SAN DIEGO (April 30, 2026) – NASCAR San Diego announced today that Mattermost, the leading sovereign collaboration platform purpose-built for mission-critical operations, will serve as the naming rights sponsor of the Turn 11 suite structure during NASCAR San Diego Weekend presented by Anduril at Naval Base Coronado.
Situated at one of the most technical and action-packed sections of the 16-turn, 3.4-mile circuit, the newly branded Mattermost Suites will provide a premium hospitality experience with commanding views as drivers navigate the challenging Turn 11 complex. The Mattermost Suites will serve as a premier gathering space for partners, customers and invited guests to connect while taking in world-class racing at the first NASCAR event ever held on an active military base.
“Mattermost is an innovative company with deep roots in operational sovereignty and secure collaboration, making them a natural fit for this historic event at Naval Base Coronado,” said Amy Lupo, President of NASCAR San Diego. “The Mattermost Suites will offer an exceptional experience for guests while showcasing a brand that shares our commitment to precision, performance and teamwork. We’re proud to welcome Mattermost aboard for this historic weekend.”
Mattermost delivers secure, workflow-centric collaboration for the world’s most demanding operational environments. Built for national security, intelligence, public sector, and enterprise teams, it enables organizations to move fast, coordinate with precision, and maintain full operational control — even in disconnected, classified, or high-threat conditions — aligning seamlessly with the spirit of innovation and operational excellence that defines NASCAR San Diego Weekend.
“Mattermost was built for mission-critical operations where control, resilience, and speed determine outcomes,” said Leigh Dow, Chief Marketing Officer at Mattermost. “Naval Base Coronado represents the standard our customers operate at every day. This isn’t just a sponsorship — it’s a reflection of our commitment to the operators, missions, and environments that demand secure, sovereign coordination at scale. We’re proud to support a weekend that brings that standard to life and honors the Navy’s 250-year legacy of service to this nation.”
NASCAR San Diego Weekend presented by Anduril begins with Navy Community Day on Friday, June 19, 2026. Access that day will be open exclusively to members of the U.S. Navy stationed at Naval Base Coronado and a limited number of Coronado residents, culminating with the NASCAR CRAFTSMAN Truck Series race.
Ticket holders from the general public will be welcomed aboard June 20–21, 2026. The NASCAR O’Reilly Auto Parts Series will take center stage on Saturday, June 20, and the stars of the NASCAR Cup Series will compete in the Anduril 250 Race the Base on Sunday, June 21.
