Managed scraping + QA · vendor replacement

Your vendor delivers data. We show you what's missing.

We run one of your vendor's scrapes ourselves, compare it head-to-head, and hand you the gaps — what's missing, why, and the evidence. Yours to keep and verify. Free.

Step 01
Audit

We run your vendor's scrape independently and compare it head-to-head. The gaps in coverage, accuracy, and cost surface.

Step 02
Acquire

Where we take over, we run our own scrapers. No reselling another vendor's infrastructure.

Step 03
Certify

Dual-layer QA: dropped-record check plus LLM-assisted sampling on the records most likely to be wrong.

Step 04
Deliver

Data plus a plain-language report explaining every meaningful change since last delivery.

Diagnostic

Missing data is silent.

Spot-checks catch errors in what your vendor delivers. They can't catch what isn't there. Samples are blind to absences by design. Only an independent comparison surfaces them.

Standard sample coverage 0.005%
Q1

How do you know your vendor's deliveries are 100% accurate?

Q2

How do you know what they didn't get?

Q3

If they can't scrape a site, could someone else unlock that revenue?

Q4

Could someone do this cheaper, with modern approaches, and catch more than your current vendor?

The Gap Audit answers all four — and hands you the proof. →

Method

How the Gap Audit works. Inspect it.

No black box. Here's the exact procedure, so you can judge the test before you send us anything — and re-check our numbers against your own delivery after.

Step 01Independent re-run

We scrape the same source ourselves, from scratch

We don't touch your vendor's pipeline or trust their output. We take your URL list and instructions and run our own independent scrape of the live source — same scope, same target. Two independent pulls of the same ground truth.

Step 02Head-to-head comparison

We diff our pull against your vendor's last delivery

Record by record, field by field. Records present in one and absent in the other. Fields populated in one and empty in the other. Values that disagree. The audit can't run without your vendor's full last delivery — there's nothing to compare against otherwise.

Step 03Dual-layer QA

Dropped-record check + LLM-assisted targeted sampling

Layer one: a dropped-record check confirms every record that should exist at the source is accounted for in the comparison. This is what catches silent absences.

Layer two: LLM-assisted sampling concentrates human review on the records statistically most likely to be wrong, instead of a blind 0.005% sample. We tell you exactly which records were checked, and how.

Step 04Like-for-like discipline

A fair test, not a stacked one

We compare in-scope against in-scope only. A vendor returning out-of-state records on a state directory isn't "more data" — it's the wrong data, and we don't count it in our favour. De-duplicated, scope-matched, same time window. If the gap shrinks to zero under fair comparison, the report says so.

Evidence

We audited the data they trusted. Here's what was missing.

Where it goes from here

Start with the audit. Go as far as the proof earns.

The audit is free and yours to keep — that's how we prove ourselves. Everything after is optional and at your pace. If the proof holds up, the path ends with us replacing your vendor entirely.

01

The Gap Audit

We run one of your vendor's scrapes independently and hand you the findings — what's missing, why, and the evidence. Yours to keep and verify.

Free
02

The walkthrough

A 30-minute live review of the findings: what's missing, why it matters, and what it's worth fixing. No obligation to go further.

Free
03

Fix the gaps

Where you want it closed, we re-engineer the broken scrapes and re-run the audit so the gap can't reopen silently.

Optional
04

We take over the scraping

When it makes sense, we replace your vendor entirely — our own infrastructure, the dual-layer QA bundled in, priced as a swap, not another line item.

Optional
The artifact

See exactly what you'd get.

Not a teaser. The Gap Audit report is the deliverable — and it's yours to keep. Below is a redacted sample from a real engagement: the gap, the cause, the evidence trail, and the per-source breakdown you can verify against your own delivery.

What we'll need to run it Your vendor's full last delivery. We compare against it head-to-head, so the audit can't run without it. You start with a sample and send the rest once we begin.
What you keep The PDF Gap Audit Report + evidence trail · yours to keep and re-verify, with a 30-min live walkthrough of the findings. No obligation to engage us.
What's the engagement Taking over the scraping, fixing what's missing, and the ongoing bundled QA — the managed service the audit opens.
Timeline 10 business days from handoff.
Sample-first You start with 5–20 rows. We never ask for the full dataset before you've decided to proceed.
Data handling Your data is used only to run your audit, never resold or shared. Deleted on request. See our privacy policy.
No lock-in The report is yours whether or not you ever work with us. The findings don't expire.

FAQ

"What's free, and what do I pay for?"

The audit and its findings are free and yours to keep — what's missing, why, and the evidence. Verify it and walk away if you like. The paid part is the managed service: we take over the scraping, fix what's missing, and ship the bundled QA on every delivery going forward.

"What if your numbers are wrong?"

You'll catch it, because every figure is traceable to row-level evidence you can re-check at the source. The dropped-record check catches what spot-checks miss, and the report tells you why in plain language.

"We don't have budget for another tool."

You don't need new budget. The audit is free, and the managed service replaces your current vendor's line item — we price comparable and bundle the QA at no premium. A swap, not an addition.

"How does the audit wrap up?"

We send the report and walk you through it: what's missing, why, and what it's worth fixing. The 30-minute walkthrough is where the value lands. The report stands on its own whether you proceed or not.

Next step

We'll prove it on your real data. Then you decide.

Free. Ten business days. We run one of your vendor's scrapes, hand you the findings to verify yourself, and walk you through them. Worst case: you learn your current setup is fine — and you keep the report anyway.
