Craft Clubs, a UK-based booze subscription service, appeared on the British version of Shark Tank in 2016 and secured a £75,000 investment, nearly doubling their six-month business in just two months, thanks to their existing software tools such as MoonClerk, Zapier, and Google Sheets. The company's founders, Jon Hulme and John Burke, built a customized system using these off-the-shelf tools, automating workflows with Zaps, which allowed them to scale efficiently without hiring additional IT staff. Their use of Zapier enabled them to create complex integrations, such as adding new customer data to Help Scout and MailChimp, and experiment with new workflows without incurring significant costs. The company's success showcases the potential of using automation tools like Zapier to drive business growth.
