This document discusses the evolution of corporate access technology for institutional investors and investor relations teams. It notes that both investors and IR teams face budget constraints which is driving adoption of technology solutions. There are two main types of technologies - aggregation platforms that provide a unified calendar for scheduling meetings, and direct engagement platforms that allow direct outreach and scheduling between companies and investors. Direct engagement platforms are growing in popularity as they provide more control and transparency compared to traditional channels. Both technology types are expected to continue growing in importance for corporate access, and may eventually converge into a single solution. Maximizing the ROI on investor marketing will involve understanding the strengths and limitations of different channels.
