Get paid by customers worldwide — a US company, a US business account and card payments, applied for together.

For founders who want a proper way to get paid internationally

The LLC is only step one. The goal is a working payments setup.

Filing the LLC is usually the quick part. What makes it useful is the setup around it: a business account that can receive USD and international transfers, and card payments for your customers. We plan all three together from day one, so the company, the account and the card-payments application tell one consistent story about your real business.

That step is decided entirely by the bank or payment provider, not by any formation service. Founders get tripped up by things that have nothing to do with the LLC paperwork itself — an ineligible country of residence, a business description that doesn't match the website, an application submitted without understanding what the reviewer is looking for. We check these points before you apply, so each provider receives a complete, accurate application.

Specific, checkable behaviors — not a claim about nationality

• Written checklists, not verbal promises. Every step you need to take is written down and shared with you.
• Stated response times. Support windows and a 1-business-day response SLA are defined upfront.
• Two-person document checks. Formation documents go through a second-person QA pass before filing.
• Clear written timelines — including the parts that depend on third parties, like IRS EIN processing, and are out of our control.
• Honesty about limits. When something is outside what we can do or promise, we say so plainly instead of hedging.
• Founder-run. Kento Kimura formed his own US LLC, Haiburi LLC, in August 2026 and runs it himself as a non-US founder.

Everything in one all-in package

• US LLC filing, done for you
• EIN application (SS-4) for owners without a US Social Security Number
• An operating agreement template
• Formation document QA (two-person check)
• A compliance calendar for your new LLC
• Eligibility pre-check for Mercury/Stripe/Wise based on your country of residence
• Line-by-line review of your banking and payment applications before you submit them yourself, under your own identity
• A website and business-description consistency review to support your KYC applications
• An alternative-provider plan prepared upfront (e.g., Relay or Wise if Mercury isn't available where you live) — each provider decides independently
• An introduction to a PTIN-holding US tax preparer
• Kento Kimura personally leads your file: up to 8 video sessions over 6 months, a 1-business-day response SLA and a weekly written progress report

Five steps, start to finish

1. Free fit call. A free 20-minute call to understand your situation, confirm you're not in a sanctioned country or region, and check whether your country of residence is likely to work with Mercury, Stripe, or Wise.
2. Intake. You complete our intake form with your business details and identity information. We review it before any money changes hands for filing.
3. Formation. We file your US LLC, apply for your EIN (SS-4 for non-SSN owners), and prepare your operating agreement from our template. Every formation document goes through a two-person QA check before it's considered final.
4. Banking & payments prep. We prepare and review your Wise Business, Mercury (or alternative), and Stripe/PayPal applications line by line. You submit every application yourself, under your own real identity — approval is decided by the provider, not by us.
5. Hand-off & ongoing care. You receive your compliance calendar and an introduction to a PTIN-holding tax preparer. Support continues for the 6-month window included in the package.

About Kento

Frequently asked questions

Can I open a Mercury account if I don't live in the US?

It depends on your country of residence. Mercury does not currently accept founders living in certain countries, including Indonesia, the Philippines, Vietnam, Pakistan, Bangladesh, Nigeria, Nepal, Cambodia, Ukraine, Russia, and Belarus. We check your eligibility before taking any payment for banking-related work, and we consider alternatives such as Wise Business, Relay, or Airwallex case by case — those decisions are also made by the provider, not by us.

Will Stripe or PayPal approve my account?

We help you prepare a clean, consistent application and review it line by line before you submit it. Approval is decided solely by Stripe or PayPal based on their own underwriting — we cannot guarantee it.

Will this make my income tax-free?

No. We don't offer tax advice, and no formation service can make your income tax-free. A foreign-owned single-member LLC typically has US information-return duties, such as filing Form 5472 with a pro forma 1120. We explain this calendar and introduce you to a PTIN-holding US tax preparer for your US filings. Taxes in your home country remain your responsibility, with your own local advisor.

How long does the whole process take?

We give you a written timeline at the start. State filing and EIN issuance depend on the state and the IRS, and banking and card-payment reviews depend on each provider, so we do not promise a fixed number of days.

What's your refund policy?

Summary (your service agreement governs): full refund of the service fee if you cancel before we've filed anything. Once filing has started, government and agent fees already paid are non-refundable. For partially completed engagements, we refund on a pro-rata basis for stages not yet delivered.

I live in Japan — is this the right page for me?

This English-language, USD-priced page is for clients outside Japan and does not include Japan-specific tax coordination. If you're based in Japan or prefer Japanese-language support, visit our Japanese site for the Japan package.

Who can't use Haiburi LLC?

We cannot serve residents of OFAC-sanctioned countries or regions (Cuba, Iran, North Korea, Syria-related restrictions, Russian-occupied regions of Ukraine) or sanctioned persons. We also don't work with anyone looking for anonymity, nominee ownership, or tax advice.

Do you provide anonymity or nominee owners?

No. You pass normal KYC under your own real identity for every account you open. We don't offer nominee owners, we don't help hide beneficial ownership, and we don't help anyone bypass KYC.

Why isn't this the cheapest option?

It isn't, and if you only need a filing, cheaper do-it-yourself options exist. Our package covers the work that happens after filing — eligibility checks, line-by-line application review, written checklists, QA, and a human operator who answers you directly, within one business day.

What happens after formation — am I on my own?

No. The package includes a 6-month support window (video sessions, chat and email). You keep your compliance calendar after that window; ongoing annual-filing support can be arranged separately, with government and tax-preparer fees billed at cost or by quote.
