A Mark Cuban-backed AI startup is helping families turn conversations with their elderly relatives into lasting memories

AI record elderly conversations: Mark Cuban-backed startup turns family talks into searchable digital archive

A Texas startup backed by billionaire Mark Cuban launched an app that records, transcribes and permanentlyarchives conversations between families and their aging relatives using artificial intelligence.

Remento generated $3.7 million in seed funding last year and already stores more than 15,000 hours of spoken family history for paying users across the United States.

The company’s timing coincides with the largest elder population boom in U.S. history as 73 million baby boomers move into their 70s and 80s. Adult children increasingly seek ways to preserve voices and stories before they disappear, Remento co-founder Charlie Greene told reporters on Tuesday.

Families pay $99 annually for the service. The app prompts users with weekly questions like “What was your first job?” or “How did you meet Mom?” Voice memo replies upload to Remento’s servers where natural language processing converts speech to text, identifies proper names, and creates searchable chapters.

Greene said the difference between Remento and basic smartphone recordings lies in the automatic organization. “No one goes back to listen to 400 hours of raw audio,” he said. “Our AI breaks it into 3-minute stories, tags each by topic, and builds a personal timeline.”

The technology works by isolating individual speakers, removing background noise, and detecting emotional peaks in conversation, according to the company’s technical documentation reviewed by GlobalBeat. The system then recommends chapter titles such as “Childhood in Detroit” or “Vietnam deployment.”

Privacy advocates question whether elderly users understand what happens to their data. Caitriona Fitzgerald of the Electronic Privacy Information Center said companies must obtain clear consent from seniors who may not grasp cloud storage terms. “These recordings contain biometric voiceprints and intimate family details,” Fitzgerald wrote in an email. “Once uploaded, users lose physical control.”

Remento’s privacy policy states the company owns “anonymized and aggregated” versions of all recordings and can share them with third parties for research. Families can request deletion but the process takes up to 30 days according to the policy.

Cuban’s investment came through his Radical Investments fund after Greene cold-emailed the Shark Tank star in 2022. “I immediately saw the market,” Cuban told Fortune magazine in an interview published this week. “Every family has someone they wish they’d recorded more.”

The app competes with StoryCorps, a nonprofit that has collected 650,000 interviews since 2003, and StoryWorth, a subscription service that emails relatives weekly questions then mails compiled books. Remento differentiates itself by focusing on audio preservation rather than printed products.

Early adopters include Susan McGill of Pittsburgh who began recording her 87-year-old mother last September. McGill provided screenshots showing 42 recorded stories totaling 3.4 hours of audio. “She has dementia now but still recognizes her own voice when we play them back,” McGill said via phone.

Another user, James Wu of Seattle, uploaded conversations with his grandmother before she died in February. “The AI caught her Chinese accent perfectly,” Wu wrote in a Facebook review. “My kids can hear their great-grandmother say their names decades from now.”

The company employs 14 engineers in Austin and plans Spanish and Mandarin versions by 2025 according to hiring posts on LinkedIn. Greene said international expansion requires new language models but the underlying architecture scales easily.

Medical researchers express interest in the dataset for dementia studies. Dr. Maria Santos at Stanford Medicine said longitudinal voice recordings could reveal early cognitive decline patterns. “Speech cadence, word-finding pauses, and vocabulary richness change years before diagnosis,” Santos wrote. “Millions of hours would revolutionize our understanding.”

Remento states in its research partnership terms that any academic use requires “explicit opt-in” from users who can revoke permission instantly.

Background

The market for memory preservation technology expanded rapidly after 2015 when smartphone ownership among seniors passed 50 percent for the first time according to Pew Research Center surveys. Companies began offering simplified recording apps targeting the 41 percent of U.S. adults who provide unpaid care to aging relatives reported by AARP in 2023.

Investment in digital legacy tools surged during the pandemic as families separated by lockdowns sought connection through technology. StoryWorth sold to Ancestry.com for an undisclosed nine-figure sum in 2021 while Saga reached $15 million in annual revenue selling lifetime storage plans.

Current federal law offers no specific protection for posthumous digital assets, leaving companies to set their own policies about data retention after death. Only eight states have passed statutes granting executors authority to access deceased users’ digital accounts according to the Uniform Law Commission.

What’s Next

Remento plans beta testing of video recording capabilities this summer and will introduce AI-generated memory books combining audio clips and still photos by year-end according to product roadmap documents viewed by GlobalBeat. The company aims to break even with 60,000 subscribers before seeking Series A funding in early 2025.

Whether families ultimately value audio permanence remains uncertain. Greene admitted that users rarely revisit recordings once initial novelty fades. “The real metric is whether children of our customers subscribe when it’s their turn,” he said. “That will tell us if we built something lasting or just another tech toy.”
