Jonas Wandel

Companies lose money daily due to intransparent supplier structures, uncontrolled temporary staffing spending, and a lack of control over external workforce management. This is exactly where I come in.

As the founder and managing partner of SOLUA GmbH, I have built an independent consulting firm that currently manages approximately €150 million in temporary staffing spend annually.

My clients are managing directors, HR managers, and procurement executives in medium-sized and large corporations – those who don't need more consultants to document processes, but someone who understands structures, knows the levers, and delivers results.

I work exclusively at the decision-maker level, with a clear focus on measurable business impact: cost reduction, transparency, governance, and scaling.

Service: Neutral Vendoring & Vendor Management

Development and management of neutral vendor structures for companies with complex temporary staffing spend. I create transparency over suppliers, conditions, and compliance – while demonstrably reducing costs and risks.

Service: RPO & Staffing Architecture

Design and implementation of Recruitment Process Outsourcing solutions for scalable, cost-effective talent acquisition. From conception to go-live – without detours through agencies.

Service: Workforce Strategy & Interim Management

Strategic support for management and HR leadership in realigning external workforce structures. Interim assumption of responsibility during transformation and development phases.
