OneSignal was born from our experiences running a Y Combinator-backed mobile game studio. From the beginning, we set out to help all marketers and developers from around the world easily send effective messages to their customers.

Prior to starting OneSignal, our personal experience building mobile applications revealed that the status quo of customer engagement was broken. We found ourselves spamming our users with the same, non-personalized push notifications, with no ability to segment, personalize, or understand the efficacy of our campaigns. Before sending an email, we had to upload multiple CSV lists to clunky email platforms. All this effort took precious time away from our ability to improve our games, and it harmed our relationship with our players.

With OneSignal, we’ve led a technology transformation that has helped over a million businesses better engage with their customers. Today, over one in seven mobile applications use OneSignal to effectively engage with their users across channels, including push notifications, email, SMS, and in-app messaging.

We’ve made it incredibly simple to send messages on each channel, and we’ve brought the channels under a single platform so that businesses can easily orchestrate omnichannel experiences that delight their users.

Today, I’m thrilled to share that we’ve secured an additional $50 Million in Series C funding to accelerate our product roadmap and better serve our customers. We’ve partnered with world-class investors from BAM Elevate, who led the round, with additional financial support from existing investors, including SignalFire and Zach Coelius.

The round’s proceeds will be used to enhance our omnichannel messaging and orchestration capabilities. In particular, we’re excited to continue work on our Journeys workflow tool to make it even easier to automate and personalize omnichannel messaging at scale. We’ll also continue to develop our best-in-class email messaging capabilities and expand our analytics tools to provide customers with even more granular insights.

OneSignal is a globally used product. We will continue to expand our geographic footprint to better serve clients in Europe, Asia-Pacific, and Latin America, with global office locations in London and Singapore.
