It was Mr. Sieg's love of languages that led to the foundation of Renkara Media Group.

As Renkara Media Group's President, Mr. Sieg led the expansion of the AccelaStudy product line to 18 languages and strives to deliver further innovation in language learning for AccelaStudy's millions of users. Through strategic content partnerships and ongoing product development, Mr. Sieg has pushed the total number of Renkara Media Group applications in the iTunes App Store to over 300 with more planned in the coming year.
