Effloow
Proof Studio · executed verification

Your tool's claims,
actually executed.
Proof you can sell with.

For AI tool vendors who need more than a review. We run your product in a controlled sandbox, record what works and what fails, and hand you proof assets: a reproducible repo, run logs, failure notes, and a claim table your sales team can quote.
→ Best for AI dev tools, agents, APIs, and infrastructure preparing a launch, a sales push, or an investor update
→ Not guaranteed praise — findings are findings, and failed runs stay in the record
→ Founding offer 3 sprint slots at $1,000 with case-study rights, then $1,500 standard

What a sprint delivers

ASSETS, NOT JUST AN ARTICLE
Included

Reproducible repo

The exact harness, fixtures, and commands we ran — your team or your buyers can re-run it.

  • Public or private repo
  • Pinned dependency versions
  • Setup instructions
  • Run scripts
Included

Run record

Append-only evidence: every run, every model ID, every failure, hashed into a tamper-evident manifest.

  • Run logs with request IDs
  • Failure and retry notes
  • Token/cost summary
  • SHA-256 manifest
Included

Sales-ready claim table

Each marketing claim mapped to the run that supports it — or the honest limitation where it fell short.

  • Claim-to-evidence mapping
  • Safe wording your team can quote
  • Known limitations stated
  • Comparison notes where scoped
Optional

Public verified report

A disclosed, sponsored report on effloow.com that buyers and investors can link to.

  • Sponsorship disclosed
  • Method fully published
  • Findings not editable
  • You choose whether to publish

Why this is different

PROOF VS PROMOTION
Sponsored review
Proof Studio sprint
Execution
Often docs-based
Sandbox-executed, every run recorded
Model claims
Loosely implied
Claim-bound: a result only covers the exact model and setup it ran on
Failures
Edited out
Kept in the record — failure notes are part of the deliverable
Method
Hidden
Published: model IDs, versions, commands, environment, cost
Vendor input
Controls the copy
Private preflight to fix setup mistakes — findings are never edited

How a sprint runs

5 DAYS · ASYNC
01

Scope the claim

You send the claim buyers doubt. We reply with the test plan, the exact model/stack it will run on, and the access we need.

before payment
02

Grant sandbox access

A temporary, least-privilege key or sandbox account with a spend cap and a revocation deadline. We never need production access.

your control
03

Execute and record

We run the test plan. Every run lands in an append-only evidence record — successes, failures, retries, and costs.

days 2–4
04

Preflight, then deliver

You get a private preflight to catch setup mistakes — not to edit findings. Then the repo, run record, and claim table are delivered, and your sandbox access is revoked and restored.

Answered

THE QUESTIONS VENDORS ASK
Is this just sponsored content?

The engagement is paid and always disclosed. What you are buying is execution and evidence, not a verdict. Findings come from recorded runs, and you cannot edit them — that is exactly what makes the result quotable.

What happens if our tool fails the test?

Failed runs stay in the evidence record. You get a private preflight to fix setup mistakes before the real runs, and you decide whether the public report is published — but a published report always includes limitations.

Which models do you run on?

Whatever the claim names. A claim about your agent on a specific model is executed on exactly that model — we never substitute a cheaper model and imply the result transfers.

What access do you need?

A temporary, least-privilege API key or sandbox account with a spend cap you set and a revocation deadline. After delivery we confirm nothing billable is left running.

Can you also write the launch article?

Yes — content is a separate, existing service line. A sprint can feed a lab-backed article, a tutorial, or launch copy. See our content services page.

One claim.
Executed, recorded, quotable.

Send the claim your buyers doubt most. We'll reply with the test plan and what it takes to prove it.
