Prismm Wants to Move Inheritance Inside Online Banking

Prismm is building beneficiary and estate planning into bank accounts from the start to simplify transfers to heirs and keep inherited money at the same bank. The company presented that mission on the Startup Battlefield stage at TechCrunch Disrupt 2026 on Oct. 14, according to TechCrunch.

Prismm was founded in 2020 by sisters Martha Underwood and Shella Sylla, both longtime banking and finance professionals. The idea came from a family emergency. Their father was hospitalized in 2017 after a fall while clearing a tree from a neighbor's roof after Hurricane Irma in Miami, which showed how hard it is to find accounts, documents and permissions when a relative cannot act.

The workflow starts well before death. An account holder can give chosen family members advance access to accounts and documents. After the holder dies, that person can log in once to see assets and documents together and begin eligible beneficiary transfers online. The model favors advance permission over searching for information afterward.

Prismm stores identity checks, consent records and supporting documents ahead of time, so transfers can be completed remotely when relatives live in different states. It connects directly to bank cores, the central systems that record balances and ownership, which keeps beneficiary data and transfer requests inside the bank's official records rather than in paper files, branch visits and back-office queues.

The company has two main products, with a third in development. Prismm Designate lets banks give customers a digital way to update their own beneficiaries. Prismm Anchor gives account holders a secure place to list accounts, documents, property and other assets across different institutions, with limited access for chosen people. Anchor is offered through financial institutions, not as a separate consumer app.

Prismm is based in Tysons, according to the Washington Business Journal. That February report said the company was raising $1 million in a seed round for its wealth transfer platform. In September, it added Prismm Designate to help banks and credit unions connect with beneficiaries before wealth transfers, according to Morningstar. It calls itself an estate orchestration infrastructure platform purpose-built for banks and credit unions.

The broader context here is upkeep and retention. Beneficiary details go out of date. People name a beneficiary once, then marry, divorce, have children and move money without updating it. For banks, old records mean extra work at a hard moment, when heirs arrive with incomplete paperwork and funds are most likely to leave. A self-service update inside online banking lowers that cost and introduces the bank to the heir earlier.

For bank technology teams, the notable choice is to treat estate transfer as core transaction infrastructure rather than as a separate document vault. Document vaults are straightforward to build. Identity proofing, consent capture and eligibility checks for payouts are harder, especially with different state rules for remote completion. Collecting those records while the customer is alive and can respond moves verification earlier.

In my view, that change in timing is worth watching. I have watched my two children adopt financial tools that hide a lot of complexity behind a simple permission screen, and naming a beneficiary has never had that simplicity. If banks can make designation and limited early access as routine as adding a joint owner or setting up alerts, the later transfer becomes execution of an existing instruction. That would leave fewer families rebuilding a financial life from statements and safe deposit boxes, and more balances staying where they started.
