AmpMe

The company launched its app in September 2015 and quickly gained traction, achieving one million downloads within four months. A significant milestone was securing $8 million in a Series A funding round in May 2016, led by Relay Ventures, which brought the company's total funding to $10 million USD. This capital was aimed at expanding the team, product development, and forging strategic partnerships. The app's user base continued to grow, hitting 4 million downloads by May 2017.

AmpMe's core product is a free mobile application for both iOS and Android that allows a "host" to stream music, which is then played in perfect sync on the devices of friends who join the "party". Initially supporting SoundCloud, the service expanded to include sources like YouTube, Spotify, and users' personal music libraries. The application's proprietary audio fingerprinting technology is a key feature, using server-centric matching to ensure precise synchronization without relying on Bluetooth or Wi-Fi direct connections, although it does require an internet connection via cellular data or Wi-Fi. An offline mode is also available, where the host can create a personal hotspot to stream music from their device's library. The system is designed to be cross-platform and can also sync with Bluetooth speakers connected to individual phones, allowing for a mix-and-match sound system.

The business model primarily targets social music listeners. While the app is free to download and allows users to join parties, hosting more than one party requires a subscription. This freemium approach encourages viral adoption, as the app is inherently social and requires multiple users to function. The platform includes social features such as user profiles, following others, virtual parties, and in-app chat. The technology is robust enough to have set a world record by syncing 22,000 devices simultaneously.
