Two Different Products for Two Different Needs
The fundamental difference between DonkyCapital and Curvo is that they solve different problems. Curvo is for investors who want someone to manage a pre-built ETF portfolio for them. DonkyCapital is for investors who already manage their own portfolio and want a powerful tracker.
- Choose Curvo if: You want a simple, managed ETF investment account without choosing individual funds, and are happy to pay 0.5% annually for portfolio management.
- Choose DonkyCapital if: You already invest via DEGIRO, Scalable Capital, Trade Republic or other EU brokers, choose your own ETFs, and want a unified analytics dashboard across all your accounts.
Scalable Capital users: DonkyCapital offers a free browser extension that exports your full transaction history without paying Prime+ (€4.99/month) — so you can track everything without extra costs.

Analytics: Backtest vs Live Portfolio Intelligence
Curvo's analytics strength is backward-looking: its backtesting tool is excellent for simulating historical returns. DonkyCapital focuses on forward-looking live portfolio intelligence:
- ✓AI ETF Look-Through: DonkyCapital analyses the underlying holdings of your ETFs to calculate your real geographic and sector exposure. If you hold a global ETF, it shows you the actual 60% US / 15% Japan / 8% UK split — not just the listing exchange.
- ✓Portfolio Risk Score: DonkyCapital calculates a composite risk score factoring in volatility, sector concentration and geographic concentration across all your holdings. Useful for passive investors who want to avoid unintentional over-concentration.
- ✓Unified Dividend Calendar: All dividend payments across all your brokers in a single calendar — past and upcoming. Curvo's managed portfolios handle dividends automatically; DonkyCapital gives you full visibility across self-managed accounts.
Pricing Comparison
Curvo charges a 0.5% annual management fee on your invested assets. On a €50,000 portfolio that is €250/year. There are no transaction fees, but the management fee applies as long as assets are invested.
DonkyCapital is completely free during Accesso gratuito with no transaction limits, no feature tiers and no credit card required. It is a pure analytics tool — you keep investing with your existing broker at zero additional cost.
Verdict: Which Should You Choose?
Choose Curvo/NANAK if you want a simple, hands-off ETF investment product and are comfortable paying 0.5% annually. It is an excellent choice for investors who want to delegate portfolio construction and just automate monthly contributions.
Choose DonkyCapital if you already invest via one or more EU brokers, want to keep full control over your asset selection, and need a powerful tracker that aggregates everything in one dashboard. The AI ETF look-through is particularly valuable for passive investors holding multiple ETFs across brokers.
Frequently Asked Questions
Can I use both Curvo and DonkyCapital at the same time?
Yes — they solve different problems. You could invest via Curvo's managed account and also track other broker positions (DEGIRO, Trade Republic) in DonkyCapital. However, DonkyCapital cannot import data from Curvo/NANAK accounts directly.
Does DonkyCapital have a backtesting tool like Curvo?
Not currently. DonkyCapital focuses on live portfolio analytics for your actual holdings. Curvo's backtesting tool (track.curvo.eu) remains one of the best free tools for historical ETF return simulation in Europe.
Which brokers does DonkyCapital support?
DonkyCapital supports any broker that allows CSV export: DEGIRO, Scalable Capital, Trade Republic, Revolut, Interactive Brokers, Fineco, Lightyear and more. As long as you can export a transaction history CSV, you can import it into DonkyCapital.
Is Curvo available outside Belgium and the Netherlands?
Curvo's investment service (NANAK) is currently limited to Belgian and Dutch residents due to regulatory requirements. The free backtesting tool (track.curvo.eu) is available to everyone.
How does the 0.5% Curvo fee compare to self-managing?
On a €50,000 portfolio, 0.5% is €250/year. If you invest directly via a low-cost broker like DEGIRO with a broad ETF (e.g. VWCE at 0.22% TER), the total annual cost is typically much lower. DonkyCapital is free during Accesso gratuito, so the marginal cost of tracking your self-managed portfolio is zero.
Does DonkyCapital support ETF-only portfolios?
Yes — ETFs are the primary use case for most DonkyCapital users. The AI ETF look-through feature is specifically designed for passive investors who want to understand the real geographic and sector composition of their ETF holdings across all brokers.
