This week on How to Win: Brian Long, co-founder and CEO of Attentive, an SMS marketing solution. Since being founded in 2016, Attentive had grown to over 1300 employees and recently raised $470M in Series E funding with a total of $866M raised to date. In this episode, we discuss Attentive's vertical focus, obsession with customer feedback, and success with their outbound sales efforts. I share my thoughts on playing in market verticals, adjusting to a rapidly evolving competitive landscape, and how startups should be thinking about their website messaging.
