Robert F. Smith is not done with aviation software.
Vista Equity Partners, the Austin, Texas-based private equity firm Smith founded in 2000, announced March 5 that it has made a new investment in Portside, a cloud-based software provider serving the global aviation industry. The move builds on Vista's initial stake in the company, which it first acquired in May 2024.
Financial terms were not disclosed.
Portside's platform covers the operational infrastructure airlines, charter operators and aircraft lessors depend on daily, from flight scheduling and crew management to safety compliance and owner support. The company employs more than 330 people across 40-plus countries and serves more than 1,300 enterprise customers worldwide.
The fresh capital is earmarked for three things: deeper platform integration, an expanded AI development roadmap and a broader global sales push.
Along with the investment announcement, Portside said it is bringing in a new chief executive. Brandon Holden, who previously led workplace management software firm Eptura, will take the top job. He succeeds Alek Vernitsky, the company's co-founder, who moves into a strategic adviser role and keeps his seat on the board.
"Portside powers some of the most critical workflows in global aviation," Holden said in a statement. "Our opportunity now is to extend that leadership by delivering an even more unified and intelligent platform that connects the entire operational lifecycle."
Vista's Endeavor Fund, which backs high-growth enterprise software companies, led the transaction. Rachel Arnold, co-head of the Endeavor Fund and a senior managing director at Vista, said the firm had watched Portside grow with discipline since the first investment and saw a large, underpenetrated market still ahead of it. Ben Benson, managing director at Vista, described the investment as being about deepening Portside's capabilities and pushing forward an AI roadmap that responds to real operational demands in aviation.
Insight Partners, which backed Portside before Vista came in, will remain a significant shareholder.
Smith built Vista over 25 years into one of the largest enterprise software investors in the world. The firm now manages more than $107 billion in assets across more than 90 portfolio companies. Forbes estimates his personal net worth at approximately $10.8 billion, making him one of the wealthiest African Americans in history.
Kirkland & Ellis advised Vista on the transaction. Lowenstein Sandler represented Portside.
