Enterprise collaboration platform Slack has raised $427 million in new Series H funding at a valuation north of $7.1 billion.

Why it's a big deal: Because while Slack is massive (8 million daily active users and over 70k paid teams) and has subsumed some rivals (RIP Hipchat), this new money reflects how competition is intensifying from deep-pocketed incumbents like Facebook and Microsoft.

Dragoneer Investment Group and General Atlantic co-led the round, and were joined by T. Rowe Price, Wellington Management, Baillie Gifford, Sands Capital and unidentified return backers.

Bottom line: It was just over three years ago that Slack founder and CEO Stewart Butterfield talked about the PR importance of being valued at $1 billion. Now it's actually raised more than that, with $1.27 billion in total funding.

Why it matters: Companies generally issue bonds for one of two reasons — because they're worried about not having enough cash to cover their expenses or because they want to lever up and make risky bets.

Regulators in Europe and Washington are racing to figure out how to govern business' use of artificial intelligence while companies push to deploy the technology.

Driving the news: On Wednesday, the EU revealed a detailed proposal on how AI should be regulated, banning some uses outright and defining which uses of AI are deemed "high-risk."
