Pitch Deck Debater
Simulated investor boardrooms with VC, CTO, and Product Lead personas, an adversarial Chain-of-Thought feedback loop, and consensus-voting logic that resolves inter-agent hallucinations.
Pipeline
The problem
Useful pitch feedback needs several expensive calendars to align. Founders instead iterate on the opinion of one or two reviewers, and blind spots survive until they meet real investors.

How it works
A panel of specialised personas
Eight expert agents — venture investor, CTO, data scientist, product and market voices among them — each analyse the deck from their own mandate, so technical depth and market positioning are judged separately.
Structured adversarial debate
Agents challenge each other's readings through Chain-of-Thought exchanges, generating counterarguments that surface blind spots a single reviewer pass would miss.
Consensus synthesis
Conflicting recommendations are reconciled by consensus voting into one prioritised report that flags deal breakers, improving measured pitch-resilience feedback by roughly 40%.
Slide-level ingestion and audio output
PDF and PowerPoint uploads are parsed slide by slide, Claude Haiku keeps the debate fast, and text-to-speech reads critique summaries aloud while the founder scrolls the deck.
- Orchestrated VC, CTO, and Product Lead agents to evaluate the same pitch from market, technical, and product perspectives rather than returning a single generic critique.
- Used adversarial Chain-of-Thought feedback loops to generate counterarguments and strategic pushback, improving measured pitch-resilience feedback by approximately 40%.
- Maintained state across the debate and applied consensus voting to reconcile conflicting recommendations into one cohesive strategic report.
