Notifications Startups funded by Y Combinator (YC) 2026

Pushbullet connects your devices, making it easy and automatic to share almost anything between them. Our mission is to bridge the gap between your phone, tablet, and computer, enabling them to work better together. Why is this important? Simple: in the past few years, smartphones and tablets have taken over people's digital lives. Sharing data between them and with computers, however, can be a real pain. We make it easy and automatic.

Outbound organizes the messages you send around the actions your customers take. We allow non-technical marketers and product people to set up automated email, push notification, SMS or voice messages when you need your users to take an action, then test how well each message works.
