Privacy policy
Last updated: November 14, 2026
This policy explains which personal data GreatCompany.ai collects through this website and the waitlist, why we do that and what your rights are. We keep it short and only collect what we need.
Who we are
GreatCompany.ai is SEO and GEO software, built in Groningen, the Netherlands. GreatCompany.ai is the US edition of Briljant and is operated from Heresingel 19, Groningen, the Netherlands, registered with the Dutch Chamber of Commerce (KvK) under number 95815287. We are the controller for the personal data described on this page.
Questions about privacy? Email hello@greatcompany.ai.
What we collect when you join the waitlist
When you join the waitlist, we store:
- Your email address
- Your website, if you fill it in
- The page and the spot on the page where you signed up
- How you reached our site, such as the referring website or campaign tags (utm parameters) in the link
- The country, state and city of the request, derived from your IP address by our hosting provider; we do not store the IP address itself, only a one-way hash of it to stop spam and abuse
Why we use it
We use your email address to send you one email when GreatCompany opens in the US, with access to your free report. We use your website to prepare that report. We use the source of your visit to understand which channels bring people to the waitlist. We do not sell your data and we do not send you anything else without your permission.
The legal basis is your consent, which you give by submitting the form. You can withdraw it at any time by emailing hello@greatcompany.ai; we then delete your signup.
Cookies and analytics
We store one functional cookie that remembers your cookie choice. Without your consent we do not load any analytics or advertising tools.
If you allow statistics cookies, we use PostHog (EU cloud) to see how visitors use the site, such as which pages are visited and which buttons are clicked. With that consent PostHog may also record anonymized session replays of how the page is used; text you type into form fields is masked. You can change your choice at any time through the cookie settings link in the footer.
We do not use advertising cookies on this site at this time.
Who processes your data
We use a small number of service providers that process data on our behalf:
- Vercel, which hosts the website and processes the waitlist form
- Supabase, which hosts the database of our application, where your waitlist signup is stored
- PostHog, which stores waitlist signups and, with your consent, site statistics, in its EU cloud
- Resend, which sends our emails, such as the notification of a new signup and the email when we open
How long we keep it
We keep your waitlist signup until GreatCompany opens in the US and for at most 12 months after that, unless you create an account. Statistics data is kept for at most 12 months. If you ask us to delete your data earlier, we do so.
Your rights
You can ask us which data we have about you, and ask us to correct, delete or export it, or to stop using it. This applies under the EU General Data Protection Regulation (GDPR), and we honor the same requests from residents of US states with privacy laws, such as California. Email hello@greatcompany.ai and we will respond within 30 days. We will not treat you differently for using these rights.
If you are in the EU and think we handle your data incorrectly, you can file a complaint with the Dutch Data Protection Authority (Autoriteit Persoonsgegevens).
International transfers
We are based in the Netherlands. Some service providers may process data outside the European Economic Area, including in the United States. Where that happens, it is covered by the EU-US Data Privacy Framework or standard contractual clauses.
Security
The site is only available over HTTPS, so data is sent encrypted. Access to waitlist data is limited to the people who need it to send the launch email.
Changes
When GreatCompany opens in the US, we will extend this policy with the data we process for the service itself, such as your account, connected Search Console and connected WordPress sites. The date at the top shows when this page was last updated.
