FounderClock: Billable-Hour Equivalent Tracker for SaaS Features Built vs. Revenue Generated

The Problem

Solo founders on HN and r/indiehackers regularly confess they have no idea which features they've built are actually paying for themselves — they track MRR in Stripe but never cross-reference it with the hours they spent shipping each feature. FounderClock lets founders log build time per feature alongside the revenue or retention impact that feature produced, generating a 'cost-per-feature' ledger that makes the next roadmap prioritization conversation brutally clear. It's the financial accountability layer that Notion roadmaps and Linear tickets completely lack.

Target Audience

Solo SaaS founders and indie hackers who wear both the builder and CEO hat and want to stop building features that don't move revenue

Monetization Angle

$8/mo flat; one-time $49 lifetime deal on AppSumo to seed word-of-mouth

Why Now

The 'build in public' movement has made MRR transparency normal, but nobody is being transparent about the actual labor cost per shipped feature — founders are flying blind on their own ROI.

MVP Scope

A simple time-log form where you enter feature name, hours spent, and ship date — the app pulls MRR deltas from Stripe around that date and shows a revenue-per-hour-invested card for each feature.

AI Angle

AI can optionally ingest a Linear or GitHub commit log to auto-suggest feature names and estimated hours, reducing the manual logging burden that kills retention in time-tracking tools.

Primary Risk

Founders are notoriously bad at logging time consistently, so retention depends on making the logging habit feel lighter than a time-tracker — the biggest risk is building a tool people open once and abandon.

Validation Checklist

• Tweet a simple screenshot of a 'revenue per hour invested' table for a fake SaaS and measure saves/bookmarks vs. likes as a proxy for 'I want this'
• Post on r/indiehackers asking 'Do you know which feature generated the best ROI on your time last quarter?' and gauge how many founders say they have no idea
• Build a free spreadsheet template version first and share it in the Indie Hackers community — if it gets 50+ upvotes, build the app
• Pre-sell 20 lifetime licenses at $29 before writing a line of code using a Gumroad landing page

Who Would Pay For This
