Salesforce.com has acquired communications start-up Thinkfuse in a move thought to boost its social enterprise solution Chatter.

The Seattle-based enterprise SaaS provider uses email as a tool for publishing employee status reports, which are then searchable across the organisation.

Thinkfuse announced in a blog post that the team will be joining Salesforce.com and will cease its operation and service effective July 25, 2012. Following this, all customer data will be deleted.

No financial details of the deal were given.

“We started Thinkfuse with a simple idea to help teams communicate more effectively. We now have an amazing opportunity to pursue that passion on a much larger scale at salesforce.com – one of the leading companies in the space,” said Thinkfuse founder Aydin Ghajar.

The deal marks the latest in Salesforce.com’s acquisition spree, which include the recent buyout of perks management start-up ChoicePass and social media monitoring firm Buddy Media.

Microsoft today also joined the ‘social arms race’ with the acquisition of social enterprise tool Yammer.
