Henselian lets insurers, banks and energy companies ask "what if?" a thousand times over and get answers in seconds. It runs on your own servers, so your data never leaves the building.

Why it matters
Every risk team has a list of what-ifs that were too slow or too costly to run. When asking costs too much, you stop asking. Henselian makes the next question cheap, so you can look at more of the futures that matter, not fewer.

The same simulations your team already trusts, run on a graphics card instead of a queue. What took an afternoon now takes a cup of coffee.

The app
A calm desktop app for the people who make the call. Pick a model, change an assumption, and watch what moves.
Tour the appThe receipt
The data, the assumptions, the steps and who signed off, kept on a record that cannot quietly change. Your auditor can run it again and get the same answer.
How it stays honestReceipt
Runs again, same answer
The answer is never one future. It is all of them, at the scale your business really runs.
Insurance
2.5 million members × 600,000 possible futures × a lifetime each
1.5 trillion lives, priced in 41 seconds.
Every member of a pension scheme, valued on every future, before the price is quoted. Not a sample. Not a shortcut. All of them.
Henselian for insuranceBanking
Every loan and deposit × every quarter × thousands of rate paths
Every position, lived through thousands of futures.
Not an average customer in an average year. Each position, revalued in each future, so the risk you report is the risk you hold.
Henselian for bankingEnergy
365 delivery days × the wind on each one × every price path
365 days, lived before you commit to one.
Supply, price and weather moving together, day by day, so a hedge is tested against the bad months before it is signed.
Henselian for energyMeasured, not promised
Measured on one RTX 4090 workstation. Every source is on the research page.
Check the numbersSovereign by design
Henselian is installed where your data already lives. We never see it, and nothing needs the internet to work. You decide who runs what, and when.
How we start
Someone who builds the engine reads what you wrote, then calls you to ask what we need to know.
We rebuild your question on a made-up book shaped like yours, so no data has to leave your hands.
At full size, in front of you, changing it while you watch. Then you decide whether to run it on your own data.
No. Henselian runs on your servers, so your data stays with you. We have no way in unless you invite us, and then only for the time and the task you agree to.
No. We start from a question you already answer today and run it beside your current model, so you can compare the two, number by number, before anything changes.
Yes. Everything it needs, including the assistant, is installed on your machines, and it works fully on a network cut off from the internet.
They open its receipt: the data, the assumptions, the steps and who approved it. They can run it again and get the same answer.
One question that takes too long today. We model it on a synthetic book shaped like yours, run it with you at full size, and you decide what happens next.
Before the storm
Not the one you calculated and got wrong. The one that was too slow, too costly, or too late to ask. Henselian gives you the time back.
Bring us the simulation your organisation wishes it could run faster. We will show you what is possible, on a book shaped like yours.
