Job Details

Hi, we are Appjobs 👋

Founded in 2017, we have helped millions of people find an app or a digital platform to make money. We have become the world's largest community of gig workers along the way.

During our quest to help gig workers, we discovered that these people are tremendously underserved. Applying for insurance or a loan is more often than not a mission impossible scenario. One-size fits all approach is not working for people who are ridesharing, delivering food or groceries, walking dogs, charging scooters, or providing services through freelancing platforms. On the other hand, lenders and insurers lack relevant data about these new job types. Solution? Unveel!
