Tripinsurance.com is owned and operated by Online Trip Insurance Services, Inc., Monte Sereno, CA
A relatively new online, travel insurance company that markets policies on behalf of BCS Insurance Company, Nationwide Mutual Insurance Company, Old Republic Insurance Company, and United States Fire Insurance Company. They appear to be closely associated with TripMate. The web site name, TripInsurance.com, was formerly used by M.H. Ross which is owned by TripMate and claims are reported to TripMate. Since they appears to be closely aligned you should check out TripMates profile too.
TripInsurance.com compares their products to those offered by other companies however, many of the comparisons are more apples to oranges. In addition their claim to "cut out the middlemen" is questionable since they are in the middle between the traveler and the insurance company. Any savings that might be implied may be a result in product differences.
