Twitter has bought Irish mobile software platform, OpenBack, for an undisclosed fee.
The Dublin based start-up is to be integrated into Twitter and will wind down its own operation.
OpenBack was set up six years ago by chief executive David Shackleton, Christian Ryder and Nicolas Pabion.
The company helps mobile apps process data on the device itself, without needing to go through a third-party server.
This device-side control of push notifications makes apps more engaging and improves privacy, Twitter claims.
The social network said it acquired the company as it wants to ensure that what people are notified about on Twitter is relevant, timely and engaging.
"We're so excited about this; @christian_ryder, @theapprocks and I set out 6 years ago to try and make push notifications truly user first for billions of people in a new way, and this opportunity to work with @Twitter fulfils that in so many ways more than we ever imagined," said David Shackleton in a tweet.
OpenBack will now join the product team in Twitter and focus on notificiations.
"OpenBack and their talented team joining Twitter will help us improve our ability to deliver the right notifications at the right time, in a way that puts people’s privacy first," said Jay Sullivan, Head of Consumer Product at Twitter.
"We’re thrilled to have them join the flock and look forward to seeing their impact. Welcome!"
David Shackleton is a co-founder of mobile top-up technology provider Ding, where he worked for 13 years until 2018.
