When repeat founder Brian Long set out to build a text communication platform for businesses, he soon realized that the first version of his product didn't have the market pull he was looking for. After a pivot, Brian found himself building Attentive, the comprehensive mobile messaging platform for brands. Six years in, Attentive has become a major player in the e-commerce space and counts thousands of major brands as customers, from CB2 to Michaels. On average, Attentive drives 20% of total online revenue for its customers. Brian shares how he managed hypergrowth in 2020 as customers grew by 270%, why he always asks for quantitative feedback in every customer conversation, and why his unusual trick to destress at work is through reading World War II books.
