Best Agency for European Brands Entering the US: How to Choose.

The best agency for European brands entering the US is one that runs the commercial side of the launch (market read, positioning, storefront, Amazon US, paid media, retail outreach and reporting) as one plan, and works next to your US attorney, accountant and customs broker instead of pretending to replace them. It should also tell you which channel it would test first and how it will measure that test against margin, not clicks.

This guide covers how to choose that partner. For the full launch sequence, see our US expansion plan for foreign brands, and for how we run this work for European companies, see US market entry for European brands.

What a US entry partner handles and what your advisors handle.

A common way US launches stall: nobody owns the whole plan. No one checks that the US price covers duty, fees and returns. Split the work clearly from the start.

• Your US entry agency: market and competitor read, US positioning and copy, claims review, storefront and Amazon US setup, paid media, review generation, retail and distributor materials, and one reporting view across channels.
• Your attorney: entity choice and formation, contracts, trademark filings and product liability questions.
• Your accountant: federal filings and state sales tax registration. A foreign-owned single-member US LLC, for example, is treated as a corporation for limited IRS reporting purposes and must file Form 5472 with a pro forma Form 1120 each year, even with no income tax due.
• Your customs broker and 3PL: classification, duties, importer of record, labeling checks and US warehousing.

The agency still needs those answers, because they feed pricing and channel choice. Since the 2018 Wayfair decision, states can require remote sellers to collect sales tax based on economic presence alone, and thresholds differ by state; Texas, for example, uses a $500,000 safe harbor at the time of writing and lets remote sellers that sell only through a certifying marketplace skip their own permit. Our guide to US sales tax for foreign sellers covers nexus and marketplace rules in more depth. On imports, the US suspended duty-free de minimis treatment for shipments from all countries on August 29, 2025, so a plan that ships single orders from Europe needs a landed cost model that includes duty on every parcel.

US positioning and localization.

A localization partner should adapt the brand for American buyers without stripping out what makes it European.

• Language: US spelling and vocabulary throughout (color, not colour; sneakers, not trainers), written for the terms Americans type into Google and Amazon, not translated from a German or Italian master.
• Sizes and units: US clothing and shoe sizes, inches and pounds on product pages. FTC rules under the Fair Packaging and Labeling Act require net quantity on covered consumer packages in both metric and inch-pound units.
• Pricing: American shoppers expect prices shown before sales tax, with tax added at checkout. Build US prices from landed cost, fees and competitor price bands rather than converting a VAT-inclusive euro list.
• Claims: the FTC requires a reasonable basis for objective claims before the ad runs. "Clinically tested", "sustainable" or "lasts twice as long" each need evidence on file. Origin and craftsmanship work best as checkable specifics: materials, testing, warranty and returns.
• Reviews: the FTC rule on consumer reviews and testimonials bans fake reviews, reviews bought on the condition they are positive, and undisclosed insider reviews. A US launch plan should build reviews through legitimate programs and post-purchase requests.

Channel choice, US presence and test budgets.

Consumer brands and B2B companies need different first moves, and an agency that pitches the same plan to both is a warning sign.

Consumer and DTC brands. Most test through a US Shopify store and Amazon US at the same time, priced so neither undercuts the other. Retail and distributors usually follow once sell-through data exists. An Amazon US partner should handle Brand Registry, listings, A+ content and inventory planning, not just ads.

B2B and SaaS companies. The go-to-market is a pipeline, not a storefront. That means US positioning against US competitors, a site and landing pages written for US buyers, paid search on high-intent terms, lead capture wired into a CRM, and follow-up that happens in US business hours. US enterprise buyers often send security and compliance questionnaires early, so have answers ready before you spend on demand.

A Berlin or Milan team is nine hours ahead of California. If every decision waits for an overnight email, the test runs at half speed. Look for a partner whose day overlaps European mornings and who can be your team on the ground for US meetings and retail calls.

Budget pacing matters more than the total. A sound test market plan starts in a few states or regions, sets a margin target per channel, and grows spend only where the unit economics hold. Plan on at least twelve months of budget and attention, since setup takes the first months and paid media needs time to learn.

Criteria to judge a US market entry agency.

Questions to ask in the first call.

• Which channel would you test first for a business like ours, and why?
• What do you need from our broker and accountant to build the landed cost model?
• How do you review claims and copy before anything goes live in the US?
• Which states or regions would you start in, and what number tells you to scale or stop?
• What does the weekly report show, and is it built on margin or revenue?
• For B2B: how do leads get to our sales team, and who follows up while Europe is asleep?
• What happens in months 6 to 12 if the first channel works, and if it does not?

Red flags.

• A promise of US sales figures or Amazon rankings before they have seen your margins.
• Legal or tax advice delivered as fact rather than routed to your advisors.
• A plan that ignores duty, returns and marketplace fees when setting price.
• Review tactics that pay for positive reviews or rely on staff reviews without disclosure.
• No named owner on the agency side for the US plan as a whole.

How pricing usually works.

US entry agencies typically price in one of a few ways: a fixed-fee project for the market read and entry plan, a phased build for storefront and Amazon setup, then a monthly retainer for ongoing management, sometimes with a fractional growth lead embedded with your leadership. Some charge a percentage of ad spend or sales; ask how fees change as you scale. Media spend, Amazon fees, fulfillment and your advisors' fees sit on top of the agency fee, so budget for all of them in the test.

Where Theory Road fits.

Theory Road is based near Austin, Texas, and runs the commercial side of a US launch for foreign brands, coordinating with your legal, tax, customs and logistics advisors rather than replacing them. For European brands entering the US, that means a US market read and landed cost model built with your broker and accountant, positioning and claims review for American buyers, a Shopify store with US pricing, shipping and returns, and Amazon US listings, Brand Registry and A+ content through our e-commerce and Amazon practice. Google, Meta and Amazon Ads launch in a few test states first and are measured against contribution margin through our paid media practice, with one weekly view of spend, orders, returns and margin. Retail and distributor outreach follows once direct sales prove demand. Central time overlaps European mornings, and we schedule reviews in European working hours.

We are a fit for European consumer or B2B brands with proven home-market sales, ready to hold US inventory and commit at least twelve months of budget. We are not a fit for companies still testing product-market fit at home, or for teams that want their agency to form the entity, file taxes or clear customs. The wider program is on our US market entry page. If that sounds like your launch, tell us what you need.
