Build your portfolio with AI assistance while keeping 100% control over your investment decisions.
You decide, Bubble executes.
Starting with 200 000€, Bubble's low flat-fee model (from €0 to €10/month depending on tier) keeps significantly more wealth compared to traditional 2% annual fees over 30 years.
Illustrative scenario: 200 000€ initial investment, 7% annual returns. Bubble example: €8/month fixed fee. Traditional: 2% annual fees.
Traditional investing stacks multiple fees across actors. Bubble replaces them with one flat subscription and full transparency, made possible by automation and intelligence amplification through AI.
While traditional fees grow exponentially with your portfolio, Bubble's €0–10/month pricing stays constant, maximizing your wealth accumulation.
Cumulative fees comparison over time. Fixed subscription remains constant while percentage-based fees grow exponentially.
Today's journey is fragmented and incentive-misaligned. Bubble brings everything together as a transparent decision-support platform that explains every step, equips you with analytics, and keeps you in control from onboarding to monitoring.
Traditional path: bank appointment (waits, limited hours) → biased advice (commission-driven) → "house fund" selection (expensive, underperforming) → delayed reporting → hidden fee cascade. Bubble path: instant AI answers, transparent strategies with commentary and backtests, automated monitoring with exportable instructions you execute with your own broker.
Until now, you paid a money manager or a banker for reassuring words and a jargon that few understand. Today, AIs make the "technical" vocabulary free, readable, verifiable, and comparable. The elitism of knowledge and obsolete intermediaries are over.
LLMs (ChatGPT, Gemini, Claude...) democratize access to expertise, help you understand more clearly, and let you demand evidence. Fees must now reflect real value: useful insights and measurable outperformance. We pierce the financial bubble, lift the veil on fee opacity, and put value back where it belongs: with you.
Our ethics: putting power back in your hands so you can break free from the excessive fees of now‑obsolete intermediaries. The result: you finance the economy, and the economy pays you interest. That's it.
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.
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.
A fixed cloud-tool subscription (plans from €0 to €10/month) instead of a percentage of your assets like a traditional manager (2% fees). The hedge‑fund approach becomes accessible to portfolios of any size.
Bubble's conversational AI translates complex analysis into clear decision support so you can review scenarios and choose the next step yourself.
Our portfolios prioritise low-cost ETFs and extend to cryptocurrencies on our roadmap (Crypto.com integration in progress).

ChatGPT can discuss finance, but cannot:
❌ Access your real-time portfolio data
❌ Backtest strategies on 17+ years of historical data
❌ Connect to your broker to execute orders
❌ Monitor your positions and alert you to rebalancing needs
Bubble is a specialized agent with access to market data,
backtesting engine, and broker integrations. ChatGPT is a generalist.
