Bill Guthy, Founding Principal and Co-Chairman, along with co-founder Greg Renker, focus on new product and brand development. This includes selecting, licensing and developing products that meet the direct response criteria for success and crafting the USP (Unique Selling Proposition) and proper casting of talent that have an associated productstory rather than a traditional endorsement.Raised by his mother above a New York City luncheonette, Guthy experienced a childhood of meager means. He excelled in high school-as editor of the paper, president of the Speech Club and student body vice president-conducting a successful landscaping business on the side. “I always had an entrepreneurial drive, a desire to do better,” Guthy recalls.In 1969, the family settled in Southern California where Guthy followed tradition and attended Ambassador College in the only major then offered, Theology. In his sophomore year, the school broadened its choices and he switched to Psychology, graduating with a B.S. in 1977.While in college, Guthy served as senior class president and paid his tuition by duplicating audiotapes for the Blind Department of the church affiliated with Ambassador. He eventually secured permission to rent the equipment at night and took on independent jobs. Cassette Productions Unlimited (CPU), his own audiotape duplication and packaging firm, was thus born in 1977. Originally operating from his apartment, Guthy soon bought his own equipment and moved into a small office in Pasadena.In 1981, Guthy purchased a home for weekend retreats in Indian Wells, California and began a friendship with Greg Renker, whose family owned the resort. Both men realized they shared a love of motivational books, in particular Napoleon Hill’s “Think and Grow Rich.” Guthy himself was well on his way to financial success, his cassette duplication business flourishing. CPU, now owned by Guthy-Renker, was renamed Guthy Renker Fulfillment Services (GRFS) at the beginning of 2011. It currently employees around 650 people with more than 400,000 square feet of fulfillment distribution and call center space with three locations in CA, LA and NC. ## Investment focus ### Industry | Industry | Investments | Share | | --- | --- | --- | | Email | 1 | 50% | | Payments | 1 | 50% | ### Stage | Stage | Investments | Share | | --- | --- | --- | | Angel | 1 | 50% | | Series A | 1 | 50% | ## Investments | Company | Description | Amount | Stage | Date | Website | | --- | --- | --- | --- | --- | --- | | Zumbox | Zumbox, a paperless postal system, allows businesses to deliver transactional mails electronically to their consumers’ digital mailboxes.This web-based postal delivery and archiving system that provides an online alternative to the U.S. postal service for the secure archiving of transactional mails such as bills, monthly statements,warrantees, health care and insurance materials, mutual fund disclosures, and other household documents.
