Numbers as cleared by the owner. Nothing rounded, nothing added.
01
The situation
Data sold per licence is priced for the buyer who needs all of it. Most buyers need a slice, and pay for the licence anyway.
02
What was built
An extraction engine in Rust compiled to WebAssembly, run in pipelines that price the output per row.
On it: porownajweterynarza.pl, a vet marketplace with 4,650 clinics in 485 cities, and whitecontext-seo-pl, 2.55M .pl domains at $0.00033 per domain.
03
What changed
A buyer pays for the rows they take. The engine is owned, so the unit price is a number we set, not a licence we resell.
04
How it runs
Rust → Wasm pipelines, Cloudflare for the marketplace, on WhiteContext's own accounts.

You describe the situation; I ask three questions and propose a shape.
02
Savings audit
€1,200 / $1,400 net, 5 business days
The 36-month cost comparison, the order of moves, the risks and a fixed build price. Paid by bank transfer after the call, once you accept the offer; credited in full against a build ordered within 60 days of the report. If the audit does not show savings of at least twice its fee over 36 months, you get the fee back.
03
Build, handoff, operate
fixed price from the audit
One engineer builds every layer on your account and documents it. The offer includes a monthly plan by default, so the system is looked after from launch day.

Savings audit. In 5 business days: the 36-month cost comparison, the order of moves, the risks and a fixed build price in writing. It costs €1,200 / $1,400 net, paid by bank transfer against an invoice after the call and after you accept the offer. If you order the build within 60 days of the report, the full amount comes off its first instalment; if not, the report is yours to take to anyone. If the audit does not show savings of at least twice its fee over 36 months, you get the fee back.
The repository, the Cloudflare account, the domains and the data sit under your company from day one, and the data is yours. Code built only for you becomes yours once it is paid for, as the contract sets out; H2M modules come with a perpetual licence. I get access to your accounts, not ownership of them.
The audit gives you a date and a fixed price before you commit to the build. The stack is small and one person builds every layer, so nothing waits in a queue between departments.
Yes, before you send the brief if you need it. Send yours or use mine.
