On this week's episode of Bootstrapped, we talked with Aviva Goldfarb, founder of the Six O'Clock Scramble. This online meal planner offers busy parents health-conscious solutions for the daily scramble of cooking a family dinner. Aviva admits "my biggest competitor is free." Aviva monetized her idea through a membership model, offering dietitian-approved recipes that can be made quickly, along with a mobile grocery list. By requiring customers to submit a credit card to activate their free trial, Aviva has managed to gain a sizable following with a 60-70% customer retention rate.
