How Bear Flag Robotics has built the technology & services to scale

The increasing adoption of autonomy, and more specifically robotics, is truly exciting. Robotics are already integral in our lives, from the manufacturing of our cars to the amazing logistics of getting any product on Amazon to our doorstep within two days. But this is just the tip of the iceberg. The most prominent application is in autonomous driving, but there is incredible innovation across many different sectors. In the past year we’ve been blown away by companies building robots in farming, home building, excavation, warehouse logistics, industrial inspection…


Paul Graham recently wrote an excellent essay on independent thinking. A topic I’ve thought a lot about is the key differences between early stage entrepreneurs vs. successful big company managers. They require distinctively different skill sets, the most stark of which is the importance of independent thinking. Having spent 5 years at a corporate behemoth, 2 years consulting for a variety of corporate behemoths, and now 6 years in venture capital, the correlation of independent thinking with success in different kinds of organizations is a fascinating topic.

For large organizations, the importance of large-scale execution and leadership often takes precedence…


Working from home is great but it has become very clear that there are no boundaries between home and work. As I adjusted to what would become the 2020 routine, I was privileged to manage my work schedule so that I could play with my kids intermittently throughout the day, have dinner with them, and then tuck them in around 9pm. That created a relatively short work day, so I’d sit down in front of my computer around 9–10pm and then get back to work until 1–2am. I’d also default to working on the weekends when the kids were napping/sleeping…


I wrote in April about the potential migration from dense urban centers to suburbia. It’s fascinating to see how much has changed in 3 months. Anecdotally, I’ve had several very close friends move out of Manhattan — their dominant reason driven by the need for more space for kids and for working at home. Several other close friends have moved or are actively looking to move from SF into surrounding Bay Area communities. …


D20 Capital leads StructionSite’s $7M Series A financing

The good old days of paper maps and arguing over route selection (Photo: Shutterstock)

There are many aspects of life for which we wonder how we used to get by before technology completely changed the way we do things. Paper maps are a prime example. Even in college, I was driving with a paper map in one hand, steering wheel in the other, trying to figure out at 70 miles per hour which exit to get off of. We’d also sit there and debate which route would be the fastest based on pure instinct of traffic patterns. Mobile and location technologies, coupled with large scale data…

These are the cities I have lived in, in chronological order, and their respective populations. I grew up in the small college town of Blacksburg in the Blue Ridge mountains of Virginia. I spent my teenage years and most of my twenties in Seoul, a sprawling, high tech metropolis, with four years wedged in between at the University of Illinois in the rural cornfields of Illinois. I then spent the first half of my thirties in…


John Krasinski’s ‘Some Good News’

It’s a difficult time to be optimistic. There is a lot of suffering, fear, and despair that is prevalent in the world due to the common enemy that is an invisible virus. For the talking heads, twitter pundits, and even the serious strategists, it’s much easier to riff on scary infection scenarios and gloomy economic forecasts. Despite being an eternal optimist, even I’m in agreement that it’s prudent to be preparing for a prolonged crisis. But for all of these reasons, I have extreme appreciation for those trying to bring hope and optimism to the world. John Krasinski’s Some Good…


Last month, I started a new role as a General Partner at D20 Capital, an investment firm based in San Francisco that is backed by Doosan Group. D20’s mandate is to invest in innovation that is revolutionizing traditional industries, starting with construction and manufacturing — industries where Doosan has a strong global presence via affiliates like Bobcat and Doosan Infracore.

D20 Capital is yet another bold bet for Doosan. Enabled by support from both top management and the founding family, hard earned capital is being committed from a capital intensive business. D20’s independent mandate and streamlined decision-making processes represent Doosan’s…


In the world of technology, everything moves at an unbelievable pace. 10 years ago, I speculated that ‘in the future’ we might be watching HD video on our phone while browsing the internet, all on our mobile device…and that we might have mobile devices where one screen unfolds into two — I even wrote a patent on it! Executives rolled their eyes, as back then it seemed like science fiction. Look where we are now!

Foldable Mobile Device— Patent filed in 2009 by yours truly and Samsung’s newest product announcement

In 2009, I was a product manager at Samsung Electronics, planning and managing the development cycles of Samsung’s System-on-Chip (SoC) processors that would power the…


Beeswax pitch deck slide 1

The typical VC reaction to an ‘ad tech’ deal these days is “sorry, we don’t invest in ad tech.” I almost had the same reaction when I came across Beeswax. But as we dug deeper into the team, company, and industry we learned something: this wasn’t just another adtech company. Beeswax is a SaaS company providing tools for marketers to address four key trends in programmatic advertising:

“Would a hedge fund use Schwab to buy equities?”

This from the Beeswax pitch deck jumped off the page at me. Of course they wouldn’t. A hedge fund’s bread and butter is creating…
