Turning green innovation into market-ready solutions.
GreenUp Accelerator supports startups and teams developing green chemistry, climate, environmental and circular economy solutions through mentorship, expert workshops, market validation, and access to partners, investors and commercial opportunities.
Our Core Focus Areas
Green Chemistry & Safer Materials
We support solutions that apply green chemistry principles, safer materials and cleaner production approaches to reduce pollution, improve resource efficiency and lower environmental impact.
Circular Economy & Resource Efficiency
We help teams build solutions that reduce waste, extend product and material lifecycles, improve resource use and create circular business models with real market potential.
Climate & Environmental Technologies
We work with startups developing technologies that support decarbonisation, energy efficiency, pollution prevention, environmental protection and more sustainable industrial processes.
Who We Support
Early-stage Teams
For teams developing ideas, proof-of-concepts, pre-MVP or MVP solutions in green chemistry, climate, environmental and circular economy fields.
Research-Based Ventures
For technical and scientific teams working to turn research, lab results or environmental innovation into practical products, services and scalable business models.
Growth-Ready Startups
For startups with validated solutions, early traction or clear market potential that are ready to strengthen their business model, reach customers, build partnerships and prepare for further growth.
Expert Mentoring
Selected startups work with lead mentors and subject-matter experts who help them define milestones, validate their market, improve their products, refine business models and prepare for growth.
Mentorship is tailored to each startup’s maturity level, with practical guidance focused on clear next steps, measurable progress and access to relevant partners and opportunities.
Practical Workshops
GreenUp workshops help startups turn technical ideas into practical business progress. Sessions cover customer discovery, market research, green business models, regulatory basics, product development, IP, financial planning, fundraising, sustainability metrics, pitching and storytelling.
Each workshop is designed to give teams clear next steps for validating, improving and preparing their solutions for the market.
Market & Customer Validation
GreenUp helps startups test whether their solution addresses a real market need, understand customer pain points, assess competitors and define a clearer path toward early adopters, partners and commercial opportunities.
The focus is practical: what problem is being solved, who needs the solution, why it matters, and how it can become viable beyond the programme.
Joint Venture Initiative
The GreenUp Accelerator is a joint initiative of the Global Green Chemistry Innovation and Network Program (GGCINP) and GreenUp Hub, supporting green innovation and sustainable entrepreneurship in Serbia.
GGCINP is a UNIDO/GEF-funded initiative coordinated by Yale University and implemented by the Faculty of Technology and Metallurgy, University of Belgrade.
GreenUp Hub was launched by ICT Hub with the support of GIZ.
Together, these two initiatives provide support for developing and accelerating innovative solutions in green chemistry, clean technologies, and sustainable business.
