Prismm Streamlines Inheritance for Banks
14 Oct
Summary
- Prismm integrates beneficiary planning into accounts from day one.
- The startup digitizes the manual process of asset transfer after death.
- Prismm helps banks retain billions lost annually to estate attrition.

Prismm, a startup established in 2020 by banking veterans Martha Underwood and Shella Sylla, is set to present its innovative solution at TechCrunch Disrupt 2026. The company is developing infrastructure to help banks manage the transition of assets after an account holder's death.
This problem stems from personal experience, highlighting the difficulty families face in accessing financial information during emergencies. Prismm addresses this by digitizing the manual process, allowing account holders to pre-designate beneficiaries and grant them digital access to accounts and documents.
Prismm offers two core products: Prismm Designate, for updating beneficiaries, and Prismm Anchor, a secure asset-tracking system integrated with financial institutions. A third product, Prismm Continuity, is forthcoming to guide staff and families through the transfer process, aiming to keep assets within the institution.
