  • WorldStar Hip Hop Unveils Website Redesign in Partnership with Grenco Science

    WorldStar Hip Hop, the world’s leading video entertainment platform online, announced today the unveiling of its redesigned website WORLDSTARHIPHOP.com, and Grenco Science is proud to be a part of it. The upgraded site features a visually striking and streamlined format that offers an engaging, entertaining and easily accessible user experience sitewide.

    “The relaunch and redesign of WORLDSTARHIPHOP.com further reinforces our standing as a leading video platform online and presents a true representation of the continued evolution of our brand,” says WorldStar Hip Hop founder and CEO Lee “Q” O’Denat. “From producing critically acclaimed documentaries this year and developing entertaining original content via WorldStar Films, debuting music videos by some of the hottest artists in music to the widely discussed user-submitted content we continue to feature on the site, WorldStar Hip Hop has grown exponentially. As such we’ve created a new website that can accommodate what we have to offer now and in the future to our base of over 30 million monthly visitors” says O’Denat.  

    In conjunction with the site’s relaunch, WorldStar Hip Hop has teamed up with Grenco Science to mark two milestones: the redesign of WorldStar Hip Hop and the debut of Grenco Science’s G Pro Herbal Vaporizer. Founded in 2012, Grenco Science is the first company to take the personal vaporizer to market. With a career background in the music industry, G Pen inventor and owner, Chris Folkerts, has pioneered the brand’s marketing through unique partnerships with some of the world’s leading artists in the hip-hop segment such as official partner, Snoop Dogg, as well as Taylor Gang, G-Eazy, Hit-Boy, A$AP Rocky, Action Bronson, Lil Wayne, Young Jeezy among others.

    "I've been a huge fan of WorldStar since day one, and I am honored to partner with these cultural icons. Being a part of the website's first-ever relaunch is an incredible way to kick off the partnership and I can't wait for everyone to see what Q and I come up with" says Chris Folkerts.

    “Grenco Science CEO Chris Folkerts and his team have built a reputation for innovation with its G-Pen series of products and creative branding alignments with some of the hottest artists in Hip Hop. Once the opportunity presented itself, we looked to them as an ideal partner for the relaunch,” says O’Denat.

    The redesigned site is live now on www.worldstarhiphop.com.
