Whyd

We make a beautiful, great sounding, voice-controlled speaker.

Whyd is a free social music platform designed for music lovers to keep, play, and share all of the internet's music. It is the missing link between places where people post music to stream, like YouTube and Soundcloud, and the places where people share music, like Facebook, and Twitter. The internet is the biggest source of music ever. There are billions of songs available to stream for free. But the music landscape is fragmented, between the multitude of different platforms where people post music, and the places where people share and talk about music. They believe that music lovers need their own platform, that serves as a tool to organize and listen to the web, and a social network that is seamlessly integrated into the listening and curation experience.

At Wifi Dabba (YC W17), we are building a low cost, scalable & distributed Wi-Fi infrastructure to connect next billion users online. We do this by deploying a grid of lasers (Free Space Optics) over the cities & town and bring cheap and fast internet for everyone. We enable anyone to buy 1 gig of data access at a time at a price they can afford. Sachetization of internet access is the foundation to rebuilding internet for all. We do this by leveraging crypto and blockchain to truly make internet infrastructure ownership distributed — our vision is to be connectivity layer for the Web3 world.
