In 2007, Tim started touring the USA giving presentations about a new music service on the web called Pandora. I met Tim in Orlando. There's quite a bit of background about Pandora that Tim describes in this interview. He deferred to his CTO, Tom Conrad when I asked him about technical details. Tom and I did a Swampcast interview shortly after this one.
From Wikipedia:
"Westergren was born in 1965 in Minneapolis. He attended boarding school, Cranbrook Kingswood, during his high school years. He graduated from Stanford University with a B.A. in political science.[2] Following his graduation, Westergren spent twenty years working as a record producer and composer (working as a nanny in between jobs), devoting the majority of his time to emerging artists and independent labels.
In 1999 he started Pandora Media along with two co-founders: Will Glaser and Jon Kraft. The Oakland, Calif., company went public in 2011,[3] reporting $138 million in revenue that fiscal year.
As an early project, Westergren and Glaser created the Music Genome Project, a mathematical algorithm to organize music.[1] As the company's chief strategy officer, Westergren spends the majority of his time traveling the nation and gathering feedback from Pandora Radio users. In 2010 he was listed by Time magazine as one among the 100 most influential people in the world.[4]
In April 2016, Pandora Media announced that Tim Westergren would replace Brian McAndrews as CEO. He had previously served as CEO and president from May 2002 to July 2004.[5]
In June 2017, he announced that he is going to step down as CEO.[6]"

Vanessa Formicola discusses how "invisible" forces shape our code and architecture. She shares patterns like "Cirque du Soleil coding" and "Shared Kitchen Sinks," explaining why technical problems often have social roots. Architects and leaders will learn how to use Social Decision Records (SDRs) and holistic modeling to make the implicit explicit and drive success.
By Vanessa FormicolaIn this podcast, Shane Hastie, Lead Editor for Culture & Methods, spoke to Gonzalo (Glo) Maldonado about the central role of engineering culture, measuring team health through qualitative metrics, and learning from other engineering disciplines.
