Altman investigation network

8595 Pelham Rd Suite 400 #309, Greenville SC hosts 48+ Altman-linked entities — shared commercial mailbox functioning as family office address for all Hydrazine Capital, Apollo Projects, Structure Fund, and personal holding vehicles

Graph node '8595 Pelham Road, Greenville, SC (Altman family office)' connects Tools for Humanity Corporation and feeds into the main 68-node component. Address documented hosting: 950 LOMBARD LLC, 9POINT VENTURES LLC, ALTMAN FAMILY LLC, ALTMAN HOLDCO LLC, APOLLO PROJECTS GP LLC, APOLLO PROJECTS LP, HYDRAZINE CAPITAL I/II/IV funds and GPs, HYDRAZINE CAPITAL II SPV LLC, Elfin Cove Capital LLC (Beckwith), Structure Fund I GP/LP, SAM ALTMAN QUALIFIED OPPORTUNITY FUND LLC, Uncommon Ventures, Amberley Properties, and more. Mass re-registration event on 2022-07-15 moved all entities to this address, suggesting Serralta took operational control of family office that day.

Jennifer Serralta is structural bridge between Altman personal entities and OpenAI governance cluster — betweenness rank #10, only non-subject node with non-zero clustering coefficient

Serralta connects to Sam Altman (familial + corporate), ALTMAN HOLDCO LLC (corporate), 950 Lombard LLC (corporate), 8595 Pelham address node (corporate), and Michael Shetterly (corporate). Clustering coefficient 0.10 — highest of any non-subject node. Degree=5, betweenness=0.118, brokerage=0.90. The 2022-07-15 mass restructuring consolidated Altman financial architecture under her registered address. She is the one node whose removal would disconnect personal holding entities from the address cluster.

Graph density 0.018 with 14 structural holes — all high-degree nodes (Tools for Humanity, Microsoft, Hydrazine, Samuel Altman node) have brokerage score 1.0, indicating Altman mediates all connections and no sub-networks have formed independent links

All 14 structural hole nodes have neighbor_density=0.0 and brokerage_score=1.0 except Sam Altman (0.99) and Jennifer Serralta (0.90). This means neighbors of each hub do not know each other — every connection routes through the primary subject. The graph has 101 nodes, 90 edges, density 0.017822, and 14 connected components. The main component (68 nodes) contains all key entities. The lone clique (size 3) is Altman + Serralta + 950 Lombard LLC — a pure ownership triangle. This star topology suggests the investigation has primarily documented direct Altman relationships rather than lateral ties within his network.

Greg Brockman ranks #2 in betweenness centrality (0.484) but has only 2 findings — highest-ratio coverage gap among named persons; bridges Musk-Altman and OpenAI governance to plaintiff networks

Brockman's betweenness (0.484) is second only to Sam Altman (0.850) and substantially above Elon Musk (0.452), OpenAI Inc (0.408), and Microsoft (0.376). Despite this, Brockman has only 2 findings and degree=2, suggesting the graph accurately reflects his positional importance (as a named party in Musk v. Altman litigation and former OpenAI President) without adequate documentary coverage. He bridges: (1) the Musk-Altman legal dispute to the broader OpenAI network and (2) OpenAI governance history to current structure. His departure from OpenAI (Aug 2024) and subsequent silence makes him a high-value but under-documented node.

OpenAI lobbying cluster (Akin Gump, DLA Piper, David Schwietert, Jonathan Hiler, OpenAI OpCo) forms isolated 5-node component disconnected from main Altman network — no bridge to personal financial vehicle cluster documented

Component 3: Akin Gump Strauss Hauer & Feld, DLA Piper LLP (US), David Schwietert, Jonathan Hiler, OpenAI OpCo LLC. This is an entirely separate connected component from the 68-node main component. The lobbying cluster lacks any documented connection to Altman's personal entities (Hydrazine, Apollo Projects, family office). Similarly, the Troon Pacific component (Gregory Malin, Nigel Chanter, Impact Builders LLC, Eight Forty One LLC) appears in its own 5-node island. This isolation may reflect genuine separation or investigative coverage gap — lobbyists may connect through Altman himself rather than through documented entities.

