Stress-test the future
before you ship the decision.

Brox simulations let you stack scenarios that haven't happened yet, across thousands of real-human digital twins, and get probability-weighted outcomes in 24 to 72 hours. Not 6 months. Not $500K.

Some of the things you can simulate

Stack any of these. Or all of them.

Crisis cascade simulation

5-stage news cycles over 168 simulated hours, with parallel social-media amplification waves. Used by brand teams, comms teams, and bank risk teams.

Stress testing & scenario simulation

Liquidity squeezes, AI trading losses, cyber attacks, regulatory shocks, geopolitical shifts. We've run these for 5 major US banks.

Monte Carlo scenario analysis

1,000+ probabilistic simulations across compound variable combinations. Probability-weighted outcome ranges, confidence intervals, tail-risk identification.

M&A commercial diligence

Replace analyst-assumption default curves with twin-derived behavioural distributions. We did this for a multi-billion-dollar oncology deal. The thesis didn't clear.

Drug launch & adoption simulation

Patient awareness, HCP prescribing, copay sensitivity, side-effect resistance. Ran 528+ twins on GLP-1 adoption: 73.6% said "I don't need it." Cost was the barrier 4.6% of the time.

Borrower behaviour & default modelling

Strategic default rates, payment prioritisation, switching behaviour under stress. Validated within 0.4 percentage points against the Federal Reserve's prediction.

Four steps. Same shape every time.

How a simulation gets built

  1. Define the scenario

    What's the question, the variables, the segments?
    We help you scope.

  2. Map to the right panel

    Existing twins for most categories.
    Custom recruitment if you need niche or B2B specialists.

  3. Run the stack

    Stack scenarios together. Run a thousand at once.
    Weighted, probabilistic, traceable.

  4. Get the dashboard

    Interactive output. Confidence intervals.
    Reasoning per outcome. Click to source.

We could write pages and pages of marketing and sales fluff but instead we'd prefer just to show you the product.

Schedule a demo

Contact us and we'll set up a call, during that call you should come prepared with some business and research requests and we'll go through them together live. We'll also explain how we build our digital twins, why you can trust them, how to deploy them, how much it costs (it's a lot), how we validate them and anything else you fancy talking about. You'll see ROI immediately.

Currently live in the US, UK, Japan and Turkey and launching in much of the Middle East and APAC pretty soon.
