Yun-Fang Juan is General Partner at Brighter Capital, Venture Partner and Senior Technical Advisor at Leadout Capital, Early Stage Investor focusing on Pre Product Market Fit.nI am an entrepreneur, software engineer and investor.nI am a product person. I have been building many different kinds of software products including web search (2001-2006) , targeted ads (2006-2011), e-commerce(2013), fintech(2014-2015), bioinformatics (2016-2019) in my 20 years of software engineering career. My current project is a robotic dumpling shop (zumplings.com-- closed due to COVID ). It's nice to make a different kind of product. But iteration, persistence and attention to details is still the key. I would say after 12 months development, my current robot made dumplings are pretty close to the hand-rolled ones.nI am also a fairly prolific angel investor. I think angel investing is a good way to pump money directly into the economy vs buying/selling in the public market. I also get to know different industries and different people through the process. Most of these investments are still illiquid but I am confident I make money. Notable investments include Iterable, MatterPort and Envoy. I invested in them at the angel/seed stage while their valuation is sub-$10M. They are now all over $200M in valuation.nI worked for Facebook from 2006-2011 starting as one of the founding engineers of Facebook Ads, which grew from scratch to a multi-billion dollar business in less than 3 years. I also started the coefficient project inside Facebook, developing the infrastructure and algorithms to characterize the friend and preference relationships on Facebook’s gigantic social graph. The system we developed served 1 million+ QPS and held billions of relationship metrics for real-time access with just a few hundred machines. Prior to Facebook, I worked for Yahoo! For 6 years on web search, data mining and ab testing framework.nI graduated with a BS in electrical engineering from National Taiwan University and a MS in operations research from UC Berkeley. I have filed 10+ patents on internet measurements, social ads and online friendships.
