Seth Fiegerman says, “Twitter has agreed to buy TapCommerce, an ad tech firm, the two companies announced late Monday. Terms of the deal were not immediately disclosed, but Re/code reports it may have been around $100 million.

TapCommerce describes itself as a mobile ad retargeting and app reengagement service. To put that more simply, TapCommerce sells ads designed to prompt users to open up apps they’ve already downloaded. The company was founded in 2012 and raised more than $10 million in funding”.
