Iginio Straffi, Italian animator and producer, founded Rainbow S.r.l.
Iginio Straffi is an Italian animator and former comic book author. He is the founder and president of Rainbow SpA, which he co-owns alongside the American media company Paramount Global. Straffi is the creator of the studio's animated series Winx Club and Huntik: Secrets & Seekers, as well as the co-creator of its comic book series Maya Fox.

While at university, Straffi published his first comic story in a 1985 issue of Tilt. He continued to work as a comic book illustrator through the 1990s, eventually becoming the lead creative artist for Sergio Bonelli Editore's Nick Raider series. In 1995, Straffi founded Rainbow with the assistance of Lamberto Pigini and Giuseppe Casali. The studio began with a capital of 10,000 euros, which was mostly used to purchase computers and software for digital design. Rainbow initially provided creative services for other companies until securing funds for original projects.In 2004, Iginio Straffi's creation Winx Club premiered in Italy. The series became internationally successful and attracted the attention of the American media company Viacom, owner of Nickelodeon and Paramount Pictures. After a "long courtship," in February 2011 Viacom became a co-owner of Rainbow, purchasing 30% of the studio and leaving the remaining 70% to Straffi. The purchase was called "Straffi's most important agreement" by L'espresso, as it led to the worldwide distribution of Rainbow's shows by Paramount and Nickelodeon, as well as various co-productions. As of 2019, Straffi continues to work in creative roles at Rainbow, but he has shifted his focus from animation to live action. Among his first live-action works are Nickelodeon's Club 57 and Fate: The Winx Saga, an adaptation of Winx Club.
