GoNoGo vs DimeADozen

We are one of the two, so here is the rule we held ourselves to: the section on when to pick DimeADozen is written to be useful to you, not to be survivable for us.

Short answer

GoNoGo or DimeADozen?

DimeADozen answers in minutes from a written description, for $9 starter, $129 full. GoNoGo asks for a 15-minute conversation first, then runs six research stages and scores the result against fixed thresholds. Speed against input depth, and the right answer depends on how decided you already are.

The split in four lines

  1. Screening several ideas: DimeADozen
  2. One idea you are about to build: GoNoGo
  3. Needing a document for someone else: DimeADozen, on citation count
  4. Wanting your own reasoning interrogated rather than summarised: GoNoGo

Side by side

Price and speed first, then the axes that actually decide which answer you get. Their column is read off their own product page on 16 August 2026.

How your idea gets inWritten description, optional file uploadA 15-minute spoken interview with a video avatar that asks follow-ups
How much of your reasoning reaches the researchA description plus any files you attach13 fields of 14 filled from the conversation: median 1,616 characters of your own words against 163 from a single idea field, measured across 26 projects
What else you can bring"Add files that describe your business idea"Drop files into the session while you talk: text, CSV, spreadsheets, PDFs, images. Each upload is then graded before it is used, with its category, a reliability tier, the limitations of that kind of evidence and the sample size it represents, so a survey of nine friends is not treated as market data
Synthetic audienceNot mentionedA panel built from real posts across 11 platforms, calibrated by holding back part of the data and checking the personas against it
What checks the outputCitation volume: "verifiable, not LLM-hallucinated"Key claims re-checked by three independent models from three vendors (Anthropic, Mistral, Amazon); disagreement is recorded by name rather than averaged away
How the verdict is formedTested against what comparable companies have provenComputed: five researched dimensions scored against fixed thresholds, verdict is a threshold on the sum (70+ go, 50+ pivot)
What you get afterwardsA 150+ page report with 1,200+ URL citations across 100+ named sources21 documents from three agents. Alex: 15, including the validation report, market intelligence, problem dossier, investor pitch deck guide, pitch one-pager, go-to-market playbook, customer economics and the focus-group interviews. Sam: what to build, on what, in what order, and what it costs. Maya: brand book, design system, logo, MVP builder prompt, and a landing page you can publish to start collecting leads
After the verdictNot mentionedA daily digest built for your project specifically: news in your niche, your named competitors, and it is aimed at your still-unproven assumptions and the concerns your focus group raised, rather than at the market in general
Contact with real humansNoneReality Check: a real survey of the real people your landing page collected, scored against what the synthetic panel predicted

The axis DimeADozen does not have: a conversation

Every tool in this category, DimeADozen included, starts from something you typed. Ours starts from something you said, to a video avatar that asks the next question based on your last answer, in any of 21 languages, for about half an hour.

It is full duplex, which matters more than it sounds: you can cut in mid-sentence and it stops and listens rather than talking over you, and it does not abandon a thought because you paused to think. That is the difference between an interview and a form read aloud.

Why bother. In a randomised experiment on 1,001 people, spoken answers ran 2.5 times longer than typed ones to the same question (Höhne, 2024, Social Science Computer Review 42(4)). On our side, 13 of 34 projects were carried through all four phases, so people do not abandon it at minute two.

And what we are not claiming, because the evidence goes the other way: that speaking makes people more honest, or that a realistic avatar makes them more open. Both have been tested and both failed. The case for voice is volume of context, not candour.

Pick DimeADozen

You need a document that survives being forwarded: a co-founder, an investor, a spouse who wants to know why you are quitting your job. Compare on citation count and they win it.

  • Citation density: the highest of anything we checked
  • Cohort retention curves pulled from public filings rather than estimated
  • Built to be shown to someone else, which is a real product decision

Pick GoNoGo

You need the decision itself, not the artefact of the decision. Fifteen minutes of conversation, six research stages, and a verdict on thresholds: 70 and above is go, 50 and above is pivot.

  • The interview pushes back while you are still describing the idea
  • Claims are checked by three independent models and disagreement is recorded by name
  • The verdict moves when the evidence moves, not when the model is in a better mood

What neither of us does

Neither tool talks to your actual customers. Both are ways to think faster before you go outside, and both are useless against the most common cause of death, which is the founder losing interest in month four.

Common questions

Is GoNoGo better than DimeADozen?

Not in general, and the honest answer depends on one thing: how much you have already decided. You need a document that survives being forwarded: a co-founder, an investor, a spouse who wants to know why you are quitting your job. Compare on citation count and they win it. If instead you have picked one idea and are about to spend months on it, the depth of the input starts to matter more than the speed of the output, and that is the case we built for.

How much does each cost?

DimeADozen: $9 starter, $129 full (read off their own page on 16 August 2026). GoNoGo: a free tier, then $9.99-19.99 per project. Neither is a subscription you have to cancel.

What does GoNoGo do that DimeADozen does not?

It interviews you first. A 15-minute conversation puts a median of 1,616 characters of the founder's own words into the research against 163 from a single idea field, measured across 26 projects. Then six research stages run on that, and the verdict is computed against fixed thresholds rather than composed as an opinion.

What does DimeADozen do that GoNoGo does not?

Citation density: the highest of anything we checked. Cohort retention curves pulled from public filings rather than estimated. Built to be shown to someone else, which is a real product decision.
