Not just AI labs — any business can post.

Whether you're a model team that needs ground-truth data or a solo owner who needs simple tasks done, you post the work and a verified, qualified human workforce completes it.

AI teams

Ground-truth data

RLHF, evaluation, labeling, moderation, translation QA — done by identity-verified humans with a proof-of-work trail on every unit.

Small & solo owners

Get simple tasks done

Need information gathered, data entered, listings checked, content reviewed, or a simple task handled? Post it to the task board at client pricing — only members who qualify for that task can pick it up. No team to hire, no overhead.

Why our labels don't drift.

Three structural reasons 5arz quality outperforms the cheap end of the market — and matches the expensive end at a fraction of the cost.

⏱

Dwell-time anti-fraud

Every task category has a minimum read time enforced before the submit button activates — 4 seconds for content mod, up to 15 seconds for document understanding. Click-spammers get filtered at the source.

Tier 1 · Live
★

Goal-driven retention

Our workforce isn't gigging for pennies — they're earning real money toward real goals. They stick around, they care, and quality compounds. Structurally higher retention than any anonymous gig-pool vendor.

Structural moat
⌬

Optional biometric proof

For enterprise pipelines, every task can be cryptographically signed by a verified human via TEE-attested biometric proof. Patent-pending — USPTO Provisional 63/979,474.

▍ Pre-collected datasets

Buy a verified dataset — every label carries proof-of-work.

Don't want to post tasks? Buy a pre-collected dataset of completed, verified-human task output. Every row ships with: completing-member id (hashed), task category, completion timestamp, verification status, and an audit trail tying back to an identity-verified Star earner. UCC Article 12 "take-free" framing in the buyer agreement (counsel-reviewed).

Why this is different: Most "human-labeled" datasets on the market today were labeled before bot-poisoning became cheap. Ours are bot-resistant by construction — every Star earner is identity-verified (Stripe Identity), server-checked per-task (anti-fraud scoring), and (roadmap) cryptographically signed via TEE-attested biometric proof. Provenance + chain-of-title in writing. Patent-pending USPTO Provisional 63/979,474.

Questions buyers ask first.

If yours isn't here, the signup form has a free-text field, or email info@5arz.com.

How do you guarantee quality at $0.35/task?

Three things: (1) verified, identity-bound workers — not anonymous crowds. (2) Dwell-time gates and acceptance scoring on every submission. (3) Workers stay sticky because they're earning real money toward real goals, not gigging for spare cash. Quality acceptance averages 96%.

Are your workers actually qualified?

Every member completes Stripe Identity verification, real-debt verification, and category-specific onboarding. Specialty categories (medical, legal) gate on credential checks. You see worker capability tags before assignment.

What about data security?

All task data is encrypted in transit (TLS 1.3) and at rest (Cloudflare D1 + R2 with AES-256). PII is stripped from worker surfaces unless you explicitly opt in. SOC 2 Type 1 audit in progress. Full security policies available on request.

Can I sign a DPA and NDA?

Yes. DPA is GDPR + CCPA aligned with Standard Contractual Clauses for EU. Mutual NDA is included by default at Scale tier and above. Both signed in-app and stored on your business profile for re-download.

How does pricing actually work?

Self-Serve is pay-as-you-go at $0.50/task with no minimum. Scale is $0.35/task billed monthly with 10K-task minimum. Enterprise is custom prepay blocks with volume discounts to $0.18/task at >1M tasks/year.

What if a task batch fails QA?

You're not billed for tasks below your acceptance threshold (default 90%; configurable per batch). We re-route failed tasks to a senior reviewer pool at no extra cost on Scale+ tier. Acceptance reports ship with every delivery.

Can I run a free pilot?

Yes. First 500 tasks free for AI labs and research groups, no commitment, no credit card. Drop a note in the signup form's "use case" field — we onboard pilots within 24 hours.

How is this different from Scale AI?

Two structural differences. (1) Price — we're 60–75% cheaper on equivalent task quality. (2) Provenance — every contributor is identity-verified and every unit ships with an auditable proof-of-work trail, so you can prove a real human did the work (no bot contamination). Plus you self-serve in 5 minutes vs. a 4-week sales cycle.

Ready to redirect that vendor spend back to engineering?

Most teams ship their first task batch within 4 hours of signup. The pilot is free for AI labs — drop a use-case note when you sign up.
