Scalable Capital
Europe's leading digital investment platform
scalable.capital ↗The average portfolio is shrinking from €33K to €30K. Scalable must solve two problems at once: retain sophisticated users AND grow smaller accounts into bigger ones. If they don't, they become a starter broker people outgrow.
Growth comparison · 2022–2024
Avg portfolio
The average account is shrinking even as sign-ups accelerate.
Scalable is growing users faster than assets. Every new user brings less money on average.
Three recommendations, in order
| Opportunity | Impact | Complexity | Timeline | Priority |
|---|---|---|---|---|
| Weekly Savings Plans | High | Low | 4–6 weeks | Start now |
| Portfolio Visualization Suite | High | Medium | 8–12 weeks | Plan now |
| Graduated Investment Paths | Very High | High | 12–18 months | Next quarter |
Weekly Savings Plans
The problem: Weekly DCA is the one of the most popular savings cadence among younger investors as well as in the USA, but Scalable only offers monthly. It's one of the most user-requested feature on Reddit.
The opportunity: Every savings plan execution creates an engagement touchpoint — a notification, an app open, a portfolio check. Monthly plans generate 12 of these per year. Weekly plans generate 52. This is 4× the habit reinforcement. And the backend already supports flexible schedules. This is a frontend and scheduling change, not a platform rebuild.
Neither Trade Republic, Revolut, nor N26 currently offer weekly savings plan execution. Shipping first is a meaningful differentiator for the DCA-native cohort.

proposed
Weekly savings plans create 4× more monthly habit-reinforcement touchpoints than monthly plans.
Weekly execution multiplies infrastructure load. Validate with a 10% rollout and monitor for payment failure rate spikes before full release.
Portfolio Visualization Suite
The problem: Scalable's portfolio view is a plain text list which lists stock names and percentage returns, nothing more. No allocation pie chart. No benchmark overlay. No XIRR. Users need to export their data to Portseido, Portfolio Performance, and Excel to get the analysis they want.
The opportunity: Gate advanced visualization behind PRIME+. FREE users get allocation chart + basic benchmark overlay which is enough to be useful. PRIME+ users get XIRR, custom benchmarks, correlation matrix, tax-adjusted performance views which is enough to make PRIME+ feel worth €4.99. The BlackRock analytics partnership already exists; the frontend just isn't surfacing it.
I use Scalable personally. This is the feature I miss most. It's what keeps me considering IBKR.
Portfolio view — before & after
Before — text-only list
After — visualization suite
Current: a plain text list with no visual context. Proposed: allocation donut, benchmark overlay, and a portfolio health score.
IBKR's analytics are comprehensive and free. The goal is to make Scalable better so power users don't feel the need to switch.
Graduated Investment Paths
The problem: Users start at €25/month, grow their portfolios over years, and eventually outgrow what Scalable offers. There are no lifecycle nudges, no milestone celebrations, no signals that Scalable sees them as a long-term investor rather than a sign-up. The product today treats a student with €500 and a professional with €50,000 identically.
The opportunity: Build a graduated lifecycle that grows with the user. Phase 1 (quick): milestone celebrations and tier-awareness nudges. Phase 2 (medium): alternative investments via partnerships like private equity, alternative investments, real estate, private credit. Phase 3 (long): Wealth+ tier for €250K+ portfolios with access to a human advisor.
The robo-advisor (Wealth) is already Scalable's unique moat. Extending upward to Wealth+ deepens that moat and adds the highest-LTV user segment in retail finance.
Full investor lifecycle — proposed
Each tier maps to a real product. The gap today: no lifecycle nudges or graduation paths between tiers.
Alternative investments require regulatory clearance (MiFID II, PRIIP KIDs). Phase 2 timeline is dependent on partnership and compliance work. Legal review can be started in parallel with Phase 1.
Competitive Landscape
The German retail investing market is effectively a two-horse race between Scalable and Trade Republic, with Revolut and IBKR as flanking threats. Scalable's position which is to sophisticated but accessible with a strong robo-advisor is a strong moat. But Trade Republic is closing the UX simplicity gap, and power users eventually graduate to IBKR when they hit the analytics ceiling.
Competitive positioning
Scalable owns the "sophisticated but accessible" quadrant. Trade Republic is simpler; IBKR is more powerful. That gap is the moat — and the risk.
| Scalable | Trade Republic | Revolut | IBKR | |
|---|---|---|---|---|
| Robo-Advisor | ✓ Full Wealth product | ✗ None | ✗ None | ✗ None |
| Analytics | Strong (BlackRock) | Basic charts | Basic | Advanced (complex) |
| German Tax | Auto + optimised | Auto-withholding | Manual | Generic reports |
| Savings Plans | Best flexibility | Good, less flexible | Basic recurring | None |
| UX simplicity | ★★★★★ | ★★★★★ | ★★★★ | ★★ |

Higher 90-day retention in weekly cohort; NPS delta
PRIME+ upgrades are 60% fee-driven, 40% feature-driven
User interviews + upgrade funnel analysis (upgrade reason survey)
Informs whether to lead pricing or features in upgrade prompts
YouTube/blog CAC is less than 50% of paid ad CAC
10× content production velocity over one quarter; measure attributed sign-ups
If true, reallocate acquisition budget toward content-led growth
North Star Metric
North Star
Active Investors
Users with ≥1 active savings plan OR ≥1 trade in the last 30 days. This filters out dormant accounts and captures both passive savers and active traders.
A Note on the Research
I've been a Scalable Capital customer for 3+ years. I started with a €25/month MSCI World savings plan as an Indian student in Germany and had to visit a post office for ID verification because my passport wasn't supported for digital KYC. That week of friction versus the same-day experience for German ID holders is a real barrier to international users.
Today I run multiple savings plans and check the app 1–2× a week. Scalable Capital taught me financial discipline and the value of consistent investing. I'm still on Scalable precisely because the habit is built in. What I'm missing is the visualization layer. That's the feature that would make me stop thinking about IBKR.
Why this matters: My journey from €25/month beginner to feature-hungry power user mirrors exactly the lifecycle challenge this teardown is trying to solve.
Methodology — 3+ years personal usage, firsthand workflow documentation, competitive analysis across Trade Republic, Revolut, IBKR, and N26. Public data sources: press releases, app store reviews, r/Finanzen, industry reports, and Scalable's own documentation. No internal data or employee interviews were used. All opinions are my own.
