Eterny protects individuals’ financial lives – and gives the institutions that serve them the intelligence to protect and grow those relationships.
Why we built Eterny.
It started with a family reconstructing a financial life from paperwork – bank statements, a policy nobody knew about, a property valued a decade ago.
Nothing had been hidden. It had simply been scattered: across providers, across inboxes, across two decades of good intentions. Reassembling it took months, and the parts that were missed were missed for good.
That work should not have been necessary. The information existed, the tools to hold it existed, and still there was no single place where a household could see what it owned and hand that picture to the people who would need it.
So we built the layer that should have existed already – one private place that holds the picture, watches it for gaps, and opens to the people you choose at the moment they need it.
The stakes are only rising: the largest wealth transfer in history is being handled blind. Trillions will change hands over the next two decades, and most of it will move between people who have never seen the full picture of what is moving.
What we actually built.
Three parts, one picture – each usable on its own, compounding together.
The Vault
Encrypted storage for the documents and records of a financial life – readable by the household, not by Eterny.
The Engine
Extraction and analysis that turns those records into a live picture, and the picture into findings – gaps, risks and deadlines worth acting on.
The Layer for Institutions
The same engine deployed inside a bank's or insurer's own perimeter, on their own client data, feeding findings into their CRM.
How we decide, when it is not obvious.
Three rules we hold to when a shortcut would be easier.
01
Privacy is the product
Every design starts from what we can avoid reading. If a feature needs us to open your documents, the feature is wrong – not the constraint.
02
Quiet by default
We interrupt you when there is a decision to make and stay silent otherwise. An app that notifies you daily is one you stop reading.
03
Proof over promises
Certifications, press and customer quotes appear only once they can be evidenced. Until then the page says the slot is empty.
Who is building it.
We didn't design this from a whiteboard. We built it with notaries, lawyers and people who work inside banks and insurers, because getting this wrong costs families real money.
Jitka Paterová
Founder & CEO
Nobody can keep track of it all anymore. Your money sits with a dozen providers who each see one piece of it, and none of them sees the whole. That is how people end up paying for cover they don't have, missing a renewal that mattered, and leaving their family searching when something goes wrong. I built Eterny because none of that is anyone's fault, and all of it is fixable.
Dan Máslo
Co-founder & CPTO
Dan has spent eighteen years building products people use every day, and has taken several from an idea to a working business. He owns the vault and the engine: how your documents are stored, how they're protected, and how the system spots something worth telling you about. His rule is that privacy is a design input, never something we trade away for a feature.
