I am invested in startups in Boston, NYC, LA, SF, and Chicago.  Let’s connect.


Invested in 30+ founders, over half of those in the last 3(ish) years, with two early exits (one IPO).

I HUSTLE TO FIND FOUNDERS who I believe can create great companies in big markets, and when I find them I am decisive in making an investment decision.  And exuberantly helpful with introductions and support.

BORN IN JAPAN, I am the daughter of a US Air Force Officer and was raised in five states across the country and five cities in the State of California alone.  Growing up I joined every team sport I could ride my bike to, including baton twirling, volleyball, cheerleading, cross-country running, golf, tennis, swimming, rugby and softball (my favorite, for which I was named league MVP as a fastball pitcher).  Almost all of those teams were on military bases and made up of kids from an extremely broad mix of backgrounds.  For most of those teams I was elected Captain.  Moving in and out of new towns and on and off of new teams so much, I got good at seeing beyond the obvious and judging ability, character, motivations, hustle and will.  The resourceful, intangible assets.  That is why once I have done my diligence, I am decisive in backing founders.  Often with their first outside check.

At the University of New Hampshire, I was an instructor and lead climber for Advanced RockClimbing.  After UNH, I moved to New York City without a job or knowing a single person there.  One of the boldest and most affirming experiences of my life.  I went to Georgetown University Law School, where I was elected Editor in Chief of my law journal, wrote an Article that was cited by the Supreme Court of California and received a coveted American Jurisprudence Award.  Years later I attended MIT Sloan, which fed a growing startup bug.

I HAVE 20+ YEARS of operational start-up and scaling, financing, management and strategy experience.  I was instrumental in building a world-class competitor in a cut-throat asset management market, and I have also been the CoFounder of a fintech startup.  I was CoFounder and a Managing Partner of a digital asset/blockchain company that launched four business lines in less than a year.  Before that I was a Partner for over 13 years at one of the world’s leading hedge funds. Its “all hands on deck” entrepreneurial culture drove high growth in all key areas and significant scaling of operations. As a member of the senior management team, I played key strategic roles on distressed debt investment teams, managed the outside Board of Directors, handled HR matters, and launched projects on risk, valuation, operations, governance and cybersecurity.  I built the legal, regulatory and compliance teams from scratch to a team of 10+, and directed everything from investor negotiations to investment transactions, and handled everything from high stakes litigation to media affairs.

I ALSO FOUNDED A SUCCESSFUL NONPROFIT START-UP.  Named a #SOGOOD Award Finalist by BostInno and featured in the Boston Globe for its innovative model, SheGives is a platform to introduce donors to a portfolio of highly vetted, high impact nonprofits.  SheGives founders are a cohort of Boston’s most accomplished women in finance, healthcare, biotechnology, venture capital and technology who together have made grants of almost $1m.  SheGives.  Smart Women.  Smart Giving.

I believe in service to others, and 10% of my profits from each investment goes to nonprofits, including SheGives.
