Holding-company payment route
Slimrock (Tallinn ledger vehicle)
Tallinn identifies Slimrock as one of his holding companies and records donations through it, including £2.5 million to ControlAI’s predecessor.
Two historical payments
The ledger reports £500,000 on 14 November 2023 and £2 million on 10 April 2024 to Secure Future Research. These are donor-reported disbursements, not evidence of payment for a particular creator or campaign.
Identity still to reconcile
The ledger footnote uses Slimrock Holdings. The property-financing account separately names Slimrock Investments Pte. Ltd.; common association with Tallinn does not settle legal identity.
