Knock Knock raises $4m for messenger-based mobile games

Start-up has raised $6 million since June 2018

San Francisco based mobile firm Knock Knock has successfully closed a Series A financing round to the tune of $4 million.

The round was led by March Capital Partners, whose managing director Gregory Milken will join the Knock Knock board. There were also contributions from previous investors London Venture Partners, Raine Ventures and Ludlow Ventures.

The company has raised $6 million since June 2018.

Knock Knock was founded by former executives from leading mobile companies including Zynga, Jam City, Glu Mobile and Gameloft. It specialises in instant games for messenger platforms such as Facebook Messenger.

The $4 million will be used to grow its games portfolio, launch titles on new platforms such as the hugely popular Chinese app WeChat, and hire more development and user acquisition staff -- both in its San Francisco HQ and Toronto studio.

Its games include Golf Buddies, Car Match Hollywood, Sticker Pets and Sticker Pets: Diner Match. Two are already available on Facebook Instant Games and have achieved over five million installs. A third will be released on multiple platforms later this year, including WeChat and Facebook Instant Games.

"We founded Knock Knock around the core belief there was an underserved market for truly accessible games that allow people to connect instantly," said co-founder Andrew Friday. "As players continue to spend more and more time on chat platforms and social networks, we want to bring them new and exciting social gaming experiences.

"With the introduction of 5G and continued improvement of frictionless technologies, App Stores will be an inferior customer and business experience. I believe the future of gaming will feel more like a social network where you can easily engage with friends to play, chat, and share with the lowest barrier to entry."
