About
You can do the work. Nobody can stay awake for it.
Buying a company well takes an evening. Owning it well takes every quarter after that, and that is the part nobody sells you.

The problem
A decision is a moment. The reasons are perishable.
You read the accounts. You worked out what the business earns on its capital, what you were paying, and what had to stay true for that price to make sense. That evening you knew more about the company than almost anyone who owned it.
Then the evening ended, and the company kept filing.
Margins move. Debt is added. An auditor resigns on a Tuesday in February. All of it is public, dated and free, and all of it arrives while you are doing the job that pays you. It is not a knowledge problem. It is that conviction quietly becomes memory, and a memory cannot be checked.
Why nothing fixes it
Noise is not vigilance.
I built Ninety Nine, a securities services provider, and sold it to a tier-one global bank, then ran operations and internationalization at Alpaca, the brokerage API behind hundreds of fintech apps. Order flow is honest in a way surveys are not.
Almost everything built for investors is built to be opened: prices flashing, an alert on every move, a stranger with a view to sell. None of it guards the reasoning. An alert that fires on everything is indistinguishable from one that fires on nothing, and within a fortnight both are muted.
The refusals
One job, and the rest refused in writing.
A tool that does everything guards nothing, so what this one will not do is written down rather than left open. No tips. No portfolio to copy. No assistant answering for the accounts.
They are on the pricing page, in the methodology, and in the product itself. They are what I would read first if I were you.
What we do
Discover companies, research each one to its filings, track what matters, and take your work into your own spreadsheet.
Find the companies that pass your tests. Read one against its peers and its own filed years before you buy. Run what you own as one portfolio.
Then write down why you own each one and the numbers that must stay true. Every night they are re-tested wherever we hold the figure. A filing is picked up the night after it is published. The first night one breaks, one email arrives, with the arithmetic and the filing. Never a second about the same break.
ValueScreener shortens the arithmetic, never the judgment: whether to own a company stays yours.
What we believe
Five commitments, each with the mechanism that keeps it.
A value anyone can write on a page is worth nothing. Each of these is enforced in the product and checkable by you.
- 01Numbers are sacred.A figure we cannot source reads n/a. Never zero, never an estimate wearing a decimal point.
- 02You are the analyst.No buy, hold or sell of ours, no verdict word, and no fair value or price target of ours on a company. Where we publish a score or a ranked list, its method is published with it.
- 03Silence is a term.Most nights nothing breaks and you hear nothing. Every pass that finished is counted anyway, with what each guardrail last read.
- 04The method is published.Every weight, threshold and refusal rule is readable before you pay, not after.
- 05Plain prices.One list price per plan. No launch rate, and no discount offered on the way out: a price that drops when you threaten to leave was never the price.
Who this is for
You hold five to fifteen companies, chose every one yourself, and can still defend the reasoning. You have a demanding job that is not this. And you once found out late about something you would have wanted to know the week it was filed.
Who this is not for
Traders. Anyone looking for a tip, a signal or a model portfolio. Anyone who wants the software to hold the opinion: we do not have one, may not sell one, and will not perform one.
