Our Story
One developer.
One obsession.
Zero compromises.
Concept Sandbox exists because the tools built for teams don't work for the individual creator. This is the workbench we always wanted — so we built it.
The Problem
Too many tools.
Too little progress.
As an independent consultant and indie hacker, I found myself constantly juggling tools. Raw thoughts went into Apple Notes. Requirements got formatted in Google Docs. UI prototypes lived in v0 or CodeSandbox. And somehow, the thread connecting them always snapped.
I'd have a brilliant idea at 2am, capture three bullets on my phone, and by Tuesday morning I couldn't reconstruct what I meant. The idea was dead — not because it was bad, but because the tooling killed it.
Jira, Linear, and Notion are incredible products. But they're built for collaboration. When you're a team of one, the overhead of managing a Kanban board for your own passing ideas is paralyzing. You don't need sprints — you need momentum.
“You don't need sprints — you need momentum.”
The Solution
So I built the tool I wish I'd had. A single surface where a half-baked thought can evolve — through AI-assisted structuring, through automated PRD generation, through direct handoff to prototyping tools — without ever leaving the flow.
That surface is Concept Sandbox.
“The goal isn't to manage tasks.
The goal is to move a chaotic idea into a tangible prototype as fast as humanly possible.”
The founding principle
Philosophy
Three ideas that shape everything.
The Unified Pipeline
An idea isn't separate from its PRD, and a PRD isn't separate from its prototype. They're different resolutions of the same concept. Concept Sandbox keeps them connected so you never lose the thread between tools.
Hub & Spoke
Instead of reinventing every tool, we serve as your central command center. Plan your concepts here, then launch into v0, Lovable, Bolt.new, or Replit — with your full context pre-loaded. Results flow back into the pipeline.
Built Solo, For Solo
Every design decision optimizes for the individual creator. No team management overhead, no permission matrices, no sprint ceremonies. Just you, your ideas, and the shortest possible path to a working prototype.
The Pipeline
Four stages. Zero friction.
Every concept flows through the same predictable journey — from chaotic thought to shippable prototype.
Capture
Brain dump → structured idea
Type your messy, half-formed thoughts into Quick Capture. AI extracts the signal — title, summary, tags — from the noise.
Structure
Idea → product requirements
One click transforms your bullet points into a professional PRD with user stories, requirements, and acceptance criteria.
Prototype
PRD → working code
Generate React + Tailwind scaffolding from your PRD, or launch into external tools with your context pre-loaded.
Ship
Prototype → the world
Your concept has gone from a shower thought to a shareable, interactive prototype. Archive it, iterate, or ship it.

What We Believe
Convictions, not features.
Speed Over Process
The best idea pipeline is the one with the least friction. Every feature is measured by how many seconds it shaves off your workflow.
Opinionated Simplicity
We make the choices so you don't have to. One pipeline, one flow, one interface. Constraints breed creativity.
Your Ideas, Your Data
Cloud-synced for convenience, but your intellectual property belongs to you. No training on your concepts, no data sharing. Period.
AI as Copilot, Not Captain
AI accelerates your thinking — it doesn't replace it. Every AI-generated artifact is a starting point you own and control.
Pipeline stages
AI providers
Tool integrations
Developer. That's it.
The Builder
Built by hand,
with intention.
Concept Sandbox is the work of a single developer who believes the best tools come from scratching your own itch. Every line of code, every design decision, every AI prompt — crafted with the obsessive care that only comes from building something you use every day.
No venture funding. No growth team. No bloated roadmap of features nobody asked for. Just a relentless focus on the solo creator's workflow — making the path from “what if...” to “look what I built” as short as possible.