Investigation graph contains duplicated entity nodes inflating metrics: 'Sam Altman'/'Samuel Altman', 'Hydrazine Capital Management, LLC'/'Hydrazine Capital Management LLC', 'Tools for Humanity Corporation'/'Tools for Humanity Corp' each appear as separate nodes

Degree centrality: 'Samuel Altman' ranks #5 with degree=8, betweenness=0.1562 (rank #6). If merged with 'Sam Altman' (degree=46), the combined node would have degree~50. 'Hydrazine Capital Management, LLC' (degree=8) and 'Hydrazine Capital Management LLC' (degree=5) are separate nodes sharing some connections. Entity normalization is needed before further centrality analysis.

88% of findings (160/181) have no thread assignment — cross-thread analysis understates actual actor overlap across the 6 investigation threads

Thread-tagged findings: Thread 1 (OpenAI Governance)=15, Thread 2 (Personal Financial Vehicles)=3, Thread 4 (AI Policy & Government)=1, Thread 6 (Mulherin & Family)=2. Thread-untagged: 160. The cross-thread actor analysis (which found only Sam Altman as a cross-thread actor) is therefore unreliable — most findings covering Hydrazine Capital, OpenAI governance, Helion Energy, and Tools for Humanity Corporation are not properly linked to their threads. Threads 3 (Venture Capital), 5 (Energy & Infrastructure), and 6 (Mulherin & Family) are effectively unrepresented in the thread-tagged corpus.

Carmen Beckwith serves as CFO across all three Hydrazine Capital IAPD-registered entities and manages Elfin Cove Capital LLC at the same 8595 Pelham Rd address — zero graph degree, critical coverage gap

Beckwith signed Form ADV as CFO for Hydrazine Capital GP LLC (CRD 165781, signed 11/25/2024), Hydrazine Capital IV GP LLC (CRD 325716, signed 11/19/2024), and Hydrazine Capital Management LLC (CRD 332160, signed 03/25/2026). She also manages Elfin Cove Capital LLC (California B20250301289, inc. 2025-09-16) at the same 8595 Pelham Rd address using the same CT Corporation agent. Despite being CFO of Altman's primary VC vehicle family, Beckwith has zero connections in the graph and no prior investigation leads. Elfin Cove Capital and its purpose are entirely unknown.

Michael Shetterly manages Amberley Properties LLC (Altman's -38M SF compound expansion, Jan 2025) and is connected only to Jennifer Serralta in the graph — role, background, and broader network unknown

Amberley Properties LLC (CA #202464414739, inc. 2024-10-31) purchased 855 Chestnut St + 952/954 Lombard from estate of deceased SF couple for -38M in Jan 2025, expanding Altman's Russian Hill compound to 4 contiguous properties. Michael Shetterly listed as manager, registered at 8595 Pelham Rd Greenville SC. In the graph, Shetterly has exactly one edge: to Jennifer Serralta (corporate, medium strength). No other findings mention Shetterly, no leads exist for him, no public profile found. Despite managing a -38M real estate transaction for Altman, he is effectively invisible in the investigation.

OpenAI appears as 7 distinct entity nodes in the graph (OpenAI, OpenAI Inc., OpenAI Inc, OpenAI LP, OpenAI Group PBC, OpenAI GP LLC, OpenAI Foundation) — fragmentation masks centrality of OpenAI cluster, which collectively would rank #2 after Sam Altman

Graph nodes include: OpenAI (degree 1, betweenness 0), OpenAI Inc. (degree 3, betweenness 0.032), OpenAI Inc (degree 3, betweenness 0.032), OpenAI LP (degree 2, betweenness 0.075), OpenAI Group PBC (degree 2, betweenness 0.129), OpenAI GP LLC (degree 2, betweenness 0.010), OpenAI Foundation (degree 3, betweenness 0.086), OpenAI Startup Fund I LP, OpenAI Startup Fund GP I LLC, OpenAI OpCo LLC (separate component). Combined degree would be ~23 edges, placing OpenAI cluster above Tools for Humanity (degree 8). De-duplication of OpenAI entity variants is needed before centrality analysis can accurately reflect the governance cluster's structural importance.
