The Kind of Product Leader Every Company Needs
"JK" runs world-class product teams that people want to be on. I have had the pleasure of working with him for the past two years and have experienced first hand his tremendous impact on the company, products, and people around him. JK and his team have continuously gone above and beyond to deliver tremendous outcomes, which is directly attributable to the team, structure, processes, and culture that he has created. He is customer obsessed, collaborative, and not afraid to "pick up a shovel" and get to work. Having worked alongside JK during this period of rapid AI adoption and change, he was the first to advocate for and integrate these tools into his and his team's workflows, enabling even higher quality outcomes more rapidly. JK is an invaluable asset to any team that he is a part of.
