Why Spikesz exists
Sonja Lekahena has spent 25 years delivering enterprise HR technology: 40+ implementations across SAP SuccessFactors, Workday, Employee Central Payroll, Personio, HiBob and ServiceNow HRSD, including global payroll, multi-country rollouts and post-go-live stabilisation.
Across those years she has seen the same pattern repeatedly. The platform goes live as an MVP. The project closes and the team moves on. The backlog of value-adds is parked for later, and later never comes, because no one owns it. Roles, policies and processes change while the system stays still. A platform that launched at part of its value slides lower, and spreadsheets quietly fill the gaps.
Most AI consultants do not understand HR operations. Most HR consultants do not understand HRIS implementation reality. Most vendors are selling software. Spikesz sits in the gap: the bridge between HR, HRIS, Payroll, IT, Legal and AI vendors, anchored in what it actually takes to run these platforms after the project ends.
