I'm founding a startup in Switzerland and we need insurance in case we break things. I asked for various quotations from various insurance companies in order to buy the best suited for me. I talked for ~ 5 minutes with each representative (what type of work do we do, what will our estimated income be, etc.).
In the end, I received various quotations and the most expensive one was 70% more expensive than our cheapest one for the same services.
The expensive company sent me an email and I replied saying that they were the most expensive. The representative replied wanting to know the cheapest company's quotation.
Is it ethical to share it? To me, there nothing secret by the fact that everyone could've asked the same quotation. Furthermore I suppose it can only make the market more "fluid".
