Director, Innovation Program North America
EDF

"i3 is the most reliable, up-to-date, and best resource for information and insights on startups in my domain of activities, which is pretty broad. When I’m searching for companies, I don’t Google; I use i3 to quickly find the trusted information I need. I also like the new functionalities and services enabled by i3."

Óscar Cantalejo Sánchez
Technology Manager
IBERDROLA Ventures

"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."

Ricardo Angel, PhD
Managing Director
GE Ventures

"At GE Ventures, we use i3 to research companies, market trends and keep up to date with latest deals across spaces ranging from energy management to oil and gas to software. This comprehensive solution also allows us to quickly access data to better understand new spaces."

Bryan Wang, Associate
Nitto Innovations

"I use i3 to connect with companies and new innovations that align with Nitto’s corporate strategy. i3 enables top-down discovery through technology sectors of interest and bottom-up discovery via company profiles. i3 is super useful because it maps competitors directly onto each company’s profile, and this is critical intel for us."

Dorothee Martin
External Venture Manager
Saint-Gobain NOVA

“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."

Giovanni Ravina, Investment Manager
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.”

Innovation face to face: Events


Our i3 platform comes to life at our global Forums and Summits, which convene corporates and start-ups–along with other major players focused on accelerating sustainable innovation–around diverse themes and key geographies.

Creating smarter, better water is our primary focus. In September we will explore technological and business model innovation in the water and industrial and municipal points of view.
