Comingle is an interesting idea that would act as a pseudo emergency fund to provide a stable week to week income for their users. It could act to stabilize your income if you have an irregular income or as an backup plan for when you lose a job or income source.
Disclaimer: I am not affiliated with them. I just got this in an email newsletter and was intrigued.
Actually that was my bad. They use guaranteed on their website (which is a more accurate descriptor) and I got it mixed up. Either way it is less conditional than most jobs.
