“Daniel played a critical leadership role in helping us scale and successfully sell the Gen AI company Streamr to Magnite. He brings deep commercial expertise paired with a strong understanding of product and technology, enabling him to operate effectively end-to-end—from strategy through execution.

Post-acquisition, Daniel continued supporting Magnite, leading on complex, multinational, multi-party commercial initiatives, where he was exceptionally thorough, professional, and effective, including in his deal-making work with Wolt’s Retail Media Network (a DoorDash company) and major strategic brands and publishers.

He is highly consultative, adapts seamlessly across both early-stage and large matrixed organizations, and consistently brings clarity, rigor, and momentum to challenging commercial situations.”

“Daniel played a pivotal role in bringing GenAI creative and CTV capabilities to Wolt Ads at a key stage of our retail media growth. He operates comfortably from strategy through execution, aligning senior stakeholders and global teams to turn innovation into early live programs and revenue opportunities.

His leadership helped open new growth channels for our brands and merchants while laying the foundation to expand our offsite capabilities at scale. Beyond the results, he was a true pleasure to partner with — thoughtful, collaborative, and deeply committed to our shared success.

“The highest integrity, standards and degree of discipline necessary to deliver the transformative improvements and outsized impact we’ve needed at this company.”

“Daniel’s wealth of knowledge in digital media, tech and sales, coupled with his strategic thinking, was instrumental in developing our business strategy and implementing an effective sales process. His exceptional mentorship and dedication to helping businesses succeed make him an invaluable asset for any organization seeking growth and development.”

“Daniel Harrison’s expertise in client relationships is unparalleled, combining deep industry knowledge with an exceptional ability to understand and prioritize customer needs. His commitment to delivering results, coupled with his talent for clear communication and partnership-building, makes him an invaluable asset to any business seeking growth and success.”

“Daniel is one of the most genuine and well respected people I know in the industry. I have fond memories of working closely with him, strategizing on ways to bring the business forward, and pitching sophisticated ad technology (software with service) to global brands internationally.

Aside from being a pleasure to be around, I can attest to his professionalism, leadership and consultative sales skills. People value his digital experience, approach to delivering value on multiple levels and people buy from people. You want Daniel leading or advising your team, no question.”

“Daniel provides crucial advice and executive guidance to my business, as we’ve needed to evolve to meet changing markets and customer needs. Incredibly intelligent, thoughtful, cutting edge, outcomes driven, diligent and down to earth.

I’ve known him for many years — as an early stage employee, who quickly became a colleague, friend, and long-term trusted transformational strategic advisor.”

“Daniel brought GenAI creative and CTV innovation to our team at Wolt Ads, and together we took the initiative from concept through our first campaigns with leading brands across European markets.

What stood out was his ability to operate across every dimension of a complex, multi-market initiative, coordinating across our country teams, account managers, product, and creative, while keeping commercial momentum.

When we hit measurement challenges, he didn’t step back — he worked side by side with our team to solve and establish an early foundation for scaling across our business.

What I appreciate most about Daniel is his flexibility and ‘will to make things work.’

He’s a rare combination of strategic vision and hands-on commercial execution, and one of the most effective partners I’ve worked with.”
