## Summary

Loren Castle, founder of Sweet Loren’s, explains how she transformed a small regional cookie dough business into a national brand sold in over 30,000 stores by listening to customer feedback and pivoting to an entirely allergen-free product line. She details the difficult recipe development process, involving extensive testing of potato and tapioca starches to replace eggs and dairy without compromising taste, and her strategic decision to discontinue her original product line to focus on this high-demand niche. Castle also discusses her early struggles with manufacturing, including being forced out of a co-packer, and her deliberate choice to grow slowly to achieve profitability before scaling nationally into major retailers like Kroger and Publix.
