A guide for international founders entering the US · Practice area: Formation & Management
You’re talking to a US VC and they tell you, “we love the business — but you need to flip first.” Your home-country company is running just fine. What exactly are you supposed to flip?
TL;DR: A Delaware Flip puts a new US Delaware C-Corp on top of your existing home-country company. Your current shareholders exchange their shares for shares of the new US parent, and the home-country company becomes its subsidiary. It’s the standard pre-condition for raising from US venture investors.
What exactly is a Delaware Flip?
It’s a restructuring that makes your home-country company a subsidiary of a new Delaware C-Corp, with your existing shareholders becoming shareholders of that US parent.
You don’t shut down the original company — you place a US parent above it. Your home-country shareholders give up their existing shares and receive shares of the US parent in return (a share-for-share exchange). On the US side, the exchange is commonly structured under IRC §351, which allows tax-deferred transfers to a corporation the transferors control. The end state: a US company owns your home-country company, and investors put their money into the US entity they know how to work with.
Why do VCs require a flip?
Because many US venture funds simply won’t invest in anything other than the Delaware C-Corp they know.
US investors prefer Delaware C-Corps — legally familiar, and built for the stock structures venture deals need. That’s why term sheets often make “convert to a US structure before closing” an explicit condition. If you want the check, the flip is effectively a prerequisite.
Is a flip tax-free?
On the US side it can generally be structured that way. In your home country, it may not be.
This is the part foreign founders miss most often. Even when the exchange qualifies for tax-deferred treatment under US law, your home country may tax the share transfer — capital gains tax, stamp duty, or both, depending on the jurisdiction. The rules differ country by country, which is why the standard practice is to design the flip with a US lawyer and home-country tax and legal advisors working together, not sequentially.
When is the right time to flip?
Earlier is usually simpler — while the company’s value is still low.
If you transfer shares after the valuation has climbed, the home-country tax bill on the exchange can climb with it. So the general wisdom favors flipping early, at a low valuation. That said, some founders deliberately delay to capture home-country tax benefits first. There is no universal answer — it’s a case-by-case timing decision.
Once we flip, are we done?
No. IP, contracts, employees, and taxes all need to move — or at least be re-mapped — along with the structure.
Placing a parent on top is not the finish line. You need to sort out where the core IP sits, which entity employs whom, and which contracts belong where. Skip this cleanup and it resurfaces later — usually in due diligence, at the worst possible moment.
What does the flip mean for an international founder?
The flip is a gateway that exists only because you started outside the US.
A founder who incorporated a Delaware C-Corp on day one never thinks about flipping. Only founders who built their company at home face this — moving shareholders, IP, contracts, and tax positions under a US parent to plug into the US capital market. That makes the flip more than a procedure: it’s the moment your home-country track record gets connected to US venture capital. And it’s exactly why the design has to look at both countries at once.
A flip touches taxes and procedure on both sides of the border, so timing and structure should be designed before the term sheet forces your hand. If you’re weighing a flip ahead of a US financing, reach out for a consultation. We look at the US side and the home-country side together.
