BUSINESS INSIDER - Julie Griggs and Danielle Dietzek, former healthcare professionals, founded the dating app Fourplay in 2019 with no prior tech experience. They left their jobs in 2022 to run the startup full-time. Fourplay, which facilitates double dates, faced early challenges, including COVID-19 and technical issues, but the founders overcame them by hiring in-house developers. The app gained traction through user-generated content, particularly a viral TikTok video, and now boasts 60K users. They credit their success to learning from mistakes, leveraging their network, and adapting to the tech space despite their initial inexperience.
