Chris (CEO) here. I’m not aware of anyone that has created a model to fractionally insure a single person as you have described.
There are models and mechanisms for multiple smaller employer groups to band together. For example, association health plans are common with professional trade groups.
While an interesting thought experiment, no, we have never thought about multiple employers combining and contributing to insure a single individual.
Would it be difficult? If you market to consumers, you could give businesses a cost over the phone just like any other business, just on a per person level.
A pooling mechanism is needed. Additionally, the pooling entity would want to meet (or make sure the various fractional employers trying to insure "Hank" meet) federal ERISA requirements for the favorable tax treatment of paying a fractional employee's fractional health insurance premiums.
The next challenge is non-payment of premium. Lets assume Companies A, B, and C each respectively insure "Hank" respectively for 50%, 25%, 25%. They respectively pay $50, $25 and $25 per month in premiums to PoolingEntity. What happens when any of A/B/C fail to pay a premium? The insurance contract would eventually be terminated for non-payment (after a statutory notice period), and poor Hank would be back to being uninsured.
Technologically, I think it could be done. But the legal, regulatory, and administrative complexity would need to be addressed.
Separately, a great resource for reading up on where/how Americans get their healthcare coverage is the Kaufman Family Foundation. Many Americans have more than one source for their coverage. https://bit.ly/3KazKNN
