Williams will once again have a title sponsor in Formula 1 after signing a multi-year deal with Australian software company Atlassian.

The last time Williams had a title sponsor was in 2019 with ROKiT, but that deal ended in a legal dispute after the COVID-19 pandemic delayed the 2020 season.

However, the news partnership has been describe as the biggest sponsorship agreement in the team’s 48-year history and marks an important step in Williams’ push to become more competitive.

Atlassian, which develops software for project management, collaboration, and development, will also serve as Williams’ official technology partner and official collaboration software partner. This means the company’s expertise could help improve the team’s operations and efficiency, in addition to providing financial support.

The FW47, the car that Alex Albon and new signing Carlos Sainz will drive in 2025, will feature Atlassian’s branding in a prominent position. The company’s logo will also appear on the drivers’ race suits, team clothing, and throughout the team’s trackside and factory environments.

Williams will first reveal its 2025 car in a special design at Silverstone on Friday, before showcasing its full-season livery at the O2 in London on February 18.

Team principal James Vowles said: "I am delighted to welcome Atlassian into Formula 1 and our evolution into Atlassian Williams Racing.

"Attracting a title partnership of this size and significance is a momentous day in our team’s illustrious history and a major milestone in our comeback transformation.

"We are putting in place all the right ingredients to get this team back to the front of the grid, and in Atlassian we have a partner that through its technology and tools will help unleash our full potential by improving teamwork and collaboration right across the organisation.

"Our values and ambition align perfectly, and I’m excited about what we can achieve together."

Mike Cannon-Brookes, Atlassian CEO added: "Formula 1 is the ultimate team sport. It's where engineers, developers, commercial teams, pit crews and countless others work together in real-time at incredible speeds to race for a podium finish.

"Atlassian shares Williams' deep belief in the power of teamwork. We know that when great teams have the right tools and practices, they can achieve things that would be impossible alone. 

"As one of the first global technology companies out of Australia, we understand what it's like to have passion, drive and the belief that you're building something great.

"This team has been through a remarkable transformation, and I believe Atlassian Williams Racing has all the foundations for a renewed era of greatness."
