SeaGil acquisition broadens Portside portfolio
The move brings BART scheduling software products within Portside's flight department offering alongside Owner Portal, Optimiser and ExpensePulse.

San Francisco-based cloud-based operating systems developer Portside has acquired SeaGil Software Company and its BART scheduling software product suite. Portside's investment signifies another step the company is taking to expand a product line that supports business, private and government aviation flight departments.

The investment will support the continued growth of Portside's customer base of Part 135 and Part 91 flight departments. After acquiring Professional Flight Management (PFM) in July of last year, Portside is looking to provide the business aviation market with a range of scheduling solutions. The two scheduling software acquisitions, PFM and BART, serve different market needs and have their own unique competitive advantages.

“Delivering mobile-first scheduling solutions is one of the many ways BART products work to increase accessibility as well as efficiencies for flight departments,” says Portside CEO Alek Vernitsky. “We are continuing to make strategic investments in scheduling solutions that can build on our core Portside products including the Owner Portal, Optimiser, ExpensePulse and others, further expanding the tools we offer to flight departments globally. SeaGil delivers a distinct product and will be complementary to our existing Portside and PFM offerings, further expanding our capabilities to best meet the needs of commercial and private operators alike.”

The BART product suite was first introduced in 1986. Over the last few years, SeaGil has rapidly expanded its customer base, supporting hundreds of operators, over 6,000 aircraft and well over 15,000 crew members globally.

“Brad and the team have worked hard to serve their customers for over 35 years,” says SeaGil CEO Kimberly Tilford. “Portside's investment is a validation of our proven growth strategy and product capabilities. The team will remain focused on driving the best outcomes for our customers.”

Following the completion of the acquisition, SeaGil will continue to operate as it does today with a distinct brand, identity and product focus. Portside's investment will enable BART to accelerate product development, complete additional integrations and enhance its customer support capabilities.
