Portside Strengthens Leadership Team for Its Next Phase of Growth

RALEIGH, N.C., September 8, 2026: Portside, a leading provider of AI-enabled, cloud-based software for global aviation, today announced four leadership appointments: David Kim joins as Chief Product Officer, Roman Mogylatov has been promoted to Chief Technology Officer, and the company has added Jon Ingram as Chief Financial Officer and Alexandra Davis as Director of Strategic Programs and Chief of Staff.

The moves build on Vista Equity Partners' investment in Portside and Brandon Holden's appointment as CEO. Together, the four leaders will anchor Portside's next phase: Kim the product direction, Mogylatov the technology foundation, Ingram the financial discipline, and Davis the execution that connects them.

Portside is unifying its aviation software into a single platform, advancing an AI-enabled roadmap, and expanding its global go-to-market reach. Kim, Mogylatov, Ingram, and Davis will turn those priorities into a coordinated operating plan.

"This next stage of Portside is about focus and scale," said Holden. "We're going after a significant market opportunity, and capturing it takes the right technology foundation, clear product choices, disciplined investment, and consistent execution across the business. David, Roman, Jon, and Alexandra bring a powerful combination of deep Portside knowledge and outside experience to help us deliver on that."

Product strategy grounded in aviation operations

As Chief Product Officer, Kim brings more than 15 years building and scaling enterprise software. He'll lead Portside's global product strategy, strengthening the core systems customers depend on, connecting products and data more effectively, and advancing practical AI capabilities within aviation workflows.

A CTO who helped build the company

Mogylatov has been with Portside since day one, growing alongside the company as its technology, product portfolio, and global footprint expanded. As CTO, he'll lead engineering and technology strategy, with a focus on the scalable foundation Portside's next phase requires. He has also spearheaded the company's AI infrastructure - the technical backbone for AI's growing role across the platform.

Financial discipline for durable growth

As CFO, Ingram will lead financial strategy, planning, and operations globally, aligning investment with Portside's product, customer, and growth priorities while strengthening the systems needed to scale.

Turning decisions into progress

As Director of Strategic Programs and Chief of Staff, Davis will work closely with Holden and the leadership team to advance Portside's highest-priority initiatives across product, go-to-market, customer experience, and operations - with a focus on the coordination that turns decisions into results.

The appointments are part of a broader set of investments across Portside's technology, product, customer experience, and go-to-market organization. The company will share additional updates ahead of the 2026 NBAA Business Aviation Convention & Exhibition (BACE), October 20–22 in Las Vegas.

Portside Announces New Investment from Vista Equity Partners and Names Brandon Holden as Next Chief Executive Officer

SAN FRANCISCO, [March 05, 2026] – Portside, a leading provider of modern, cloud-based software solutions for global aviation, today announced a new investment from Vista Equity Partners ("Vista"), a global technology investor that specializes in enterprise software. The investment will accelerate platform integration, advance Portside's AI-enabled roadmap and further scale its global go-to-market capabilities. Current investor Insight Partners will remain a significant shareholder in Portside.

Portside simultaneously announced that Brandon Holden will be appointed Chief Executive Officer to lead the company’s next phase of growth. Holden succeeds Alek Vernitsky, Co-Founder of Portside, who will continue to serve Portside as a Strategic Advisor, focusing on product vision, AI innovation and customer engagement, as well as a member of the company’s Board of Directors.

Holden joins Portside with over two decades of experience leading and scaling high-growth businesses. He most recently served as Chief Executive Officer of Eptura, where he led the integration of multiple acquisitions into a unified global platform, driving operational discipline and go-to-market transformation. He also previously held senior leadership roles at LogicMonitor, Accruent and Forcepoint.

“Portside powers some of the most critical workflows in global aviation, spanning scheduling, safety and compliance, owner support and leasing," said Holden. "Our opportunity now is to extend that leadership by delivering an even more unified and intelligent platform that connects the entire operational lifecycle. This next chapter is about scaling what we've built and elevating it to define the category globally."

"Building Portside alongside co-founder Alek Strygin from the ground up and watching it become the platform that the world's leading aviation operators depend on has been the privilege of my career," said Vernitsky. "Brandon’s experience and focus on operational rigor make him exactly the right leader to take the company to an even higher altitude at this important stage. I’m proud of what we’ve accomplished and excited to work with Brandon and our amazing team as we continue our efforts to provide our customers with the industry’s most modern and comprehensive platform across the full spectrum of aviation.”

Since Vista's initial investment in 2024, Portside has strengthened its position as a leading cloud-native platform for business aviation, regional commercial airlines and aircraft leasing and finance. Now, with deepened investment from Vista, the company is entering an ambitious next phase — one centered on defining the global standard for modern aviation software. This includes continued development of Portside Horizon, its cloud-based flight management system, as well as expanded customer success and go-to-market capabilities designed to deliver seamless efficiency, enhanced decision-making and broader operational control for operators, airlines and lessors worldwide.

"We’ve had a front-row seat to Portside's disciplined early growth and the burgeoning opportunity to scale its platform across every corner of aviation software, a market that is both large and underpenetrated," said Rachel Arnold, Co-Head of Vista's Endeavor Fund and Senior Managing Director. "We are pleased to deepen our partnership with Portside to build on this momentum and enable the company’s ambitious expansion strategy."

"Portside's platform has been purpose-built to meet the operational demands its customers face across many aspects of their business," said Ben Benson, Managing Director at Vista Equity Partners. "This investment is about deepening those capabilities and helping to accelerate an AI-enabled roadmap that reflects the real demands of global aviation."

Terms of the transaction were not disclosed. Lowenstein Sandler LLP served as legal counsel to Portside. Kirkland & Ellis LLP served as legal counsel to Vista.
