Facebook’s appetite for acquisitions has not been sated by the 1 billion dollar purchase earlier this week of photo-sharing app Instagram.

On Friday it snapped up the mobile customer loyalty firm TagTile for an undisclosed sum, in advance of its imminent IPO.

“Today we are happy to announce that we are joining Facebook and that they area acquiring substantially all of our assets,” TagTile wrote in a statement on its website.

The company said it would cease taking on new customers and that “Tagtile as it exists today won’t be a part of what we do at Facebook.”
