US F2P casual publisher Kiwi has closed a $15 million Series B funding round.

Led by Northgate Capital with participation from DFJ and returning investor Sequoia Capital. this brings the total amount raised to $21 million.

Focused on Google Play, Kiwi says it will use the cash to invest further in its mobile titles, while improving its distribution and monetisation practices.

The opportunity remains open

Originally at Tippert Labs, which was bought by Playdom, which was then bought by Disney, Kiwi's core team has worked on titles such as Gardens of Time.

It's currently best known for casual titles such as Shipwrecked, Brighwood Adventure  and the Monsterama series.

"Our early focus in the rapidly growing Android ecosystem has allowed us to build top free-to-play mobile games on Google Play and develop tools that we are making available broadly to benefit all developers," said Kiwi CEO Omar Siddiqui.

"This new funding round will help us to bring these tools to market as we also invest in the next generation of our cross-platform, AAA mobile titles."

"The next generation of gaming megahits is going to be on mobile, and there are few companies with the experience and opportunity to dramatically change the industry – Kiwi is one of them," predicted Northgate's MD Brent Jones.
