Early access

Know what you own, why you own it, and what you plan to do.

Foliotron brings your portfolio, research, decisions, assumptions and reminders together, so the context behind your investments stays with your portfolio.

For individual investors who make their own decisions, hold more than one investment or broker, and want their research next to their portfolio rather than somewhere else.

Heineken is a global brand with distribution scale and margins that let it set its own prices. A quality core holding with a long horizon, not a cyclical catch-up trade.

Heineken holds its European volume against cheaper own-label beers.

Your portfolio, with your reasoning attached

Twelve real screens from the app, no mockups. Grouped by where you actually work.

Portfolio cockpit1 / 12

The whole portfolio in one line: every asset you own, over the last 30 days.

One number for what the portfolio did over the window you choose.

Dividends coming up and research still open, on the same screen.

  • Know why you own it

    Record why you own each investment, what needs to stay true and what would change your mind. Your investment case stays understandable over time.

  • Remember what you researched

    Keep notes, sources and insights with your investments. Easily find out later why you once reached a conclusion.

  • See what your investments are really doing

    Compare your portfolio with your own benchmark and see where your risk really comes from. Including sectors, regions and overlap between funds.

  • See what income is coming

    Track dividends and other payouts and see what is coming up. Deposits, withdrawals and costs are included in your cash overview too.

  • Bring in your portfolio without retyping

    Import transactions from supported brokers and exchanges or connect them directly. Manual entry always remains available.

  • Keep your financial data private

    Sensitive data is encrypted with your own key. Without your access, amounts, notes and strategies cannot be read.

Why I built this

I built Foliotron because I kept missing the same thing in broker apps and spreadsheets: context.

Broker apps are good at showing prices. Spreadsheets are flexible, but they quickly become fragile. What I wanted was a place where performance, notes, decisions, assumptions and review moments live together.

I use Foliotron for my portfolios. To see what the trading day has brought, to keep track of research, and to check whether my investments still fit my goals and strategy. That way, I not only know what is happening, but also where I may need to adjust. It gives me overview and control.

Foliotron is now concrete enough to test with people outside my own portfolio.

I am looking for a small group of individual investors who want to try Foliotron and give honest feedback. Not for a mass launch yet, but to learn whether this solves a real problem for people who actively manage their own investments.

I am looking for a small group of individual investors who want to use Foliotron first and tell me what works, what is unclear and what is missing.

What does it cost?
Nothing during early access. After that Foliotron becomes a paid subscription. What it will cost I decide together with the first users.
What happens after I sign up?
I read every signup myself and invite people in small groups, so I have time for questions and feedback. You get a personal email when it is your turn. Foliotron runs in your browser, so there is nothing to install.
Does it work with my broker?
Foliotron recognises transaction files from DEGIRO, Saxo and Trade Republic on its own; for any other broker you point out the columns once. Bitstamp, Kraken, Bitfinex, Bitvavo, Iconomi and eToro connect with a read-only key, and manual entry is always there. Broker not listed? Name it in the form, that decides what I support next.
