Our automated customer engagement platform helps merchants engage customers and drive revenue.

As competition for customers’ attention intensifies, it has never been more important for brick and mortar businesses to have a 360° view of the people that keep them in business.

Unfortunately, aggregating and understanding customer data is riddled with resource and technology challenges, so many businesses are flying blind when it comes to using customer data to drive revenue. Thanx solves this challenge by providing offline businesses with a single system of record for customer data and an automated way to engage with customers that is proven to drive revenue. While the vast majority of customer engagement and loyalty programs today are languishing, Thanx has the highest retention rate in the industry thanks to its frictionless customer and merchant experience. Founded in 2011, with offices in San Francisco and Denver, Thanx is financed by Sequoia Capital, Icon Ventures, and other elite Silicon Valley investors.

The Thanx story.

Thanx was founded by Zach Goldstein, a Stanford MBA and former Bain & Company consultant who worked closely with national technology and retail companies, helping them develop strategies around customer satisfaction and customer retention. Seeing a huge need for a modern approach to loyalty, Zach assembled an A-list team, including Aaron Newton on Product and Darren Cheng on Engineering, to build the Thanx platform. Since raising its Series B round of funding at the end of 2016, the company has grown more than 250%, adding new employees across every function, and increased the customer base by more than 70%. We remain just as excited today as we were in 2011 around the opportunity to keep innovating on an awesome product and growing an industry-changing business.

Our Executive Team

Zach Goldstein

CEO and FOunder

Zach founded Thanx in 2011 with the goal of helping merchants identify, reward and retain their best customers and 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

engineering lead and co-FOunder

Darren was born-and-raised on the East coast but is enjoying the West coast life. He joined Thanx as employee and engineer #1 in 2011 and has loved 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 and 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 work here and there, much to the chagrin of the engineers.

Sam Parker


With a career that includes managing all functions within the enterprise, Sam is the obvious choice to champion the customer experience at Thanx, and ensure that the right resources are focused on the right opportunities. Prior to Thanx, Sam was the COO at Recurly, a SaaS provider of subscription management infrastructure. He graduated from Yale University with a B.A in History.

Dave Collier

VP Sales

Dave Collier is the VP of Sales at Thanx. He joined to lead the growing sales team and manage the Denver office. A sales veteran, Collier was most recently Vice President of Global Sales at HotSchedules, which served the restaurant and hospitality industries. Previously, he spent more than a decade at Oracle, serving in senior sales roles.

Qaseem Shaikh

Head of Engineering

Qaseem leads Thanx’s Engineering team. He has more than 12 years experience building teams and products in a variety of industries. He was an early engineer at Amazon Web Services, Climate Corp ($1.1B acquisition by Monsanto) and was most recently VP Engineering at Zenefits. Qaseem has an M.S. in Computer Science from USC.

Thanx is backed by leaders in the venture capital community.

…and is advised by the best and brightest in the industry.
