Slack announced that it has confidentially submitted a draft registration statement with the Securities and Exchange Commission (SEC) relating to the proposed public listing of its Class A common stock. It is expected that the public listing will take place after the SEC completes its review process.

Reuters reported in December of 2018 that Slack hired investment bank Goldman Sachs to lead its initial public offering (IPO) in 2019. According to Reuters, Slack is hoping to fetch a valuation of well over $10 billion in its IPO.

Crunchbase recently reported that Slack disclosed that it had 10 million daily active users. Slack also noted it has 1,500 apps in its directory and penetration into 65% of the Fortune 500.

What does this mean for Slack users? So far, the most notable change is Slack’s new logo. It is understandable for users to become a bit nervous after hearing that Slack, something many people use for work-related projects and communication, may go public. We are just going to have to wait and see what happens next.

Slack posted an apology and an update after its controversial decision to block accounts of users who had visited and logged on from Iran. Slack acknowledges that it did not handle communication well in regards to their decision to block some users.

The problem appears to have happened when Slack updated its system for applying location information to comply with U.S. trade embargoes and economic sanctions regulations.

Soon after updating, we discovered that we made a series of mistakes and inadvertently deactivated a number of accounts that we shouldn’t have. We recognize the disruption and inconvenience this caused and we sincerely apologize to the people affected by our actions. In fact, we also apologize to the people whose accounts we intended to disable in order to comply with these regulations. We did not handle the communication well and in both cases we failed to live up to our own standards for courtesy and customer-centricity.

Slack says it did not block any user based on their nationality or ethnicity. What happened was, at least in part, because Slack uses location information principally derived from IP addresses to implement required blocks.

In my opinion, Slack did the right thing by publicly apologizing for its mistake and also for providing an explanation of what happened. They are being transparent about what led to their mistake. In addition, Slack says it is working hard to restore access to users who access was blocked in error. Slack also provided an email address where users can let Slack know if they made a mistake in blocking a specific user’s access.

It is worth noting, however, that Slack will continue to update their systems over the next few weeks and will be blocking service to IP addresses associated with an embargoed country.

If you travel to an embargoed country, you will temporarily lose Slack access while you are there. I suppose this could potentially affect people who travel to certain countries to visit family over the holidays.
