tracey zhen

tracey zhen

president, zipcar

Tracey oversees our entire whirring operation, from cutting edge mobility innovations to the nuts and bolts of, well, the nuts and bolts. With a career that began in banking and carried her through strategy and management, Tracey brings experience to Zipcar that doubled down on both tech innovation and financial fundamentals. Tracey was a Zipster already when she assumed her role here, having just finished a career at TripAdvisor. There she served as vp & general manager of FlipKey, where she led the travel giant’s rapid growth in to the competitive vacation rental space.

Tracey has lived in New York, London and now finds herself just a healthy walk from Zipcar’s Home Office in Boston. When she’s not busy steering us through the fast paced world of shared mobility, Tracy takes advantage of snowy New England to hit some downhill runs at nearby ski resorts.

Tracey is a graduate of NYU’s Leonard N. Stern School of Business holding dual BS degrees in both Finance and Information Systems.

andrew kupiec

andrew kupiec

vice president, North America - Zipcar / Avis / Budget

Finding the combination of someone experienced in both car-sharing and managing large fleets of vehicles is a unique thing indeed. We found that rare crossover in Andrew, with his years of experience at Avis Budget Group, where he led sales and operations in numerous markets along the East Coast, then joining Zipcar as vice president of sales and operations in 2013.

We’re thrilled to have Andrew’s experience leading tech-enabled fleets and the field teams that bring our services to life for both Avis Budget Group and Zipcar. With Andrew’s blended experience operating brands with multiple use-cases, you’d think he was combining the best of managing large vehicle fleets while delivering an outstanding member experience in car sharing. (OK, that IS actually what he’s doing.)

Before he made his way to the big wide world of automobiles, Andrew spent 8 years in various Sales and Operations leadership roles with Clearwire Corporation and Cintas Corporation.

Andrew holds a Bachelor’s of Science from the University of Pittsburgh and is finalizing a Master’s of Science at Cabrini University.

Scott Rudberg

Scott Rudberg

vice president, technology

With a knack for teamwork and a hankering for technology, we know Scott is the right guy to push the pedal and drive the engine that runs Zipcar; our technology team. Scott steers the dedicated and sharp technology crew who work hard to bring wheels when they want them to over a million Zipsters every single day.

Scott began his career as a missile systems engineer (it IS rocket science), developing his problem-solving, design, and analytical skills. Scott spent over 15 years at software firm Passkey, in roles such as Product Manager, Vice President of Engineering, and Senior Vice President of product strategy.

Scott spends most of his free time chasing his two young kids. When he's not catching his breath, you can find him unwinding to bluegrass music and camping, running, or hiking anywhere with an ocean or lake nearby. Scott loves being outdoors so much that, just like 22% of our workforce, he commutes to Zipcar by bike every chance he gets.

Scott received his Bachelor of Science in electrical engineering from Tufts University, and holds an MBA with a concentration in marketing and IT from Babson College F.W. Olin Graduate School of Business.

Jeff Prus

Jeff Prus

vice president, product and experience

A lotta different things need to come together to create a great Zipcar member experience. It’s not surprising then that our product guy started his career designing semiconductors for Intel. (Like the Pentium, remember those?!) Jeff’s engineering background gave him the passion and eye for creating outstanding customer-driven products.

He’s held roles at industry-defining firms where he led the charge in the arenas of product and marketing. Most notably at VistaPrint, where he helmed the company’s user experience and product management teams to develop its online graphic design platform. He arrived at Zipcar after most recently serving as vp, product management and design for Intuit’s QuickBase division.

With an obsession for making every member’s Zipcar experience a reliably excellent one, Jeff also lives the Zipster life and enjoys boating, fishing, gardening and trying to improve his golf game to better than just “mediocre”.

Jeff’s alma mater is the University of Michigan (his boat is called “Go Blue”), where he earned both a BS in electrical engineering and an MBA, with concentrations in marketing and strategy.

andrew daley

andrew daley

vice president, marketing

More has changed in the world of marketing during Andrew Daley’s career than he could have ever anticipated when it began over twenty years ago. And he wouldn’t want it any other way. Andrew has held key positions at Starwood Hotels, Reebok International and, quite naturally, several start-ups. He has even spent time as the Vice President of Digital Strategy as a Boston-based agency where he helped define digital and community strategies for many prominent brands, like Stonyfield Farm, PRODUCT (RED) and The Rainforest Alliance.

Andrew’s considerable expertise in the nitty-gritty of marketing, coupled with a boundless passion for all things digital, lands him squarely where we need him. Leading the charge to bring the message of ‘wheels when you want them’ to the world, no matter what the media. (Except yodeling.)

Andrew is a die-hard Boston sports fan (shocking for Boston, we know) and home renovator who, more than anything, enjoys spending time with his wife and three daughters.

Andrew holds an MA in Global Marketing from the European Institute of International Communications in Maastricht, The Netherlands.

Len Ho

Len Ho

division counsel

Len's experience with Zipcar is coming full circle: he first honed his craft at large law firms in San Francisco and Boston, at one point representing one of Zipcar's early investors. Since then, he’s worked in-house, leading the legal functions at Game Show Network Digital and Upromise. Len has also handled a variety of legal matters as Senior Counsel at Boston Scientific. He’s got the legal chops to keep us in line, to say the least.

After earning his bachelor's degree in business at the University of California at Berkeley, Len earned his CPA certification working for Arthur Andersen in New York City before attending law school at New York University.

In his free time Len enjoys swimming, tennis, and skiing. Best of all for Zipsters, he loves all things related to cars.

Percy Hoffmann

percy hoffmann

director, global member services

Percy Hoffmann is all about the member in a way no other Zipster can touch. (although we all try) He leads the teams that support and service our multinational (and multilingual) membership, managing membership care centers across regions. Our member’s experience goes beyond Percy’s day-to-day focus, as he keeps us ahead of curve with strategic initiatives that push our operations and services to excel in all manners of member support.

Prior to joining Zipcar, Percy spent two decades in the fast turning mobile and telecom industry, joining when cell phone antennas were extendable and riding through the industry’s broadband paced service and product turnover. During that expanding and disruptive period, he held a variety of leadership roles from customer operations and sales, to business intelligence, and mergers and acquisitions, culminating as senior director, customer operations for AT&T Mobility.

Eric Grey

Eric Grey

director, financial planning & analysis

We see Eric as our financial steward, assuring Zipcar’s short and long-term financial well-being so we can effectively fulfill our mission ‘to enable simple and responsible urban living.’ Before running the numbers at Zipcar, Eric spent a decade developing finance and analytics teams at an array of companies across growth stages which includes Amazon, Trulia, and Etsy.

Originally from New England, Eric is happy to find himself working at Zipcar’s Home Office in Boston after years in the Big Apple. Now back on home turf, Eric spends weekends skiing and hiking the Green Mountains of Vermont and running along the Charles River Basin.

Eric holds a BS in Economics from Georgetown University and earned an MBA in Finance from NYU’s Stern School of Business.
