What if you could test a decision before you make it?

Run the decision before you make it.

Test a decision against ten thousand simulated futures — across fifteen domains, from ICU capacity to supply chains to portfolios. Every public run is replayable, its assumptions visible, and graded against what actually happened.

If the carrier suspension on the Asia–EU lane holds six weeks, retail lead times breach SLA in 62% of runs

Median delay +9.4 days (CI 7.1–12.8). The largest driver is tier-2 supplier rerouting capacity, not port congestion. All assumptions are visible in the run.

Track record: every public prediction is graded when reality arrives — including the misses, with post-mortems. The calibration score is published and updated after each grading.

Two ways in

Make a decision

Browse runs in your domain, read the findings, fork the assumptions, and run your own scenario. If a consultant sent you a verified finding, the replay link shows you everything they saw.

Run decisions for clients

Put a verified, replayable simulation behind every recommendation. The mark certifies the math; your assumptions stay yours — and stay visible. Findings your client can try to break, and can't.

What this is

An observatory, not an oracle

Decision Observatory is a simulation instrument. Describe a decision, and the engine runs thousands of parallel futures — each with different sampled inputs — and reports the distribution of outcomes: the median, the tails, the confidence intervals, and which assumption moves the result most.

It does not predict the future. It quantifies exactly how uncertain the future is, given what you believe today — and it publishes its own grades so you can judge how well-calibrated those quantifications have been. We don't ask you to trust us. We show you the record.

Before launch

Join the waitlist

The observatory opens with its first live, graded runs. Leave your email and you'll get two things: a note when the instrument opens, and first claim on one of the 100 founding-member seats at $99/month, locked for life. Nothing else — no newsletter.
