ONLY 100 METRICS MATTER

Companies track thousands of numbers, but almost none of them change decisions. In reality, about 100 metrics explain 90% of what's happening. Once you break the business into equations - growth, engagement, revenue - you see which levers actually matter. Everything else lives in the long tail: useful for edge cases, not for running the company.

WHY WE BUY: THE OMISSION BIAS

People judge harmful actions more harshly than harmful inactions - this is known as the “Omission Bias.” Buying feels riskier than not buying because action carries blame if it backfires. Amazon and others flip that bias by showing the cost of doing nothing. When inaction feels like “the bad decision” - whether it's a higher cart price, lost ROI, or missed deal - spending suddenly feels like the safer move.

PRIORITIZATION STARTS WITH STRATEGY

Most teams treat prioritization as a to-do list problem when it's really a strategy problem. Every decision about what's “valuable” reflects a bet on where leverage lives and where decay is setting in. The real work is mapping the forces at play: what increases or protects revenue, what reduces or protects cost, and which advantages will actually last. Once you see those dynamics, prioritization stops being about urgency and starts being about power.

ANTHROPIC IS CATCHING UP WITH OPENAI

Anthropic quietly went from $1B to nearly $7B in run-rate revenue this year, a six-fold jump that puts it within striking distance of OpenAI. While OpenAI dominates headlines, Anthropic's API-driven business is growing faster and more efficiently, relying less on free users and more on enterprise integrations. Beneath the public fights about AI ethics and regulation, the real story is simpler: Anthropic might actually win on execution.
