+Top-level sections are Organization, Strategy, and Contribution, each with an independent sidebar. The first Organization page is Structure. It contains a dated public-evidence reconstruction, with named functions, job-advertised reporting lines, and explicitly marked planning assumptions. Citation URLs and checked excerpts are preserved in `research/organization/sources.json`; this is not an internally verified employee roster.
 
 Archify 3.0.1 is vendored under `vendor/archify/` from commit `d5a1333d7447c866a765adac7d4d062f2f02e4d2`. MIT and third-party notices are preserved. `diagrams/` holds editable JSON; `pnpm diagrams:build` validates and generates local standalone viewers before every site build. The iframe is sandboxed without same-origin permission. See `docs/contribution/diagrams.md` for capability analysis, authoring, boundaries, and upgrade procedure.

 Supply a text alternative below each diagram. The wrapper uses a local, base-path-aware iframe with a descriptive title, scripts and downloads enabled, and no same-origin or parent-navigation permissions. The Open full viewer button expands the diagram in a full-screen modal on the current page, with the same iframe sandbox. Close it with the Close button or Escape; focus returns to the opener. It does not open a new tab. The separate standalone HTML asset remains directly addressable and is not itself iframe-sandboxed, so publish only reviewed, trusted diagrams.

-This is **not Eldorado’s confirmed organization chart**. The roles and relationships below are test data demonstrating the diagram capability. Actual teams, reporting lines, and AI responsibilities will be defined separately.
-:::
+**Research snapshot: 2026-10-02.** This is a public-evidence reconstruction for AI strategy planning, **not a verified employee roster** or an internally approved organization chart.

-Select a node to inspect it. Use the viewer’s search, zoom, theme, and export controls, or open the full viewer for more space.
+Eldorado names **Vladas Jurkevičius — co-founder and CEO** and **Lukas Deksnys — co-founder and COO** on its official About page.[1]
 
-## Text alternative
+Its official careers site uses seven hiring categories: **Management, Product, Technology, Operations, Marketing, Finance & Accounting, and HR & Administration**. Those labels are directly evidenced; treating them as six peer departments beneath Management is a planning arrangement, not a published reporting hierarchy.[4]
 
