Slack’s IPO is first time on here that I’m seeing more than 1 or 2 black folks secure the bag because their employer is going public.

Wow, pretty cool Easter Egg for Slack's IPO

If you type the age you lost your virginity into your team slack channel today with /IPO you get a free share of Slack stock

I tried it and it worked!!!

RT for free stock

Slack is planning to go public on Thursday and largely steering clear of Wall Street and its high fees. The IPO reference price is set at $26 a share https://t.co/bxqyPakiWz

It’s a milestone day for us, but also a day of thinking about work. About ours, and yours, how grateful we are that you let us be part of your working day, and how we can continue to try and make it better. Soppy? Perhaps! But still true. https://t.co/u7g23ouufL

Slack will go public at a valuation of $15.7 billion, report @cdriebusch @maureenmfarrell

They add: "Slack’s stock is expected to open significantly higher"

It was valued at $7.1 billion last August.https://t.co/H7QyfnonQw

There it is - Slack opens at $38.50 per share - giving it a market cap of more than triple its last private valuation

As Slack prepares to go public, some of us are still figuring out how available we want to be for bosses and coworkers https://t.co/QHjqCA1t94

3 Slack un-IPO thoughts before heading to 6 Flags to ride coasters w/ E:

1/ As with Spotify, the success/failure here is all about volatility (or lack thereof).

2/ They got a great day to list, like the bizarro Uber.

3/ Airbnb is watching VERY closely.

I remember thinking this chat thing would be huuuuge when I first signed up. Happy IPO day, Slack friends! https://t.co/nHIgfuUtro

what's cool about slack is you still need email—for things from outside the company at the very least, and also longer messages—so now you just have twice as many things to worry about https://t.co/HgYSUttmy5

Slack set the trend of blending consumer software feel with an enterprise focus. This is the right approach since all workers are also consumers and quality UX will increase usage and engagement.

Congrats @stewart! https://t.co/haigo8RoIg

A true SV "woah" moment for me. We once shared a warehouse wall with Slack folks, when they were still doing the Glitch thing. Vaguely remember them (Stewart?) showing us their IRC-like chat app they were building on the side https://t.co/dByviOAzdI

It feels like all of Silicon Valley is here for the Slack IPO.

HI FRIENDS WELCOME!!

I don't know if it's just BuzzFeed but ever since we really internalized that even private Slacks are discoverable, all the real talk happens off-Slack: https://t.co/CI1J0tkJwc
