The team


Zach Goldstein

CEO & Founder

Zach is a die-hard Sacramento Kings fan; it was through many losing seasons where he first learned the value of loyalty. He founded Thanx in 2011 with the goal of helping merchants identify, reward and retain their best customers / die-hard fans. Previously, Zach worked with retail and tech giants at Bain and Company, where he focused on customer satisfaction and retention. He received his MBA from Stanford and shivered his way to a BA at Dartmouth.


Darren Cheng


Darren is a born-and-raised East-Coaster, currently enjoying the West Coast life. He joined Thanx as employee and engineer #1 in 2011 and has enjoyed cultivating the codebase from its inception to what it is now. Darren received his BA in Computer Science from Dartmouth.


Aaron Newton

Head of Product & Co-Founder

Aaron is a veteran of too many startups to keep track of anymore, the most recent being Cloudera where he was employee #6. He focuses his passion for data — and its potential to impact consumer behavior — on the Thanx product. He chips in with some code and design work here and there, much to the chagrin of the engineers and designers.


Davy Wentworth


Davy spent ten years as a technical artist in the visual effects industry before making the jump to startup life with Thanx in 2012. While contributing throughout the stack, he focuses on and enjoys front-end development.


Mark Bult


Mark has worked with nearly two dozen early-stage startups, establishing their brands and user experiences. Previously, he was employee #8 at Fitbit, building their design team and overseeing the design of the consumer experience from package to product. Mark also freelanced for over ten years, working with every type of organization, from record companies to biomedical to nonprofits.


Marc Fernandez


Marc (with a C) is a Spaniard / Catalan guy that landed at Thanx in October of 2012 after stints at big companies like Apple and HP. The thing he likes the most about Thanx is developing through the full stack and making an impact in the growth of the company.


Brian Hollinger


Brian is an experienced Software-as-a-Service professional with a focus in customer relationship management. He is a former sales leader at and has worked with some of the country’s most respected companies – including Disney Parks and Resorts, Sony, and BlueShield BlueCross – to improve their operational efficiency and communications.


Caroline Jaquiss

Merchant Success

Caroline joined Thanx after working with Blackboard Mobile and in a variety of media production roles (including a brief stint as a PA for “18 Kids and Counting”). She is an avid traveler, and spent nearly 7 months in Southeast Asia upon graduating from Vassar College. Now, Caroline loves directing her enthusiasm and energy towards generating strong and successful relationships with our merchants.
