Expanding to the US shouldn't mean juggling five vendors
Every piece — incorporation, banking, books, tax, compliance — goes to a different vendor, most of them traditional firms. Nothing connects, so everything waits on you, and the gaps and delays are where it costs you.
Fragmentation
5+ disconnected vendors for incorporation, banking, books, tax, and compliance — with no single owner.

Delays
A US EIN takes ~4 weeks without an SSN — before you can even open a bank account and start accepting US payments.

FAQ
Common questions, straight answers
Have a question that's not here? Email support@arclow.com and we'll reply within one business day.
Who is arclow for?
International founders setting up or running a US company from abroad. Whether you're incorporating now or already have an entity, arclow runs the banking, books, tax, and compliance.
What entity type do you recommend, and why?
Most international founders raising (or planning to raise) US venture capital incorporate as a Delaware C-Corp — it's the structure US investors expect, it supports standard stock options and financing terms, and it's the default across the VC ecosystem.
Do I need a US SSN or to visit the US?
No. We set up your company and get you a US business bank account fully remote — no SSN, no branch visit. You complete your own identity check (KYC), and we guide you through every step.
What about my home-country obligations, like the FX filing?
This is where arclow is different. Most services form your US entity and ignore your home country. We make sure your foreign-exchange (FX) declaration goes in the right order — before you wire capital — so you don't trigger a penalty back home. You file it at your bank; we guide you through it.
How long does the whole setup take?
Days, not months. On Day 1 we file your incorporation and EIN, and within about a week your entity and US address are live and your bank account can open — you don't wait for the EIN to be issued, only applied for. From there it comes down to clearing the bank's KYC (we guide you through it), then you connect Stripe and start taking payments. Your EIN finishes processing in the background, usually within ~4 weeks, without holding anything up.
I already have a US entity. Can I still use arclow?
Yes — skip setup and start with the running part. Connect your accounts and we take over your books, tax, and compliance.
Is my financial data secure?
Yes. Bank connections are read-only and encrypted, and your data is never shared or sold.
