Tell Me About Yourself and Green Project Technologies
My name is Sam Stark, and I have a background in sustainability and finance. I founded Green Project Technologies after working on the energy team at Goldman Sachs, where I saw firsthand how far many global corporations were from meeting their climate commitments. I started Green Project in 2021 with a few college friends and have since grown it to more than 75 employees.
Our mission is to help companies decarbonise the most difficult area to address – supply chains. We operate across three continents and five countries, serving thousands of companies, including large multinationals and global leaders.
Personally, I am an avid hiker and outdoor enthusiast, and I have been recognised as a Forbes 30 Under 30 and Huffington Post 20 Under 20 honoree.
What Inspired You To Start Green Project Technologies and What Problem Were You Trying To Solve?
I wanted to reduce the impact of climate change but wanted to find help businesses build a sustainability strategy that does not come at the expense of productivity and performance. What I saw missing in the market was alignment between sustainability and profitability.
Too often, companies view climate action as a cost rather than an opportunity. I believed supply chains were the ideal place to change that mindset, since they represent both a major source of emissions and a major lever for cost savings, resilience, and efficiency. Green Project was founded to prove that doing the right thing for the environment can also create measurable business value.
What Has Been Your Biggest Challenge So Far, and How Did You Overcome It?
One of our biggest challenges has been navigating the politicisation of climate change and the resulting shifts in the regulatory environment. These changes can quickly impact how companies prioritise sustainability initiatives. To address this, we evolved our positioning from being purely a sustainability company to becoming a supply chain resilience and efficiency partner.
By helping businesses reduce costs, strengthen supplier relationships, and improve operational efficiency, we ensured our value proposition remained relevant regardless of regulatory trends, while still delivering meaningful carbon reduction outcomes.
Can You Describe a Pivotal Moment That Significantly Shaped the Direction of Green Project Technologies?
A pivotal moment for Green Project came in 2023 when we accepted a majority investment from the Dutch company ACT Group. This partnership provided growth capital, but more importantly, it expanded our capabilities. Prior to the investment, our core focus was on measuring carbon emissions. ACT brought deep expertise on the reduction side, allowing us to move from insight to action. This shift fundamentally changed our offering by enabling clients not only to understand their emissions, but to actively reduce them at scale.
How Do You Define Success?
For your business: Success for the business is measured by two closely linked metrics – revenue generated and carbon emissions reduced. The more we grow, the more emissions we help eliminate, which means commercial success directly translates into environmental impact.
As a founder: Personally, success means continuing to adapt as the company evolves. As we scale, my role has shifted from hands-on execution to leading and empowering people. Embracing new tools like AI across the business is one way I ensure I am growing alongside the company.
What Advice Would You Give To Someone Thinking About Launching Their Own Startup?
It has never been easier to start a company, especially with the acceleration of AI tools that lower costs and speed up execution. Because of that, the most important thing is not the technology, but finding a real problem that customers genuinely care about. Focus on solving something painful and measurable, talk to customers early, and iterate quickly. Speed and learning matter more than perfection in the early stages.
What’s Next for Green Project Technologies? Any Exciting Developments We Should Watch Out For?
We are transforming Green Project into an AI-first company. We are deploying agents across every business unit, from engineering and customer success to sales and operations. Internally, this means faster development and better decision-making.
For clients, AI will sit at the center of their experience. A customer will be able to input their business type and supplier locations and instantly receive a tailored dashboard, insights, and recommendations powered by AI, making decarbonisation simpler and more actionable.
Founder’s Five with Sam Stark
Without further ado, here is our exclusive Founder’s Five with Sam Stark.

HubSpot. It may sound basic, but a clean and intuitive CRM is essential for any B2B business. Too many CRMs are overly complex, which delays proper sales hygiene and leads to inaccurate reporting. HubSpot strikes the right balance between power and usability.

It is always worth investing time in properly teaching and onboarding new employees. While it can feel slower in the short term, strong onboarding creates leverage and scale that no founder can achieve alone.
3. One future trend you’re watching
The rapid evolution of AI agents and how they will fundamentally change how work is done across every function, not just engineering.
4. One quote you live by
“Move fast and break things.” Startups win by moving faster than large incumbents. You do not need to be perfect; you just need to be right enough and learn quickly.
