LaunchTax: Product Hunt & AppSumo Launch ROI Calculator

The Problem

Founders on r/indiehackers and HN who run Product Hunt launches or AppSumo LTD deals consistently report they have no way to calculate whether the launch actually paid off — they see spike traffic and LTD revenue but never reconcile that against the 40+ hours of prep, the support surge cost, and the long-term churn from LTD buyers. LaunchTax is a structured post-launch ROI calculator that walks founders through inputting launch prep time, ad spend, support hours burned, LTD vs. MRR revenue, and 90-day churn delta, then outputs a clear 'did this launch actually make money?' verdict with a shareable report card. It closes the loop that every 'my PH launch results' post on r/indiehackers leaves open.

Why Now

AppSumo and Product Hunt launches have become a default indie SaaS go-to-market motion in 2024-2025, but the post-launch analysis tooling is still a Twitter thread and a spreadsheet.

MVP Scope

A 15-field web form covering time cost, revenue, support load, and 30-day churn, producing a single-page ROI summary with a 'Launch Score' out of 100 and a shareable URL.

AI Angle

After the founder inputs their numbers, an LLM benchmarks their results against anonymized aggregate data from past submissions and writes a 3-sentence 'what to do differently next launch' recommendation.

Primary Risk

This is a one-time-use tool per launch, so retention is near zero — growth depends entirely on viral sharing of the report card and SEO from 'Product Hunt launch ROI' queries.

Validation Checklist

• Search r/indiehackers for 'Product Hunt launch results' threads and count how many founders admit they don't know their true ROI
• Build a public Google Sheets template for launch ROI, post it, and see if people request an automated version
• Tweet a thread asking 'did your PH launch actually make money after accounting for your time?' and measure engagement
• Check if any existing tools (Ramen, Baremetrics) have a launch-event ROI feature — if not, that's a confirmed gap

Who Would Pay For This

Likely buyers are founders, operators, and small teams with a recurring business process. Start with Indie SaaS founders who have run or are planning a Product Hunt or AppSumo launch and validate whether this can replace a spreadsheet, manual review, or consultant workflow.
