professional-Grade
Research, frameworks, and tools at a level typically only available inside institutions - built so retail investors can actually use them.
Gap 2
Theory → Practice
Don't just understand momentum, risk parity, or regime-aware allocation in the abstract. Build it, test it, run it live - with real tools and real stakes. A learn-by-doing approach.
