About Cairn
Cairn was started by a former operating partner who kept watching good companies stumble over messy numbers, not bad ideas. We step in as the finance function most founders don't have time to build themselves.
We're not a bank and we don't take equity in your raise. We get paid to make sure your numbers hold up under pressure — whether that pressure is a board meeting or a term sheet.

How we work with founders
01
We audit first
Before we touch a deck or a model, we go through your books line by line. Most financials fall apart under scrutiny.

02
We build the model
Together we build a forecast that survives hard questions — assumptions documented, scenarios stress-tested.

03
We stay in the room
We don't hand off a PDF and disappear. We join diligence calls, answer follow-ups, and help you get to a signature.

What's different about Cairn
Numbers first, story second
We don't open with a template. We start with your general ledger and only write the narrative once the math holds up.
An operator network
Our intros come from founders and investors we've actually worked with, not a cold spreadsheet.
We don't leave after the wire lands
Most advisors disappear post-raise. We keep working the model with you through the next two quarters.

Frequently asked questions
Who do you typically work with?
Early-stage tech founders, usually pre-seed to Series A. Most are based in the Nordics, but we've worked with companies across Europe. If you're building something real and thinking about your next raise, we're probably a good fit.
How much does it cost?
It depends on scope. Some founders need help with a specific raise, others want ongoing financial support between rounds. We'll give you a clear quote after an intro call — no surprises.
Do you invest in the companies you advise?
No. We're independent advisors. That means our advice isn't shaped by a cap table position — we're focused on what's actually best for you and your company.
How long does a typical fundraising engagement last?
Usually 2–4 months from first call to signed term sheet, though it varies. We stay involved through closing and help you set up reporting and governance for what comes next.
What if we're not ready to raise yet?
We'll tell you — honestly and early. Then we'll help you figure out what needs to happen first, whether that's traction, unit economics, or just a clearer story. Some of our best engagements started that way.
