Why It Matters

The Blind Spot That Kills Startups

Most tools only score "potential." But 35% of startups fail because they aren't ready—not because the idea is bad.

Frequently Asked Questions

How long does a GemScore evaluation take?

Screening: 3-5 minutes. Assessment: ~15 minutes. Verification: ~30 minutes. Time depends on complexity and web research required.

What information do I need to provide?

You can either fill out our structured questionnaire (covering problem, solution, market, team, traction), or upload a pitch deck (PDF), images, or voice notes. The more context you provide, the more accurate the evaluation.

Can I share my GemScore report with investors?

Absolutely. Every report has a unique shareable link. You can also export it as PDF, copy sections directly, or embed it in your data room. You control visibility and can add password protection.

How is this different from ChatGPT or other AI chatbots?

"ChatGPT gives answers. Athanor gives artifacts." Same inputs, every time: IC-ready memo, not a conversation.

  • Verification: We cross-check claims with live web data.
  • Methodology: Fixed 5-agent pipeline + adversarial debate.
  • Output: Calibrated scores with confidence intervals.
  • Format: Shareable brief ready for investors.

What's the difference between Screening, Assessment, and Verification?

Screening (Free Daily): Potential score only, 4 agents, 3-5 min.
Assessment ($39): Dual-axis, 5 agents + Validation, adversarial debate.
Verification ($199): All Assessment features plus Deep Verification, Entity Graph. View full comparison →

Is my idea confidential and secure?

Yes. Your data is private by default. We do not train public AI models on your submissions. Only you can see your report unless you explicitly share the link. Password protection available.

Can I re-evaluate after making improvements?

Yes. Re-run anytime you have credits. Track progress—watch your Readiness score climb from 18 → 45 → 70 as you hit milestones. We're building a "diff mode" to show changes between runs.

What is the Live Builder?

Live Builder is a conversational way to fill out the evaluation form. Chat with Marcus—an AI assistant who asks questions and fills the form for you. Supports voice and text input. Free during promo period.
