Mosaic Insurance has promoted Yosha DeLong to the new position of global engagement officer and appointed industry veteran Brian Bonkoski as global head of cyber.

Ms DeLong, based in Chicago, has led Mosaic’s cyber business since the company’s launch in 2021, growing a global team of 32 specialists across the US, Canada, Bermuda, the UK, Germany and the United Arab Emirates. She will now oversee market engagement across all product lines, including distribution, client and broker relationships and digital business development.

“Yosha’s extensive experience and deep understanding of our products and global broker relationships will be key as she leads our market engagement efforts to drive profitable growth,” said Mark Wheeler, co-chief executive of Mosaic. “Her leadership in cyber has been integral to Mosaic’s success, and I’m confident she will excel in her critical new role.”

Ms DeLong added: “Engaging closely with our clients and partners has been a cornerstone of Mosaic’s strategy from day one. As we enter this new growth phase, I’m excited to help elevate our global impact with partners, brokers, clients and stakeholders, as well as collaborate with Brian on the continued expansion of our cyber line of business.”

Mr Bonkoski will assume his role on June 16. He brings two decades of underwriting and distribution leadership, having held senior positions at Chubb and AIG.

“Brian’s proven expertise in cyber and technology risk, and his market following, combined with his strategic vision, will be essential in strengthening our global franchise and delivering sustainable value,” said Toby Smith, CEO, Americas, at Mosaic.

Mr Bonkoski said: “I’m thrilled to join a dynamic, agile cyber insurance carrier that’s committed to becoming a market leader. I look forward to leading our mission of delivering innovative coverage and creative risk-management solutions that truly support and protect our policyholders.”
