Plans

Decide the plan that fits your requirements

The same verified data on every plan, checked the same way, off one read-only brokerage connection — no credentials, and no ability to place trades. What changes is depth: performance alone, what you hold now, or everything you have ever held.

Prices are per connected brokerage account, billed monthly. Annual plans launching soon — two months free. The first writers are shaping this, so if something doesn't fit, say so on the call.

Plan one

Prove my track record

€39/month per connected account

Annual pricing (€390/year) launching soon

Prove the performance is real but reveal nothing about what you own. A private link, so you can post it on a public page to show performance.

  • ✓Verified returns — YTD, 1 year and 5 year — each beside the S&P 500
  • ✓Equity curve and Sharpe ratio, reconstructed as far back as your broker allows
  • ✓Investing style and median hold, taken from your own trades
  • ✓Asset, sector and country breakdown — equity, bonds, crypto, cash
  • ✓Portfolio size band, always shown — the exact figure only if you choose
  • ✓Deposits and withdrawals as a percentage, so returns can't be flattered by topping up
  • ✓Private link, rotatable any time — post it behind your paywall or wherever you like
  • ✓Page-visit metrics for every link, so you can see how many readers open your record
  • ✕No individual positions, anywhere

Getting started

Four simple steps to get started

Schedule a call

We check whether your brokerage connects at all and how far back its history reaches — before you commit to anything. It's also where you ask whatever you want about access, data, or leaving.

You provide the API connection

You authorise a read-only connection at your own broker. Portfolio summary only — no credentials reach us, and no permission to place a trade or move money exists in the connection.

We deliver your links

Two private, rotatable links, depending on your plan — one for performance, one for positions if you've chosen that. Built, verified, and syncing daily, with nothing for you to maintain.

The links live with you

Put them wherever you publish (Substack, X, LinkedIn). We run no leaderboard, no ranking and no directory of investors — your record belongs to you, and we have no opinion on how it compares to anyone else's. Every investor has their own niche: a trading style, an area of expertise, and their own way of talking to an audience.

Why we started

For most people, investing is the only realistic path to financial independence. Not a fast one. You put money aside every month, diligently and consistently, build your understanding of the market, and eventually the money does more work than you do.

Some learn from institutions, some on their own, some with the help of a consultant. With the internet, many have come to rely on independent financial writers: people who read the filings nobody else reads, sit on a position for three years, publish their reasoning in the open, and change their mind in public when the facts change. Over the last decade, an enormous amount of that work has been given away for the price of a newsletter, and a lot of people have meaningfully gained from it. That is a genuinely good thing that happened.

But the same openness that allowed those writers to reach an audience also allowed everyone else to reach those same readers. On a timeline, careful analysis and a cropped screenshot look identical. Some writers — knowingly or not — present an incomplete picture: cherry-picked trades, missing context, no sense of risk or drawdown. The cost isn't abstract; it's paid from someone's savings, by the person who could least afford to follow bad advice.

That is why we built TallyStick: to add a trust and verification layer for the writers doing the work properly. A place where performance can be checked, not just claimed.

This won't appeal to everyone, and it isn't meant to. Discord channels and alert services running on unverifiable confidence have no reason to want it — checking is the one thing their model can't survive. TallyStick is for writers whose record was already good before anyone asked to see it.

The call

Fifteen minutes, and no pitch

We're starting with a handful of investors, so this is as much your chance to shape it as mine to explain it. Half of the call is me checking whether your brokerage works at all — if it doesn't, I'll tell you rather than sell you something first.

What we cover

  • ✓Whether your broker connects, and how far back its history reaches
  • ✓What your record would actually show on day one
  • ✓Exactly what appears on your record, and what never will
  • ✓What it costs, and what you'd be committing to
  • ✓Anything you want to ask about access, data, or leaving
Book a 15-minute call

Let's get started

A few details so I understand what you're working with. The broker matters most — it decides what's technically possible — and the rest just means I come to the call prepared rather than asking you basics. It's also your chance to ask anything you want to understand better. If you would rather just email, I'm at verify@tallystick.tech.

I read every one of these myself. Expect a reply within two days.

Got it.

I'll be in touch within two days to book a time and discuss further.
