KJ has also been named a “Top 40 Leader Under 40” by the New Leaders Council and a “Person You Should Know” by CNN.

Artem Kozaev


Artem was born in the frigidly cold north region of Russia, where you can see the northern lights in the winter and the white nights during the summer. A software engineer by trade, he holds a Bachelor's in Information Technology and a Masters in Software Engineering. When he isn’t staying up till 4am charging through tickets, you can find him watching soccer (especially BPL) — and sometimes even getting out to play it. Artem also loves good television, especially The Office and The Daily Show religiously. His Russian personality shines through in his love for dystopian fiction authors like Orwell, Huxley, and Strugatsky. He currently works mostly in Ruby on Rails, while maintaining a background in JAVA and .Net.


Will Salinas


Will is an audio enthusiast with a BA in Sound Design from the Savannah College of Art & Design in Savannah, GA. After obtaining his degree, he left the Deep South for Northern California in pursuit of the “NorCal” vibe. There, he worked for Prairie Sun Recordings doing client support and developed critical listening skills allowing him to meet client needs. Loving his work in customer service, Will flew to Nicaragua to work for Delta Security as their Commercial Coordinator & Supervisor of the Electronic Security Department. Soon after, he joined Simbi where he is in charge of Member Care. Besides solving problems for Simbi members, Will also enjoys matching them up with someone who can make their lives a little bit better.


Rene Castellón


Rene has lived in 3 different countries and 4 different states in the past ten years. He began his college education in Madrid, Spain and graduated from the School of Visual Arts in New York City. While Rene lives and breathes art, it isn’t his only passion — he also plays multiple instruments and composes music. He believes that his love of creating and being able to make a difference in people’s lives have been the only permanence he’s carried with him throughout the years. He finds joy in helping others and making a difference, and his role at Simbi enables him to do just that. Apart from Simbi, his favorite place to pass the time is in the water: give him an ocean or a lagoon and you’ll be gifting him a smile as well.


Javier Castro


Javier is a numbers guy and a people person who loves learning and challenges. His previous work experiences include positions as Supervisor/Team Leader, Director of Talent & Culture, and Country Coordinator.
