In a world that makes sense: probably. Keep in mind, Slack is not only raising money because it can but also because the public markets would throttle it like the companies had been in 2015.

That said, Butterfield's move to raise more money simply to be attract more recruits sounds completely crazy. But hey, it's only crazy if it doesn't work.

He seems to understand the awkward position his company is in. As covered in a TC article, Butterfield is prepping his company for the public markets even though there are no real plans to do so. This is evidenced by the near profitability Slack has now.
