Facebook had a rough day yesterday when its stock plunged after a poor earnings report. What better way to pick yourself up and dust yourself off than to buy a little something for yourself. Today the company announced it has acquired Redkix, a startup that provides tools to communicate more effectively by combining email with a more formal collaboration tool. The companies did not reveal the acquisition price.

Redkix burst out of the gate two years ago with a $17 million seed round, a hefty seed amount by any measure. What prompted this kind of investment was a tool that combined a collaboration tool like Slack or Workplace by Facebook with email. People could collaborate in Redkix itself, or if you weren’t a registered user, you could still participate by email, providing a more seamless way to work together.
