Terms of Service
Last updated: October 2026
1. Who we are
Populai is operated by Cardiff Giant Ventures Limited, a company registered in England and Wales with company number 12322092. Registered office: Unit 12 Green Park, Coed Cae Lane Industrial Estate, Pontyclun, CF72 9GP. In these terms "we" and "us" mean Cardiff Giant Ventures Limited.
2. Acceptance of terms
By creating an account or paying for Populai you agree to these terms and to our refund policy. If you do not agree, please do not use the service.
3. The service
Populai provides decision rehearsal using simulated populations. Outputs are modelled perspectives, not predictions of how real individuals will behave, and should be used as one input among many.
4. Populai Monthly subscription
Populai Monthly costs £149 a month, including VAT. Each paid month includes 1 decision rehearsal with a population of up to 1,000 people. An included rehearsal that is not used in its month does not roll over.
The subscription renews automatically at the end of each monthly billing period, and you are charged the then current price, until you cancel. We will tell you in advance of any price change.
You can cancel at any time from your account. Cancellation stops the next renewal; your subscription continues until the end of the month already paid for. Part periods are not refunded.
5. Single and extra rehearsals
A single rehearsal costs £249, including VAT, as a one-off payment and does not need a subscription. Active subscribers can buy an extra rehearsal for £99, including VAT. Each covers one rehearsal with a population of up to 1,000 people, is added to your account once payment is confirmed, and does not expire.
Credits bought before these terms keep their value: 1 credit is a 300-person run, 2 credits a 600-person run and 3 credits a 1,000-person run.
6. Payment and VAT
Payments are processed by Stripe, which acts as the seller of record for your purchase and issues your receipt. Prices are in pounds sterling and include VAT. Access changes only once a payment has been confirmed.
7. Refunds and cancellation rights
Our refund policy forms part of these terms. By starting a run you ask us to supply the service immediately, and you accept that a rehearsal cannot be refunded once used. Nothing in these terms affects your statutory rights.
8. Your responsibilities
You are responsible for keeping your account credentials confidential and for all activity under your account. You agree to use the service lawfully and not to upload personal data you have no right to use.
9. Intellectual property
The Populai software, content and brand are owned by Cardiff Giant Ventures Limited. You keep ownership of the decisions and material you submit, and of the outputs generated for you.
10. Limitation of liability
Populai provides insights for information only. We are not liable for decisions made on the basis of its outputs. Our total liability in any 12-month period is limited to the amount you paid us in that period. Nothing limits liability that cannot be limited by law.
11. Governing law
These terms are governed by the laws of England and Wales, and its courts have jurisdiction.
