Get ready for a startup throwdown of global proportions (literally). We’re the proud hosts of the Extreme Tech Challenge (XTC) Global Finals, and the pitch competition action starts tomorrow, July 22 at 9:00 am (PT).

Pro housekeeping tip: Attending this virtual pitch fest is 100 percent free, but you need to register here first.

Not familiar with XTC? It’s the world’s largest pitch competition focused on solving humanity’s most vexing challenges. You gotta love a competition that serves the greater good — and a startup ecosystem for purpose-driven companies determined to build a more sustainable, equitable, healthy, inclusive and prosperous world.

The road to the XTC finals was crowded to say the least. More than 3,700 startups from 92 countries applied to compete in one of these categories: Agtech, Food & Water, Cleantech & Energy, Edtech, Enabling Tech, Fintech, Healthtech and Mobility & Smart Cities.

Talk about a daunting endeavor. Team XTC, which consisted of deeply experienced investors, entrepreneurs and executives, winnowed down that field to these seven competing finalists: Wasteless, Mining and Process Solutions, Testmaster, Dot Inc., Hillridge Technology, Genetika+ and Fotokite.

Tomorrow’s competition takes place in two rounds, and each startup team will have to bring its best if they hope to impress this panel of judges — all leaders in sustainability and social-impact.

Young Sohn, co-founder, XTC and chairman at Harmann International; Bill Tai, co-founder, XTC and Partner Emeritus, Charles River Ventures; Regina Dugan, president and CEO of Wellcome Leap; Jerry Yang, founder/partner of AME Cloud Ventures and co-founder of Yahoo!; Lars Reger, CTO and EVP at NXP Semiconductors; and Michael Zeisser, managing partner at FMZ Ventures.

In a classic, “but wait, there’s more” moment, the day also features several presentations from some of the leading voices in sustainability. Take a look at the two examples below, and check out the complete XTC finals agenda and the roster of speakers.

The Keynote Address: Tune in as Beth Bechdol, the deputy director-general at the Food and Agriculture Organization (FAO) of the United Nations, provides an update on the latest from her agency.

Waste Matters: According to the EPA, the U.S. alone produces 292.4 million tons of waste a year. Can technology help this massive – and growing – issue? Leon Farrant (Green Li-Ion), Matanya Horowitz (AMP Robotics), and Elizabeth Gilligan (Material Evolution) will discuss their companies’ unique approaches to dealing with the problem.
