Investors
Build your portfolio with AI, while keeping 100% control over everything.
We turn your ideas into automated trading strategies.
We're developing the tool we use for our own investments: a private manager in your pocket, on its own app or directly in ChatGPT, at lower cost: a fixed price (e.g., €0-10/month) instead of traditional 2% AUM fees.
Find investment opportunities matching your criteria with AI-powered search.
Test your strategies on 20 years of historical data before investing real money.
Execute your approved strategies automatically with your preferred brokers.
An agent that adapts to YOUR asset focus: you're not locked into pre-packaged portfolios by your banker. Every strategy is transparent and explained so you understand exactly what's happening. Financial expertise is now a commodity—accessible to everyone through AI, regardless of portfolio size.
You decide, Bubble executes.
Find the best investment opportunities with our AI-powered screening engine.
Test your strategies on 20 years of historical data before investing real money.
Automate execution of your strategies with your preferred brokers (IBKR, Alpaca, Saxo Bank).
Stay in control of your decisions. Bubble provides insights, not mandatory recommendations.
€0-10/month depending on your plan. No AUM fees, no costly intermediaries. Our interests are aligned with yours.
Starting with 200 000 EUR, Bubble's low flat-fee model (from 0 to 10 EUR/month depending on tier) keeps significantly more wealth compared to traditional 2% annual fees over 30 years.
Illustrative scenario: 200 000 EUR initial investment, 7% annual returns. Bubble example: 8 EUR/month fixed fee. Traditional: 2% annual fees.
While traditional fees grow exponentially with your portfolio, Bubble's 0-10 EUR/month pricing stays constant, maximizing your wealth accumulation.
Cumulative fees comparison over time. Fixed subscription remains constant while percentage-based fees grow exponentially.
AI breaks down technical jargon and dissolves elitism: expertise becomes accessible to everyone, allowing you to demand proof, challenge your financial advisors, and insist that fees reflect clear, transparent value.
Our ethics restore power to you and free you from excessive fees charged by obsolete intermediaries. Result: you finance the economy, the economy pays you interest. That's it.
Bubble is a conversational investment agent. You chat with it to:
1. Define your profile (goals, time horizon, risk tolerance)
2. Explore strategies (momentum, risk parity, value...)
3. Backtest your scenarios on 17+ years of data
4. Build your personalized allocation
5. Automate execution via your broker (IBKR, Alpaca, Saxo)
Everything is transparent: you see the calculations, rules, and historical performance.
All strategies are available in all plans. Bubble offers 9 backtested strategies:
• Risk Parity: risk balancing across assets
• Momentum: 3-12 month trends
• Value & Quality: fundamentals + quality screening
• Low Volatility: volatility minimization
• Equal Weight: equal weighting
• Custom Mix: combine multiple strategies to your preferences
Each strategy comes with explanations, historical performance, drawdowns, and Sharpe ratios. No limits by plan.
Currently, Bubble focuses on low-cost ETFs:
• Stocks: SPY (US), EFA (Europe/Asia), EEM (emerging)
• Bonds: IEF (US Treasuries 7-10Y)
• Commodities: GLD (gold)
• Real Estate: VNQ (US REITs)
• Cash: money market funds
• Cryptocurrencies: via Crypto.com and other crypto broker APIs
• Individual stocks: for targeted exposure
Structure: One strategy per pocket + one overall portfolio strategy.
No, never. Bubble does not hold your assets.
You keep your accounts with your usual broker (Interactive Brokers, Alpaca, Saxo Bank).
Bubble connects via API to:
• Read your positions (read-only access)
• Suggest orders (rebalancing, new trades)
• You validate each transaction before execution
You retain 100% control of your accounts.
Yes. Our conversational agent is designed to educate and guide:
• Plain language explanations: no technical jargon
• Predefined or custom strategies: choose from our proven strategies or create your own mix based on your preferences
• Personalized recommendations based on your answers
• Educational backtests: understand how each strategy behaves during crises
You don't need to be an expert in quantitative finance.
