The path to Klaviyo’s growth is firmly grounded in its bootstrapped beginnings. Co-founders Andrew Bialecki and Ed Hallen shared an entrepreneurial drive and a desire to build a durable growth business – one that could help other entrepreneurs succeed. They founded Klaviyo in 2012 and bootstrapped the business for three years, writing every line of code, connecting with customers on a daily basis and constantly experimenting to ensure product-market fit. This relentless focus on customer and product helped Klaviyo hone-in on its north star metric: sales their customers created with Klaviyo, what the pair called “owned revenue.” Summit’s partnership with Klaviyo began in early 2019, and the company has since scaled to serve more than 60,000 businesses worldwide, delivering more than 100% customer growth in 2020 and helping to drive billions of dollars in owned revenue for brands large and small.
