Gus Bartholomew

I'm Gus Bartholomew, the Co-Founder of Leafr, a vetted marketplace of top-tier freelance sustainability specialists.



At Leafr, we connect businesses with the talent they need to deliver their most pressing sustainability initiatives, be that overarching sustainability strategies, Life Cycle Assessments, B Corp certification guidance, Sustainability Software Procurement, or Emissions Calculations. The list is endless, but we have specialists for most companies' needs. Our mission is to empower companies with the talent, knowledge and resources needed to make impactful sustainability decisions.



My foundational entrepreneurial experience comes from SupplyCompass, a B2B SaaS platform I co-founded solving product development and supply chain management for fashion and retail businesses and their supply chains. We raised £2.5m in Venture Capital funding (Episode 1, Ascension & Angels) and grew the team to 30 across the UK and India. This venture was not just about streamlining operations but also about instilling sustainable practices within the industry. I lived and worked in India full-time for 2 years and on and off for 5, visiting over 300 factories which was one of the most fulfilling and enlightening experiences of my career.



After SupplyCompass I honed my skills as a Fractional Exec/Consultant/Advisor to companies in the UK, US, Europe & Asia where I guided B2B & B2C startups and scale-ups in refining their Go-To-Market strategies. My focus was on building optimised processes and teams across Operations, Marketing, Sales, and Customer Success.



With a background in Civil Engineering and being a Chartered Surveyor in Project Management, my career has been a blend of technical expertise and creative problem-solving. My industry experience spans across diverse sectors, including Supply Chain, Fashion, E-commerce, Retail, Sustainability, and more, embracing technologies like AI and SalesTech.
