Slack buys small, two-man work-collaboration startup Spaces

Slack, one of the many startups making a name for itself in the work-collaboration space, today said it acquired the two-man, bootstrapped startup Spaces for an undisclosed amount. Spaces’ core product is a sharable document in which users can collaborate together with graphics, text, annotations and other work-related items; with Slack providing a chat platform that aims to centralize an enterprise’s work into one locale, the deal makes sense. Slack’s rise to startup stardom highlights the importance major cloud providers are putting on work-collaboration tools, like Amazon’s Zocalo product; Slack is also putting the pressure on Box and Dropbox who have both been boosting their workflow-management features in recent months.

Elastica launches with $6.3M to secure your SaaS footprint

A security startup called Elastica came out of stealth mode on Tuesday, and brought with it $6.3 million in venture capital from the Mayfield Fund. Elastica tries to protect corporate data scattered across the dozens of cloud services companies might be using and, like so many other security startups, is touting its use of data science techniques to accomplish its goal. Elastica does have an impressive pedigree, though, both with the Ph.Ds. on its founding team and with advisers including Rayid Ghani (Obama for America, Edgeflip), Tom Reilly (ArcSight, Cloudera), M.C. Srivas (MapR) and Ion Stoica (UC Berkeley, Conviva, Databricks).
