# TOP

> TOP (TOP Performance, Inc., use.top) checks each pro athlete's bedroom at home every night and tells the team's performance staff what to fix, and how. A plug-in sensor by the bed measures heat, humidity, stale air (CO2), dust (fine particles), light and noise. It has its own cellular connection, so it needs no wifi, and players have nothing to wear or charge.

TOP is for performance staff at professional sports clubs: Directors of Performance, sports science and medical staff. Half of elite athletes sleep poorly, and lost sleep cuts performance by 7.6%. Players usually think their bedroom is fine. TOP measures the room so staff can fix it.

How it works:

1. A sensor by each bed. Each player takes one home and plugs it in. It is live in minutes on its own cellular connection.
2. TOP finds what to fix, every night, in every bedroom: for example too warm, stale air or too humid.
3. Staff fix it the same day. They buy what the bedroom needs (a fan, a dehumidifier) or send the fix to the player's phone (for example: open the window for 15 minutes before bed).
4. TOP checks that it worked. It compares the seven nights before each fix with the seven nights after, then keeps checking.

Results and customers:

- In one customer's first week, TOP found something to fix in 7 of 10 bedrooms.
- Across TOP's customers, the average Bedroom Score was 25% better after 11 weeks than in the first week.
- LAFC (Major League Soccer) uses TOP. Gavin Benjafield, Performance Director at LAFC: "For years we've measured the athlete, but never the room they sleep in. TOP is the first company I've seen that does."

The research behind it:

- Half of elite athletes sleep poorly (Swinbourne et al., European Journal of Sport Science, 2016; 175 elite team-sport athletes).
- Lost sleep cuts performance by 7.6%, and sport-skill accuracy by 21% (Craven et al., Sports Medicine, 2022; meta-analysis of 69 studies).
- Injury risk was 2.25 times higher when training went up and sleep went down (von Rosen et al., 2017; 496 elite athletes aged 15 to 19, 52 weeks).
- People who were awake for more than 8% of their time in bed were 5.5 times as likely to catch a cold (Cohen et al., Archives of Internal Medicine, 2009; 153 adults).
- 92% of people said their bedroom air was good, but 83% of the bedrooms measured were stale overnight (Sharpe et al., 2015; 200 people surveyed, 40 bedrooms measured).

AI Coach: TOP's AI Coach does the follow-up work for the performance staff. It watches every bedroom around the clock, opens an issue when a problem keeps coming back, sends the player one short fix through the TOP app before bed (at most one message an evening), and measures the nights after the fix against the nights before. Each issue ends as better, no change or worse since the fix. Staff watch it on a live Issues board and can take over any issue. The AI Coach is part of the TOP suite, not an add-on, and costs nothing extra.

Privacy: TOP measures the room, never the person. There is no camera and nothing is recorded. Light is one number and sound is a decibel level; audio is never stored or sent. Each team sees only its own bedrooms. Only the team's staff and the player see the data.

Athlete app: each fix reaches the athlete's phone, sent by the AI Coach or written by staff from the dashboard. In the TOP app (iOS and Android), the fix sits next to live readings from the player's own bedroom, updated every minute, and a summary of what got in the way of last night's sleep. A player opens it by scanning the code on the sensor; there are no accounts.

Price: teams start with a 30-day pilot for $500. It includes 4 sensors and the full TOP suite, including the AI Coach. TOP follows up in the first week with what it found in the team's bedrooms. After the pilot, TOP and the team plan the roll-out for the whole team together. TOP does not charge per sensor.

Coverage: the sensor connects on its own cellular connection in 167 countries and territories.

Company: TOP Performance, Inc., 250 Broadway, New York, NY 10007, USA.
