I'm Yumi Alyssa Willems Kimura (yes, it’s a long name!). Depending on where you search, you’ll find me as Yumi Alyssa Kimura in Japan and Yumi Willems or Yumi Kimura in the U.S.—a result of my love for all my names and my trial-and-error approach to personal SEO. I grew up in an international family with roots in Japan, China, and Eastern Europe and have been based in the U.S. since 2013.

​

At 18, I took a leap into entrepreneurship, moving to Shanghai without local connections or language skills. There, I co-founded a translation, tour guiding, and real estate business with my schoolmates. During college, I interned at a Japanese immigration law firm, where I saw firsthand the limited career growth opportunities for women in law. After earning my degree from Kwansei Gakuin University in Japan, I transitioned into HR consulting at Hays and later became a partner at Spinnaker Partners, assisting U.S. companies with venture capital fundraising and M&A.

​

Seeking further growth, I moved to the U.S. and played a pivotal role in establishing Meitu Japan, leading to its $4.5 billion IPO in 2016. Meitu, a leading beauty and photo-editing app company, has amassed over 1 billion downloads globally. Similar to how TikTok operates under ByteDance, Meitu Japan functioned as the regional arm, adapting Meitu’s technology for the Japanese market and expanding its reach in Asia’s digital and social media landscape.

Recognized for my contributions to tech, I secured an O-1A visa (for extraordinary ability in business) and went on to found Lead Tech, Inc. (LEAD) in the U.S. To deepen my expertise, I pursued evening courses in HR Management and People Analytics at Wharton and Product Management and Data Science at UC Berkeley (check out my GitHub).

Currently, while running LEAD, I'm also pursuing a Master of Science in Information and Knowledge Strategy (IKNS) at Columbia University. My work has been featured by Columbia IKNS, where I shared how my information and knowledge strategy shaped my approach to enterprise knowledge management. I also published my first academic paper, "The Organizational Intelligence Loop: A Socio-Technical Framework for Adaptive Enterprise AI Adoption," which documents seven years of work building LEAD and insights from my post-Meitu career, and proposes a practical engineering layer for enterprise AI. It describes a governed runtime context system built from behavioral and organizational network signals that encodes expertise, trust and ownership, decision rights, and workflow constraints so agents can operate with real organizational context, stay within permissions, and produce auditable outputs.

I've been invited to guest lecture at Washington University's Olin Business School, where I led a session on Human Resource Management in Startups, and to speak on enterprise AI design, adoption, and digital transformation at Wharton, other universities, and industry conferences. Along the way, I've also received invitations to serve on public company boards and contribute as a business commentator for Japanese TV channels. While these opportunities were flattering, I chose to decline them—running a startup in its growth phase demands singular focus, and I wasn't willing to dilute my attention from building LEAD.​​

At LEAD, we specialize in operational efficiency and knowledge management within enterprises. Our flagship product, LEAD.bot, is a relationship intelligence platform that leverages AI, behavioral science, and Organizational Network Analysis (ONA) to optimize enterprise collaboration and decision-making.
