Make a list of risky assumptions. Sort by impact on being wrong about them. Now you have a list of the riskiest assumptions. Test those assumptions with experiments (google ads, landing pages, etc) that provide data. Set a bar for success. Run experiment. If results > success, move on to the next riskiest assumption. If results < success, form a new hypothesis, rinse, and repeat.
