Assumptions
Name the claim, consequence, owner, and evidence needed to change confidence.
For founders
Know the next decision your evidence can support.
Turn assumptions into threshold-based experiments, preserve what you learned, and keep every next action connected to its source.
What changes
Stop reconstructing the truth from fragmented activity.
Generic checklists hide the venture's actual risk.
Experiment results disappear into decks and notes.
Advice arrives without a durable decision record.
What becomes visible
One highest-leverage next action with a reason
Critical assumptions ranked by risk and evidence strength
Experiments with thresholds defined before results
Mentor decisions linked to follow-up work
Inside the workspace
One evidence record, shaped for the work of the role.
Experiments
Define method, sample, threshold, and deadline before collecting outcomes.
Decision log
Record what changed, why, who decided, and what happens next.
