The Problem: Complexity Without Clarity
Modern life presents us with an overwhelming number of choices. From health decisions (What should I eat? Which supplements matter? How should I exercise?) to business decisions (Where should we invest? Which strategy is right? How do we prioritize?) — the cognitive burden is immense.
The result is decision fatigue: the deteriorating quality of decisions made after extended periods of decision-making. When we're mentally depleted, we either make poor choices or avoid deciding altogether — both of which carry significant costs.
Most people don't need more information. They need better systems for processing the information they already have.
“The four major killers — cardiovascular disease, cancer, neurodegeneration, and metabolic dysfunction — share common root causes that are largely preventable. The strategies that address one typically benefit all four.”— Dr. Peter Attia, longevity physician and author of Outlive (2023)
A Different Approach to Decision-Making
StackFast takes a different approach: instead of giving you more options, we help you reduce the number of decisions you need to make by identifying what actually matters in your specific situation.
Our AI-powered analysis synthesizes evidence, identifies gaps, and creates clear action paths — so you spend less time researching and more time executing on what works.

Key Concepts
What is Decision Intelligence?
Decision Intelligence is the discipline of transforming complex decisions into clear, actionable plans through systematic analysis and AI-powered insights. Unlike traditional decision-making that relies on intuition alone, Decision Intelligence reduces cognitive load and improves outcomes by identifying what actually matters. According to Gartner (2024), organizations using Decision Intelligence report 25% faster decision cycles and 40% reduction in decision fatigue among leadership teams.

What is decision fatigue and why does it matter?
Decision fatigue is the deteriorating quality of decisions made after a long session of decision-making. Research published in the Proceedings of the National Academy of Sciences found that judges granted parole in 65% of cases heard early in the day, but nearly 0% in cases heard late in the day. The average adult makes approximately 35,000 decisions daily, with each decision depleting mental resources. StackFast addresses decision fatigue by reducing unnecessary choices and creating clear action paths.

What are the Four Horsemen of health?
The Four Horsemen of health are the four chronic disease categories responsible for 80% of deaths in developed nations: cardiovascular disease, cancer, neurodegeneration (including Alzheimer's and dementia), and metabolic dysfunction (including type 2 diabetes). According to the Lancet (2024), up to 45% of these conditions are preventable through lifestyle intervention. These conditions share common root causes including insulin resistance, chronic inflammation, and mitochondrial dysfunction — which is why addressing them systematically produces better outcomes than treating them separately.
