When Zoë Foster Blake gets frustrated by a problem, she creates the solution. Struggling to rein in emotions during a bad breakup? She made an app for that. Looking for a flatulence-based narrative to read to your child? She wrote it. Trying to find skin care products that are simple and natural, but not obnoxious? She has made them, too.

Go-To is her new focus, a business she never thought she would start but one that has been a runaway hit in Australia and has expanded into the United States. Recently, motivated by her search for gentle natural products that worked on her two young children, Ms. Foster Blake began the offshoot line of children’s products Gro-To.
