A data foundation that brings accounts, portfolios and total wealth together.

This makes your investment strategy verifiable against the real portfolio every day. “Does my portfolio still fit my plan?”

[Why Investboard exists](/en/warum-investboard)

## The costliest gap in your portfolio is behavior.

The panic sale. The rebalancing that never happened. The single bet that grew into your largest position.

Investboard brings strategy, portfolio analysis and behavioral data into a system that shows how well you are following your plan every day.

## Your investment mandate. Written by you, in plain language.

Choose an investment philosophy, define target zones and record your own rules for risk, rebalancing and turbulent markets. Dated, understandable and verifiable.

Investment mandate · June 12, 2026 · Illustrative · sample data

### Philosophy

Long-term wealth building through index funds, globally diversified, reinvested automatically. No single holding above 5% of the portfolio.

### Allocation

Equities 55–65%. Bonds 20–30%. Cash 5–15%. Alternatives 3–8%.

### Rebalancing

Twice a year, or when allocation leaves its 5-percentage-point drift band.

### Behavioral rule

No strategy change in weeks with more than 5% market movement.

Signed by you, to your future self.

## One number that greets you honestly, every day.

Plan alignment: 94 out of 100. The score combines allocation, target bands and mandate rules into one clear answer: how close is your portfolio to your plan today?

Plan alignment · Illustrative · sample data

- Days on plan: 312 (since signing the mandate)
- Drift: 0.8 pp (within every zone)
- Next rebalancing: Sept (on schedule)
- Cost of tinkering: −€650 (over the last 365 days)

## In the worst moment, you hear your own voice.

Investboard brings your own rules back into view at the right moment and makes every decision verifiable against your personal plan.

## Discipline becomes measurable, when rules become a system.

### Cooling-off

A deliberate pause before any strategy change.

A cooling-off period you set brings long-term rules back into the decision process.

### Cost of tinkering

The behavior gap, in euros.

Investboard calculates how departures from your own plan affected the result.

### Annual review

An honest yearly letter to yourself.

What you set out to do. What you kept. What surprised you.

## Detects what has changed relative to your plan. Then explains what it means.

Notes arise from your mandate, your portfolio data and relevant changes.

Illustrative · sample data

### Drift: Equity weight has left the drift band.

Currently 67%, above your band of 55–65%. A rebalancing would be on schedule.

### Tax opportunity: Loss harvesting possible before year-end.

Two positions could realise around €840 in tax savings, within your mandate.

### Calm: Your plan is on track.

Within every zone for 41 days. Plan alignment remains stable.

## Mandate, portfolio and behavior. Connected in one system.

Investboard connects your mandate to your actual holdings, looks through funds and risk, and measures every deviation against the same standard: your personal investment plan.

What the product shows: How your mandate becomes the standard for your whole portfolio.

### Product · Portfolio dossier: One wealth file. Coherent from end to end.

One mandate · the same holdings · the same data foundation

Explore Investboard through one coherent sample file. Its mandate, portfolio and signals all build on the same holdings and the same data foundation.

### Three layers. Your own standard.

### 01 · The mandate: The plan is set before pressure builds.

Goals, corridors and a cooling-off period are recorded before market moves provoke a reaction.

### 02 · The portfolio: See what you actually own.

Portfolios are brought together, funds opened up and deviations checked against your mandate.

### 03 · The context: Every deviation explained with evidence.

Every signal names its reason, evidence and meaning and connects the finding to your personal investment plan.

- Connect: Accounts, portfolios and assets in one complete wealth picture.
- Check: Allocation, concentration and behavior are checked against your mandate.
- Interpret: Material deviations with the numbers that caused them and what they mean.

Investboard provides context. You decide.
