Storybook App is a consumer subscription app founded in 2018 by Francisco Cornejo and his co-founder (his wife), designed to help parents get young children to sleep through guided bedtime stories. The app is free to download with a seven-day trial, after which parents pay an annual subscription. The company is headquartered across a distributed team spanning Spain, Colombia, Argentina, Ecuador, and Australia. The company launched its MVP in mid-2018 on a pay-per-download model, generating roughly $90,000 in its first year. Revenue grew modestly to approximately $100,000 in 2019 before accelerating sharply to $400,000 in 2020, driven by paid acquisition on Facebook and Instagram. By November 2021, the company had surpassed $500,000 to $600,000 in revenue and was targeting $700,000 for the full year, supported by 1,500,000 all-time downloads and 10,000 active paying subscribers. Storybook raised a $1,000,000 SAFE round in 2020 at an $8,000,000 valuation cap, with participation from angel investor Jason Calacanis. The founding team retains a 50/50 equity split and was exploring a Series A of $5,000,000 to $7,000,000 at the time of the interview. The 20-person team was spending approximately $40,000 to $50,000 per month on paid social advertising while building toward a major partnership expected to deliver at least one million new downloads within its first 30 days.
