Decision rehearsal software

Rehearse business decisions before they become expensive.

Describe the decision and the evidence you have. B4Math maps likely customer reactions, exposes weak assumptions, and returns a decision memo with the next test that could change the recommendation.

Conversion loss offsets expansion and sales must retreat to the old anchor.

How it works

A visible chain from evidence to action.

The workflow keeps facts, assumptions, modeled reactions, and recommendations separate so a team can challenge the result instead of accepting a black box.

  1. 01

    Frame the decision

    Confirm the proposed change, audience, goal, constraints, horizon, and success metric.

    Structured input
  2. 02

    Audit the evidence

    Separate user-supplied facts, imported signals, model assumptions, and missing information.

    Assumption ledger
  3. 03

    Stress-test reactions

    Compare segment responses and scenario ranges while changing the assumptions that matter most.

    Sensitivity analysis
  4. 04

    Choose the next move

    Read the recommendation, downside, reversal condition, rollout, stop rule, and cheapest next test.

Use cases

Use it where learning after launch costs too much.

Explore every use case
Transparent assumptions

See which beliefs are carrying the recommendation.

Every important claim has an origin, confidence level, likely impact, and sensitivity flag. Missing evidence stays visible.

Sensitivity preview

Move an assumption. Watch the decision move.

Updated viable-outcome range56-72%

The recommendation remains a conditional go. Value proof is still the decision-critical assumption.

Scenario comparison

A range only matters when its conditions are visible.

B4Math shows the trigger, likely customer response, business effect, uncertainty range, and mitigation for each branch.

Example recommendation

The conclusion reads like a decision, not a dashboard.

Editorial emphasis is reserved for the recommendation. Operational details remain compact and easy to challenge.

Directional evidence
Conditional go

Pilot the $129 anchor with new annual-plan buyers before changing public pricing.

The price has credible upside in the ROI-led segment, but the evidence does not support a broad public change yet.

Strongest support
Annual-plan buyers already frame the product against avoided launch and research cost.
Main downside
Value proof is weaker than the size of the price increase.
Recommendation changes if
Hold the price if fewer than 5 of 15 qualified buyers accept the annual anchor.
Missing evidence
Observed willingness to pay at $129 and renewal response from protected cohorts.
Next cheapest test
15 buyer conversations and 5 written annual-plan commitments.
Stop condition
Stop after 15 qualified conversations if acceptance stays below five commitments.
Suggested rollout

Offer the new anchor to net-new annual buyers, preserve existing contracts, and review conversion, sales-cycle length, and objection mix after 30 days.