-The example connects **Example leadership** to three sample functions: **Product**, **Engineering**, and **Operations**. These links demonstrate structure; they do not assert real reporting relationships at Eldorado.
+### Evidence legend
+
+- **E — Publicly evidenced:** a named leader, team, function or careers category explicitly appears in an official source. This does not establish every reporting relationship.
+- **J — Job-advertised:** a vacancy describes a role, mandate or reporting line. The position may be unfilled or newly created.
+- **A — Assumed:** a proposed grouping or missing team boundary used for planning, not a claim about Eldorado’s current structure. Dashed connectors identify assumed placements.
+
+## Department overview
+
+<ArchifyDiagram name="organization-structure" title="Eldorado organization — evidence and assumptions" />
+
+**Text alternative:** Management is shown above Product, Technology, Operations, Marketing, Finance & Accounting, and HR & Administration. All six placements beneath Management are assumed. The department names come from the careers taxonomy; the notes in the viewer identify evidenced teams and proposed subdivisions. This view does not assign every function directly to the CEO or COO.
+
+## Departments and teams
+
+The following separates **named teams** from **roles, capabilities and domains**. A function mentioned in a vacancy is not automatically a separately staffed team.
+
+| Department / function | Publicly evidenced teams, roles or domains | Assumed completion for planning |
+| --- | --- | --- |
+| **Management** | **E:** CEO Vladas Jurkevičius and COO Lukas Deksnys. **J:** CTO and CMO are referenced as reporting managers.[1][8][12] CFO is advertised.[5] No incumbent names are inferred for those three roles. | **A:** a leadership coordination layer across the six functions. Exact executive reporting lines, Board membership and decision rights remain unverified. |
+| **Product** | **E:** Order/Orders team; Categories design team, with Boosting & Currency scope; Data Team appears in the ranking Data Scientist vacancy metadata. Data classification and product design evidence.[9][13][14] **J:** Sellers and Operations product-owner domain, including Seller Portal, integrations, onboarding, balances/withdrawals, invoicing and support tooling.[15] | **A:** treat Sellers & Operations as a cross-functional product squad for planning, not a proven standalone team. Do not duplicate Data as a separate peer department. |
+| **Technology** | **J:** Head of Engineering → Group Engineering Managers → Engineering Managers → engineers. AI Architect reports to CTO and starts solo. Technical Architect is named as an infrastructure/security partner; IT Engineer is advertised for identity, device management and internal SaaS.[6][8][10] | **A:** CTO → Head of Engineering. Proposed shared platform/reliability and security capability groups, with staffing and reporting unverified. Do not turn AI Architect into an established AI department. |
+| **Operations** | **E:** Customer Support, Trust & Resolution, Risk & Fraud. **J:** QA Specialist (Operations) reports directly to COO; separate support/resolution Team Lead mandates cover specialist teams.[11][17][18] | **A:** COO ownership of the wider Operations function and its team-lead escalation chain. Only the QA Specialist’s direct COO line is explicit in the reviewed sources. |
+| **Marketing** | **J:** Brand Team Lead reports to CMO. **E:** the wider Marketing team names Creative, SEO, PPC & Affiliate, Influencer, and CRM; brand scope includes organic social, community and brand partnerships.[12] | **A:** model these named disciplines as planning workstreams under Marketing. Separate team managers, headcounts and each discipline’s direct CMO line are not established. |
+| **Finance & Accounting** | **E:** Finance team / hiring category. **J:** CFO remit includes planning, reporting, cash/capital, tax, compliance, financial risk and payments; it describes partnership with CEO and Board, not an explicit reporting line.[5] | **A:** FP&A; Accounting/Tax/Controls; Treasury/Payment Operations as three capability groups. These are inferred subdivisions, not proven staffed teams. Financial risk is not the same thing as the Operations Risk & Fraud team. |
+| **HR & Administration** | **E:** Talent Acquisition team / role category. **J:** full-cycle IT and non-IT recruitment, partnering with hiring managers.[16] | **A:** People Operations and Office/Administration alongside Talent Acquisition. Separate teams and the HR leader’s reporting line remain unverified. |
+
+The Sellers and Operations posting establishes a **product domain**, not a named Sellers department. Its mandate crosses seller-facing features, operational tooling and marketplace infrastructure.[15]
+
+## Reporting lines supported by vacancies
+
+<ArchifyDiagram name="organization-reporting" title="Eldorado reporting lines — advertised and assumed" />
+
+**Read arrows as manager → role/team.** Solid **J** connectors are explicitly described in vacancies. The dashed **A** link between CTO and Head of Engineering is the only inferred link in this diagram. Separate rows are not connected because their upward reporting lines were not established.
+
+| Manager / leader | Role or team below it | Status and scope |
+| --- | --- | --- |
