What I do
I joined 25madison in February 2022 to invest in early stage companies for the 25madison Ventures Fund. I’m looking for obsessive founders who are building products that customers are obsessed with.
About Me
I studied Molecular Biology at Yale, but I found my true passion in tech. Before 25madison, I was an early stage investor at Headline (fka e.ventures) in San Francisco, where I led investments in primarily healthcare, consumer, and SaaS. I started my career at Google and have also worked at Clover Health, Rainfall Ventures, and TikTok, where I was the 10th US employee.
I was born in Taiwan, but I grew up in the US. I'm very passionate about protecting democracy, freedom of speech, and human rights.
What I do: I love finding new ways to better serve customers by solving unmet needs. I enjoy helping our incubations figure out what to create first, acquire their first set of users, and build a monetization strategy. I'm especially passionate about Financial Technology and products that expand economic opportunity.
About me: I'm a proud New Jersey native who has spent time living in Baltimore, San Francisco, and Boston. I traveled and worked in India & Nigeria and draw energy from seeing the positive impact new technology can have on people's lives. I'm a die-hard ice hockey fan (go Devils!), American politics nerd, and enthusiastic debater of issues people care about.
What I Do
I am fascinated by how the next set of category-defining companies are emerging against rapidly changing consumer demographics, shifting generational mindsets, and a continually evolving digital environment. At 25madison, I spend my time identifying, testing, and iterating new ventures, conducting diligence on investment opportunities, and providing support to portfolio companies.
About Me
I was born in Nashville, TN and have lived in Louisiana, Pennsylvania, and Texas. In my free time, I enjoy running, playing and watching tennis (go Federer and Serena!), yoga, cooking, traveling, and eating great food.
At 25madison, I work with our team and our portfolio companies to build great businesses. As a lifelong entrepreneur, I've seen what works and what doesn’t work, over and over again. Now, I help entrepreneurs and our team avoid many of the pitfalls I’ve seen and experienced. I also work with our Board and Founders to set our overall strategy and make sure that the areas where we focus have positive impact and can generate great returns.
I’m a lifelong learner and entrepreneur. I've built businesses that have become public companies (twice), have been sold to large corporations and some that have been less successful. I've founded companies in media, telecommunications and business services, but now, I'm thinking most about business opportunities that tackle loneliness, aging, the future of work, preparedness and healthy living.
I’m focused on building 25madison into a unique operating platform that creates successful businesses. I work on developing our team and capabilities. I enjoy meeting with founders and growing our incubated startups. My goal is to help our companies get organized, clarify priorities, and scale quickly.
I grew up outside of Boston and spent my professional career in NYC and Asia. I love to sail, ski and fish, particularly with my family, and read history.
Justine is a partner in 25madison Ventures, an early-stage venture capital fund that invests in Pre-Seed, Seed, and Series A opportunities. She is Chief Operating Officer of 25madison Studio, a venture studio that partners with founders at the earliest stage of their journey to build break out companies. Prior to 25madison, she helped build Citi Bike and its affiliate operations across the country into the largest bike-sharing company in North America. After leading the sale of the company to Lyft in 2018, she worked on Lyft’s expansion into electric bikes and scooters.
I’m a lifelong New Yorker, passionate about improving cities and urban mobility. I love meeting entrepreneurs, going deep on new ideas and businesses, and my daily Citi Bike commute.
