Meet the Founder
Jeff Yang, FSA
Founder, IBNR.net
Hi, I'm Jeff Yang, FSA, founder of IBNR.net.
Over my decade-long career as a healthcare actuary, I have certified numerous Statements of Actuarial Opinion, several specializing in IBNR estimation. In 2022, I shifted my focus to building consumer products, and created The Actuarial Nexus and Actuarial Exam Pass Rates - platforms now utilized daily by the actuarial community.
Having worked with different IBNR models at four different organizations, I found that many of the methods and procedures to develop reserves could benefit from more automation and standardization. While each organization faces unique challenges, the underlying calculations for setting reserves remain consistent. I'd love to demonstrate how IBNR.net can expedite the loss reserving process for you and your organization, so that you can focus on business decisions and high-level analysis, not data preparation and project management.
For enterprise customers, we are here to help integrate custom solutions. IBNR.net is not here to reinvent your reserving methodology (quite the opposite - we want the platform to fit your needs). If there are specific workflows or methodologies you'd like to see on the platform, let us know so we can add it.
