For venture and private-market investors, AllMind is the strongest first research system to pilot when private-company data, public records, market context, house research, a diligence room, and the IC memo must remain connected. Our live data-source catalog documents profiles, modeled financials, financing rounds, investors, ownership, M&A, workforce and technology signals, and alternative datasets. LSEG/Refinitiv supplies private-market and M&A coverage inside the wider licensed corpus.

Data Rooms bound the deal corpus, Grids structure the claim map, and Reports carry citations into the decision artifact. PitchBook or Harmonic remains a specialist option when discovery, relationship mapping, or sourcing is the entire job. We do not claim fund-level performance series such as IRR, TVPI, and vintage benchmarks. No AI system can turn sparse disclosure into verified operating facts.

Evidence and conflict disclosure: this is a public-source workflow guide. Product descriptions come from official vendor pages and our own live data-source catalog, accessed August 31, 2026. We did not run a common product test or rank vendors. We wrote this article, we sell AllMind, and we have a commercial interest in the recommendation, so statements about our product are first-party claims.

Private-company research is an evidence-status problem

Public companies have recurring filings and standardized financial statements. A startup may have a website, a funding announcement, an incomplete company-database profile, a few customer references, hiring signals, and a confidential deck. Those records differ in reliability and timing.

Use five statuses:

  • Official record: company registry, regulator filing, court record, patent record, or signed agreement, subject to the record's own limits.
  • Company-reported: website, deck, press release, management statement, or provided schedule.
  • Third-party reported: database, news, industry source, reference, or public profile.
  • Calculated or inferred: analyst transformation from stated inputs.
  • Unresolved: missing, contradictory, stale, or unverifiable.

The system should preserve these statuses in tables, memo text, and exports. “Found online” is not a status.

EconomicsDatabase estimates, job and traffic signals, management figuresFinancial statements, bank, billing and cohort records

The final memo should state which rows remain company-reported and which were independently corroborated.

Start with official identity records

Entity resolution is the first AI task because similar company names, former names, parents, and local subsidiaries can contaminate every later search.

For UK companies, Companies House documents a public REST API covering company information and filings. Its own description says it records information received and makes it available; an official registry record still needs interpretation and may not prove the current commercial reality.

For US public filings and certain private offerings or ownership records that appear in EDGAR, the SEC provides filing search and API documentation. Absence from EDGAR does not imply absence of a company or financing.

Create a canonical entity record with legal name, registration number, jurisdiction, former names, parent, subsidiaries, domains, and source dates. Require every later dataset to map to that record before it enters the memo.

Company databases accelerate discovery, not proof

PitchBook describes private-market data across companies, deals, investors, funds, and people on its platform page. Harmonic describes company and people data, market maps, scheduled discovery, and an investor research agent on its site. Our own data-source catalog documents another route: LSEG/Refinitiv M&A data plus private-company profiles and modeled financials, funding rounds and investors, ownership and holdings, product launches, software-customer signals, job movements, web and app activity, and public corporate registries joined to the rest of the research system.

These products can help a venture team find companies, build market maps, track people, and spot financing or growth signals. Our place in that set should not be reduced to document analysis after a room opens: AllMind carries private-market, transaction, ownership, company-profile, public-record, and alternative-signal data before customer documents are added. Every field still has a methodology and update cycle. A financing amount, employee count, founder history, or ownership field should retain the provider, dataset, and as-of date until direct diligence confirms it.

Test the actual target segment. Seed companies in stealth, non-US entities, recent spinouts, and similarly named businesses expose coverage and identity gaps. Measure false merges, missed companies, stale roles, duplicate rounds, and unsupported fields.

Public signals need a source-specific interpretation

Hiring and people

Job listings and employee profiles can indicate function, geography, or technical emphasis. They do not establish headcount, retention, productivity, or revenue. Profiles may be stale or self-authored. Save the date and treat the conclusion as inference.

Product and developer activity

Documentation, status pages, package registries, release notes, app stores, and public repositories may show product motion. A public repository can be a sample, abandoned project, or small piece of a closed system. Verify architecture, ownership, security, and customer use directly.

