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.

Decision Quality Index

Excellent — 3 biases detected

In 2014, Tesla announced the Gigafactory — a $5 billion battery manufacturing facility that would produce more lithium-ion batteries annually than the entire world's 2013 output. The decision to vertically integrate battery production (with Panasonic as partner) was considered reckless by automotive analysts. Battery costs were the primary barrier to EV adoption, and Tesla bet that manufacturing scale would drive costs below $100/kWh. By 2020, Tesla achieved this target and became the world's most valuable automaker.

Decision context

Whether to invest $5B in vertically integrated battery manufacturing at unprecedented scale, or continue purchasing batteries from third-party suppliers like every other automaker.

Deep hindsight-stripped analysis coming soon. This case is part of our ongoing backfill to reconstruct what the platform would have flagged at decision time. The summary and bias profile below are drawn from primary sources.

Lessons learned

Overconfidence bias was present and arguably necessary — no one without extreme conviction would have committed $5B to an unproven manufacturing concept. But the underlying physics-based analysis was sound.
Planning fallacy was severe (the Gigafactory was years late and billions over budget) but the strategic direction was correct, and Tesla maintained sufficient capital to survive the delays.
Survivorship risk is high: Tesla nearly went bankrupt multiple times during 2017-2019 "production hell." The success is real, but the path was far riskier than it appears in hindsight.
