Preuve AI

Source-linked validation for founders

Frameworks that operate on live data, not text in. Every claim links back to a verifiable source.

I built Preuve AI because the structured-frameworks-on-AI-input pattern is the most common failure mode in this category. Preuve scans 40+ live sources (Crunchbase, Google Trends, Reddit, Product Hunt, G2) and links every competitor, market size estimate, and demand signal back to its origin before applying any framework. The published 6-framework scoring runs against real data, not against the model that rated it. The median score across 4,000+ ideas is around 50 (not 82) and only 18.3% of ideas earn a go verdict.

  • Free viability scan
  • $29 one-time report
  • Source-linked claims

Best for: Founders who want frameworks fed by live market data
Skip if: You only want a SWOT slide for a pitch deck

02

DimeADozen

Long-form report instead of frameworks

If you wanted VenturusAI for output volume, DimeADozen does the same job in PDF format with more market analysis.

DimeADozen replaces structured frameworks with a 40+ page narrative report - market analysis, competitor maps, capital readiness, growth advice. Closer to a research-style document, weaker on framework rigor. Same source-linking gap: the competitor names and market sizes inside the PDF are AI-generated and not traceable to live data.

  • Free business overview
  • $45 bundle
  • No source links

Best for: Founders who want a long PDF to share with stakeholders
Skip if: You need verifiable claims, not document length

03

IdeaProof

Broad startup toolkit

IdeaProof bundles validation, business plans, branding, and marketing assets. Wider scope than VenturusAI's framework focus.

IdeaProof is more breadth than VenturusAI - validation is one of several modules alongside branding, ad copy, and business planning. The "89% accuracy" claim has no published methodology. Better fit if you want assets in addition to analysis.

  • 70 free credits (~2 validations)
  • From €19 (credit-based)
  • No source links

Best for: Founders who want validation plus brand and marketing assets
Skip if: You want verifiable validation, not a broader asset suite

04

IdeaBuddy

Business planning, not validation

If you wanted VenturusAI for the pitch deck output, IdeaBuddy gives you a more developed planning canvas instead.

IdeaBuddy is a $15-$55/mo planning suite with Canvas, Financial Plan, and Business Plan Builder. Less framework-heavy than VenturusAI, more focused on the document. The validation module is questionnaire-based and IdeaBuddy's ToS Section 4 explicitly disclaims ChatGPT accuracy. Same input problem, different output shape.

  • 15-day free trial, no card
  • $15-$55/mo across 3 tiers
  • No source links

Best for: Founders past validation who want a structured plan
Skip if: You still do not know whether anyone wants this

05

ValidatorAI

Conversational feedback

Val chats. More honest about being a thinking partner than VenturusAI's framework framing.

ValidatorAI does not pretend to be a research engine. The conversational mentor framing is upfront. If you wanted VenturusAI for early-stage feedback rather than a structured deliverable, Val covers that with less ceremony. Treat it as a sparring partner.

  • Free quick feedback
  • $49 for 3 sessions
  • No source links

Best for: Quick conversational feedback during idea exploration
Skip if: You are past brainstorming and need defensible evidence

06

WorthBuild

SaaS-focused with lead discovery

Narrower SaaS focus than VenturusAI, with a built-in lead discovery layer (Reddit, HN, Twitter).

WorthBuild is worth reviewing if your idea is SaaS and you want lead discovery alongside the validation report. $5 per report (or $20 for 5) versus VenturusAI's subscription model. Methodology is not published either, but the lead discovery angle is genuinely differentiating.

  • 1 free validation/month, no card
  • $5/report or $20 for 5 reports
  • No source links

Best for: Solo founders validating a SaaS idea who want first-customer leads
Skip if: Your idea is hardware, marketplace, agency, or non-SaaS

07

ChatGPT

Free brainstorming partner

If you only need a SWOT or Porter's analysis on text input, ChatGPT does that for free or $20/mo.

ChatGPT and Claude can run SWOT, PESTEL, or Porter's 5 Forces on a text description for free or $20/mo. The use case overlaps directly with VenturusAI's core flow. The same limitation applies: text in, framework text out, no live data layer. Use it to generate questions, then use real market data to answer them.

  • Free tier
  • Free or $20/mo
  • No source links

Best for: Free MBA-framework analysis on idea descriptions
Skip if: You will trust any number it gives you without checking
