William "Billy" H. Mann (born December 20, 1968) is an American songwriter, record producer, creative executive, music publisher, and founder/CEO of independent music publishing company Green & Bloom/Topline, as well as chairman of management firm Manncom.
Over a 25-year period, Mann has built his career from street musician to recording artist to entrepreneur and music industry executive. In the process he has written songs and/or produced records for/with an array of artists, including P!nk, John Legend, Celine Dion, Take That, Backstreet Boys, Cher, David Guetta,Kelly Rowland, Jessica Simpson, Ricky Martin, Anastacia, Art Garfunkel, Sting, Joss Stone, Robyn, Grover Washington, Jr., Chaka Khan, Boyzone, Paula Abdul, Helene Fischer, Cher Lloyd, Paul Van Dyk and Hilary Duff and Jennifer Brown.
Since penning his first Top 10 hit in the UK for EMI in 1995 with "3 Is Family" by Dana Dawson, Mann has racked up several Top 40 hits around the world (including several Top 10s and number 1s), with cumulative album sales of over 110 million.
Born in Philadelphia, PA as the youngest of three children. Born to middle class parents, Mann lived with his mother in Philadelphia's inner city after his parents' divorce. From early childhood, he began experimenting with songwriting and taught himself guitar, piano, bass, harmonica, baritone horn and flute. By age 12, Mann had put together several bands with other young local musicians, including musicians such as Steven Wolf, Clayton Sears and Adam Dorn (a.k.a. Mocean Worker).
A college graduate by 20, Mann immediately began his professional career as a traveling musician. After stops in Los Angeles, San Francisco, Miami and London, Mann landed in New York, where a chance encounter with producer Ric Wake, put together by songwriter/performer Gregg Wattenberg, resulted in a recording contract. Wake then introduced Mann to then A&M Records label head, Al Cafaro; Mann was ultimately signed to Wake's imprint DV8 Records, distributed by A&M.
The deal led to two solo releases: 1996's Billy Mann and 1998's Earthbound. Inspired by the loss of his first wife Rema Hort Mann, to stomach cancer nine months after they were married, Earthbound was co-produced by Mann and David Kershenbaum and featured an appearance by Carole King.
Mann has written songs for artists across a number of genres including pop, rock, dance, R&B, reggae, house and country. Self-publishing his own catalog, he also has publishing credits with Sony/ATV, Warner/Chappell, Verse and BMG Chrysalis. Mann's songwriting collaborators have included artists such as Carole King, Rudy Perez, Burt Bacharach, Desmond Child, Graham Lyle and Walter Afanasieff, as well as new producer/songwriters like Christian Medice, David Spencer and Supah Mario. Of particular note is Mann's long-standing collaboration with P!nk, another Philadelphia native, who was introduced to Mann in 2002 by her then co-manager Craig Logan. They since have co-written such songs as "God Is A DJ," "Stupid Girls," "Dear Mr. President," "Nobody Knows," "I'm Not Dead," "Crystal Ball," "Glitter in the Air," "Bridge of Light," "The Truth About Love" and "Beam Me Up." They have twice been nominated for Grammys, for "Stupid Girls" and "The Truth About Love." In 2017, Mann co-wrote and produced "I Am Here" on P!nk's already million selling album entitled Beautiful Trauma. Variety Magazine profiled the long-standing partnership between the artist and Mann just after the album's release. 
About.com named Mann one of the Top 10 Producers of 2006. In addition to some of the artists listed above, he has worked in a production capacity with such Grammy-winning producer legends as Peter Asher, Walter Afanasieff, David Foster and James Stroud.
In 2001, Mann founded Stealth Entertainment in New York City's garment district. The one-man office and studio grew into a team of a half dozen young executives who went on to develop multi-platinum, award-winning and chart-topping artists, songwriters, producers and mixing engineers like Andy Zulla, Christopher Rojas, Teddy Geiger,Esmee Denters and Pete Wallace, all of whom met Mann at the earliest stages in their careers.
In addition to developing talent, Stealth built successful alliances/partnerships with organizations like Seventeen Magazine, Columbia Records, SonyBMG Special Projects, Target, Levi's and other brands on behalf of the company and its roster. Stealth was acquired as part of Mann's later move to EMI.
As a consultant, Mann has worked with Zomba Group, Sony Music Entertainment, Sony Pictures Television, Warner-Chappell, Lockerz, BMG Chrysalis, Bliss Legal and BMG International. He has also been featured as a guest music commentator on The Today Show
In November 2007, Mann joined EMI Music as creative advisor and a member of the operating board. Soon after, he was appointed chief creative officer; in 2008, he was made president of new music a&r international and president of global artist management, overseeing content on all continents.
During his years with the company, Mann helmed the development of some of EMI's most successful international artists and partnerships, including David Guetta, Pablo Alboran, Helene Fischer, Bebe, Juan Luis Guerra, Tiziano Ferro, Robyn, Panda, Paty Cantu, Belinda, Wind Up and Movic, among others. Additionally, he helped develop artist management initiatives in several countries (including Spain, Germany, Italy and the United States) in order to expand the way EMI developed talent. Throughout his EMI tenure, Mann also acted as the non-executive chairman for Stealth Entertainment, which in its latter years focused primarily on songwriter/producer management.
During EMI's most turbulent period, Mann worked under four CEOs in a mere three years, and carried on through each regime change. EMI's final CEO Roger Faxon announced Mann's departure from the company in a glowing letter that reflected the impact on the organization.
In January 2011, Mann was named president of creative, BMG North America, overseeing the creative staff in New York, Los Angeles, and Nashville in managing the roster integration of recently acquired companies, and leading efforts to attract, develop, and sign new content.
At the end of 2011, Mann founded Manncom Creative Partners, a boutique management/services company alongside a publishing venture with BMG Chrysalis, Green & Bloom/Topline.  In 2013, BMG extended its investment in Green & Bloom.
Mann holds seats on the boards of various digital leaning companies attached to social media and entertainment.
