About Lightfield Lightfield is an AI-native CRM that assembles itself from your email, calendar, and meetings. It captures every interaction and turns it into organized context: accounts, tasks, follow-ups, and insights, so nothing slips through the cracks. We’re rethinking CRM from first principles. Instead of forcing teams to maintain rigid systems, Lightfield learns from how companies actually work, adapting, automating, and surfacing the insight that drives growth. We’re building the CRM platform we always wished existed: fast, intelligent, and genuinely helpful. We are backed by Greylock, Lightspeed, and Coatue, and our founders previously built Tome, a generative AI presentation product used by over 25 million people. Before Lightfield, our team worked on Llama, Instagram, Facebook Messenger, Pinterest, Google, and Salesforce.

Lightfield is an AI-native CRM built for the modern era, designed to replace legacy tools like Salesforce and HubSpot by assembling itself automatically from a team's email, calendar, and meetings — capturing every interaction and turning it into organized context: accounts, tasks, follow-ups, and insights, so nothing slips through the cracks. The company's mission is to become the definitive system of record for the AI era, rethinking CRM from first principles so that instead of forcing teams into rigid systems, it learns from how companies actually work, adapting, automating, and surfacing insights that drive growth. Lightfield is backed by top-tier investors including Greylock, Lightspeed, and Coatue, and its founders previously built Tome, a generative AI presentation product used by over 25 million people; the broader team brings deep pedigree from Llama, Instagram, Facebook Messenger, Pinterest, Google, and Salesforce. Traction has been exceptional: over 3,000 companies have signed up since the November launch, with 100+ new sign-ups every week and roughly 30 converting to paying customers weekly — with notable customers including Substack and Distill. Lightfield operates a dual go-to-market motion, pairing a high-velocity self-serve PLG funnel with a direct sales motion targeting Series A/B startups, and is scaling its team rapidly. The culture is high-intensity, mission-driven, and in-office four days a week (Wednesdays from home), attracting missionaries over mercenaries who are genuinely excited about building a category-defining company — and uniquely, Lightfield sells to its own avatars, meaning the product team has enormous appetite to fulfill the needs of the CS and GTM functions using the product itself.
