The readiness signal coaches have been missing.

InnerLoop AI turns an athlete's daily voice memo into a clear readiness signal, backed by reasoning coaches can actually trust.

The Problem

Coaches aren't short of data. They're short of meaning.

The last decade gave coaching every sensor imaginable. None of them answer the only question that matters at 6am: is this athlete ready to push today?

Data Overload
Wearables flood, signals become noise
Coaches drown in HRV, sleep stages, and load metrics — but raw numbers don't tell them what to do next.
Survey Fatigue
Forms that athletes stop filling out
Daily wellness questionnaires get gamed within a week. The data is clean — and meaningless.
The Missing Layer
What the athlete isn't saying
How an athlete actually feels — stress, hesitation, confidence — never makes it into the system. That's where injuries hide.
"We don't need more data. We need to know what the data means for tomorrow."
— National-team head coach, pilot interview
The Solution

One voice memo in. A trusted recommendation out — with the reasoning.

Three layers. Built for the way coaches actually decide.

  1. 01
    Frictionless input
    A daily voice memo from the athlete—no forms, no scales, no scoring. Just their own words.
  2. 02
    Neuro-symbolic processing
    A neural layer extracts acoustic biomarkers. A symbolic layer applies deterministic sports-science rules. Every output is explained.
  3. 03
    Actionable output
    A clear Green / Amber / Red readiness signal for the coach — with the reasoning, the dissonance, and the recommended adjustment.

Why it holds up

Built for accuracy, not just correlation.

The neural layer captures what athletes don't say. The symbolic layer applies the same rules a senior sports scientist would. Every output is auditable.

External Load
The work performed (distance, tonnage, speed).
Internal Response
The physiological & psychological cost.
Perceived Wellbeing
Recovery status (sleep, mood, soreness).
Readiness
Next-day capacity synthesized for the coach.
loop repeats

By automating Internal Response and Perceived Wellbeing, the AI closes the loop — so coaches can prescribe External Load accurately for the next day.
