It's mind-boggling how these 23 Silicon Valley power players all used to work at Yahoo

Rosensweig spent over 5 years as Yahoo's COO. He was a popular executive and active operator at Yahoo during the Terry Semel era.

Rosensweig cut his teeth at Ziff Davis, the publisher behind companies like PC Magazine and ZDNet.

One of his biggest legacies at Yahoo could have been the acquisition of Facebook, which fell apart at the last minute.

Goldberg joined Yahoo when his online music company Launch Media was acquired in 2001. He was in charge of Yahoo's music business, and spent nearly 6 years there, before moving on to run his own company called SurveyMonkey, an online survey platform last valued at $2 billion.

Unfortunately, Goldberg died during his vacation last year. He's still remembered as one of the most beloved tech executives in Silicon Valley.

Garlinghouse joined Yahoo in 2003 and spent over 5 years as SVP running its communications business. He's best known for the "Peanut Butter Manifesto," a company-wide email he sent to urge the company to focus on its core business.

After leaving Yahoo, Garlinghouse spent time at AOL and as CEO of online storage company HighTail. Now he's the COO and president of payments software company Ripple Labs.

Butterfield joined Yahoo when it bought his photo-sharing app Flickr.

But he never really enjoyed his time there. After just 3 years, Butterfield left the company by writing a metaphor-filled resignation letter that ended up going viral.

He now leads Slack, a $2.8 billion business communication app maker that's considered one of the fastest-growing startups ever.

Lu spent 10 years at Yahoo, leading the company's search and advertising technology. He was a key part of Yahoo's growth, and was later personally recruited by ex-Microsoft CEO Steve Ballmer.

Lu eventually joined Microsoft in 2008. He's now responsible for all the R&D across Microsoft Office, Office 365, SharePoint, and Bing, among many other things.

Acton joined Yahoo as employee #44 in 1996, while Koum came in six months later. They both worked as infrastructure engineers, and spent nearly 9 years at Yahoo.

In 2007, both Acton and Koum left Yahoo and traveled around the world for a bit. They applied to work at Facebook later, but never made it. Instead, they became part of Facebook in 2014, when their messaging app WhatsApp was acquired for $19 billion.

Most people remember Yang as the cofounder of Yahoo. Some people remember him for his role in Yahoo's failed acquisition talks with Microsoft in 2008.

In any case, there would be no Yahoo without Yang and his legacy will always be tied to the company he cofounded in 1994.

In 2012, Yang left Yahoo for good, stepping down from the board and all related positions at the company.

But he's been able to make a quiet comeback, recasting himself as one of the most prolific enterprise VC investors in Silicon Valley over the past few years.

Anne Toth was in charge of Yahoo's privacy and user policy, spending over 13 years there. In 2009, she testified at a US House subcommittee hearing about internet privacy policies.

But about a year after being named Yahoo's Chief Trust Officer, Toth abruptly left the company for Google to oversee user privacy for Google+. In 2014, she was hired by Slack to lead its privacy policies.

Irving joined Yahoo in 2010, after spending 15 years at Microsoft. He served as Yahoo’s Chief Product Officer for about 2 years, making real progress on projects that connected Yahoo's disparate backend technologies.

Although Irving was one of ex-Yahoo CFO Tim Morse’s most trusted officers, he resigned in 2012 after clashing with ex-Yahoo CEO Scott Thompson amid big restructuring plans.

Irving has been GoDaddy's CEO for more than 3 years now.

Dickerson came to Yahoo in 2005 after spending over 5 years as InforWorld’s CTO. He was in charge of Yahoo’s developer network and live video platform, and later created the Yahoo Hack Day, its first internal hacking program.

In 2008, Dickerson left Yahoo to join Etsy as CTO, running its engineering team. Three years later, he was promoted to CEO, and took the company public last year.

Awadallah was Yahoo’s VP of engineering for over 8 years, running the product intelligence team that was one of the first to use Hadoop, a popular data analytics framework.

In 2008, he cofounded a company called Cloudera, a data analytics company that provides Hadoop-based software. Cloudera was last valued at roughly $5 billion.

Riley was a star executive at Yahoo, serving most recently as its top sales guy in the Americas region. He spent nearly 13 years at Yahoo.

