In recent years, Tim has advised impact-driven ventures on repositioning for growth, strengthening commercial focus, and building credibility with enterprise customers and investors. Alongside this, he supports larger organisations in embedding sustainability into strategy, ways of working, and decision-making — moving beyond ESG reporting toward tangible business and environmental impact.
