THE PROBLEM

Four resources. Four silos. Zero connection.

Time lives in your calendar. Money in your bank. Energy in your body. Knowledge in your head. These four resources convert into each other every day — but the tools you use to manage them have never exchanged a single data point.

YOUR ξTM

This is what your real rate looks like

ξTM is your effective hourly rate — what an hour of your time actually produces, not what your contract says. It updates daily based on your energy and expertise.

THE MATH

One equation. Backed by research.

Every multiplier in Arbipower is derived from published meta-analyses — not vibes, not guesswork. Your effective rate is your base rate, scaled by two validated factors.

ξTM = Base × fₑ(E) × gₖ(K)

BASE RATE

Your contractual hourly rate

The number on your contract or invoice — before any adjustment.

fₑ(E) — ENERGY

How your body scales output

Sleep, physical state, nutrition, psychological wellbeing. Ranges from ×0.30 (burned out) to ×1.00 (full capacity).

gₖ(K) — KNOWLEDGE

How expertise scales output

Domain-specific skill level. Ranges from ×0.83 (beginner) to ×1.11 (expert). Per-domain — your Python rate differs from your Marketing rate.

HOW IT WORKS

Three inputs. One number that matters.

Set your base rate once. Check in daily with four sliders. Arbipower does the rest.

01

Set your base rate

Your contractual or market hourly rate. Set once, adjust anytime.

$10 to $10,000 — freelancer to executive.

02

Check in daily

Four sliders: sleep, physical, nutrition, psychological. Takes 15 seconds.

Works offline. Syncs when reconnected.

03

See your real rate

Your ξTM updates instantly. See the hidden cost — or gain — versus your base.

Track trends over 7, 14, 30, or 90 days.

VALIDATED DEMAND

Built from real pain points

Before writing code, we surveyed knowledge workers about resource management. The pain is structural, not personal.

Average pain score for lacking decision clarity across resources

76.5%

Have turned down good money due to energy or time constraints

65%

Don't realize their tools are structurally disconnected

Survey: n=17 knowledge workers, Q4 2024
