"Using the i3 platform helps my team search - across many different sectors - for new technologies and business models that are changing the future of energy. i3 provides the insight and connectivity we need: our search on i3 for Demand Response companies resulted in new and promising connections with interesting companies. We've changed our aim, and opened our minds - energy innovation is the future and we want to be a part of that."

External Venture Manager
“i3 is one of the best venture databases and services that I am aware of! It includes profiles of thousands of start-ups, with valuable details such as fundraising status and financial/strategic partners. With a single click, I can connect with start-ups that own their company’s profile in i3. I have had an amazing customer experience with i3 because it offers relevant data, while being fast and easy to use. The affordable subscription offers great value, and I appreciate opportunities to also connect directly with start-ups by attending or sponsoring CTG’s events."

GDF SUEZ New Ventures
“Cleantech Group recently ran an Innovation Campaign on i3, on behalf of GDF-Suez New Ventures. We were very pleased with the results. The Campaign brought forward some interesting companies who were new to us and we are now exploring more advanced discussions, with one in particular. We found the Cleantech Group team to be knowledgeable in their filtering of companies and professional and proactive in their overall execution of the campaign. Thank you for the collaboration.”
