Google says it’s not making any more tablets

The writing has been on the slate for some time now. Roughly this time last year, we reported that Google had wiped all tablet sales off its site. Turns out that was just a bug, but it seemed like an ominous portent of things to come.

Google still went ahead and launched the Pixel Slate late last year, hoping the device would give users a much-welcome form factor alternative to its high-end Pixel Book. Ultimately, however, the device felt redundant, and now it seems it will be the last of its kind. The company this week admitted that its hardware team is giving up the tablet ghost.

“For Google’s first-party hardware efforts, we’ll be focusing on Chrome OS laptops and will continue to support Pixel Slate,â€� the company said in statement sent to the press today, in response to earlier reports.

Google SVP Rick Osterloh took to Twitter to further clarify “unclear� articles:

Hey, it’s true…Google’s HARDWARE team will be solely focused on building laptops moving forward,â€� he wrote, “but make no mistake, Android & Chrome OS teams are 100% committed for the long-run on working with our partners on tablets for all segments of the market (consumer, enterprise, edu)

Tablets have, of course, proven a tough nut to crack for practically every company that isn’t Apple. Google has taken numerous swings at the space, but never quite found its place in amongst the premium iPad or far cheaper Android/Chromebook alternatives. And while the company once seemed content to treat Nexus/Pixel devices as much as references for its software, it has clearly taken a much more serious approach to its own devices in recent years.

So, goodbye to the Google tablet. For now, at least.

One of NASA’s robotic astronaut helpers just flew on its own in space for the first time

NASA’s very own free-floating Companion Cube equivalent took its own first tentative “steps” in space today, demonstrating its ability to rotate on its own in zero gravity inside the International Space Station. The robot, called “Bumble” and one of a series of Astrobee robots that NASA developed to work along with astronauts on the ISS, is the first ever to fly on its own in space.

Bumble’s first flight wouldn’t necessarily wow at an airshow — the robot essentially flew a foot forward and rotated a bit. But they’re important basic maneuvers in terms of making sure the robot’s propulsion system is working and tuned correctly. Eventually, the plan is for these to operate autonomously and do some basic maintenance work, as well as support experiments, so it needs to be operating exactly as intended before it starts freely sharing space with tender human astronauts.

The Astrobee line currently counts three individual robots among its members, including Bumble, Honey (also already on the ISS) and Queen, which is coming up in July on the next resupply mission, if all goes to plan. Each is equipped with cameras to document experiments performed by humans, and they can network to actually move equipment around. The robots can also dock at a companion station to charge, and each has a little perching arm that lets it grab on to stuff to anchor itself or hold things.

Bumble blinks!

The 1-foot cubed bots were developed at NASA’s Ames research facility, and once fully operational, should free up astronauts to focus on things that only humans can handle — and there’s plenty of that work to go around on the ISS in terms of experimentation and research.

Slack’s value rockets as stock closes up 48.5% in public debut

It was a historic day for Slack (NYSE: WORK). The workplace communication software juggernaut debuted on the New York Stock Exchange up 48% at $38.50 per share after reports emerged Wednesday night that the business had agreed to a reference price of $26 per share.

Slack, founded in 2009 as Tiny Speck, closed up 48.5% Thursday at $38.62 per share. The stock had climbed as high as $42 in intraday trading. Slack’s market cap now sits well above $20 billion, or nearly 3 times its most recent private valuation of $7 billion.

Slack on Thursday became the second large venture capital-backed business to complete a direct listing, an alternative path to the public markets that allows businesses to go public without selling new shares of its stock. Instead, companies are able to bypass the exorbitant fees associated with initial public offerings, like completing a roadshow and hiring investment bankers, and begin trading by selling existing shares held by investors, insiders and employees.

Slack co-founder and chief executive officer Stewart Butterfield is now a billionaire, having held on to an 8.6% stake worth $1.6 billion at the opening price. Accel, its largest shareholder, boast a stake worth a whopping $4.6 billion. Other key shareholders include Social Capital, which owns a stake worth $2 billion, Andreessen Horowitz ($2.6 billion), SoftBank ($1.4 billion) and Slack co-founder Cal Henderson ($646 million).

Slack’s successful opening isn’t surprising. Of the tech businesses to go public in 2019, the enterprise SaaS IPOs (Zoom, PagerDuty, etc.) have performed best. According to SharesPost, enterprise SaaS IPOs are trading, on average, at more than 100% above their IPO price.

Direct listings are a rather risky path to the public markets because of its unproven nature. In Slack’s case, it’s benefited from both its globally renowned brand and Wall Street’s insatiable desire to invest in SaaS.

Spotify, another notable business that opted for a direct listing, has performed relatively well since exiting in 2018. Initially, the music streaming business opened trading up 25% from its reference price of $132 before closing down 10% after its first day of trading.

Slack has previously raised a total of $1.2 billion in funding from investors, including Accel, Andreessen Horowitz, Social Capital, SoftBank, Google Ventures and Kleiner Perkins. In late 2018, the company closed on more than $400 million in new funding at a valuation of $7.1 billion.

Now that it’s public, all eyes will be on its financials. Weeks ahead of its direct listing, Slack posted an amended S-1 with an updated look at its path to profitability.

Slack posted revenues for the fiscal first quarter ending April 30 of $134.8 million on losses of $31.8 million. Slack’s most recent revenues represent a 67% increase from the same period last year when the company lost $24.8 million on $80.9 million in revenue.

For the fiscal year ending January 31, 2019, the company reported losses of $138.9 million on revenue of $400.6 million. That’s compared to a loss of $140.1 million on revenue of $220.5 million the year prior.
