Problem

A course sells with a thirty-day guarantee. Someone finishes the whole thing on day twenty-eight and asks for their money back. The seller either pays and feels robbed or refuses and gets a public complaint. There is no policy that survives contact with either outcome.

Why now

Nothing changed. This is a long-standing problem in a category that has been well served for a decade, which is most of why it scores CAUTION.

Solution

Tie the guarantee to progress rather than to the calendar. The refund terms are stated up front against completion, the buyer sees exactly where they stand, and the seller's decision is a rule they published rather than a mood.

Who it is for

An independent course seller with a guarantee they have come to resent. Someone finishes the entire course on day twenty-eight of a thirty-day window and asks for their money back, and there is no good move: pay and feel robbed, or refuse and get a public complaint. No policy written on a mood survives either outcome.

What you could earn from Cohortpay

Say you build Cohortpay and charge your own customers $25 a month, the price the score suggests. The numbers below are the revenue that would come from them. This is money you earn, never a fee you pay UpgradIQ, and we never take a cut. It is arithmetic off the price, not a promise the customers arrive on their own.

Your build kit for Cohortpay

Start the build and the kit opens two steps in, then drip-feeds the rest one phase at a time. Every phase is a copy-paste prompt for your agent with its own verification before the next unlocks, so Cohortpay moves from an empty folder to a running MVP without you ever holding the whole plan in your head.

Progress saves across every device, and the workspace always reopens on the exact step you left, so a build that runs over several weeks survives them instead of dying in a browser tab you eventually close.

How you actually build it

Connect your coding agent once. It pulls the current phase straight from your kit over MCP: the exact prompt, the outcome to aim for, and the check to run before it moves on. You review and ship, it does the typing.

No copy-paste juggling, no thread to lose. The kit stays the single source of truth, and your agent works through it one phase at a time, verifying its own work at each step before the next phase is unlocked.

Start free, run phase 1Free account, no card. The first phase prompt unlocks the moment you start, right in your workspace.

Phase 3 of 10: Scaffold the stack
Outcome: The project builds, runs locally, and its health route answers 200.
Check: Run the dev server. `curl` the health route and show the 200. Run the build and show it passing with zero type errors. Confirm `.env` is gitignored: `git status` must not list it.

This is the AGENTS.md that keeps your coding agent on scope for the entire build: what Cohortpay is, who it is for, the stack, the non-goals, and the rules it must follow. Copy it into your project now, no account needed, and your agent is briefed before you write a line.

# Cohortpay

Course refunds without the drama

## What this is
Tie the guarantee to progress rather than to the calendar. The refund terms are stated up front against completion, the buyer sees exactly where they stand, and the seller's decision is a rule they published rather than a mood.

## The problem it solves
A course sells with a thirty-day guarantee. Someone finishes the whole thing on day twenty-eight and asks for their money back. The seller either pays and feels robbed or refuses and gets a public complaint. There is no policy that survives contact with either outcome.

## Who it is for
An independent course seller with a guarantee they have come to resent. Someone finishes the entire course on day twenty-eight of a thirty-day window and asks for their money back, and there is no good move: pay and feel robbed, or refuse and get a public complaint. No policy written on a mood survives either outcome.

## Stack
Next.js + Postgres

## Non-goals
Do not build features outside the core job above. This product exists to do one
thing well. Every extra feature is a reason it does not ship.


## Rules for the agent
- Build one phase at a time. Do not run ahead into later phases.
- Validate input at every boundary where data enters.
- Never put a permission or plan check in client code.
- Ask before adding a dependency that a few lines would cover.
- If something is ambiguous, say so rather than inventing a requirement.

The path to a running MVP

Phases 1-4

Foundation

Scaffold the stack, then wire the data model and sign-in. It is the skeleton Cohortpay stands on, and it goes up in an evening rather than a lost week of config.

Phases 5-6

The product

Build the core feature end to end, then wire how it charges. This is where Cohortpay finally turns into something that a stranger will actually pay you for.

Phases 7-10

Ship it

Test and harden, deploy it live, then open the launch-day toolkit that lands the first ten users who prove it.

Is Cohortpay for you?

A good fit if
  • You want revenue reasonably soon, not a science project
  • You can give it evenings and a couple of weekends
  • You can reach Independent course sellers

Frequently asked

Is Cohortpay actually validated?

It scored UIQ 73 with a CAUTION verdict, weighed across eight sub-scores on the same rubric as every idea. GO means 75 and above, so demand and buildability were judged, not guessed.

What stack does it use?

Cohortpay is built on Next.js + Postgres, chosen because a coding agent can carry most of it. You are not fighting infrastructure, you are shipping the feature that matters.

How long to a running MVP?

The kit is ten phases, drip-fed one at a time so you always know the single next step. An evening and a weekend for the lighter builds, a few focused weeks for the deeper ones.

What does the $25 a month mean?

It is the price the model suggests Cohortpay could charge its own customers, not a fee to us. It is here so the money question is answered before you build, not after.

Which agent do I need?

Any capable coding agent: Claude Code, Cursor, Lovable, or Bolt. Every phase is a copy-paste prompt with its own check, so the agent does the typing and you keep the judgement.

What is free versus Pro?

The whole case above is free: the problem, timing, solution, buyer, and the full score. Pro adds how it makes money, the one risk that could kill it, and the full kit that carries Cohortpay from an empty folder to a running MVP.
