About this appAI proposal
Hearthbook is a private notebook for the people in your life. Save birthdays, what they like, what you talked about last, and what is happening in their lives. Before you meet or call someone, open their page and see it all in one place.
It is for individuals who want to keep up with friends, family and casual business contacts without a spreadsheet or a scatter of notes. Reminders are tied to moments, such as a job interview next week or a new baby, not only dates.
Unlike a phone contact list, it keeps history and context. Your notes are yours, can be exported at any time, and are never shown to the people they are about.

- Why this name
- A hearth is where people gather and stay warm. Short, pronounceable, and it suggests tending something over time. Needs a trademark check.

What it could be worthEstimate
What a software business making this much sells for today, from real deals. Pick a monthly revenue.
If it makes
Worth about
$194,000
Sale range $132,000 to $263,000
$120,000 a year in revenue
From 87 software businesses listed and sold on Empire Flippers in the last year, revenue vetted by the broker: they sell for about 19× their monthly revenue, most between 13× and 26×.
Measured on profit, the middle deal is 32× monthly net profit: about 2.7 years of profit.
An estimate, not an offer or financial advice. A real price depends on profit, growth, churn, how much of the work is the owner's, and the buyer.
How it would growAI proposal
How the product would reach new customers through its own use, and how the first ones would be found. A plan to test, not a result.
- Built-in loop
- No loop in the product. Used privately by one person about their contacts, so there is no built-in sharing loop. Growth would come from content, search and word of mouth.
- Do they become customers?
- Nothing reaches non-users by design. Test whether content about keeping in touch turns visitors into free signups, and free users into paid.
- First customers
- Independent professionals such as freelancers and consultants who keep many casual business and personal contacts and already use notes apps for them.
- Where to reach them
- Productivity communities: Share a free template and walkthrough in forums and groups about note-taking and personal knowledge management.
- Search content: Publish guides on remembering birthdays and keeping in touch, linking to the free tier.
- Open-source users: Reach people who follow self-hosted personal CRM projects and want a hosted, simpler option.
- First milestone
- Fifty free signups from freelancers and ten of them paying for Plus within 60 days of launch.
Why people already pay for this
- VerifiedGitHub repository gained 25495 stars in 3530 days

RisksAI inference
- CommercialMany people may not pay for relationship tracking; free tools and phone notes are the real alternative. Willingness to pay is untested.
- PlatformWeb push on phones is less reliable than native apps, and missed reminders would undermine the core promise.
- DataNotes about other people are sensitive. A breach or unclear privacy terms would harm trust, and privacy law may apply.
- CommercialHabit is hard: users may stop logging notes after a few weeks, which hurts retention.
- TechnicalImport from phone contacts is limited in a PWA, so setup may be slower than in a native app.
