Assay reads a prospect’s own website, scores the fit, and attaches to every field the exact sentence it was read from and the page that sentence is on.
A field it cannot quote ships marked unproven. Nothing is invented and nothing is quietly dropped.
Latest public run: 16 companies read for $0.80. 8 rejected. 27 of 110 fields thrown out because the quote was not on the page.
No customers yet. Nothing on this page is a customer result.

A scripted demonstration of the real mechanism. Not a customer result. Press replay to watch it check itself.
We are hiring two Sales Development Representatives to help us reach mid-market revenue teams in North America.
Outbound agencies resell data they cannot see inside. That costs them twice.
First, the bill. Per-credit tools charge for every enrichment, including the ones that fail, and the total moves 30 to 50 percent month to month with no line that explains why.
Second, the call. A client asks where a number came from. The only answer is a vendor’s name.
Credits that cannot be predicted, and claims that cannot be defended.
Reported jump: 4,000 to 6,000 US dollars in one month, with no change in client scope. Agency bills are reported to swing 30 to 50 percent month to month.
“Clay as a GTM orchestration tool is not worthwhile at any meaningful scale because of the actions costs. Simply running a handful of research prompts on say 5k people or companies and then syncing these to a sequencer costs hundreds of dollars, and that's when bringing your own API keys.”
“Tried Clay for prospecting and everything fell apart. Workflows froze, data was wrong, and credits vanished fast.”
“The credit model could be better; failed enrichments still burn credits, and we've blown through monthly credits early a couple of times.”
“If your SDR team expects to sign up and start prospecting on day one, Clay will frustrate them. It's a low-code data platform.”
Quoted from a September 2026 research pass over 30 cited sources. Sources are named in the file, not paraphrased here.
No tool in the sources shows the source sentence behind an enriched field, nor lets a user audit a claim back to the exact page sentence it was read from.
Ten tools were reviewed for the research. The sentence on the left is the finding, and the window it sits in is what a receipt looks like everywhere in the product: the words, then the page they came from.
| Question a client asks | Per-credit tools | Assay |
|---|---|---|
| Where did this come from? | A vendor name, or nothing | The sentence, and the page |
| Can I read it myself? | No | The url is on the row |
| What if the model guessed? | You find out from a bounce | The field ships marked unproven |
| What did this run cost? | Credits, worked out later | Dollars, while it runs |
| Can I take it in-house? | No, it is their platform | Yes, on the Own it plan |
No quote, no field.

Up to three public pages the company published for anyone to read. No broker list, no bought database, no scraped person. If no page can be read, the company gets no score at all.
For every field, the model has to copy a sentence out of those pages, character for character. A field with no sentence behind it comes back empty. Empty is allowed. Invented is not.
Each quote is searched for in the pages that were actually fetched. Curly quotes, dashes, spacing and case are folded first, so a real sentence is never failed on punctuation. Then it is on the page, or it is not.
It is not deleted and it is not quietly fixed. The field ships with a red mark that says the sentence was not found. A score with no verified quote behind it is pulled down to 40 and marked no.
A real sentence with a curly apostrophe. A real sentence split by a line break. A real sentence the page wrapped in bold.
An invented sentence. A real sentence with one word changed. Two real fragments joined that were never next to each other. A quote shortened with an ellipsis.
25 checks. A gate that has never failed is not known to work, so it is fed things it has to reject.
A deliberately mixed list: 8 companies that fit the profile and 8 that could not. Run on 9 September 2026.
Well-known companies were chosen on purpose. If a reader cannot open the page and confirm the sentence, a receipt is worth nothing.
Assay found the 8. It also rejected Salesforce, which does sell to revenue teams, because the profile asked for 20 to 300 staff and the page said otherwise.
A tool reporting 100% would be a tool that had stopped checking.

For comparison: independent 2026 testing put a finished lead on a per-credit tool between $0.50 and $3.00. The same 16 companies would be $8 to $48 there. This run was $0.80. Assay does not find contacts, and that is a real part of the difference.
Sending is domain warming, SPF, DKIM, inbox rotation and bounce handling. Get that wrong and a client's domain is burned, which does not undo. Keep Smartlead. Keep Instantly. Assay hands the row to them.
No personal emails, no direct dials, no scraped profiles. It reads what a company published about itself. A contact tool is still needed for contacts, and the price reflects that.
Reading three pages and thinking about them takes about 20 seconds a company. A database lookup takes under a second. Assay sells a checked answer, not a quick one.
No case study, no testimonial, no revenue. The only proof offered is a run that anyone can open and check, and it is linked above.
A six-person agency reading about 2,000 companies a month was costed at $1,895 to $5,325 a month on a per-credit tool in the same research. Assay’s plans are set against that number. The first 10 accounts get the Agency plan at $199, locked for 12 months.
The Agency plan, for the first ten accounts. The price holds for twelve months.

No. Clay finds people and orchestrates a hundred providers. Assay does one job: it reads a company's own site and proves what it says about it. Most agencies would run both, and use Assay for the research layer where the bill hurts.
It gets caught, visibly. The quote is searched for in the pages that were fetched. If it is not there, the field is marked unproven in the app and in the CSV, and if nothing on that company could be proven, the score is pulled down and the verdict is set to no.
Because the check is real. A model asked to quote will sometimes tidy a sentence, join two of them, or state something reasonable that the page never said. A tool reporting a perfect rate has either stopped checking or is checking something easy.
Reading a page a company published for the public, and quoting it with a link back, is what search engines have always done. Assay stores no personal contact data and builds no person-level profile, which is where most of the risk in this category sits. This is not legal advice.
Yes, on the Own it plan. It runs on your keys, in your stack, and the pipeline is handed over in Make or n8n so a person on your team can read it without reading code.
