Y Combinator-backed Sixtyfour is hiring an Operations Associate to bridge its AI research platform with customer success. The P25 batch startup, founded in 2025 with a 12-person team in San Francisco, builds AI agents that discover, link, and reason over people and company data — turning that intelligence into automated research workflows for sales, recruiting, and marketing teams.

The role sits directly in the sales and growth motion. Instead of traditional support, the associate proactively uses the Sixtyfour platform to curate data samples that demonstrate what custom datasets prospects can generate. Each sample undergoes review for accuracy, completeness, and deduplication — zero errors permitted. The associate manages 7–10+ concurrent requests across Slack, email, and CRM, acting as first responder in shared channels while tracking engagement and flagging churn risk.

Technical coordination is explicit: the role translates customer feedback into actionable context for engineering, joins daily standups, and participates in CRM syncs. The interview process includes a take-home assignment followed by a one-week paid onsite — a signal the team values hands-on evaluation over credential filtering.

This hire reveals how early-stage AI infrastructure companies operationalize quality: by embedding data craftsmanship into the pre-sales motion, they turn platform capability into tangible proof before a contract lands.
