EtaKor, an AI-native measurement solutions company, today announced the appointment of Donald “Donnie” Williams as Executive Advisor and Chief Strategy Officer, effective immediately.
EtaKor helps marketing and sales leaders engineer profitable growth by combining causal measurement, AI-driven optimization, and continuous experimentation to deliver true incrementality. The company’s proprietary, uncertainty-aware models move organizations beyond historical reporting toward forward-looking, self-correcting AI-based decisioning, connecting investment directly to incremental revenue and profit.
“We are thrilled to welcome Donnie to EtaKor at this pivotal stage of our growth,” said Dr. Ramendra (Ram) Singh, Founder and CEO, EtaKor. “His deep experience scaling commerce, digital, and growth capabilities for leading brands and agencies is exactly what we need as we bring our causal-intelligence platform to market leaders who are demanding a better way to measure and deliver growth.”
Williams brings extensive leadership experience across digital marketing, creative/content, commerce, and enterprise strategy. He most recently served as Chief Marketing Officer at Lamark. Previously, as Chief Digital and Strategy Officer for Horizon Media’s affiliate businesses, he oversaw the firm’s technical operations, performance marketing, content, creative, and commerce capabilities. A serial entrepreneur and board advisor, Williams co-founded Night Market, a commerce agency bridging data and experience to deliver retail growth. He also holds board and advisory roles at several growth-stage companies spanning advertising technology and consumer health hardware.
“The future of growth belongs to organizations that can prove, not just report, the value of every dollar they invest,” said Williams. “EtaKor has built something genuinely differentiated – a platform that turns marketing complexity into confident, defensible decisions. I’m excited to help scale that capability to the leaders and brands that need it, and to work alongside Ram and Peeyush, whose vision and technical depth are extraordinary.”
EtaKor was founded in 2026 and is headquartered in Chicago, IL. The company’s agentic AI platform applies advanced marketing mix modeling, causal inference, and incrementality measurement across creative analytics, creative optimization, CTV and retail measurement, and cross-channel halo effects.
“Donnie’s commercial and strategic expertise is an exceptional complement to our technical foundation,” said Dr. Peeyush Sahay, Co-Founder of EtaKor. “As we expand the reach of our causal-intelligence platform, his ability to translate advanced measurement into real business outcomes for marketing and sales leaders will be invaluable. We’re excited about what we’ll build together.”
In his new capacity, Williams will focus on expanding EtaKor’s enterprise footprint, deepening strategic partnerships, and shaping the company’s market positioning as demand grows for AI-native, incrementality-focused measurement and optimization.
