Working Muses is a marketing consultancy that brings ideas, inspiration, new life and strategic creativity to brands looking for a spark!


With more than 75 years of combined experience working for many of the world’s largest companies, brands and agencies, Matthew Glass and Jennifer Granozio have dreamt up and pulled off award-winning campaigns that have generated enormous media coverage, social buzz, sales growth and brand loyalty. From award-winning experiential events to branded radio shows, television programs and books to multi-year sponsorship activations and retail pop-up stores, these marketing thought-leaders continue to break barriers and deliver fresh and results-driven marketing concepts.

Matthew and Jennifer began their professional partnership more than 30 years ago when they started together at Dentsu Advertising to market and manage JVC Electronics’ sponsorships of the JVC Jazz Festival, Eric Clapton and Bonnie Raitt US tours. Then after four years working together to build the in-house marketing department at Lincoln Center for the Performing Arts and two years as heads of marketing, sponsorships and ticketing for the U.S. Comedy Arts Festival in Aspen, they created Grand Central Marketing, which for 15 years was a ground-breaking creative force in the world of experiential marketing. In 2013, the agency was acquired by Allied Global Marketing where Matthew and Jennifer built that business up to $23 million in annual billings and created industry-shaking events for clients including Amazon, Netflix, March of Dimes, American Express, HBO, Warner Bros. and many others.

Today Matthew and Jennifer are excited to again be helping brands and agencies in need of sales and marketing insight, direction, and inspiration.
