Train the systems beneath cognition.

Most people track the signals. Few know what they mean for cognitive performance.

Growth Factor Method maps the upstream physiological systems most likely constraining cognitive output, then translates that pattern into a focused performance protocol — built for executives, founders, serious athletes, and performance-minded adults.

Map Reviews are open for a limited number of clients · 1:1 fit conversation required

Measure accurately · Train deliberately · Perform reliably
Who It's For

Built for people whose performance has a scoreboard.

Executives & Founders

Your output is decision quality and sustained focus. GFM helps identify which upstream systems may be constraining both.

Serious Athletes

Training is dialed, results are inconsistent. Recovery, readiness, and tracking under load may hold the missing pattern.

Parents of Serious Youth Athletes

Talented but inconsistent between practice and competition. A measured, non‑diagnostic look at focus and readiness — discussed with you first.

Wearable Users & High Performers

You have years of Oura, Whoop, or Garmin data. GFM helps translate what those signals may mean for how you actually think and perform.

Cognitive Constraint Map

The systems beneath, mapped to performance.

This map is the core of what you receive: a reviewed picture of which systems beneath cognition may be shaping your focus, reaction speed, working memory, executive control, sustained performance, and visual tracking — and where to train first. Line weight reflects evidence-informed relationship strength, then gets individualized through operator review.

Line weights represent evidence-informed relationship strength and are individualized after operator review. They are not measured individual correlations or diagnostic claims.

Systems Beneath Cognition

Five systems beneath cognition.
Find the constraint pattern beneath performance.

Performance outputs are shaped by the physiological systems beneath them. GFM reviews wearable trends, readiness context, and operator interpretation to identify the most likely constraint pattern and translate it into a focused, personalized protocol.

Ways to Work Together

Two ways to work with GFM.

Both paths begin with a 1:1. GFM maps how systems beneath cognition may be constraining performance, then, if you continue, builds a protocol targeting the upstream physiological systems most likely affecting downstream cognitive output.

Cognitive Constraint Map

Limited Review Capacity
Limited availability · review-led assessment

Both paths begin with a 1:1 fit conversation. Application-style intake, no checkout required.

A 1:1 reviewed assessment — not an app, not another dashboard. You complete a measured cognitive battery, share wearable and readiness context where available, and walk away with a reviewed map of what may be constraining your performance and what to train first.

  • Six-task cognitive battery — a measured baseline, not self-report
  • Wearable / readiness context review (Oura, Whoop, Garmin, Apple Watch)
  • Your Cognitive Constraint Map, operator reviewed
  • Written performance snapshot
  • 30-minute 1:1 review call
  • 7-day starter recommendations
Then, If It Fits

Constraint Map + Protocol + Retest

The natural continuation

If your map shows a clear constraint pattern worth training, GFM builds a focused protocol around it, checks in on execution, and remeasures cognitive performance at the end to assess what changed.

  • Everything in the Cognitive Constraint Map
  • Personalized protocol targeting upstream systems
  • Compliance check-ins
  • Retest battery
  • Before / after interpretation
  • Protocol adjustment recommendations

GFM works with a limited number of clients at a time. Both paths begin with a conversation, not a checkout.

The difference from generic wearable tracking: GFM pairs measured cognitive performance with your biometric context, then a human reviews the pattern with you. Not more data — interpretation.

The Criterion

Want to feel the kind of cognitive load GFM measures?

The Criterion is a short multiple-object tracking challenge. It is not the full assessment, but it gives you a quick feel for how GFM thinks about attention, tracking, persistence, and performance under load.

The full Cognitive Constraint Map uses a broader battery plus wearable/readiness context and operator review.

No wearable data yet?

You can still begin with a Map Review. For clients who continue into a 12-week protocol, GFM can include a supported wearable when consistent readiness and recovery tracking would improve the plan.

How it Works

Schedule. Measure. Map. Train + Retest.

01

Schedule

Start with a brief 1:1 to confirm fit and choose the right path.

02

Measure

Complete the cognitive battery and share wearable/readiness context where available.

03

Map

GFM reviews the data and identifies likely upstream constraint patterns.

04

Train + Retest

If you continue into protocol, GFM targets the upstream systems most likely affecting downstream cognitive output, then retests to show what changed.

GFM exists because most performance data never becomes a decision. Garrett built it to make cognitive performance measurable, interpretable, and trainable — with careful science and a human in the loop.

Good to Know

Questions & scope.

Who is this for?
Executives, founders, serious athletes, parents of serious youth athletes, and performance-minded adults who want interpretation rather than more raw data. Fit is confirmed on the first call — if GFM isn't the right tool for your situation, you'll hear that directly.
Do I need a wearable?
No. The cognitive battery stands on its own, and you can begin without any device data. If you have a wearable, its trend data adds useful context to the map.
Which wearables work?
Garmin, Oura, Whoop, Apple Watch, Fitbit, and similar trackers. You share trend data and complete a short intake; no live device sync is required.
What do I receive?
For the Cognitive Constraint Map, you receive a reviewed map, written summary, review call, and starter recommendations. For the Protocol, GFM adds a focused implementation plan, check-ins, and retesting.
Is this medical advice?
No. GFM does not provide medical diagnosis, treatment, or clinical advice. This is a performance-focused interpretation and coaching product.
What about youth athletes?
GFM works with parents, not directly with minors. Fit, appropriateness, and how the assessment would work for your athlete are discussed with you on the first call before anything is scheduled. Nothing here is diagnostic.
How do I start?
Schedule a Map Review. It starts with a brief 1:1 conversation to confirm fit, then the cognitive battery, then your reviewed map and recommendations — typically within days, not weeks.
