Scandinavian quality for US brands

The number one reason brands stop scaling, is too few ads. Without enough creative volume, the algorithm runs out of signal and your costs go up. We test 100+ ads a month so the data tells us what works.

At your spend level, the algorithm has enough budget to learn from this volume. Most brands run a fraction of this, that's why they plateau.

US and Europe connected

No more juggling freelancers, agencies, and creative teams. One partner, one system, ads, creatives, and tracking all working together to grow your bottom line.

Meta Ads Management

Full campaign management across Facebook and Instagram. Account structure, audience architecture, bidding strategy, and daily optimisation driven by real conversion data.

Static and Video Production

High-volume static image ads and video content produced by our in-house creative team. Scroll-stopping formats built for performance, not just aesthetics.

UGC Content Production

We source and brief creators to produce native-style video ads that feel organic and sell hard. Hook-focused, brief-driven UGC built to convert.

Google Ads

Shopping, Search, and Performance Max campaigns managed by specialists. Feed optimisation, bidding, and conversion tracking so every click has a clear path to purchase.

Deep Technical Tracking

Server-side tracking, custom conversion events, and cross-platform attribution so every dollar of ad spend is tied to actual revenue, not flattering platform-reported numbers.

Creative Strategy

Angles, hooks, and messaging frameworks built on market research and competitor analysis. The brief is the product. Every creative decision is intentional, not instinct.

To the US founders we have been talking to,

We built Curve inside Scandinavia, running ads in one of the most design-literate and ad-skeptical markets in the world. Every ad had to earn its click before it could earn a sale. That discipline forged a methodology we now run for US brands as well, managing close to $1 million in monthly ad spend across the US and Europe.

We work like obsessives. We test constantly. We try everything. We never stop pushing. That is how Curve grew 700% in 2024, and that is how we build inside every account we take on.

Most US agencies have never run a campaign outside North America. Most European agencies have never cracked a US algorithm. We have done both, with the same team, for brands like Nicotinos, Earthing Harmony, Norse Organics, and QPaws.

We do not get paid unless we create sales for you. No Curve, No Pay. If you are a US founder looking for a sharper creative edge, or a partner who can open European markets without a six-month discovery period, this is what we live for.

With conviction,

Questions from US founders

Why should a US brand hire a Scandinavian agency?
+
Because Scandinavia punishes mediocre creative. Consumers there are design-literate, skeptical, and see through ad language in seconds, which forced us to build a tighter creative and testing methodology than most agencies ever have to. That same methodology runs inside US accounts today, with creative that earns the click before it earns the sale. Brands like Earthing Harmony and Nicotinos already use it here.
Do you already run ads in the US?
+
Yes. We manage close to $1 million in monthly ad spend across the US and Europe. Our US portfolio includes Earthing Harmony in wellness and Nicotinos scaling DTC subscription across both sides of the Atlantic.
Can you open European markets for a US brand?
+
Yes. We have done it for Nicotinos and multi-market apps like QPaws across twelve countries. We handle market-specific creative, local language, currency, and the structural differences in consumer buying behavior across Europe, so you do not lose six months trying to figure out who to hire.
How does the performance-based model work?
+
We take a percentage of the revenue we drive. No flat retainer. The exact structure is built around your margins and current spend, and we agree on it together before starting. If we do not create sales for you, you do not pay us.
Do you handle creative production too?
+
Yes. We produce static image ads, UGC video content, and motion graphics with our in-house creative team. Media buying without creative iteration is only half the equation, and we run both sides at volume.
Which ad platforms do you manage?
+
Meta is our strongest platform. We also run Google Ads at scale, which is where Norse Organics grew. TikTok and Snapchat are available where they convert for your category. We start where your buyers are, not everywhere at once.
How quickly do we see results?
+
9 in 10 of our clients see a bigger bottom line within 45 days. Significant scaling usually happens from month 2 onward as winning concepts compound and budgets follow the data. Onboarding from contract to first ads live is typically 10 to 14 days.
