Our Management

Years of experience at work for you

Meet our management team. We’re a diverse group of experienced individuals passionately guiding Xceleration towards innovations that create rewarding outcomes for clients.

Ben Levenbaum


More than our CEO, Ben is our leader, encouraging coach, and guiding force.

And with more than 20 years in the industry, and countless satisfied clients to his credit, who better? A native New Yorker, Ben oversees our growth with an eye on the industry and a focus on “what‘s next” as we deliver reward programs across North America and around the world.

Marisa Haehnlein


As a natural born competitor, Marisa makes things happen.

She brings focus and dedication to work, leading a team where, she says, “Everyone wants to be accountable, no one wants to sit quietly, and everyone succeeds when we continually strive to provide a high-level of service.”

Marisa believes there’s nothing better than the challenge of finding the right combination of technology, awards, and account services for clients. For her, a “win” is when we are viewed as a partner not a vendor, leading to the most successful programs for our clients.

Darryl Speach


Darryl Michael Speach rejoins Xceleration after working as the Chief Learning Officer at Majid Al Futtaim Holding, responsible for leading the organization’s learning strategy to create world-class learning opportunities to over 40,000 employees fostering an environment of empowerment, growth and development.

Darryl spent seven years with The Walt Disney Company as a senior manager on the corporate alliance branding team and a Disney University instructor. He worked as the lead consultant assigned to the Disney Institute/McKinsey & Company co-branded joint venture, specializing in helping clients adapt Disney’s CX approach and crystalize a customer-centric culture. He led numerous client engagement teams around the globe including financial services, retail, CPG, healthcare, pharmaceutical, and automotive companies in Europe, the Middle East, Asia, and the USA.

Jamie Bush


Jamie’s always up for a challenge. As vice president of technical operations, he helped launch our biggest client program to-date- although he refuses to take the credit.

“The people who work here are all really passionate about what we do,” he says, “We’re all constantly striving to work at the highest level.” Outside the office, Jamie maintains that hectic pace, racing mountain bikes and BMX.

George Harrington


A self-professed perfectionist, George, our vice president of reward operations, has a perspective that every client appreciates.

“This is an intricate and challenging industry,” he says, “It’s more than points, it’s an entire experience.”

When he’s not running operations, George is still on the run. As a long distance runner, he’s currently training for a 60K. (Yes, you read that right. He is training to run 37 miles.)

Sarah Levenbaum


Sarah won’t hesitate to tell you the best part of her job.

It’s not the shopping – even though as Gravy curator, Sarah’s responsible for tracking down extraordinary gifts that get hearts racing and mouths watering. And it’s not the travel – even though, as senior director of global strategies, Sarah’s devoted to understanding and embracing cultural nuances around the world. Instead, she says the best part her job is always when a client says, “We couldn’t do it without you.”

Rachel Rosenbloom


“I work at Xceleration because I want to make a difference,” says Rachel, our director of client solutions and Atlanta office co-GM.

Rachel oversees client relationships and program development — running them, growing them, and enhancing them. “I’m a relationship person,” she says, which is all the more fascinating when you know, as we do, that Rachel worked in reality television before landing here!

Anna Cork

VP, Employee Experience

“There are a few times in life and your career when who you are and what you have the opportunity to do every day collide in the most perfect way.”

Anna Cork, VP, Employee Experience, describes her role at Xceleration as the type of collision that creates momentum.
She brings nearly two decades of diverse HR experience spanning multiple industries. “I have the opportunity to do what I do best every day” she says.
Anna is a Myers-Briggs INTJ, DISC Objective Thinker, WPB5 N-E+O+A-C+, Standout Connector & Equalizer, PI Captain who leads with the CliftonStrengths of Strategic, Individualization, Learner, Analytical and Input.

Uday Gadireddy


If you think, like we do, of Xceleration as a family- then RewardStation is Uday’s “child.”

Our senior director and lead architect, Uday has devoted 11 years (and counting) to making changes, developing enhancements, and adhering to requirements to achieve client goals.

When he’s not at the office (and sometimes, when he is), Uday’s a huge sports fan (NFL and cricket, in particular) and makes a mean chicken tikka masala. (Ask for the recipe!)

Dara Berman


Dara describes her role at Xceleration in four simple words, “I get things done.”

Dara’s the liaison between Xceleration developers and account managers to, well, get things done. “I want everything we deliver to clients to be as close to perfect as possible,” she says. At home, Dara’s equally passionate about parenting her two young children, and finding opportunities to relax at the beach!
