Innovators are the lifeblood of the cleantech theme and the heroes of our story.

Cleantech Group tells the world. Do we know you?

Innovative companies are who we follow – those with solutions to the world’s massive, and growing, environmental and climate challenges. Make sure you are on our radar!

The insights we share with clients – on trends, on sectors and sub-sectors, on the key companies and players to get to know – are built off the world’s most extensive coverage and classification of the relevant private start-ups and scale-ups.

> 37,000 companies have a searchable company profile on i3, our research platform. Do you?

To see if you’re in our platform, simply go to and use the search box to find your company. 

If it’s there, you’ll see a limited profile.  If your profile does not have an owner, you can “Claim this profile” to become the owner and you will be able to update it with your key information.

If your company is not in i3, select “Create your free startup profile” to begin the process.  Once approved, you’ll be able to highlight key information about your business model, differentiators, financial backing, partnerships, and leadership teams so that corporates and investors can view your profile and quickly assess a potential fit.

Although our services are primarily built to help corporates, public sector organizations, investors and others, we have indirectly helped hundreds of start-ups over the years. The most typical ways we help:

Capital-Raising. Innovators tell us we’ve catalyzed numerous successful investor/company introductions and meetings.

Technology Validation. We’ve helped companies secure critical pilot projects with a reference corporation.

Awareness. Our audiences discover companies through our research – be that behind our paywall (with sector-based reports or by searching our research platform), or through our public-facing blog, Cleantech Group Perspectives, or through our programs, like the Global Cleantech 100, the Cleantech 50 to Watch, and the APAC Cleantech 25.
