Portside, a provider of cloud-based software solutions for the global aviation industry, announced a new investment from Vista Equity Partners to accelerate platform integration, advance its AI-enabled product roadmap, and expand its global go-to-market capabilities. Existing investor Insight Partners will remain a significant shareholder in the company.
At the same time, Portside announced that Brandon Holden will become the company’s next chief executive officer, succeeding co-founder Alek Vernitsky. Vernitsky will continue supporting the company as a strategic advisor focused on product vision, AI innovation, and customer engagement, while also remaining on Portside’s board of directors.
Holden brings more than two decades of experience scaling high-growth technology companies. He most recently served as the chief executive officer of Eptura, where he oversaw integrating multiple acquisitions into a unified global platform and helped drive operational and go-to-market transformation. Earlier in his career, Holden held senior leadership roles at LogicMonitor, Accruent, and Forcepoint.
The company said the new investment will support its next phase of expansion as it works to further develop Portside Horizon, its cloud-based flight management system, while expanding customer success operations and global sales capabilities. The company’s platform supports operational workflows across the aviation industry, including scheduling, safety and compliance, owner support, and aircraft leasing management.
Since Vista’s initial investment in 2024, Portside has expanded its position as a cloud-native aviation software platform serving business aviation, regional airlines, and aircraft leasing and finance organizations. With the additional capital, the company plans to scale its AI-driven capabilities and broaden its reach across aviation operators, airlines, and lessors.
Portside currently employs more than 330 professionals across over 40 countries and serves more than 1,300 enterprise customers worldwide.
