Vendor Relations Manager

Having left academia with a degree in English literature, theatre arts and history; Ansel found that communications and customer service were what he had been training for all along! He still has an active career as a theatre professional, but Purchasing Platform, the e-Marketplace for Procurement gives him a place to help people find and get what they need with a human, possibly whimsical touch. Ansel is an alumnus of Beloit College and has studied at Loyola University in Chicago and The University of York in the UK. He is known to the podcasting world for his work on Our Fair City and Starlight Radio Dreams. His facial hair game is on point.



Member Services & Marketing Manager

With a face for radio and a passion for life, Kate is used to tackling any trouble and having fun along the way. Her work in the Chicago Theatre scene has taught her the value of excellent people and problem-solving skills (as well as sword fighting) and she is happy to bring a smile to the face whenever she can. She believes in having courage and being kind… and what better place to do so than with Member Services and on Social Media? Kate holds a BFA from Northern Illinois University and has studied with the Moscow Art Theatre School.

Konstantin Ivanov


Senior Software Engineer

Konstantin began to study programing when he was 14 years old. He likes to trace his mind to find out how the human brain solves tasks. In this way, programming became a way to know himself. He has been working with small teams on the enterprising level, as well as private projects, and his contributions range from developing components for ERP systems to entire web applications. He believes that programming (and software) is hardware-psychology, or “psychology of the machines.” He enjoys playing piano, and it is even a little bit good when he has had enough time to practice.
