Reasons buyers look elsewhere

- Price-sensitive organizations under 100 employees gravitate toward BambooHR or Gusto for lower total cost of ownership
- Fast-growing companies (50+ new hires/year) need platforms that scale hiring workflows; Hibob's onboarding tools lag competitors like Workday
- Pricing is higher than competitors like Remote.com or Deel, which offer lower per-employee costs for distributed teams
- Missing advanced reporting and custom integrations that teams managing complex payroll or compliance workflows require
- Limited customization for team-specific processes — requires manual workarounds for non-standard hiring or onboarding flows
