Top B2B Companies in Norway

TrustList ranks 88 companies in Norway across 4 categories. The biggest lists are IT service providers (38), IT product companies (34) and digital marketing companies (10). Each list below is the top of its full ranking, ordered by rating, review volume and listing quality; no one pays for a position.

The businesses here list work in Poland. 87 of them have written a profile you can read before you get in touch.

What to check before you hire in Norway

  • Which legal entity signs, and which country's courts the contract names — the office you met may not be the company on the invoice
  • Where your data will actually be stored and processed, and whether that is allowed under the rules you are bound by
  • Who owns the work: intellectual property assignment has to be valid under the law of the supplier's country, not only yours
  • The overlap in working hours you will really get, and who is reachable when something breaks at your end of the day
  • The currency you are billed in, who carries the exchange-rate movement, and what the payment fees add
  • References from clients in your own market, not only in the supplier's — the ones who had to manage the distance
  • How the relationship ends: notice, handover of code, credentials and data, and what happens to staff assigned to you

Each section below is the top of that category's own ranking for Norway, so the two pages can never disagree. At the top of the largest of them, IT service providers, right now: Itera, Nettmaker AS and Restaff.

Add reviews or verified facts to your free profile to move up at the next edition; there are two ways to stand out now, and each one says what it is.

How is this ranking worked out?

A position here is earned, never bought. It is worked out from what a firm publishes and what has been verified about it:

  • Profile completeness: the details a buyer needs to judge a firm — what it does, who it serves, how it prices, who it has worked for
  • Earned trust: verification, awards and the other checks a firm has actually passed
  • Client reviews, where they exist: the rating is smoothed, so one five-star review cannot outrank a firm with a hundred good ones, and volume counts with diminishing returns

Be clear about the third one: client reviews are still rare across this catalogue, so on most lists today the order is set by the first two. A firm near the top is the best-documented and best-verified one we hold, which is not the same claim as the best one to hire. Use the list to build a shortlist, then check the firms yourself.

No firm can pay for a position. Sponsored listings are labelled and shown apart from this list. How rankings work
