A week on from its IPO registration, it's business as usual for Zynga when it comes to acquiring more studios.

After all, even pre-IPO, it has almost $1 billion in cash and equivalents, and had pointed to expansion of its mobile expertise as a key future strategy.

Northern exposure

In this context, Zynga's 15th acquisition in 13 months is Toronto-based app developer Five Mobile, now known as Zynga Toronto.

Terms of the deal weren't revealed, but as well as the team, including the four co-founders - Ameet Shah, Jeff Zakrzewski, Oliver Tabay, and Troy Hubman - Zynga is acquiring some of the company's assets and IP.

Zynga says it's bought the company because of its work across a multitude of platforms and handsets for 'some of the largest media and technology companies in North America'.

"As a key component of our mobile efforts moving forward, Zynga Toronto will help position us in a hotbed of mobile development talent," it explained.
