How is sensitive data protected?

All documents are encrypted with AES-256-GCM at rest and TLS 1.3 in transit. A GDPR anonymization layer removes PII before any AI processing. Your data never leaves our SOC 2 certified infrastructure.

How long does integration take?

Less than 30 minutes. Upload documents directly, connect via OAuth for Slack, or use our REST API for bulk processing.

How does outcome tracking work?

Outcomes are detected automatically from follow-up documents, Slack messages, and web intelligence. You confirm with one click. Each reported outcome makes your future analyses more accurate.

How is Decision Intel different from ChatGPT?

ChatGPT gives one opinion from one model. Decision Intel uses 3 independent judges for noise measurement, a 20×20 bias interaction matrix for compound scoring, 31 domain-specific biases, and an outcome flywheel that gets smarter with every decision.

Critical — 5 biases detected, 2 toxic combinations

Groupon rejected Google's $6B acquisition offer and IPO'd at a $13B valuation. The daily deals model proved unsustainable as merchants saw no repeat customers, and Groupon's accounting metrics were questioned by the SEC. The company lost 90%+ of its market cap.

Decision context

Lessons learned

Recency bias: explosive 2010-2011 growth was extrapolated as the new normal rather than a novelty-driven spike
Anchoring to the $6B Google offer as a floor rather than treating it as a genuine exit opportunity
Daily deals failed because they attracted deal-seekers who never became regular customers — the business model had negative retention
