Stewart Butterfield and Jen Rubio are Silicon Valley’s newest “it” power couple.

Rubio and Butterfield, worth $130 million and $1.3 billion, respectively, are both cofounders of wildly successful companies. Rubio’s Away luggage brand recently earned a $1.4 billion valuation just three years after it was founded, while Butterfield’s Slack went public this week.

On June 2, Butterfield confirmed in an Instagram post that he had officially proposed. Rubio posted similar photos a few days earlier on May 27. The news comes just weeks after Butterfield jokingly proposed to Rubio on Twitter. Aside from this stunt – which sparked confusion from coworkers and the broader Silicon Valley network alike on social media – their relationship has remained largely under the radar.

They're power players in their own right, both running billion-dollar businesses.

Butterfield, who is 16 years Rubio's senior, continues to make headlines after his company, Slack, went public on June 20. Despite running high-profile companies, much of their relationship has been under the radar.

He holds a bachelor's degree from the University of Victoria and master's degree from the University of Cambridge. Both degrees are in philosophy.

Before founding Flickr, Butterfield started an online-gaming company with his Flickr cofounder and then-wife, Caterina Fake; they were married from 2001 to 2008. The pair founded the company, called Ludicorp, along with Butterfield's friend Jason Classon.

After the startup failed to raise the money needed, the couple founded the photo-sharing platform Flickr. The company later sold to Yahoo for $20 million in 2015. Butterfield and Fake joined Yahoo in the acquisition - Butterfield worked there for three years.

The couple separated in 2008 and have a 12-year-old daughter together.


Butterfield serves as Slack's CEO, while his cofounder Cal Henderson is the company's chief technology officer. The company went public this week.

Business Insider's Julie Bort reported that the pair stands to make millions, if not billions, off their stakes in the company. Butterfield's stake is worth more than $1.7 billion, while Henderson's is worth over $672 million.

After working at Johnson & Johnson through Penn State's co-op program, Rubio decided to pursue a full-time job offer before completing her last few credits. The professional experience led to positions at Warby Parker and All Saints in London, where she worked as the head of innovation.

The pair met working at Warby Parker and started Away in 2015 after Rubio was forced to buy a new suitcase in an airport. Today, the brand is worth over $1.4 billion.

Rubio has said she travels more than 200,000 miles a year.

When asked about her morning routine in a March interview with Marie Claire, Rubio said, "Whatever my first thing of the day is, I make sure to wake up three hours before that to workout, read, meditate, catch up on emails, or chat with my boyfriend, since usually we're not in the same place."

She did not, however, specify that the boyfriend was Butterfield.


While Butterfield's and Rubio's respective Instagram feeds feature some photos of them together, not much is publicly known about their relationship.

In January, Rubio shared a photo of the two of them together, captioning the photo, "more keys to lose."

And on March 21, Rubio wished Butterfield a happy birthday by posting a photo of him smiling happily with two ice cream cones in Rome.

On May 14, following news of Away's $1.4 billion valuation, Butterfield proposed to Rubio over Twitter in what later turned out to be high-profile joke.

Rubio retweeted a Wall Street Journal article reporting the news of the valuation, along with the question: "Let's make today a double-whammy - Jennifer, will you marry me? Promise I'm not just a golddigger."

The tweet confused employees of both companies, eventually causing Rubio to clarify that Butterfield was joking.

"It was just a joke," Rubio told Forbes about the proposal the next day. "He's very supportive and has a weird sense of humor."


However, on June 2 — less than three weeks after the joke Twitter proposal — Butterfield announced on Instagram that he had officially asked Rubio to marry him.

The slideshow he posted included 10 photos of the couple and ended "with one taken just a few minutes" after Butterfield proposed.


Rubio, for her part, confirmed the news on her own Instagram account, posting photos of the two newly engaged executives.

The photos, posted three weeks ago, showed Rubio wearing an engagement ring.


According to The New York Times, the proposal took place over Memorial Day while the couple was hiking in Tofino, British Columbia.

"Ms. Rubio said she momentarily wondered if he was only proposing because of Twitter, asking, 'Are you serious?'" The Times reported.

No immediate wedding plans have been announced.
