Recognize any of these?

You can build anything.
That is the problem.

Hacker News threads on side-project paralysis read like group therapy. The patterns are identical across thousands of engineers. The four below are the ones that actually keep shipping at zero.

11 ZOMBIE REPOS

Three projects per quarter. Zero finished.

Excitement at week one. Boredom at week three. The cycle repeats. By December: 11 stale repos and no shipped product. The pattern is not about effort. It is about not picking right the first time.

STACK-FIRST TRAP

You picked Bun + tRPC + Drizzle before you picked the user.

When you can build anything, you optimize the stack instead of the buyer. Six weekends in, the auth flow is great and nobody knows what the product does, including you. Engineering as procrastination.

FEATURE CREEP MVP

Your "MVP" has settings, themes, and a marketing site.

Engineers ship features. Founders ship outcomes. Without a hard scope and a deadline, the MVP keeps growing until energy runs out. The minimum viable product is not the minimum you are comfortable shipping. It is the minimum a buyer will pay for.

BUILDER'S YES-BOT

The agent that ships your code agrees with your idea.

Whatever you ask Claude Code or Cursor about your idea, the answer is encouraging. The same agent that helps you ship is tuned to please you. So the hole in your idea stays invisible until you have already built around it for three weeks.

The Engine

One prompt in.
30+ agents. One verdict.

The agent that helps you write Bun handlers is the same one that says “great idea!” when you ask it about your wedge. IdeaTwister is the opposite kind of agent.

Devil's Advocate first, then specialized agents that each pull your idea apart from one angle, then a scoring engine that re-ranks every direction side-by-side so the headline number is actually a discriminator. Runs on our infra. You bring an idea.

Each angle runs in parallel, not one by one, and is purpose-built to surface an opportunity you might never explore on your own. The result: systematic coverage across pricing, market position, distribution and more, in a fraction of the time.

A real engine, not a single prompt

Why our runs finish in minutes, not hours.

IdeaTwister is not a chat window calling one model. It is an engine that fires 30+ specialized agents the moment you hit start, all running side by side. Strategy agents scout nearby markets, one writes each opportunity, a Devil's Advocate stress-tests every claim, a deep-research pass builds a 13-section report on every top pick, and an action-plan writer maps out the next 30 days. They run side by side, not one after another. What would take a human consultant weeks, or a back-and-forth chat four hours, our engine finishes in minutes.

Your founder due-diligence workspace

Get the second opinion
most founders never get.

Not from friends. Not from ChatGPT prompts. From a structured founder due-diligence engine built to find weak spots, hidden risks, and better paths. Your original idea stays in the race, but it has to beat stronger nearby directions before you commit months to it. You get a verdict, the evidence behind it, and the reasons to pursue, pivot, or kill it.
