Adam Hadley is QuantSpark Limited's sole currently listed director and its registered person with significant control. The official register lists one officer, no resignations, appointed 1 August 2016. The active PSC entry, notified the same date, states ownership of 75% or more of shares, 75% or more of voting rights, the right to appoint or remove directors, and significant influence or control. These are filed rights, not a precise share percentage or proof that nobody else owns shares. Companies House warns that it does not check the accuracy of filed information. Sources: [officers](http[local research file] active-role/appointment entry; [PSC](http[local research file] sole active entry and nature of control.
[Company overview](http[local research file] identifies company 10304694, an active private company incorporated 1 August 2016. It was formerly Congent Strategy and Analytics Limited until 10 July 2017. The latest accounts are for 31 July 2025. The accounts themselves specify a private company limited by shares (PDF5/printed3). This is a different legal entity from Online Harms Foundation, company 11656320, which is limited by guarantee without share capital.
The prior retained OHF PSC record identifies QuantSpark Limited as its controller with 75%+ voting rights and director appointment/removal rights. That yields a documented corporate-control chain Hadley → QuantSpark → OHF, with different rights at each step. TAT identifies OHF as its implementer. The chain does not by itself show Hadley or QuantSpark choosing a particular TCAP entry, setting the verification taxonomy, or receiving instructions from a public donor. Reused source: [OHF PSC](http[local research file] retained ../private-verification-wave-2026-09-09/tat-psc.html; current packet reread its nature-of-control passage. The earlier tat.md holds identity and original custody.
[Latest original QuantSpark accounts](http[local research file] year ended 31 July 2025, were approved by director Mr A I Hadley on 9 July 2026 and filed 15 July 2026. The filing is unaudited and uses the small-companies regime. All 11 pages were visually read. The director elected not to file the profit-and-loss account (PDF3/printed1); the public statements therefore do not disclose annual turnover, annual profit, customer concentration or a project margin. Amounts are sterling, rounded to the nearest pound (PDF5/printed3).
The decisive reciprocal evidence is note 10, PDF10/printed8, identifying OHF as connected through common control and a common director:
| QuantSpark's disclosed relation to OHF | FY/as at 31 July 2025 | 2024 comparative | Evidence state |
|---|---|---|---|
| Consultancy and other services invoiced, net of VAT | £913,095 | £2,160,943 | Invoiced service amount; not a bank receipt |
| Amount owed in respect of those services at year end | £1,374,157 | £1,234,895 | Outstanding receivable; not current-year revenue |
| Amount owed for recharged expenses at year end | £180,769 | £52,816 | Separate outstanding receivable |
| Sum of the two disclosed outstanding components | £1,554,926 | £1,287,711 | Our arithmetic; not an additional transaction |
The retained OHF accounts, PDF7/printed5 note7, report £913,015 invoiced by QuantSpark during 2025 and £1,554,927 owed at year end. Its 2024 comparatives are £2,160,943 invoiced and £1,287,711 owed. The 2025 statements therefore differ by £80 on the invoice amount and £1 on the sum of outstanding components; the 2024 figures reconcile. Preserve each filing's figure and description. The QS invoice figure expressly says net of VAT; the OHF sentence does not specify a VAT basis. The acquired records do not explain the small differences, and they do not warrant an allegation of misstatement or a manufactured reconciliation.
This is useful clarification of OHF's creditor dependence: the supplier describes substantial unpaid services and expenses, rather than leaving the entire balance unclassified. It does not prove that the entire balance is a cash loan. OHF's separate going-concern note says it relies on loans from QuantSpark and records the director's assurance that amounts would not be recalled in the following 12 months. The public reciprocal note does not supply the loan agreements, interest/security terms, repayment schedule, whether any amount is subordinated, or which balance components the assurance covers.

QuantSpark reports positive net assets of £3,961,806 and cash of £922,739 at 31 July 2025 (PDF3/printed1). Those company-wide balance-sheet figures do not establish the source of funds lent to OHF, available unrestricted cash for TCAP, or the profitability of the OHF relationship. The filing's note 10 also includes an unrelated connected-company loan; that does not explain the OHF amounts and no branch into that company was opened.
QuantSpark's [20 April 2026 article](http[local research file] describes its AI/software consultancy business and identifies Adam Hadley as CEO and founder. Its author capsule expressly says he also runs Tech Against Terrorism. This is a direct company-owned statement of shared leadership, corroborating a professional connection beyond the register; it is not an OHF management contract or a specification of his classification-approval powers.
The article markets services to private-equity firms and their portfolio companies. That establishes its stated customer focus, not ownership of QuantSpark by a private-equity fund, funding of TAT by those customers, or a transfer from an unnamed asset manager. No company-owned contract-level explanation of the OHF loan/service arrangements was located in this bounded pass. A later exact-domain query repeated the leadership capsule; no wider biography or client-network expansion followed.
The next discriminating records are the QuantSpark–OHF consultancy agreement and related-party approval record, the loan/credit agreement and any standstill confirmation, and the intercompany reconciliation/payment ledger with project codes. Custodians are the two companies and their finance advisers. Joined to actual donor agreements, those would establish rates, earmarked projects, invoice settlement, repayment conditions and any reserved approval rights. They would also resolve the small reciprocal differences. A controlling person's registration or matching year-end balance cannot supply those facts.
The strongest defensible finding is concentrated corporate control combined with a disclosed supplier-creditor relationship. A commercially useful support structure, creditor dependence, and project-specific donor conditions can coexist. Which decisions each participant actually controlled still requires the operative agreements or decision records. No public-sector award is routed into these invoices or into an individual moderation decision in this packet. UK contracts and Canadian awards are separate concurrent lanes.
Six originals were retained by ordinary unauthenticated GET; qs-captures.json records exact URLs, timestamps, hashes and reading scopes. The official accounts web-reader click returned an Internal Error; one ordinary GET of the filing's direct PDF succeeded. No other retry or access workaround occurred. The scanned 11-page PDF has no usable text layer. qs-accounts2025.txt contains only empty page headings and is not a readable transcription. Local qs-accounts-p1.png through p11.png were all visually inspected. No earlier accounts or confirmation statement was acquired: the latest filing supplies 2024 comparatives and no material dated control change required another filing.
The company overview, sole PSC entry, officer role/date and latest-account filing row were read. The complete substantive company article and author capsule were read from retained HTML; unrelated client-performance claims are not findings. The initial forest-tail output was truncated; the complete selected latest entry was then reread. Web search output is discovery only except the explicitly read company source. Original custody includes public-register fields that are deliberately excluded from this narrative.
