Does that certificateresumeexamreferencecredentialbadgecertificate
prove they can do the job?

No. So we built what does. ProofPath verifies capability
from the work itself ~ proof that AI can't fake and time can't erase.

The state of the art

Every workforce decision today
is made on a proxy.

A test score. A certificate. A manager's word. Years on a résumé. Guesses dressed up as credentials.

01

They don't compare.

One context calls it a passing test. Another calls it a certification. A third calls it a manager's nod. Same word, different evidence, no common floor.

02

They decay invisibly.

A credential earned in 2023 looks identical to one earned last week. Capability fades; the line on the résumé doesn't.

03

They can't be audited.

No way to point at the evidence behind the claim. No replay. No math. Trust me ~ and hope you never have to prove it.

Capability isn't a checkbox.
It's a question you have to answer today ~ with confidence, grounded in evidence.

The platform

Computable human capability.

ProofPath mathematically proves what a person knows and can do ~ from a single fact to an entire job ~ at any point in time.

Knowledge graph

Your domain decomposed into facts, dependencies, and competencies. Federated, mutable, surgically updatable. No rip and replace.

Four evidence channels

Video task execution, adaptive interview, adaptive exam, and ambient work signals ~ all flowing into one inference core.

Decay per skill

Every competency has its own learned half life. The system knows when each specific skill is fading for each specific person.

Immutable evidence ledger

Every claim traces to the evidence behind it. Fully auditable. Fully replayable. The source one click away.

Evidence

One picture. Four signals. No proxies.

Most platforms verify a slice of the truth and call it the answer. ProofPath fuses four asynchronous channels into one live probability that this person can do this thing today.

01

Watch the work itself.

Video assessment

Observed task execution with automated procedural scoring. The capability our category has never shipped.

02

Probe the reasoning.

Adaptive interview

Socratic AI questioning with live contradiction detection against the knowledge graph. Powered by Bayesian Knowledge Tracing.

03

The psychometric gold standard.

Adaptive exam

Item Response Theory ~ calibrated, defensible, the anchor across channels that makes the rest of the signal trustworthy.

04

Use what you already have.

External evidence

Certifications, work logs, outside assessments, ambient telemetry. Stealth assessment from work already being done.

Every channel writes to the same immutable ledger. Every score traces back to the clip, the transcript, the work order that produced it.

Why this is different

Not built on AI.
Built on math that consumes it.

Most competency products built around AI wrap an LLM ~ thin product, thick model. They commoditize as models commoditize. ProofPath is the opposite shape: a deterministic inference core grounded in published research, with frontier models plugged in as replaceable tools.

01

One rule, five problems

Mastery, calibration, routing, decay, and self verification ~ five separate problems in the literature, each treated independently. They collapse to a single Bayesian update.

02

Deterministic, not a black box

Every score is explainable down to the contributing evidence, reproducible on every replay, and defensible in audit. The kind of math an enterprise compliance team can sign off on.

03

The physics of forgetting

Adaptive half life regression ~ pioneered by Duolingo, validated across billions of traces ~ adapted for professional competency. Each skill has its own learned decay.

Built for

Wherever capability has to be more than a checkbox.

Hiring is just the most legible example. The same question ~ is this person capable, right now, with what confidence, grounded in what evidence ~ has to be answered in credentialing, workforce planning, compliance, and licensure renewal.

Enterprises

Workforce verification & compliance

Continuously verified competency dashboards across your workforce. L&D reports that are defensible, not aspirational. Compliance breaches surfaced before they happen.

  • Tenant isolation
  • Enterprise SSO
  • Evidence trail you can audit

Education platforms

Credentials that stay current

Turn a single credential into a living, continuously verified claim. Reassessments triggered by decay become recurring engagement ~ not an annual exam.

  • Agnostic to content format
  • No catalog migration
  • Recurring revenue surface

Hiring

Capability today, not a stale credential

Ask "can this person actually do this, right now?" ~ and get a statistically backed answer with the evidence behind it. One click from score to the clip.

  • Confidence intervals per skill
  • Comparable across contexts
  • Living candidate profiles
Integration

A headless intelligence layer. Yours to wire in.

Format agnostic and vendor agnostic by design. PDFs, SCORM, video, SOPs, outside assessments, work logs ~ feed any of it in and leave the raw content where it lives.

Public REST API

Read and write capability state from your existing stack. Generated SDKs, typed endpoints, full observability included.

MCP server

Expose your competency ontology to Claude, ChatGPT, and any model that speaks MCP. Ask "who is the best fit for this work order?" in plain language.

Event ledger

Stream every capability signal to your data warehouse. Append only, replayable, financial grade ~ the same ledger we score from.

Tenant isolation · Enterprise SSO · Full observability · No catalog migration required

Private beta · Select enterprise partners

A live capability score for every person and every skill.

With the evidence behind every claim, the decay curve behind every projection, and the math behind every score ~ one click away.

Proof Path

Turn subjective trust into objective validation. Capability you can measure, at any scale.
