When your sustainability leadership gap can't wait for a permanent hire, you need interim talent that hits the ground running. Unlike traditional recruitment agencies that focus on placements, we're sustainability practitioners first. Our interim leaders bring immediate credibility, sector-specific expertise, and the practical know-how to navigate complex ESG challenges whilst integrating seamlessly with your existing team.
Whether you're facing an unexpected departure, launching a critical compliance project, or need specialised expertise for a defined period, our interim sustainability leaders deliver results from day one without the premium fees and rigid contracts of conventional interim agencies.
Sustainability Expertise First, Recruitment Second
Traditional recruitment agencies place candidates. We deploy sustainability practitioners. Every interim leader in our network has been vetted by experienced sustainability professionals who understand the nuances of ESG strategy, regulatory compliance, and stakeholder management.
Our vetting includes technical competency assessment, sector-specific experience evaluation, and cultural fit review by sustainability experts, not recruitment consultants.
Rapid Deployment Without Compromise
Most interim placements take 4-6 weeks. We can deploy qualified interim sustainability leaders within 7-10 days because we maintain relationships with a curated network of available professionals rather than starting searches from scratch.
Our streamlined process:
Initial consultation within 24 hours
Candidate shortlist within 3-5 days
Interviews and selection within 7 days
Deployment and handover within 10 days
Flexible Commercial Arrangements
Unlike traditional interim agencies with inflexible fee structures, we offer transparent daily rates without lengthy minimum commitments, scalable arrangements that adjust based on project phases, and just one-month notice periods for maximum flexibility.

The Connection to Our Fractional Model
Our interim service connects to our broader flexible talent approach. Interim leaders typically work full-time for a defined period, while fractional CSOs work part-time on an ongoing basis. Many interim placements naturally evolve into ongoing fractional arrangements, and our fractional CSOs can scale up to interim-level intensity when projects demand it.
