1+ million mobile app developers and marketing teams use OneSignal to send push notifications, in-app messages, emails, and SMS messages. We started as a YCombinator-backed company. Our founders were frustrated with existing push notification tools, so we built our own system. Our customers can design banners, pop-ups, and interstitials without a single line of code.

When you pick up your smartphone, the first thing you will see are push notifications - maybe there’s a breaking news alert, a football game reminder, a promo from your favorite retailer. Whatever it is, chances are the message you are reading was sent using OneSignal. Now we help businesses send over 10 billion push notifications a day. 

We have raised a total of $35M from investors including SignalFire, Y Combinator, Rakuten Ventures, and Hubspot. OneSignal customers include Volkswagen, Verizon, Burger King, 7 Eleven, Zynga, Virgin Mobile, KFC, and many more. Join us in scaling the business!

OneSignal has a lot of the great tech startup qualities you'd expect, but we don't stop there. Our massive scale and small team, emphasis on healthy life balance and kindness in all our interactions, and focus on ownership and personal growth make OneSignal a uniquely great place to work.

In keeping with our beliefs and goals, no employee or applicant will face discrimination/harassment based on: race, color, ancestry, national origin, religion, age, gender, marital domestic partner status, sexual orientation, gender identity, disability status, or veteran status. Above and beyond discrimination/harassment based on 'protected categories,' we also strive to prevent other, subtler forms of inappropriate behavior (e.g., stereotyping) from ever gaining a foothold in our office. Whether blatant or hidden, barriers to success have no place in our workplace.
