Gett to Appoint Enterprise Software Veteran Ruth Sun to Board of Directors to scale industry-leading GTM platform

Sun brings over 25 years of technology leadership with strong focus on growth at scale

Gett, the leading corporate Ground Transportation Management (GTM) platform and B2B marketplace, today announced that it expects to add Ruth Sun, CEO of Tempest and recognized leader in scaling technology software-as-a-service (SaaS) companies, to its board of directors upon completion of the business combination with Rosecliff Acquisition Corp I (RCLF). Sun brings 25 years of experience in scaling a wide breadth of SaaS technology companies to create long term value at a time when Gett continues to revolutionize the antiquated corporate GTM market.

"With a $100 billion global market ripe for disruption, we believe Gett has a tremendous opportunity to grow faster and expand our competitive advantage in corporate GTM and spend management. I'm thrilled that Ruth is expected to join our board of directors and look forward to her leveraging her decades of experience scaling some of the most well-known technology companies as Gett embarks on its next phase as a public company," said Dave Waiser, CEO and co-founder of Gett. "At every step of her career, Ruth has been responsible for transformational growth while maintaining commitment to diversity and inclusion."

Prior to her role as CEO of Tempest, where she has led the health tech company to revolutionize the business of alcohol recovery, Sun served as Chief Operating Officer at Force Therapeutics, responsible for business strategy, go-to-market, product and R&D. Before that she was the EVP of Growth at Welltok, where she led the company's SaaS expansion, and VP of Strategic Development at Blackboard. Ruth began her career at IBM where over 18 years she rose to be Managing Director of Watson Health, responsible for helping the company redefine a market segment with data and technology. Additionally, Sun was the President and Co-founder of Sun Medical, which was acquired by Hackensack Meridian Health in 2020.

"What Dave and Gett are building is integral for serving today's remote work culture, offering companies all over the globe a single pane of glass for safe transportation while also helping them reduce their ground transportation spend," said Sun. "Over the past 25 years, I've personally experienced the pains of corporate GTM as both an employee and operating executive, so I'm eager to help the Gett team to accelerate their ambitious growth plans to transform an outdated, inefficient category that is ripe for disruption and deliver both client and investor value."

Additionally, Sun has been a long-term proponent of building technologies that abide by an ESG mission, which will be invaluable to Gett as it helps corporations improve their sustainability footprint while also thoughtfully supporting their employees.

Gett continues to expand its cloud-based B2B marketplace for ground transportation, serving over a quarter of Fortune 500 companies. Gett aggregates over 2,000 fleet partners in one standardized platform where corporates are able to manage all their ground transportation spend, which covers an array of options, from regulated taxis to ride-hailing to corporate cars and limos, with notable partners such as Lyft, Ola, Curb, Green Tomato Cars, Excel Executive, Carey, Careem and Cabify.
