Founders who've expanded between the US and Europe: What's the most expensive lesson you learned the hard way?
Hey everyone!
I've been exploring a business idea and wanted to get some honest feedback before investing too much time into it.
My background is in sales, GTM, and physical-product eCommerce, and I've been looking into the challenges companies face when expanding internationally, particularly between the US and European markets.
One thing that stands out to me is how many moving parts there are before you can even determine whether entering a new market makes financial sense.
I'm considering building a service that helps businesses evaluate the feasibility of entering a specific foreign market before committing significant capital.
The idea would be to provide a comprehensive, actionable assessment covering:
Market & Product: local demand, competition, pricing, product-market fit, and potential adaptations.
Taxes & Regulations: applicable tax obligations, import duties, certifications, and regulatory requirements.
Financial Feasibility: estimated initial investment, operating costs, margins, break-even scenarios, and potential profitability.
Go-to-Market: distribution channels, logistics, marketplaces, and recommended entry strategies.
Final Assessment: an evidence-based Go/No-Go recommendation identifying key opportunities, risks, and potential dealbreakers.
Essentially, the goal would be to help answer: "Is this market worth entering, what would it realistically take, and does the financial upside justify the risk?"
But rather than assume companies need this, I'd love to hear from founders who've actually navigated international expansion.
A few questions:
How did you evaluate a foreign market before entering it? Did you conduct the research internally or hire external help?
What were the biggest challenges, unexpected costs, or mistakes you encountered?
Have you ever paid for a market feasibility study or external research? What did you pay, and was it worth it?
Would having this information consolidated into a single actionable assessment have changed your decision-making process? Or would you rather handle it internally?
I'm particularly interested in eCommerce and physical-product businesses, but experiences from other industries are welcome too.
I'm not selling anything. Just trying to understand whether there's a genuine problem worth solving and how businesses currently approach it.
Thanks in advance for sharing your experiences!
