About this appAI proposal
Pennyjar gives bloggers and newsletter writers a way to be paid by readers who will not take a full subscription. Readers can leave a one-off tip, pay $1 a month or $10 a year, or fill a yearly jar that is shared among the writers they read.
Writers add a support page and a small button to their posts. Readers pay without a long sign-up. Nothing is locked, so free readers stay, and those who want to give have a simple way to do it.
Unlike subscription-only platforms, Pennyjar treats small, casual support as the main product. It works next to your existing blog or newsletter.
- Tagline
- Let readers say thanks, a little at a time.

- Why this name
- Pennyjar is two plain words: small coins and a jar. It suggests casual, low-pressure giving, not a subscription.
In the first version

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
- Shared outputs. Each writer gets a public support page and a thank-you button for posts and newsletter footers. Readers who see it can tip in a few taps, and a writer who is also a reader may open their own jar.
- Do they become customers?
- Readers who tip see Pennyjar but may never become creators. To test: how many tipping readers open a jar for other writers, and how many of those writers sign up themselves.
- First customers
- Independent newsletter writers and bloggers with a free audience and no paid tier, starting with one niche such as technical writing.
- Where to reach them
- Hacker News and forums: Share the idea where readers asked for in-between payment options, and invite writers to a pilot.
- Direct writer outreach: Email free-newsletter authors offering a hosted support page set up for them in ten minutes.
- Writer communities: Post a short case study from pilot writers in newsletter and indie blogging groups.
- First milestone
- Ten writers with a live support page, and at least 3% of their active readers giving something within 60 days.
Why people already pay for this
- Public claimReaders want to support creators but lack simple payment options between free and high-commitment subscriptions
- AI inferenceAudiences would use small recurring payment options ($1/month, $10/year) for content they value
- Public claimA tip-jar distribution model based on readership could be effective for newsletters
- Public claimSubstack and Medium are positioned as potential platforms to implement flexible micropayment options

RisksAI inference
- CommercialReaders may say they would give but not do so. The evidence of demand is a public claim and an inference, not measured behavior.
- RegulatoryHolding funds and paying out many small shares may bring money-transmission, tax-form and cross-border payout rules.
- TechnicalCard fees can swallow a $1 payment. Batching charges and yearly billing are needed to keep margins.
- DataSplitting a jar by readership needs reading data across sites, which raises privacy concerns and may be hard to collect or trust.
- PlatformSubstack or Medium could add their own tipping, and may limit embeds or links in their posts.
