Veteran Silicon Valley Angel Investor Yun-Fang Juan Invests in Greenfield Robotics

Greenfield Robotics is pleased to announce that Yun-Fang Juan, a Silicon Valley angel investor with more than 25 successful exits, has made an investment in the company. ​

She was an early employee at Facebook, and one of the founding engineers of Facebook Ads.  She single-handedly wrote the first version of the Facebook ad server which handles indexing and serving of self-serve and brand ads.  Yun-Fang also led the optimization team which applied machine learning to predict click-through rates. Under her technical leadership, Facebook Ads grew from scratch to a multi-billion dollar enterprise in three years. 
Yun-Fang has been an active investor on AngelList for many years; her syndicate has had 28 exits to-date.  Notable investments include Iterable, Matterport and Envoy, each with recent valuations exceeding $100M, and Reddit, which raised a round last year at a price of $3B.  
“I see another huge opportunity in Greenfield Robotics,” says Yun-Fang.  “This company is in the perfect time and place to apply machine vision to solve not just one, but two massive real-world problems- eliminating chemicals from our food and fighting climate change. 
“We are so proud to have Yun-Fang backing our company,” says Clint Bauer, CEO/Co-Founder of Greenfield Robotics.  “Yun-Fang brings a wealth of Silicon Valley wisdom and expertise. Through her technical network she is able to connect us with some of the best minds in machine learning, machine vision and robotics.  And her track record as an investor speaks for itself; it’s a world-class portfolio and we are ecstatic to have her as an angel investor.”
Greenfield Robotics is developing robots to replace chemicals in agriculture, and to enable large-scale implementation of carbon farming, a new system of farming that holds the promise of sequestering carbon in farmland on a global scale.
