Technology & business consulting · Stockholm

Clarity for your systems and your numbers.

Arnell Consulting is a boutique consultancy of two senior consultants — one in software, cloud and security, one in business controlling and financial analysis. No overhead, no complexity for its own sake.

What we do

Two disciplines, one team that speaks both.

From building and securing software systems to financial steering and operational analysis — we cover the full spectrum.

Our approach

Straightforward, by design.

Since 2005 we have worked closely with our clients to deliver solutions that are practical, well-crafted and lasting — pairing deep technical expertise with sharp business acumen.

  1. Understand the problem

    We start with your situation, not a template — what needs to change, and why.

  2. Apply the right expertise

    A senior consultant does the work — technology, finance, or both together.

  3. Deliver with clarity

    Results you can run, read and build on — documented and handed over cleanly.

The team

The people behind the work.

Two senior consultants with complementary expertise — one in technology, one in business.