Riley was once considered for the COO job under Yahoo CEO Marissa Mayer, the position that eventually went to Henrique de Castro. In 2013, he joined music discovery app Shazam as its CEO.

Decker was a star internet analyst in the 90s, and was recruited by Yahoo cofounder Jerry Yang to be its CFO in 2000. She played a big role in turning Yahoo into a more mature company, orchestrating cost cutting moves that impressed Wall Street early on.

Decker was once considered a CEO candidate for Yahoo before Carol Bartz won the position. Some people blame her for mishandling the Microsoft deal, but there’s no question she played a big role in Yahoo’s history.

Savitt was one of the first executives hires by Yahoo CEO Marissa Mayer, when she was brought in as chief marketing officer in 2012.

She was in charge of Yahoo’s media and marketing sides, but failed to turnaround the company’s advertising business which continue to fall behind Google and Facebook. She left Yahoo in September 2015 to become CEO of Hollywood studio STX Entertainment.

In her role as Yahoo’s Chief Development Officer, Reses oversaw everything from corporate development and partnerships to human resources and organizational restructuring. She was one of Mayer’s favorite and loyal lieutenants.

But only three and half years after joining Yahoo, Reses abruptly left to join payments upstart Square as to head up its capital lending business. Our sources told us Mayer and Reses increasingly disagreed over HR issues recently, but there wasn’t a single dramatic moment that caused Reses to leave Yahoo.

Coleman helped build up Yahoo's global sales team early on when he was hired as EVP of global sales in 2001. He came from Reader's Digest, and is largely credited with teaching Yahoo how to sell ads.

But he had a fall out with long-time Yahoo executive Sue Decker, and eventually left the company in 2008, according to the book "Marissa Mayer and the Fight to Save Yahoo."

Coleman was also president of Huffington Post and ad tech company Criteo, before joining Buzzfeed in 2014 to replace ex-Buzzfeed president Joe Steinberg.

Stamos' time at Yahoo was brief, but it was a big deal when he was first hired as its chief information security officer.

Stamos is a respected leader in the cyber security space, and vocal opponent of the government's secret surveillance programs. At Yahoo, he clashed with the director of the NSA over the government's data collection policy.

He was expected to beef up Yahoo's privacy and security measures, but ended up leaving Yahoo after just 16 months to become Facebook's CSO last year.

Heckman was Yahoo's top dealmaker under interim CEO Ross Levinsohn, right before Marissa Mayer was hired as Yahoo's boss.

But he clashed with Mayer's personality and long-term vision for the company, and was let go soon after Mayer settled into her job at Yahoo.

Then he returned to the sports website Scout.com, a company he founded and sold to Fox for $60 million in 2005, as CEO.

During his four years at Yahoo, Horowitz was in charge of the main product decision team called Advanced Development Group, often serving as the company's public face for product announcements.

But in 2008, during the week of a massive layoff, Horowitz announced his resignation from Yahoo, saying it was voluntary. He's now leading a team comprised of Google Photos, Google News, Google+, and related infrastructure services.

Airey headed up Yahoo's Europe, Middle East, and Africa business for two years from 2013 to 2015. She became Getty Images CEO in October 2015.

Prior to that, Airey was the chairman and CEO of UK's Channel Five, which is now owned by Viacom.

Dulski joined Yahoo in 1999 when it had less than 500 employees. She worked in various divisions, including Yahoo Shopping and Commerce, as well as marketing and Auto.

After nearly 9 years at Yahoo, Dulski left to found her own startup called The Dealmap, which was acquired by Google. Two years later, she joined social petition platform Change.org as its president and COO.

Barrett joined Yahoo in 2012 as its chief revenue officer. But his time at Yahoo was short-lived, as he left just 6 months later. It was a period of turmoil for Yahoo at the time, with the board debating between Ross Levinsohn and Marissa Mayer for the next CEO.

Before Yahoo, Barrett was at Google, but his time there was brief too. He joined Google in 2011 when it bought his ad tech company Admeld for $400 million.

Barrett was hired as Millennial Media's CEO in January 2014. It's one of the larger ad tech companies, and it was acquired by AOL last year for roughly $238 million.
