About Lightfield

Lightfield is a next‑generation CRM that automatically captures customer interactions such as emails, meetings, and support tickets and organizes them into structured CRM data, enabling deep analysis of customer activity and powerful automation. Unlike traditional CRMs, Lightfield continuously learns from how you sell and who you sell to, directly from the words of customers and actual workflows in the system. With this data, Lightfield proactively manages customer tasks, automates personalized customer communication, and delivers the visibility and insights needed for teams to continually refine their go‑to‑market strategy. The company is initially focused on becoming the first comprehensive system of record and go‑to‑market platform for high‑growth technology companies, with a flexible and scalable model for data capture and organization that is designed to make Lightfield the last CRM and GTM‑automation tool our companies will ever need. Our team previously built Tome, a generative AI presentation product used by over 25 million people, gaining deep expertise in context management, effective evaluation loops, and user‑interaction design for generative AI. Prior to Tome, many of us worked on Llama, Instagram, Facebook Messenger, Pinterest, and Salesforce.
