Milan, Italy, NY, USA — March 18, 2019 — Kaleyra S.p.A., a rapidly growing cloud communications software provider delivering secure application programming interfaces (APIs) and connectivity solutions in the API/CPaaS market, today announced the appointment of Julia Pulzone as Chief Financial Officer (CFO), effective immediately. She will be based in the company’s office in Vienna, VA and report to Mr. Dario Calogero, Kaleyra’s Founder and current Chairman of the Board and Chief Executive Officer. Ms. Pulzone takes over for Luca Giardina Papa who will remain a member of Kaleyra’s executive team and steering team.

Ms. Pulzone brings to Kaleyra more than 20 years of financial management expertise in several private and public middle-market technology companies focused on both healthcare technology and software. Ms. Pulzone most recently served as the Chief Financial Officer of Cureatr, Inc. Prior to that, Ms. Pulzone served as the Chief Financial Officer of CodeRyte, Inc., a company sold to 3M in 2012. Ms. Pulzone’s previous experience includes serving as a managing director of the Global Environment Fund private equity firm, in addition to several senior financial management positions, including as its CFO. In 2013, Ms. Pulzone was named one of the finalists for the Northern Virginia Technology Council’s “Chief Financial Officer of the Year” award.

Ms. Pulzone holds a Master of Business Administration from the Robert H. Smith School of Business at the University of Maryland, and a Bachelor of Science degree in Accounting from the University of Maryland. Ms. Pulzone is also a Certified Public Accountant.

“I am very excited to welcome Julia to the Kaleyra team,” said Mr. Dario Calogero. “Her extensive CFO background uniquely qualifies her to lead our finance team as well as to help drive the company to the next level of performance. Julia will assure a smooth and strong transition as Kaleyra is expected to move from a private to public company later this year.”

“I look forward to making a positive impact at Kaleyra, to partnering with Dario and the rest of the leadership and finance team, and to help further grow Kaleyra’s business,” said Ms. Pulzone. “Following the recently announced combination with GigCapital I believe this is an excellent time to join Kaleyra. I am excited about the opportunity to capitalize upon the strengths of the newly combined company when the transaction closes in the second half of the year and lead Kaleyra’s finance organization through the transition to a publicly traded firm.”

“The GigCapital team is pleased Julia has joined the Kaleyra team. Her blend of CFO experience with both public and private companies is an excellent match for the needs of Kaleyra both today and going forward,” said Dr. Avi Katz, Founder, Executive Chairman of the Board, and Chief Executive Officer of GigCapital, Inc. “Julia is joining an exceptional team of solid and respected entrepreneurs being led by Dario, and we look forward to her contributions as Kaleyra continues on its path of rapid revenue growth and stronger financial performance prior to the consummation of the combination with GigCapital, and for the years to come after, as Kaleyra Inc.”
