investor-behavior-dataset

Self-produced structured data from the investor_behavior_analysis research (Finalsystems, part 2 of the startup full-lifecycle decision toolchain). It profiles global investors' pre- and post-investment behavior around semiconductor (chip) startups, reconstructed from free public sources and organized into entity / event / chain / company tables.

Contents

Config	Files	Grain	Row est.
entity	investors_entity_v0.3 + investors_provenance_v0.2	1 investor per row	~1,915
events	funding / exposure / interface (clean_human v0.2, identity_patch v1)	1 event per row	funding ~1.4K / exposure ~3.3K / interface ~3.2K

Data dictionary & machine contracts

Each table ships a human-readable schema spec (*.spec.md) and, where a programmatic contract exists, a machine JSON Schema (*.schema.json) under schemas/. These are authoritative for column semantics, keys, enums and null policy.

• investors_entity_v0.3 — 1,915 investors (frozen v0.2 989-row base + 926 interface-recovery entities), 22 columns, stable IDs (wikidata:<QID> / interface_recovery:<hex>)
• chains_chip_v0.3 — one temporal chain per funding-level company outcome; schema_version v0.3.0; full Arrow schema incl. exposure/interface event ids in-window

Scope

• Universe: semiconductor / chip startups (2,278 Crunchbase seed universe) + global investors across 9 types (IB / PE / AM / HF / VC / Pension / CVC / SWF / Angel).
• Time: coverage through 2026 (static snapshot; see provenance for collection dates per source).

Data quality & limitations

• Self-produced analysis fields from public sources (SEC EDGAR, Wikidata CC0, company/investor sites, news via Tavily, AKShare, etc.).
• Contains no redistributable third-party raw rows — only aggregate / derived / self-produced fields.
• Known coverage ceilings per investor type (e.g. SWF ~50%, interface ~70% paid-source); per_vc_amount_usd ~16% populated; descriptive, not causal or predictive.
