Huynh's family were refugees from Vietnam. She attended prestigious Stanford University on a scholarship. She took time off her studies when there was a wild demand for skilled computer programmers, shortly before the dot-com-boom went bust. In 2000 she met Scott Hassan, another Stanford alumnus, and the pair married in December 2001.
Accounts as to which partner provided the primary income in the earliest years of their marriage differ, and became a matter of dispute during their long and acrimonious divorce, which Hassan initiated in 2013, and which was still in dispute in 2021.
Scott Hassan was the primary owner of Willow Garage, and its successor Suitable Technologies. The firm's primary product was a remote control robot, called a Beam, that was equipped with both tracks, for rolling around, a webcam, and speakers and a video display. A user who wanted to interact with individuals at a remote location would login to a remote beam, which would project his or her voice, and display his or her face, in real time, as the user sent it traveling to visit colleagues. While the idea of the beam was praised, this was not matched by sales - only 7,000 units were sold.
Huynh voiced concerns when Hassan tried to sell the company for $800,000, asserting it was worth much more. She voiced the concern that Hassan was so angry over the divorce he was disposing of assets he would be obliged to share with her for far less than they were actually worth. After she voiced her concerns Hassan resigned and turned the company over to a bankruptcy trustee. Financial commentators noted that Hassan was in the unusual situation of being both Suitable Technologies' primary debtor and its primary creditor. As its primary owner he was the primary debtor. On the other hand shell companies he also owned had provided the loans that financed its growth, so he could be said to owe that money to himself.
