Firmalisten by Tekki

Firmalisten is our in-house platform built to monetize public company data from Norway's Brønnøysundregistrene.

It provides structured, enriched company profiles—including ownership, financials, emails, phone numbers, and more—searchable through a fast, intuitive interface. Users can generate contact lists and export them in Excel or JSON with custom field selections.

The business value lies in its simplicity and power. Marketing professionals, analysts, and business owners use Firmalisten to find leads, research competitors, and identify opportunities. Unlike other tools, it supports "empty searches", enabling broad discovery without knowing a company name or org number up front.

Under the hood, it's powered by NodeJS, Golang, Meilisearch, MongoDB, and Redis. Stripe handles payments, while custom caching and indexing deliver sub-second response times. Firmalisten runs lean, generates recurring revenue, and is built for low-maintenance, high-reliability performance.
