A financial calculator that tells you when you can stop working, built in hours, competing against free tools and spreadsheets.
The pain
The gap
Build angle
Strengths
- Real problem that people think about regularly
- Fast to build and iterate
- Could be useful as a lead magnet or feature inside another product
- Founder has already validated the concept works
Risks
- No clear monetization path. Users expect financial calculators to be free.
- Saturated market with established free competitors and paid advisors
- No defensibility. Anyone can copy the model in a weekend.
- No network effects or switching costs. Users can easily try five other tools.
- Requires distribution channel that does not exist yet. How do you get users to find this over Google's calculator or Excel?
- Regulatory risk if you give personalized advice or manage money
- Hard to charge B2B because financial advisors already have tools and banks have their own calculators

People clearly want to know when they can stop working, but many existing calculators and spreadsheets already solve this, and it is unclear if users would pay for another one.
Value Equation
Dream outcome and how likely it feels, against the time and effort it costs.
The market for financial planning tools is large but saturated with free options like Personal Capital, Mint, and spreadsheet templates, making it hard to charge enough to build a real business.
One-Person Business
Curiosity pull, identity fit, and a path from free value to paid for a solo creator.
A solo founder can build this quickly, but the skill required is basic financial modeling rather than rare expertise, so the tool itself does not create defensible advantage or recurring revenue.
Viral Frameworks
Hook strength, shareability, and how cheaply it can be tested.
The idea solves a real problem for a specific audience but lacks a clear path to distribution, monetization, or network effects that would make it grow beyond early adopters.
Builder Lens
Evidence the problem exists, timing, defensibility, and a model that fits on a napkin.
This is a feature, not a company. It could be useful inside a larger financial planning platform but does not have the scope, ambition, or defensibility that venture investors look for.

Every CEO and CFO change at US public companies, live from SEC
Built this solo. It watches SEC filings for executive and board changes, extracts the data, and shows it in real time. 2,100+ changes in the last 30 days. The comp data is interesting: average new CEO total comp is $8.4M across 284 appointments. The /explore page is fully open, no login needed.

µJS, a 5KB alternative to Htmx and Turbo with zero dependencies
I built µJS because I wanted AJAX navigation without the verbosity of HTMX or the overhead of Turbo.It intercepts links and form submissions, fetches pages via AJAX, and swaps fragments of the DOM. Single <script> tag, one call to `mu.init()`. No build step, no dependencies.Key features: patch mode (update multiple fragments in one request), SSE support, DOM morphing via idiomorph, View Transitions, prefetch on hover, polling, and full HTTP verb support on any element.At ~5KB gzipped, it's smaller than HTMX (16KB) and Turbo (25KB), and works with any backend: PHP, Python, Go, Ruby, whatever.Playground: https://mujs.org/playgroundComparison with HTMX and Turbo: https://mujs.org/comparisonAbout the project creation, why and when: https://mujs.org/aboutGitHub: https://github.com/Digicreon/muJSHappy to discuss the project.