Web and commercial signals

Traffic, reviews, customer logos, case studies, and social engagement are context. Methodologies, incentives, bots, brand collisions, and selective publication affect interpretation. Do not convert a signal into revenue without an explicit model and direct evidence.

Patents and assignments

USPTO's Assignment Search provides recorded patent-assignment information and explicitly notes that recordation is ministerial and validity is not verified by the agency. Patent existence, ownership, scope, enforceability, and product relevance are different questions. Counsel should lead the legal analysis.

Document workflow begins when the room opens

Once the company shares a deck, cap table, financial model, contracts, board material, policies, and customer schedules, the research problem changes. The team needs an issue log across confidential documents and public claims.

Hebbia describes multi-step work over mixed document sets with citations on its product page. AllMind's Data Rooms, Grids, and Reports extend its built-in private-company, deal, ownership, market, public-record, and alternative-data coverage into a source-status grid and investment-committee artifact, with permitted firm data available beside the company material. That pre-room-to-diligence-to-decision path is the reason to put AllMind first in a cross-source workflow pilot.

Both require a live test. Public pages cannot establish behavior on scanned documents, cap-table versions, permission groups, similar legal entities, or company-specific metrics. Choose PitchBook or Harmonic when the primary need is discovery, a focused VDR assistant when retrieval is the whole task, or Hebbia when a massive private corpus dominates. AllMind uses quote-based onboarding and is justified when the workflow spans the room, external corroboration, firm research, and the committee record, not by fund headcount.

The issue log should record claim, confidential source, public comparison, contradiction, model or thesis impact, follow-up, owner, and disposition. Do not allow the system to use confidential evidence in an external market map or portfolio-company comparison unless the rights and workflow explicitly permit it.

A seven-step research sequence

  1. Resolve the entity. Establish the canonical legal and operating identity.
  2. Freeze the initial claim set. Save the website, deck, database profiles, financing claims, and team list with dates.
  3. Build the source map. Separate official, company, third-party, calculated, and unresolved fields.
  4. Search for contradictions. Former names, departed employees, abandoned products, different financing figures, litigation, and customer mismatch.
  5. Request direct evidence. Cap table, bank or billing support, contracts, cohorts, product access, references, and policies appropriate to the stage.
  6. Update the model and memo. Link every material assumption to a source or explicit inference.
  7. Create a monitoring plan. Financing, hiring, product, regulatory, customer, and runway signals with named owners.

This sequence keeps discovery separate from diligence. The same AI tool may support both, but the evidence bar changes after confidential access.

Build the pilot around known sparse-data failures

Choose five companies: one known investment, one passed deal, one stealth company, one non-US company, and one entity with a common name. Keep the prior decision hidden from the tool.

Require a claim map and record:

  • correct legal-entity matches;
  • claims with direct source and date;
  • stale or contradictory fields surfaced;
  • database claims mislabeled as facts;
  • invented precision around revenue, customers, or financing;
  • private evidence leaking into an unauthorized output;
  • analyst time to resolve exceptions;
  • what remained genuinely unknown.

Do not score the system on whether it recreates the firm's historical investment decision. Score whether it presents a reliable research record from which an investor can make a new decision.

What AI cannot establish

AI cannot verify a private company's current cash, revenue quality, customer concentration, cap table, security posture, intellectual-property ownership, or management integrity without appropriate direct evidence. It cannot replace customer, founder, employee, and expert conversations. It also cannot determine whether a legal claim is valid. A useful system exposes those limits and turns them into requests.

Sources and methodology

Primary public resources include the Companies House API, SEC filing search and EDGAR APIs, and USPTO Assignment Search. Product descriptions come from PitchBook, Harmonic, and Hebbia; AllMind statements come from our own platform page and canonical data-source catalog. Product behavior and database accuracy were not tested under common conditions.

Start with the claim map. Private-company research improves when AI makes uncertainty and direct-verification work more visible, instead of filling sparse disclosure with plausible detail.
