About me

yannig roth at sempl15My name is Yannig Roth, I am Marketing Manager at eYeka, one of the world’s leading creative crowdsourcing providers. eYeka’s community members, who come from more than 160 different countries representing all continents, participate in creative contests to express their creativity and to connect with leading brands to solve real-world problems with fresh ideas. At eYeka, I am responsible for all things related to lead generation, branding, advertising, PR, competitive intelligence or research coordination.

I am also a PhD student in marketing at Université Paris 1 Panthéon Sorbonne (France) where I am being advised by Jean-François Lemoine. My thesis deals with creative crowdsourcing, especially with the use of crowdsourcing for innovation and/or marketing by big companies. This technique is increasingly used since the 2000’s, as this regularly updated, interactive crowdsourcing timeline shows. Based on the data of this timeline, I have created the “The State of Crowdsourcing in 2015” trend report, which you can download for free on eYeka.

This blog allows me to write about various subjects (crowdsourcing, co-creation, marketing, design, innovation…), to share some posts about my research (download my academic CV here).  I also like to blog about sports, my favorite books, conferences I attended or other events, because we all benefit from sharing knowledge. If you want to get in touch, contact me here.
