The full core loop — enroll, prove, verify, earn your Outcome ✓ — costs nothing. No trial. No paywall. Ever.

Real proof, not recall

Every milestone requires a real artifact — built, shipped, performed, recorded. We apply an AI-Fakeability Test: if an AI can produce your proof without actually doing the work, it doesn't count.

No MOOC-style quiz certificate

Unlike Coursera or edX, nothing here comes from passing a multiple-choice test. An AI could ace those. Here, proof is what you built, made, or performed — not what you knew on a Thursday afternoon.

Verified by real, named people

Never self-certified. Never scored by an algorithm. A named peer who knows the domain confirms your proof is real — and puts their name to it.

The difference between claiming and proving.

Claiming

"I know Python" (LinkedIn skill endorsement)

"I'm a leader" (resume bullet)

"I ran a marathon" (Strava activity)

"I'm fluent in French" (Duolingo streak)

Proving on Powstik

Built a RAG system deployed at [URL] with 1,200 users — 3-min demo recording, peer-verified by 2 engineers

Delivered a project through my team without writing a line of code — team member endorsed this proof directly

Finished marathon in 4:12:33 — GPS data, finisher cert, 300-word reflection submitted within 48 hours

5-min recorded conversation with a native French speaker — tutor name and profile linked

Anyone can claim. Only Powstik makes you prove.

ONLY ON POWSTIK

Proof for the parts of a life an LMS was never built to see.

Governance

Leadership without a title

Leadership proven through retention and voluntary engagement — not an org-chart label. No MOOC has a proof standard for this.

“Led a 200-person community — 80% retention over 6 months, attested by 4 members I led.”

Only on Powstik

Longevity

What your body actually did

Health proven by measured outcomes — resting HR, lab markers, finish times. Clinical proofs stay private by default. No app streak can fake this.

“Dropped resting HR from 72 to 54 over 9 months — wearable export + bloodwork attached.”

Only on Powstik

Sport

Timed, tracked, undeniable

Performance proven by chip times and GPS — not a participation badge. The proof is the result. Every marathon, every PR, immutably yours.

“Berlin Marathon in 3:48:11 — official chip time + full GPS export submitted.”

100 paths across 8 domains

Every kind of proof. One platform.

Structured paths, free resources, peer-verified milestones — for adults, students, and K12 students.
