Tanwi Hangekar
Founder & Consulting Actuary
Tanwi Hangekar is the founder of Arbor Actuarial LLC and brings over a decade of specialized actuarial modeling experience in the North American Life & Annuities space. She is a Chartered Actuary and Fellow of the Institute and Faculty of Actuaries (FIA, C.Act, UK) as well as a Fellow of the Society of Actuaries (FSA). She holds a BSc (Hons) in Actuarial Science from Bayes Business School (formerly Cass), City, University of London.
Tanwi is a recognized specialist in Moody's AXIS software and has held pivotal roles in high-visibility, cross-functional model transformation initiatives driven by US GAAP LDTI and IFRS 17 regulatory changes. Her experience spans the full lifecycle of actuarial model development — from building and validating regulatory-compliant functionalities to enterprise model stewardship across complex annuity portfolios. Her IFRS 17 engagements further expanded her expertise to encompass traditional Canadian life insurance products.
As lead modeler on multiple model conversion projects, Tanwi has been responsible for establishing in-house AXIS modeling capabilities, developing training programs, and laying the technical foundation for enterprise modeling teams.
Tanwi's international background — having lived across Japan, the Seychelles, the United Kingdom, and India — informs her distinctly global perspective. She founded Arbor Actuarial with the vision of making exceptional project management expertise, meticulous attention to detail, and the ability to deliver immediate impact accessible to insurers worldwide.
