Prismm helps banks keep inherited money in-house

When an account holder dies, families often struggle to locate accounts, understand bills, and manage assets during an emergency. Startup Prismm tackles this challenge by integrating beneficiary and estate planning directly into accounts from day one, simplifying asset transfers to heirs. The company presented its mission on the Startup Battlefield stage at TechCrunch Disrupt 2026 on October 14, 2026.

Prismm was established in 2020 by sisters Martha Underwood and Shella Sylla, both boasting decades of experience in banking and finance. The duo developed the concept from their own encounters managing family affairs during crises, a vision that solidified when Underwood worked at a bank amid the COVID-19 pandemic and witnessed families scrambling to navigate accounts after losing a loved one.

The platform enables account holders to grant designated family members pre-approved access to accounts and documents. Upon the account holder's death, the designated individual can log in, view assets in one place, and initiate digital beneficiary transfers remotely. Because identity verification, consent, and supporting paperwork are already on file, the entire procedure can be completed even if family members reside in different states.
