The Peak Hours™ Company Most executives run on 1.5 peak hours.
You were built for six.

Peak Hours™ is the number of hours a day your brain truly operates at its peak — before fatigue and stress quietly take the rest. We measure it, then we rebuild it.

Brain

The command layer. We measure focus, working memory and mental speed — then rebuild the hours where your thinking is genuinely sharp.

The Number

One number for the
day you actually have

Not steps. Not sleep score. Peak Hours™ — the hours per day your brain runs at genuine peak capacity. Everything we build serves that single, honest number.

Most high performers assume they have a full day of sharp thinking. Measured objectively, the reality is closer to ninety minutes. The other hours still happen — they're just quietly sub-peak. B4lounge finds your real number, then extends it.

Questions

The essentials

A Peak Hour is an hour in which your brain operates at genuine peak capacity — fast, focused and clear — before fatigue and stress degrade it. Peak Hours™ is our single measure of how many of those you get in a day, and it's the number every part of B4lounge is built to improve.

No. The Brainground games and the B⁴ Scan are open and free. They give you an instant, illustrative Peak Hours™ indicator. Private programmes in the Peak Circle are separate and begin with a Discovery Call.

Your Scan result blends the four dimensions — Brain, Body, Beauty and Boost — at equal weighting, normalised onto the Peak Hours™ scale, then mapped to your R.E.O.B. stage. In the private programmes, self-report is replaced by lab diagnostics such as qEEG, HRV and biomarker panels.

Founders, executives, clinicians and athletes — anyone whose output depends on the quality of their thinking, and who would rather measure it than guess. The programmes are private, discreet and led personally by Dr. KAF.

No. The open games and Scan are for orientation and are illustrative. Clinical assessment and any medical decisions happen inside a programme, with Dr. KAF, using validated laboratory diagnostics.
