Frequently asked questions
What
What
everyone asks.
Do I need to be a resident of the UK or the US to form a company?
No. You can form an LTD in the United Kingdom or an LLC in Delaware while being a resident of Spain or any other country. We take care of the required registered office address and legal representation.
How long does the whole process take?
UK: between 24 and 72 hours from signing. Delaware: between 5 and 10 business days. After that, add a few more days for banking (Wise/Mercury). In total, you can be up and running in under 2 weeks.
What's the difference between a UK LTD and a Delaware LLC?
The UK is ideal if your business is focused on Europe and EU/UK clients. Delaware is preferred for raising with American VCs, international e-commerce, or if you plan to operate in the US. We'll help you decide on the briefing call.
What about taxes? Will I be taxed twice?
There are double taxation treaties between Spain, the UK and the US that prevent you from paying twice. We handle tax optimization in the Pro plan and connect you with Spanish advisors if you need to file in Spain.
Do I ever need to travel to the UK or Delaware?
No. The whole process is 100% online, including opening a bank account (which we do remotely with Wise or Mercury). You can travel if you want to visit the office you use as your registered office address, but it's not required.
Can I cancel anytime?
Yes, no lock-in. If you decide to close the company, we also handle the legal dissolution with Companies House or in Delaware (one-off cost).
What's included in the Standard plan vs Pro?
Standard covers the essentials: company formation, registered office address, monthly bookkeeping and annual accounts filing. Pro adds tax optimization, legal advice, Confirmation Statement, priority WhatsApp and quarterly calls.
What happens if I have questions after forming my company?
Tienes un asesor asignado accesible por chat en el panel y email. En plan Pro además WhatsApp y calls trimestrales de revisión. No hay tickets genéricos ni "el departamento correspondiente te responderá".

I used to pay $500 with Stripe Atlas. Now I pay $21.99 a month with Aiden and I have a Spanish-speaking advisor. Total game changer.

I migrated my LLC from Delaware where another company managed it. Aiden rescued it, cleaned it up, and keeps it running for a lot less.

I didn't want to set up an SL in Spain with a sole trader accountant at €300/month. A UK Limited with Aiden costs me €20 and I get more tools.

Aiden Pay lets me charge clients through Stripe with no markup. Stripe Atlas charged me an extra fee on top of Stripe's own fee.
