Overview
Spine runs benefits, payroll, and compliance for startups for free.
We do the work by giving teams dedicated senior HR and benefits specialists who operate on top of their existing HRIS (Rippling, Deel, Gusto, ADP). We help companies find better-fit, more cost-effective health plans - reducing healthcare costs by around 15% on average - while running payroll, handling compliance, managing open enrollment, and supporting employees directly in Slack.
30+ startups already use Spine to lower healthcare costs and take hours of back-office work off their teams. Learn more at joinspine.ai or email onur@joinspine.ai
