Editorial standards.
The rules below are the ones we work to internally. We publish them so that when something on the site doesn’t match them you can call it out — that’s how this stays honest.
Every number, name, and dollar figure on this site comes from a filing on the public record — SEC EDGAR or the U.S. House and Senate financial-disclosure systems. We do not buy data from alternative providers and we do not show derived figures that can’t be tied back to a specific document.
If a value would require us to invent or guess, we mark it data-pending and explain the gap. We’d rather show you nothing than show you a fabricated number.
The Filing Post is editorial intelligence. We aggregate filings, dedupe them, frame what they show, and surface patterns where the data supports them. We do not recommend, advise on, or solicit any securities transaction. Nothing on this site is investment advice. Nothing here is a recommendation to buy, hold, or sell.
The Morning Brief and the Convergence Cards summarise what filers have disclosed. They do not predict what those filings mean for prices, and we will not write copy that implies they do.
We have no commercial relationship with any filer covered on The Filing Post. We don’t accept payment, placement, or comp from any fund, advisor, broker, or member of Congress. The editorial list of “experts we’re reading” reflects internal judgement about who’s worth following — nothing on that list is sold.
Mathonyx GmbH, the operating entity, is part of the Lorenz Gruppe family investment office. The Lorenz Gruppe’s own trading activity does not influence what appears on this site, and Mathonyx does not share user-level data with any other entity in the group.
Three editorial streams are generated by Anthropic’s Claude against public-record SEC and Congressional filing data: the Daily Brief (06:30 ET, weekdays), the Manager Deep-Dives (Sunday 09:00 ET, one per week from the Top-Performer cohort), and the Filing-Commentaries (continuous, triggered by Form 4 ≥ $10M / STOCK Act ≥ $500K / 13D/G filings / large 13F position changes). Each piece is written by Claude Sonnet 4.6, then voice-reviewed by a separate Haiku 4.5 reviewer against a public scoring rubric. Pieces below the publish threshold are regenerated up to three times; otherwise they’re discarded. Cost is tracked per piece.
The model never writes numbers it didn’t read from the data. Every factual claim traces to a specific row in the citation corpus we pass in. Hallucination of dollar amounts, position counts, or filer identities is caught by a validator step that rejects citations to non-existent rows.
Static page copy (this page, About, Methodology, plan descriptions, the legal pages) is human-written. The AI writes editorial against data; the humans write the framing.
Our masthead motto, lifted from the Royal Society in 1660, is Nullius in verba — take no one’s word for it. It appears at the foot of every email we send and on every page on this site. It is also the operating rule: when something on The Filing Post conflicts with the underlying public filing, the filing wins.
If you see something on The Filing Post that doesn’t match the underlying filing, write to hello@thefilingpost.com. We fix data defects in place and acknowledge structural ones in the relevant page’s data-pending notice. We don’t silently re-write history.
