Aetherya is the computational strategy firm. We simulate how a market responds to each option, recommend the move, and measure the call against what happens. Thesia, built by Aetherya, is the self-serve product for founders, small teams and agencies.
This is the 2nd launch from Aetherya. View more

Hi Product Hunt. I'm Andrei, founder of Aetherya, writing from Bucharest.
Most decisions get tested on the people who have to live with them. A price goes up, a headline ships, a cold email goes out, and the data arrives after the damage.
Thesia is our attempt to move that test earlier. You describe the decision, or paste a page or an ad, and Thesia simulates the people it is meant for. Each one decides for their own reasons, so you see where they hesitate, object and leave.
The example in the gallery is a price test. "Should Pro go from €29 to €39?" comes back with the share who stay, a likely range, and a crowd of dots you can open one at a time. Open Luca, a student, and you see what he said ("I'd have to think about it") next to what he thought ("I'm gone the day this renews"). That gap is why we built a population of people who each have reasons of their own.
Then you change one thing and ask the same audience again. In the example, a €19 student plan keeps 90% of people instead of 81%, but revenue rises 4% where the plain price rise gave 9%. Thesia does not choose for you. It shows you the trade.
Everything in the gallery and the film is example data, recorded from the real app and labelled that way.
The Free plan gives you 100 instant reads and one full simulation a month. Every plan runs on the same model, Myrias, our own cognition model.
I'll be here all day. What decision would you run first?
