WALDHORN.AI is where the paperwork of a music career lives.

The same document confuses everybody it touches.

If you write, produce, manage, book, publish or run a label, your career rests on agreements you signed faster than you read them. The writer and the composer, the producer and the independent artist, and just as much the manager, the agent, the publisher and the label owner across the table from them. Different seats. The same sentence, when it goes wrong.

I have sat in most of those seats.

Sixteen years in classical music, twelve of them in a symphonic orchestra. Twenty years producing records. Festival stages as a DJ somewhere in between, about as far from an orchestra pit as one industry reaches.

None of it taught me anything about a contract.

So I signed bad ones. Some of my own recordings are signed away in perpetuity. That word does all the work: there is no date on which they come back, because nobody ever wrote one down. I will not get those masters back.

Signing was only the first way to lose money. I could not tell whether a royalty was missing, let alone how to chase it. Deadlines sat in my inbox until they had passed, and an option that lapses quietly is worth exactly as much as one you were never offered. When a deal needed renegotiating I did not know what was normal to ask for, so mostly I did not ask.

Every one of those is a feature now.

That was never a product strategy. They are the holes I fell through, in the order I fell through them.

The explanation came later, from the side that sends contracts rather than signs them. Managing artists. Running a label while consulting for a division of a major label group, which meant hearing the independent side and the major side of the same argument in the same week. That is where the paperwork finally made sense to me, years after it could have helped.

For the sixteen years since, I have read other people’s deals. Hundreds of artists, from a lot of countries, arriving with the same handful of clauses and nearly the same sentence:

I signed it, I did not really understand it, and now this is happening.

You can only hear that so many times before you build the thing that would have helped.

A contract reader tells you what a document says and then leaves.

A new one launches every week, and each of them stops where the risk begins. A music agreement keeps working for decades after anyone last read it. It decides who owns the masters, when an option can be exercised, when rights come home, and what every royalty statement should say.

So WALDHORN.AI starts where the others stop. It drafts the next agreement, carries the redlines and the approvals, and seals the executed version with its own fingerprint, so anyone can verify it years from now. Then it keeps what the deal created: the rights and the splits, the registrations, the deadlines the contract quietly set, and every royalty statement, checked line by line against the terms that were actually signed.

Reading is a moment. The record lasts as long as the contract does.

The people who built it with me took longer to find than the software did.

Music attorneys, managers, artists and agents, gathered over those sixteen years. They did not endorse this product; they shaped it. They are why it can tell a reversion clause that will actually trigger from one written so it never will, and which costs in a recoupment schedule are normal and which are somebody quietly moving their own marketing spend onto your account. That knowledge is not on the internet. It lives in people who have argued the same clause four hundred times.

It was also built on the assumption that it can be wrong, which is rarer in this field than it should be. Automated judgement of whether a clause is fair is still wrong often enough to matter, so a separate layer sits between the model and anything you are shown. It checks that a quoted clause is really in your document, and that every figure follows from the ledger it came from. There is an engine that grades how fair a whole deal is. It has never been switched on, because its first live judgement was wrong, and a confident accusation against an innocent counterparty is the worst thing this product could do.

The company carries my surname. When it tells you a clause is safe, a person is answerable for that.

My recordings are not coming back.

That was settled long ago.

What still gets me is that the sentence has not changed. People arrive saying I signed it, I did not really understand it, and now this is happening, and they are saying it about contracts signed this year.

So: a rights operating system for the music business. A dry name, and the accurate one. Every deal, right, split, deadline and proof, held in one record that answers to you rather than to the other side of the table.

It is the thing I did not have. Signing takes an afternoon. Living with what you signed takes the rest of your career, and you should not have to do that from memory.
