This document discusses account based marketing (ABM) in the surgical ophthalmology industry. It begins by describing traditional sales and marketing approaches as mass approaches with one-size-fits-all thinking. It then introduces ABM as a more intensely focused and customized approach that targets a small set of high-volume hospitals with individualized marketing. Some key benefits of ABM include aligning departments, reducing sales cycles, focusing resources on high-value customers, and increasing revenue per customer. Critical elements include carefully selecting targets, understanding decision-makers, and designing personalized campaigns. Future developments may include enhanced targeting using AI and more customized content delivery through programmatic marketing.
