Lightfield is an AI-native CRM that automatically assembles customer data from email, calendar, and meetings, turning interactions into organized context—accounts, tasks, follow-ups, and insights. The company is backed by Greylock, Lightspeed, and Coatue, with founders who previously built Tome (25M+ users) and team members from Llama, Instagram, Facebook Messenger, Pinterest, Google, and Salesforce.
As Founding Customer Success Manager, you will own the customer journey from signature through expansion for Lightfield's most important accounts. Nearly 2,000 companies have signed up since November 2025 launch; your role is to migrate them onto the platform, get their business running smoothly, and drive continuous adoption and growth.
Key responsibilities include: migrating customers onto Lightfield and ensuring rapid time-to-value; building workflows and automations so the platform handles work customers previously did manually; driving team-wide adoption until Lightfield becomes their daily operating system; identifying expansion opportunities and growing accounts as customer needs evolve; and working closely with product and engineering to stay connected to customer outcomes.
You will start with hands-on account work and grow into larger customers and broader responsibility as you build the function. You'll report to the Head of Customer Success and be the first dedicated CS hire, shaping how the function scales.
Required: 4+ years in customer success, account management, or solutions consulting at technical B2B products, with a track record of carrying your own book and hitting numbers. You must have owned accounts end-to-end from onboarding through expansion, built automations and workflows directly in products, turned around stalled accounts, and engaged founders and VPs as a peer on their business strategy. You teach customers so effectively they eventually outgrow needing you. Bonus: experience with consumption or usage-based pricing models.
