Silicon Valhalla Methodology
This page explains how Silicon Valhalla sources, organizes, and updates Nordic startup and tech company profiles. The goal is a directory that is transparent enough for researchers and useful enough for everyday market discovery.
Geography
Norway, Sweden, Denmark, Finland, and Iceland
Output
Company profiles, taxonomy pages, and jobs data
Inclusion criteria
Companies are included when they are clearly part of the Nordic technology ecosystem and have enough public information to support a structured profile. The directory is intended to cover startups, scaleups, and notable technology companies that matter for ecosystem mapping.
Source inputs
Source inputs include curated company records, public company websites, public market references, and structured enrichment fields such as location, industry, tags, employee range, founding year, profile metadata, and manually reviewed jobs scraped from public careers pages.
Normalization rules
Company data is normalized into consistent country, city, and industry taxonomies so landing pages can aggregate cleanly. Duplicate companies are merged by name, whitespace and aliases are normalized, and page slugs are generated from canonicalized names rather than raw source strings.
Update cadence
The directory is updated in batches as new companies are added and profiles are refined. Freshness is surfaced publicly on key pages so visitors can see when the current snapshot was last refreshed. Jobs are refreshed from the checked-in scrape dataset and linked back to the employer careers page so visitors can verify every role against the source.
Content policy
Landing page summaries are written to support discovery, not to masquerade as exhaustive analyst reports. The copy is intended to explain ecosystem patterns, highlight concentrations by country or industry, and guide visitors toward the most relevant company pages.
