Five AI specialist agents evaluate a startup. They debate. A final judge scores it 0–100. You get an evidence-backed report in 15 minutes — not 3 weeks.
A deck, a call, a gut feel. That's what most early-stage decisions run on.
Athanor replaces the guess with structure: five specialist agents, a live debate between them, and a final score you can audit.
GemScore. Evidence-backed. Manipulation-resistant. Ready in 15 minutes.
GemSeeker assigns a specialist agent to each dimension of a startup.
Opportunity size, competitive dynamics, timing
Founder-market fit, track record, execution signals
Traction, technical feasibility, differentiation
Model viability, unit economics, capital efficiency
Red flags, scenario stress, manipulation signals
They run in parallel. Then they debate each other's conclusions. A Judge synthesizes and issues the GemScore — a calibrated 0–100 rating with evidence citations, flag severity, and a structured breakdown you can audit.
Not opinion. Not a vibe. A score you can defend.
Infrastructure
The same engine. Available as infrastructure for your investment workflow.
Whether you screen 5 deals a month or 500, Athanor OS puts the GemSeeker engine in your stack — SDK access, custom pipelines, white-label — built for the teams who can't afford noise in their deal flow.
What founders and investors say after running an evaluation.
"I recently used Athanor Market to assess our startup concept, and the experience was genuinely helpful. The dual-axis GemScore gave us a clear snapshot of both our current readiness for investors and the realistic upside we could achieve if we execute well. The expert feedback from the Circle of Alchemists pointed out blind spots we hadn't considered, saving us weeks of guesswork."
Mikhail
Founder
"I've been really impressed with Athanor so far. The idea of having an AI-native copilot for pre-due diligence is incredibly useful, especially at the early stages where clarity and structured thinking matter most. The GemScore system stands out — separating Readiness and Potential is a smart way to evaluate startups without oversimplifying them into a single number. It actually reflects how investors think."
Dan Reiner
Investor
"I tested the product on my own idea and was really satisfied with the result. The analysis feels structured, professional, and much more grounded than a typical LLM chat. It helped me see both the strengths and weak points of the idea and made me want to run it again with a more thoughtful input. I also liked the detailed AI analysis logging, the debate flow, and the potential/readiness matrix."

"What drew me to Athanor was its structured approach. As an operations manager, I value tools that help turn a project from a loose set of ideas into something more clear and complete, with visible risks and areas that need more work."
Gero
Operations Manager
"The combination of an evaluation layer with milestone-based execution makes this a genuinely useful tool for early-stage diligence."

"The free monthly evaluation makes it easy to get a feel for the product. Once I ran it, I understood immediately why investors would find this useful."
