In this episode of HBR IdeaCast, venture capitalist Heidi Roizen shares insights from her extensive networking experience, which is also the focus of a well-known Harvard Business School case study. Roizen highlights that successful networking is about cultivating authentic relationships rather than just making transactions. She encourages listeners to move beyond merely collecting contacts and instead focus on fostering mutual respect and trust. Roizen offers practical advice, such as being accessible, making thoughtful requests, and consistently expressing gratitude to strengthen professional ties. While she acknowledges the benefits of social media for managing connections, she emphasizes that nothing can replace the value of face-to-face interactions and the serendipity that comes from them in building meaningful relationships.
