Firstten
Where your first ten customers are
Problem
The product is built and nobody is using it. The advice is to find your first ten customers, which is not advice, it is the problem restated. So the builder posts on one forum, gets nothing, and concludes the idea was bad when the idea was never tested.
Why now
Building got radically cheaper and distribution did not, so the bottleneck moved decisively. The thing that kills a project in 2026 is not the code, and the tooling is still almost entirely about the code.
Solution
Describe what you built and who it is for. It maps the specific places those people already gather and already complain about this problem: the forum threads, the communities, the search phrases, the adjacent tools' review pages. Then it gives you the ten to approach this week and what to say, in the order that costs the least credibility to get wrong.
Who it is for
A builder with a finished product and an empty user table, which after the vibe-coding wave is a very large group. They have already posted once somewhere, got nothing, and started to suspect the idea was bad. It was never tested. They do not need encouragement or another framework, they need to be told the specific ten places their people already gather, and what to say when they get there.
What you could earn from Firstten
Say you build Firstten and charge your own customers $29 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 Firstten
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 Firstten 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.
Take the context file, free
This is the AGENTS.md that keeps your coding agent on scope for the entire build: what Firstten 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.

They have already posted once somewhere, got nothing, and started to suspect the idea was bad. It was never tested. They do not need encouragement or another framework, they need to be told the specific ten places their people already gather, and what to say when they get there. ## 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. --- Context file from UpgradIQ · idea firstten · prompts kit-v4

The path to a running MVP
Foundation
Scaffold the stack, then wire the data model and sign-in. It is the skeleton Firstten stands on, and it goes up in an evening rather than a lost week of config.
The product
Build the core feature end to end, then wire how it charges. This is where Firstten finally turns into something that a stranger will actually pay you for.
Ship it
Test and harden, deploy it live, then open the launch-day toolkit that lands the first ten users who prove it.
Is Firstten for you?
- You want revenue reasonably soon, not a science project
- You can give it evenings and a couple of weekends
- You can reach Builders with a product and no customers
- You are not ready to talk to a first real customer
- You want it fully passive, with zero maintenance
- You expect it to find its own customers without you

What is free here, and what Pro unlocks
Frequently asked
Is Firstten actually validated?
It scored UIQ 83 with a GO 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?
Firstten 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 $29 a month mean?
It is the price the model suggests Firstten 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 Firstten from an empty folder to a running MVP.
