Test a product choice before launch

Your next product decision has two futures.

Test two product choices with the same simulated buyers. Measure how behavior changes and how certain the estimate is.

The evidence gap

Most teams learn the answer after the decision is expensive.

Past data explains what happened. Product teams still need to know what might happen under another choice.

After the choice

Analytics

What happened?

Shows what happened after launch. It cannot compare the option you did not choose.

Before the choice

Interviews

What do people say?

Explains what people say before launch. Stated intent can differ from behavior.

Before the choice

Causl

What changes behavior?

Runs both options as a controlled experiment before the team locks the offer.

How the experiment works

Compare one product change with the current offer.

Causl tests the same simulated buyers under two offers. Every other part of the simulation stays the same, which isolates the effect of the offer change.

Validation against published research

The engine is tested against human experiments.

The behavioral engine behind Causl has been tested on 43 design-filtered human-study replications across 9 domains. A score of 1 would mean the engine ranked every choice in the same order as people. Failures are included in the public record.

From experiment to decision

See the whole system before you change it.

Causl turns one product question into a shared decision model. Your team can review the evidence together.

01

Model the decision

Connect the product change to the outcome your team cares about.

02

Compare the options

Compare the current path with one controlled change across the same simulated market.

03

See what changes

See how buyer behavior changes and how certain the estimate is.

04

Keep the evidence

Record the question and result with the decision they support.
