We launched a zero-knowledge Family Vault for digital inheritance
Hey IH! I just shipped something I’ve been quietly building: a zero-knowledge Family Vault to preserve a family’s most important memories, documents, and digital assets so they can be securely passed down across generations. Press release just went live and I’d love your feedback and ideas.
Problem
Families lose access to critical digital assets when someone passes away
Password managers don’t solve documents/memories; cloud drives don’t solve inheritance or privacy
Estate planning is fragmented, not designed for multi-generational handover
What we built
A zero-knowledge Family Vault: all encryption happens client-side; we can’t decrypt your data
Designed for families, not just individuals: stories, recipes, wishes, milestones, heirlooms
Time-delayed access and emergency protocols for the real world (incapacitation/death)
Why it’s different
Zero-knowledge by design (AES‑256 + PBKDF2): we never see your keys
Family-first UX: roles, granular privacy, sharing, “Family Vault” categories
Scheduled delivery: birthday/anniversary messages and future-dated items
Auditability: activity trails; device fingerprinting; MFA
Early traction
Tens of families onboarded in beta; 42% migrated to zero-knowledge mode
Strong interest from estate planners and family offices (early pilot conversations)
Tech/ops notes
Stack: React + Express + MongoDB, Auth0, S3; client-side crypto flows
Hardest part: zero-knowledge UX trade-offs (recovery, passcode resets, emergency access)
Lessons: communicate recovery limitations clearly; build trust with transparent security
Roadmap asks
Tokenization for emergency-contact PII, while keeping content zero-knowledge
White-label APIs for insurers/estate planners
Mobile apps and AI-assisted organization
How IH can help
Feedback on positioning and onboarding flow
Warm intros to estate planners/family offices
Security review volunteers (happy to comp)

Press release: EternaVaults Revolutionizes Digital Legacy Planning with Industry-First Zero-Knowledge Family Vault [press release link]
Thanks for reading—happy to answer anything about zero-knowledge, inheritance UX, or the build.
The zero-knowledge architecture here is genuinely impressive from a technical standpoint. Most digital legacy products are just cloud storage with a timer, but you've tackled the actual hard problems - client-side encryption with family member access and emergency protocols. The fact that 42 percent of beta users migrated to zero-knowledge mode tells you something important about trust. For distribution, focus on elder law attorneys and certified financial planners who handle estate planning - they're already having these conversations with clients but have no good technical solution to recommend.
Thank you so much for the thoughtful feedback! You're absolutely right finding that balance between security and usability has been the biggest challenge. The 42% migration rate was encouraging, but there's definitely room to improve the onboarding flow.
Really appreciate the distribution advice. I'm planning to reach out to both elder law attorneys and CFPs in my area. These conversations with clients are happening, but most advisors don't have a technical solution to recommend yet. Would love to hear if you have any specific strategies for approaching these partnerships, always learning! 🙏
This is such a thoughtful build 👏 — love how you’re tackling digital inheritance with a zero-knowledge, family-centric approach.
The combination of privacy, legacy, and usability is really powerful — especially the time-delayed access and emergency protocols.
Super interested to see how EternaVaults evolves — amazing work, Rekha! 🚀
Thank you so much for understanding my vision here and for stating it here :) Means a lot.
Are you comfortable sharing your MRR, how you came up with this idea, and how many potential customers you talked to before implementing it?
This is a really interesting idea, by the way.
Hey thank you! I came up with this idea because i needed something like this. I asked around a few people and conducted some surveys.
No MRR as yet as we are looking for funding to scale and further development. There are many more exciting things coming for this. And appreciate your feedback :)
Super awesome concept. The press article was an interesting read and your website is really well-designed.
Looking forward to following you in your growth journey :)
Thank you so much! This means a ton :)
