Role Overview We're looking for a Founding Customer Success Manager to own the relationship with our enterprise customers after they sign. You'll be accountable for adoption, retention, and growth — making sure customers get real value from our models, stay for the long run, and expand their usage over time. You'll be the face of Datalab for every account you own: their trusted advisor, their first call when something matters, and the person keeping their goals moving forward. You will be the commercial and relationship manager who owns the account strategy after a deal has been signed. You'll orchestrate the right people internally so the customer always feels progress. You'll know the product and the customer's architecture well enough to lead most conversations yourself, and you'll pull in Engineering when an account needs it. We also have a long tail of self-serve customers using our API. Many are strong candidates to expand into enterprise contracts, and you'll own that self-serve → enterprise motion end to end — from spotting high-potential accounts to closing the upgraded contract. This role is ideal for someone who thrives at the intersection of customer strategy and technical fluency. You should be comfortable leading executive conversations, working with Engineering teams, be credible talking through an integration, and accountable for commercial outcomes. Day to day, you will: Own the post-sales relationship for a portfolio of enterprise accounts — the trusted advisor and first point of escalation, orchestrating internal resources to keep customers delighted and unblocked. Lead onboarding, drive adoption, and execute technical delivery so customers reach first value fast and keep expanding usage from there. Run the cadence that builds trust: regular check-ins, business reviews, and proactive, continuous value delivery tied to each customer's goals. Own renewals and expansion, forecasting your book and turning healthy usage into larger commitments. Define and drive the self-serve → enterprise expansion strategy, spotting high-potential API accounts and converting them into contracts.
