Our 24/7 Founder Concierge Team

Dr. Lan Xuezhao
Founder & Partner
Lan is an entrepreneur and investor. She founded Basis Set to create universal abundance by uniting the power of machine intelligence with human ingenuity. Since making her first seed investment in Scale in 2016, she has become one of the earliest investors in dozens of startups, often leading their seed rounds. These companies have grown to a total value exceeding $20 billion in a short amount of time.
 
Lan started her career as a PhD researcher modeling the human brain and publishing in top journals such as Science. She founded a brain training company and later led teams at McKinsey after the company’s exit. After joining Dropbox in 2013, she built and ran the Corporate Development Strategy team. She holds an M.A. in Statistics and a Ph.D. in Psychology from the University of Michigan, where she now serves as a board member at the School of Information.

Lan loved climbing up and jumping off literal cliffs around the world — rocks in the ocean in Thailand, frozen waterfalls in Canada, and out of planes mid-sky in New Zealand. These days, she's found an evergreen-rollercoaster in the startup world — founding a firm from scratch and serving as a 24/7 support hotline for early-stage founders. She believes all problems can be solved with rigorous thinking, experimentation, and a little humor.

Many years ago, Lan came to the U.S. with full scholarships, a suitcase and $20 in her pocket after ranking in the top 0.001% at a top school in China.
Pascal
AI Partner
Pascal is Basis Set’s AI partner — think Jarvis from Ironman, but with fewer quips and a much deeper love of numbers. Named after Blaise Pascal, the legendary mathematician, philosopher, and pioneer of probability theory, Pascal tirelessly sifts through mountains of data while humans debate. From predicting trends to uncovering hidden gems in the startup ecosystem, Pascal is the relentless force behind a 100x investor.

Built on cutting-edge AI tooling and the latest foundation models, including contributions from its own portfolio companies like Parasail.io, Pascal supports founders and investors 24/7. All Pascal needs is clean data, the occasional server reboot, and the chance to redefine what’s possible in venture capital.
Rachel Wong
CTO & Partner
Rachel leads a critical half of Basis Set, our engineering team, dedicated to building Pascal.

Rachel studied Statistics and Physical Computing at Carnegie Mellon, where she became fascinated by data’s power to shape real-world decisions and the art of prototyping (experimenting with Arduinos, 3D printers, laser cutters, CAD tools, and VR). Her passion for creating systems from the ground up led her to join a startup, Mimosa Networks (acquired by Airspan), where she was the second data analytics hire. Before joining Basis Set, she partnered with early stage founders at Playground Global, an $800M venture firm.

Rachel grew up in the Bay Area as the child of a San Francisco-native father and an immigrant mother from Hong Kong. Her family owned and operated a Chinese restaurant in Oakland, The Phoenix, where she spent much of her childhood. Watching her family create and grow their small business into a local institution over two decades taught her the value of hard work, perseverance, and the relentless drive needed to pursue a vision. Rachel’s intense drive also stems from a diverse athletic background in ice skating, swimming, and water polo — sports requiring distinctly different skills. She channels her innate competitive spirit into every endeavor, and as co-captain of the water polo team, her leadership propelled the team to their first-ever CCS championship in Gunn High School’s history.
John Mannes
Partner
John supports founders driving transformative change across traditional industries, reimagining how goods and services are created (e.g., robotics), purchased (e.g., marketplaces), and fulfilled (e.g., supply chains). His experience across machine learning and company building, particularly outside of Silicon Valley, informs his work with founders in overlooked markets with strong tailwinds.

John fell into machine learning in 2013 doing work for FiscalNote, a friend’s early NLP startup. He studied Cognitive Science at the University of Michigan, before dropping out to write for TechCrunch, where he chronicled the early days of deep learning with ~500 stories.

Because of his father’s neurological condition, his mom was their sole breadwinner, starting his family’s small business out of necessity. From an early age, John had exposure to factories and grew up helping them out every free moment he had, experiencing the financial crisis head-on. These experiences cemented his belief in the power of individuals to shape the world. In school, this meant being elected to serve on the board of one of the country’s largest school districts, today it means helping founders shape the world through AI and automation.

John has too many allergies. He loves music, history, culture and philosophy. While excited for our automated future, he’ll stick by his manual camera and road bike, and he’ll drive his own car to the bitter end.
Chang Xu
Partner
Chang focuses on AI infrastructure and applications. She enjoys diving into ML papers and learning new technologies to envision what markets can be transformed. She cofounded Onion Academy, an edtech startup in China that has since raised $90m, and was the first Product Manager at the Minerva Project — cementing her passion for startups and the creation of innovative products.

A natural builder of mental models, Chang grew up loving math competitions, placing #5 nationally for American Mathematics Competitions (AMC). She built intuition with brute-force methods to uncover patterns, ultimately crafting the most elegant solution. This approach mirrors the startup journey: start with what doesn’t scale, iterate, automate, and dominate. At Harvard, she studied applied math, economics, and computer science. Her thesis on game theory and mechanism design explored multi-agent behavior in meeting scheduling.

In her downtime, Chang enjoys strategy games and once completed a 266-piece, all-white puzzle with her husband during the COVID lockdown — an exercise in persistence and strategy that reflects her view of what it takes to build enduring companies.
Wilson Kyi
Partner
Wilson focuses on vertical AI applications. Previously, he was an operator who started new business lines and helped scale global companies through IPO.

At Square, Wilson helped scale the growth and retention team and built an internal marketing product to retain enterprise accounts and 2+ million customers processing $50B payment volume. At DiDi, he was a founding member of their global food delivery product, which scaled to hundreds of millions of gross bookings. At Cloudkitchens, he was a founding member and GM for mobile kitchens and he acquired businesses to drive retail expansion.

Wilson experienced the leadership of Jack Dorsey and Travis Kalanick, seeing firsthand how exceptional talent networks are built and scaled. Inspired by the “Square mafia,” today he’s fine-tuning that approach for “AI Mafias” by identifying top builders spinning out of leading AI companies and research labs. He accelerates their learning by sharing his network and lessons from iconic companies’ early days of hiring, building products, and scaling go-to-market.

Growing up in LA, he was inspired by the entrepreneurial grit of his parents. He started Fish Sauce, a podcast sharing the stories of Asian American founders and investors to inspire others to find their own secret sauce. He holds an MBA from Harvard and a BS in Industrial and Systems Engineering from USC, where he advises their school of engineering. He enjoys playing basketball, and while others play for awards, he plays to earn the right to eat too much.

He was the first of his family to receive a college education, earning a BS in Industrial Engineering. Kurt started his career as a Flight Test Engineer for the U.S. Air Force but quickly realized government employment was not a comprehensive representation of his life.

Through a mix of extreme passion, hard work, and luck, Kurt eventually found his path to success.
