Russ Fein, whose The Quantum Leap on Substack is both insightful and highly readable, gave a double shoutout to CEO Hilary Kaye and EVP Mike Kilroy in his year-end article, “Top Quantum Achievements of 2025.” Russ wrote:

“Hilary is the founder of HKA Marketing Communications and Mike is EVP. HKA focuses exclusively on the quantum industry, representing some of the key players in the space. Through them, I’ve had the pleasure of visiting Redmond to see Microsoft’s Majorana 1 release as well as Broomfield to see the unveiling ofQuantinuum’s H2, among other industry events. Formative events like those have provided a much deeper understanding of the industry for me. I am also grateful to them for including me in their Quantum Expert Forum. You can learn more about Hilary, Mike and HKA here.”
