Neuroperformance · Measured

Most executives run on 1.5 peak hours. You were built for six.

Peak Hours™ is the number of hours a day your brain operates at genuine peak — before fatigue, stress and circadian drift erode it. We measure yours. Then we close the gap.

We don't guess how your brain performs. We measure it.

The world's first integrated neuroperformance scan — built by a neurosurgeon. Brain and energy first; the rest follows.

Brainground · Open to all

Come in. Play.
Discover your capacity.

The Brainground is our open playground for the mind. Anyone can step in and play a short, scientifically-grounded game — and walk away with a real indicator of cognitive capacity and Peak Hours™. No appointment, no commitment.

Every game you play is a partial signal. Complete the full B⁴ Scan and your Brainground results carry over and count toward your Peak Hours™ assessment — the play becomes the proof.

The B⁴ Neuroperformance Scan

52 questions. One number.

A 10-minute self-rating across four dimensions — Brain, Beauty, Body, Boost — producing your Peak Hours™ score and R.E.O.B. stage. Below is the complete questionnaire as a guest would see it.

Start page
Background — collected at the end
BOOST ≥ 4.2Peak zone — sustain & extend Peakspan
OPTIMIZE 3.5–4.1Strong base — targeted protocols
ENERGIZE 2.8–3.4Sub-peak — rebuild systems
RESET < 2.8Focused intervention — Reset Day + lab
Demo note: Peak Hours™ here is computed live from your selections (equal 25% dimension weighting, normalised to 5.0) for illustration. Production scoring applies reverse-item handling, validated-instrument mapping (PHQ-9, MSK-HQ, SMBM, etc.) and clinical screening flags per the technical spec.
Private Programmes

The Peak Circle.

Two neuroperformance partnerships built around the personal attention of Dr. Finjap — one for principals over the long arc, one for athletes ahead of the season that matters.

B4lounge Private · Invitation only
Peak Circle · Executive
from €60,000 / 18-month programme
Single principal · limited cohort each year
  • Direct line to Dr. Finjap. Exclusive personal oversight of your protocol for the full 18 months — she designs it, she reviews it, she adjusts it.
  • Quarterly Executive Lab Days. Six full diagnostic days across all nine clinical technologies (qEEG, HRV, EXOMIND, Styku, biomarker panels, FMS & more).
  • Continuous Peak Hours™ tracking. Wearable-integrated monitoring between visits, reviewed each quarter.
  • Unlimited Brainground+. Full neurotest battery on demand, with longitudinal trend reporting.
  • Personalised R.E.O.B. roadmap. Restore → Energize → Optimize → Boost, sequenced to your calendar and travel.
  • Concierge & priority access. Booking around your diary, and priority access to the flagship hub and partner lounges.
  • Annual Peak Hours™ dossier. A confidential year-end report benchmarking your trajectory.

The 18-month arc

Three six-month phases — measured, intervened, and extended.

Months 1–6 · Restore & Map

Establish the baseline

Full B⁴ scan, Brainground battery and a complete lab work-up. Dr. Finjap personally interprets the data and sets your protocol. We remove the biggest drag on your Peak Hours™ first.

Months 7–12 · Energize & Optimize

Build the system

Targeted interventions across brain, energy, structure and recovery. Quarterly lab days track objective movement. Protocol adjusts to your real-world travel and workload.

Months 13–18 · Boost & Sustain

Extend the Peakspan

Lock in gains and push toward your ceiling — more peak hours, held longer. Year-end dossier and a forward plan for the next cycle.

Demo note: both programmes — the €60,000 / 18-month Executive and the €15,000 / 3-month Athlete — are proposed designs for review, not published offers. Final inclusions, cadence and pricing to be confirmed by B4lounge.

Founder · Chief Medical Officer & Scientific Lead
"Neurosurgical precision meets personalised neuroperformance medicine."

Dr. Finjap is a board-certified neurosurgeon and habilitated academic who built B4lounge on a simple conviction: sustainable high performance starts in the brain, and what can be measured can be improved. She is the architect of the B⁴ Alignment Model, the N·E·U·R·O-C.A.M.P. framework and the Peak Hours™ metric.

She studied medicine at Ruprecht-Karls-Universität Heidelberg, completed her basic surgical training at University Medicine Mannheim, and specialised in neurosurgery at Ruhr University Bochum, where she earned her Habilitation. Her path runs through orthopaedic practice in Cologne, clinical research at the DKFZ German Cancer Research Center, and the pharmaceutical industry — before founding her own Privatpraxis-Institut in Neustadt an der Weinstraße under the concept Kinetic Aesthetic Fusion and the credo "Confidence in Motion."

That dual fluency — neurosurgical and aesthetic, clinical and entrepreneurial — is the difference B4lounge is built on. Where performance coaching estimates, she measures; where wellness soothes, she objectifies.
