Paul Sigaloff joins Mortar in global leadership role

September 3, 2025 9:51

Ooh Media’s former chief revenue and growth officer, Paul Sigaloff, has joined the leadership team at “independent, privacy-safe measurement platform”, Mortar.

Mortar is used by organisations in the FMCG, retail and automotive industries “to connect data systems including CRM, CDP, and advertising platforms”.

Sigaloff will be the platform’s chief customer officer. The industry veteran last worked as Ooh Media’s chief revenue and growth officer from May 2023 to the end of 2024, when he officially stepped down and was replaced by Mark Fairhurst. Ooh has since posted a strong H1 result, coinciding with the exit of outgoing CEO, Cathy O’Connor.

In June, Sigaloff announced on Linkedin he was “stepping into entrepreneurship” as the founder and CEO of Tolly Loans & Finance. He’ll continue to oversee the business.

In his new role with Mortar, Sigaloff is tasked with leading the platform’s global customer strategy and developing tools and services to support marketers.

“Paul has a proven ability to lead transformation and put customers at the centre of growth. His leadership will ensure that Mortar not only delivers powerful technology but also drives extraordinary outcomes for every customer we serve. This is a landmark appointment as we scale globally,” Mortar’s group chief executive officer, James Zipeure, said in a press release.

Before joining the out-of-home organisation, Sigaloff spent over a decade at Yahoo. While there, he was vice president (VP) and head of APAC for the business, and, before that, he was its VP and managing director for Australia, New Zealand, Southeast Asia and India.

When asked about his latest appointment, Sigaloff described the opportunity as “a privilege”.

“I’m thrilled to be joining Mortar AI at such an exciting time in its journey from start-up to scale-up,” he said in the same release.

“AI and emerging technology are rewriting the rules of marketing, and Mortar is uniquely positioned to help brands and agencies reimagine how they invest, grow, and create impact. It’s a privilege to be part of shaping that future with our clients globally.”

He begins his new job this week.
