When Twitch Prime was originally released one of the major issues was reminding people that their token was available. I built primeminder as a tool to remind people to renew their Twitch Prime subscription via email notifications: https://github.com/gravyboat/primeminder, the plan was to eventually advertise in the body of the emails once the user base was large enough.

The second was a remote job board like weworkremotely called remote-first (https://github.com/gravyboat/remote-first). This was when weworkremotely was younger and I was pretty dissatisfied with the fact they didn't even support searching for jobs, it was just a messy list that was a pain to search so I thought I could do better to solve this.

Both projects failed.