+| Head of Engineering | Group Engineering Manager | **J:** explicitly reports directly to Head of Engineering; the vacancy describes managing 4–5 Engineering Managers.[6] |
+| Group Engineering Manager | Engineering Manager | **J:** explicitly named manager in the Engineering Manager vacancy.[7] |
+| Engineering Manager | Software engineers | **J:** leads a team of around five engineers. This is the advertised span, not a count of all current engineering teams.[7] |
+| CTO | AI Architect | **J:** explicitly direct; a new individual-contributor role, starting solo with a possible future team.[8] |
+| COO | QA Specialist (Operations) | **J:** explicitly direct; independent quality work across Customer Support, Trust & Resolution, and Risk & Fraud.[11] |
+| CMO | Brand Team Lead | **J:** explicitly direct; brand, organic social, community and brand partnerships remit.[12] |
+| Customer Support / Trust & Resolution Team Leads | Their specialists | **J:** support/resolution leadership advert describes teams of 5–10 specialists; the resolution-specific advert also states 5–10. Their own upward manager is not stated.[17][18] |
+| CTO | Head of Engineering | **A:** plausible technology reporting arrangement, retained only as a planning assumption. |
+
+Product Owner, Tech Lead and Product Designer are described as collaborating on product direction. That is evidence of cross-functional work, **not** evidence that one line-manages the others.[13][14]
+
+## What this means for AI strategy
+
+**Research interpretation, not an approved roadmap:** use the evidenced organizational owners rather than inventing one central AI department.
+
+- **Engineering enablement:** the AI Architect vacancy focuses on engineering output, adoption, standards and security under the CTO—not ownership of every business AI initiative.[8]
+- **Marketplace intelligence:** Product/Data has an advertised ranking and recommendations remit, including experimentation and learning-to-rank.[9]
+- **Operations quality:** operational QA explicitly includes auditing AI-handled support and LLM-assisted scoring; customer support leadership includes AI-assisted support and automation.[11][17]
+- **Planning assumption:** coordinate these three areas with Product, Operations, Technology and Finance owners. Whether to create a cross-company AI steering group is a future decision, not a finding about current organization.
+
+## Limits and validation questions
+
+- **No complete internal chart was found in the reviewed public sources.** This is not a claim that none exists. Research prioritized official About, careers, vacancy and legal pages; it is not an exhaustive employee or vacancy census.
+- **Job postings are time-bound recruitment evidence.** A vacancy can describe a future role or team. Names, staffing, budgets and every executive reporting line still need company confirmation.
+- **No reliable total headcount is asserted.** The careers homepage itself contains both “150+” and “200+” descriptions; do not use either to derive department sizes.[2]
+- **Legal entities are not departments.** The Terms of Service names GWD Processing FZCO, Eldorado Sales LLC and Halfway House OÜ collectively as Eldorado. This establishes contracting language, not a parent/subsidiary hierarchy or the employing entity of each team.[3]
+- **Keep scope distinctions:** marketplace Risk & Fraud, financial risk, AI security, and corporate compliance may collaborate but should not be collapsed into one assumed reporting chain.
+
+Before using this as an operating model, confirm: **(1)** which advertised roles are filled, **(2)** executive and functional reporting lines, **(3)** product squad membership and engineering matrix, **(4)** ownership of Payments, Legal/Compliance and Data, and **(5)** the real team roster and capacity. Replace each **A** only when evidence is supplied.

+# Organization research — 2026-10-02
+
+Public-evidence reconstruction, not an approved internal org chart. The canonical reader-facing report is `docs/organization/structure.mdx`. `sources.json` preserves retrieved URLs, access dates and verbatim excerpts checked against fetched page text with the grounded-citations evidence matcher. No private employee data or application forms were accessed.
+
+E = publicly evidenced names/categories/functions; J = job-advertised roles and reporting lines, not proof of occupancy; A = planning assumptions. The diagrams carry the same distinction. Department placement beneath Management is a model, not a proven reporting chain. Legal entities and hiring categories must not be conflated with departments.
+
+Coverage: official About, careers index and selected job detail pages plus legal Terms. The jobs index was not treated as an exhaustive personnel roster. Search-engine discovery was unhelpful (Google traffic challenge; Bing irrelevant results); all factual findings rely on directly fetched official sources. Exact headcount and unnamed incumbents are deliberately omitted. Current-role dates are access dates, not proof of appointment dates.
+
+Update source excerpts and access dates, revise the report and both diagrams together, then run `pnpm verify`, `pnpm typecheck`, `pnpm build`, `pnpm verify:build` and browser checks before publication. Revalidate recruitment evidence rather than treating an old vacancy as a permanent org fact.
