Alex Steffen (Worldchanging's co-founder and editor, for those just joining us) is well known as a writer, editor and blogger, but he also is a popular public speaker, giving many talks a year at leading companies (including Nike, IDEO and Amazon), universities (including Harvard, Stanford and Yale), cultural institutions (from Barcelona's CCCB to the Danish Architecture Centre) and major conferences (including TED, Copenhagen's Bright Green, Design Indaba, Pop!Tech, Picnic and South by Southwest, as well as numerous professional associations).
Alex speaks about a variety of subjects, ranging from sustainable business to urban innovation, design solutions to planetary futurism (you can follow Alex on Twitter at @AlexSteffen).
If you'd like to book Alex for your own event, the good people at the Lavin Agency (which represents Alex) can help arrange that for you: a good place to start is with Alex's speaker page.
In addition, Alex is available as a consultant for appropriate projects, and can be contacted through his soon-to-launch new website AlexSteffen.com.
