Anthony Kappus joins Upwork as COO, effective September 2, to lead a team spanning legal, information security, payments & trust, customer support, and communications. Kappus brings significant operational expertise and marketplace experience from more than a decade spent at Redfin, where he led digital revenue, Redfin’s fastest-growing and most profitable business segment, along with corporate development and legal. He was instrumental in every chapter at the company over that decade, leading a diverse array of functions and teams.

“The breadth of Upwork’s mission and vision was clear from the moment I first met with Hayden and the team,” said Kappus. “Upwork is at the vanguard of how AI is transforming knowledge work. I’m thrilled to help scale Upwork’s global marketplace to both an expanding range of clients, from large enterprises to small businesses, and talented professionals around the world.”

Andrew Rabinovich’s expanded role as CTO, now leading engineering and IT alongside AI and machine learning efforts, reflects Upwork’s evolution into a truly AI-native platform and company, which is enhancing value for customers and catalyzing the company’s growth. Since joining Upwork in late 2023 as part of its acquisition of Headroom, Rabinovich has overseen the development and evolution of Uma™, Upwork’s mindful AI, into an always-on AI work agent, as well as custom domain-specific AI models tuned on Upwork’s proprietary data to deliver better work outcomes for both clients and talent. In 2025, newly-released AI and customer experience enhancements are contributing a more than $80 million lift in gross services volume (GSV) for the company.

“Today, thanks to our top-tier AI and engineering team’s rapid innovation, AI is at the core of nearly everything new that Upwork builds for our customers,” said Rabinovich. “Upwork has become an AI company, but we’re still in the early days of our roadmap for human-centered AI, and we have so much more to deliver in the coming quarters and years.”
