Help! Looking for embedded insurance provider for a new marketplace

Hi, I am looking for embedded insurance for a new gig-work marketplace similar to taskrabbit. I have been contacting insurance companies and can't seem to get a response so I'm looking to the world wide web of reddit. Please help!

I am looking to have embedded insurance at the point of sale of a gig-work marketplace based in the US. Gig workers do different types of services and I'd like to make the process seamless to purchase insurance at the point of sale or I'd like the marketplace to provide blanket insurance for all gig-workers on the platform similiar to how Airbnb has host liability insurance for all airbnb hosts. If you have any advice how about this works or what I can connect with to get this in place - please comment!
