The app stores all your financial and legal information. That's why we designed it with the same level of security as your bank.

Passwordless access

A 6-digit code sent to your email every time you log in. No passwords to forget or reuse.

Face ID · Touch ID

Quick access to the app with biometrics. Your face or your fingerprint — no code to type every time you open it.

End-to-end encryption

Your data travels and is stored encrypted. Not even Aiden can read its content in transit.

Servers in the EU/UK. We comply with GDPR, the ICO (UK) and all applicable data protection requirements.

The intelligence of Aiden,
working with you.

Deployed across all of Aiden Emails, website copy, replies to customers. Lunnar learns how you write and takes over — it almost feels like magic.
Your greatest ally An unpaid invoice, a domain up for renewal, a website running slow. It tells you beforehand, not once it's already a problem.
Sums up what you don't have time for. Forty unread emails become five lines with what you really need to look at today.
Helping you 24 hours a day Even at 3 in the morning, our AI Lunnar helps you by connecting to your account and sorting out your issues on its own
Builds your website with you watching.
Builds your website with you watching. You tell it what you do and it puts together a first version. From there you change it by talking, not by touching code.
And it keeps nothing of yours. What you tell it is used to help you. It doesn't train anyone else's models and isn't sold to anyone.

Everything you you might be wondering.

Is the app included in my plan?

Yes. The app is free and included in every Aiden Startup plan. There's no extra cost, and no premium features exclusive to the web version.

How do I log in if I don't have a password?

When you open the app, enter your email and we'll send you a 6-digit code. Type it into the app and you're in. Your session stays saved on the device, so next time you only need Face ID or Touch ID.

Does it also work from a browser?

Yes. All the app's functionality is also available at startup.aiden.es from any browser. The app is there for quick access and push notifications, but the data is exactly the same.

When will it be available for Android?

We're working on the Android version and will update this page as soon as it's ready. In the meantime, Android users can use startup.aiden.es from the browser, with a fully responsive experience.

Can I upload documents from the app?

Yes. You can upload invoices, receipts and documents from your gallery, snap a photo instantly with the camera, or forward emails to books@aiden and they'll appear in the app automatically.

Can my advisor send me things through the app?

Yes. When your advisor sends you a draft filing, a document to sign, or an important notification, you'll get a push alert and see it directly in the relevant section.
