Our Story

A pain point is a specific problem that customers of our business are experiencing , and that is “a high intensive labourwork on reinsurance processes and human errors in that era“ and that reminded us the quote “if I had an hour to solve a problem , I would spend 55 minutes thinking about the problem and 5 minutes thinking about solutions“ by Albert Einstein . CoSure Team has spent almost 100 years all together with these problems and now here to bring the utmost effective solutions!
