EstuaryBuilt by an architect, not a sales deck.
Estuary Logic grows out of hands-on practice: structuring real products, connecting real systems, and watching where complexity actually hurts inside an organization. The method exists because it had to work first, in engineering rooms, not slide decks.
An estuary is where a wide, undirected spread of water becomes structured, navigable flow. Note what does not happen: nothing is removed. The water is the same on both sides, it has been given banks. That is the honest version of what we do with complexity, whether it shows up in a product, a system landscape or a decision nobody can defend.

Estuary Logic exists because the same problem kept turning up in different clothes: a product line that had outgrown the way it was being described, and four systems each holding a slightly different version of it.
Talk to Jelle directlyThe problem is usually one layer down
A configuration issue is almost always a data structure issue wearing a different name. We go looking for the layer underneath before proposing anything at the layer you noticed.
It had to work before it was a method
Everything on this site started as something that had to hold up in an engineering room, with real part numbers and a real deadline. The framework came afterwards, which is the right order.
You should be able to check the work
Structure you cannot inspect is just someone else's opinion. Every model we build, and every answer an agent gives, traces back to the data and the rule it came from.
One person reads your message, and it is the one who would do the work.
That is the part a larger firm cannot copy. There is no account team between you and the person holding the model, no handover between the pitch and the delivery, and no incentive to find a bigger project than the one you actually have.
The fastest way to find out whether that is worth anything to you takes an hour and costs nothing.
