How Ubie Scaled to 100 Employees Without an HR Team

Sono-P from Ubie explains how the medical AI startup built a fully distributed hiring model that runs 70% on referrals with no dedicated recruiter.

• Ubie reached 100 employees with zero dedicated HR or recruiting staff; 70% of all hires come from referrals driven by general employee ownership.
• Every employee offer letter explicitly lists recruiting as a job responsibility, signaling from day one that hiring is everyone’s work.
• All interviews are conducted by two or more people, recorded with candidate consent, and interviewers exchange written feedback after every session.
• Job requirement docs go two levels deeper than typical: each trait (e.g., zero-based thinking) includes its rationale, sub-components, scored evaluation questions, and follow-up question trees.
• Interviewer assignment within a function uses a Slack lottery, so any engineer can interview engineering candidates — no single-person dependency.
• The model’s main weakness is external recruiters: with up to 60 people potentially involved, agencies have no clear contact point, so Ubie deliberately deprioritizes agency hiring and doubles down on referrals instead.
• Sono-P frames HR functions as a triangle — ownership mindset at the base, generalist skills like marketing and project management in the middle, and specialist recruiting knowledge at the top, each sourced differently.
