Actualizer Events and Entertainment began as a dream built from the ground up by its founder—Managing Director and talent manager Stephanie Sandiego, one of the pioneers of the Manila acoustic scene that made waves in the early 2000s.

The company started as Humble Beginnings Entertainment Production and Management in 1999—a fresh venture by then industry neophyte Sandiego, who after 10 years in the sales industry, decided it was time for a new beginning. She resigned from her post as the Vice President of a pre-need company and finally pursued her first love: music.

Sandiego patiently learned the ropes of the industry—researching on music management and band bookings. Eventually, she gained talents of her own. Among her first artists was project band Park Avenue, which she and a few friends curated to include backline members from music heavyweights Circus Band, Powerplay, Mulatto, and Hotdog. She also handled all-male acoustic recording artists Art of Dona, and later booked alternative band Make Your Momma Proud, which she later turned into acoustic band MYMP.

Her talent pool for bookings eventually grew to include newcomers who eventually made names for themselves in this business: Madonna Decena (Britain’s Got Talent semi-finalist and Manny Pacquiao Band lead vocalist), Jeazelle Grutas (Zelle), Alexis Montemayor (General Luna), Lee Grane (The Voice of the Philippines), Marco de Leon (Paramita), Doc Eric (Daddy’s Home), Anna Melissa (Vanna Vanna), Metafour, First Circle, and DV8 (popularized Ivory shampoo jingle “Ang Gaan Gaan ng Feeling”).


Three years later, in September 2003, Sandiego hired an ace team of event managers to mount the company’s first major event—a charitable undertaking produced in cooperation with the Philippine Charity Sweepstakes Office (PCSO) and the Quezon City Chamber of Commerce. This event, a two-day benefit concert and anti-drug campaign titled “Strong Youths for a Strong Republic” featured RnB band South Border and Asia’s Songbird Ms. Regine Velasquez.

In November of the same year, the newly-constructed event arm produced “All Strings Attached,” a mini-concert for the 2003 Miriam College High School Fair that showcased the hippest names of the decade: RnB Prince Jay-R, RnB siren Arnee Hidalgo, and RnB band Passage. In December, it co-organized Diether Ocampo’s concert in Baguio City.

A year later, Actualizer was awarded “No. 1 Events Management Company” at the 2004 Business Excellence Awards—a recognition that further tightened its grasp in the event industry.

Gaining momentum, the team went on to organize a string of branch openings, conferences, award ceremonies, weddings, private functions, activations, and corporate events, among others. In 2007, business conglomerate SM Prime Holdings enlisted Actualizer to co-organize SM Mall of Asia’s first grand anniversary celebration and mall-wide parade.

Through the years, Actualizer has mounted a variety of events including fund-raising shows for Tahanang Walang Hagdanan; benefit concerts for cleft-palate children and cancer patients; and various charity events for GMA News and Public Affairs.

Now, more than decade later, Actualizer has created a reputation anchored on professionalism, innovation, and excellence—bringing creativity and time-tested skills into play to create not just events, but unforgettable experiences.
