Data platforms that pay per row, not per seat

A Rust-to-WebAssembly extraction engine behind a vet marketplace and an SEO dataset: 2.55M .pl domains priced at $0.00033 each.

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.

How the pieces connect

The system on one map. Arrows show what feeds what; hover a piece to light its path.

If you want one of these

Three steps. The six-step version, with the brief and the video request, is on the home page.

  1. 01

    Scoping call

    30 min, free

    You describe the situation; I ask three questions and propose a shape.

  2. 02

    Roadmap and architecture

    $1,250 deposit

    A written plan with a date. The deposit is credited to the first invoice; the documents are yours either way.

  3. 03

    Build, handoff, operate

    date on the roadmap

    One engineer builds every layer on your account, documents it, and can keep operating it.

Questions I get about this

Tap a question. The answer comes back like a text.

Scoping calls · most weeks

A written roadmap and an architecture for your system, delivered after the scoping call. If we build together, the full amount comes off the first invoice. If not, the documents are yours to take to anyone.

You do. The repository, the Cloudflare account, the domains and the data sit under your company from day one. I get access, not ownership.

The roadmap gives you a date 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.

Something else? Ask it on the call

A 30-minute call, free

Thirty minutes, then a written plan

Leave an email. I reply within one working day with three questions and a proposed plan, not a deck.
