How did you gravitate towards fintech in the first place?

MARK – I started as an undergrad in the heart of the recession. My mother is an immigrant and my father was stuck in an extremely cyclical business, so the downturn hit my family hard. Luckily, I was able to help over the years by working various jobs while in school. I decided to use a portion of my student loans to help them, knowing I was about to receive a signing bonus prior to starting my full-time job. However, I miscalculated the taxes on that bonus and found myself without enough capital to bridge between graduation and my first paycheck three months later. As I stood in line at a payday loan provider in Berkeley, reviewing the 40-60% APR on the 4-week loan I was about to withdraw, I knew there had to be a better way to serve this market. 

This led me to believe there was massive opportunity to revamp credit underwriting, earned wage access, and lending, to name a few areas. One of my goals in moving to VC is to facilitate the growth and success of these upstart businesses, so a kid in my situation five years from now doesn’t have to deal with similar pain points.

What themes within fintech do you find the most compelling?

MARK – With so many areas ripe for technological innovation, my answer is usually a moving target. That said, I do find increasing automation, transparency, and efficiency within back office functions (e.g., treasury, accounts payable, accounting, etc), earned wage access enablement, neobank proliferation, disrupting the traditional credit underwriting model, increasing sensitivity around payments costs to ISVs, SMBs as a technologically underserved category, and burgeoning innovation in emerging markets intriguing.
