The solo founder’s startup checklist: 7 stages from idea to scale
200+ milestones. 7 stages. 1 framework. Built for founders who build with AI tools like Cursor, Lovable, and Claude Code.
Solo founders and vibe coders build fast. Cursor, Lovable, v0, Claude Code: the tools to go from idea to deployed product in a weekend exist today. But speed creates a new problem. You can ship before you know if you should.
Most startup checklists are built for teams with a CTO, a head of growth, and a board. They assume resources you do not have and stages you might never reach. This framework is different. It is built for one person building one thing, often with AI tools, often at 2 AM.
The key insight is not "check more boxes." It is this: founders progress unevenly. You might have a polished product (Stage 3) with zero distribution (Stage 1). Revenue (Stage 4) with no analytics (Stage 2). A project that has revenue but zero analytics is not at Stage 4. It is a Stage 4 facade on Stage 2 foundations. That is exactly the kind of blind spot this framework, and Banast, is designed to catch.
This page maps out all 7 stages. Each stage has its own detailed checklist. The goal is not to rush through them. It is to know where you actually stand.
The 7 stages at a glance
“Is this a real problem?”
An idea with notes or research, but nothing built yet.
“Can I simulate value, even manually?”
Demand validated with prospects or network via manual flows.
“Can someone use this alone, without your help?”
A first working version, but no real users yet.
“Will someone pay for this?”
Product is public, first users and revenue. Focus: distribute and learn, not build.
“Do they come back and pay without me pushing?”
Retention is stable, revenue grows steadily. Focus: retention and churn, not acquisition.
“Can I scale what works?”
Fit validated. Self-serve complete, multiple channels, predictable CAC. Time to scale.
“Can it run without just me?”
Growth is predictable. Focus shifts to team, process, governance, and expansion.
Why checklists fail: the inconsistency problem
Most founders progress unevenly. They are advanced in one domain and behind in another. This is natural. But it is also dangerous when you do not see it.
A project with revenue but no analytics is not at Stage 4. It is fragile. A project with a perfect product but zero distribution is invisible. A project with enterprise deals but startup-level legal is a ticking clock.
Traditional checklists treat each item independently. This framework treats them as a system. The value is not in knowing what you have done. It is in seeing where you are out of balance.
Banast detects these imbalances automatically and flags them as priority blind spots in your audit report.

Frequently asked questions
What are the 7 stages of a startup?
Idea (validate the problem), Proof of Concept (simulate value manually), Prototype (build a working version), MVP (get first paying customer), Product-Market Fit (prove retention), Growth (scale what works), and Scale (build an organization). Each stage has specific milestones organized by category.
How do I know what stage my startup is at?
It is rarely linear. A project can have milestones from different stages completed simultaneously. The real question is not "what stage am I at?" but "where am I out of balance?" Banast detects this automatically by evaluating milestones across all 7 stages.
What is a solo founder startup checklist?
A framework of milestones designed specifically for founders building alone, often with AI tools. Unlike corporate checklists that assume teams and budgets, this framework focuses on what one person can validate, build, and ship.
What is a vibe coder?
A founder who builds products primarily using AI coding tools like Cursor, Lovable, v0, or Claude Code. Vibe coders can ship fast but often lack the strategic framework to know what to build next. This checklist fills that gap.
How does Banast use this framework?
Banast uses the Milestone Matrix as the backbone of its AI audit. It evaluates your project against 200+ milestones across all 7 stages, detects your current stage, identifies cross-stage inconsistencies, and generates a scored report with specific recommendations.
