what it is
A pipeline that finds Finnish companies with an old, live site and money, reads the site, has a model rebuild it as a one-page site, and shows the owner the old beside the new. The offer goes by email and by a letter in the post. Payment and hosting are the shop, kauppa.
what it does
- Imports companies from the PRH open data register and Tax Administration data; the pool is about 1,500 companies at a time.
- Reads a company's site page by page through Lukija, and the registers through Clients and Tutka, into one digest with sources.
- Drafts the new site through the Claude Agent SDK, keeps the manifest, writes the letter.
- Persistence on EF Core and SQLite, aggregates as entity configurations, every job logged.
