“Cleantech Group completely gets it! With the Entrepreneur Showcase, they create a very different environment for business development…Likely the highest "return on daily burn" of our business development to date. We'll be back every year!”
-Sanford Ewing, CEO, Tellus Technology, Inc.

“I thought Cleantech Forum San Francisco’s sessions were thoughtful and content-rich, and I loved CTG’s novel approach to speaker engagement. Judging by the amount of post-session dialogues, we hit a responsive chord with the audience! Thanks to Sheeraz and the entire Cleantech Group team for a job well done. Congrats on a fabulous conference!”
-Nancy Pfund, Managing Partner, DBL Investors

-Joe Indvik, Co-Founder, President, and COO, Spark Fund

“A great event with remarkable attendees. I had planned not to spend a third day in SF, but the networking and sessions were so good that I had to BART back for the Forum’s final day. The speed networking was fantastic - I got a broad cross section of connections that were useful in later networking sessions. Well done!”
-Mark Peterman, Co-Founder and CEO, OndaVia

“Cleantech Forum San Francisco is the best place all year to meet people who are important to us in our industry. Cleantech is extremely complicated and it is global. So the only way to have an effective network is to know a lot of people around the world, and this forum is the meeting place for all the movers and shakers in Cleantech globally.”
-Walter Schindler, Managing Partner, SAIL Capital Partners
