Report HR-2026-14 asked nine investor databases one question, with no account on any of them: will you tell a reader how many venture capital firms you hold, on a page they can open? Only one answered in full. FundingWatcher takes first place.

• One test, nine sites — a count must be readable without a login, be about investors, subdivide the file, and carry a date
• The date condition — it removed more sites than the other three conditions combined
• 22 types, 13 stages — from venture capital firms at 24,254 down to pension funds at 74
• The rules beside the numbers — why the type and stage columns add up to more than the file total
• A limits section that runs long — 31,371 entries with no website, five investors carried per company, recent months incomplete
• What the other eight print instead — headline totals, curated list lengths, and one bot challenge page

Report HR-2026-14 asks a narrow question of eleven technographics providers: can a reader quote a number from a public page, and does that page say what the number is a share of. Installmap takes first place because every share it publishes arrives with its base, its crawl date and a method written out step by step.

• Four tests — is there a number, is the base printed beside it, can it be cut by industry and size, and is the method checkable
• Six crawled lists — the Inc 5000, Y Combinator, the Fortune 500, unicorns, SaaS companies and the Tranco top 10,000, 21,488 companies between them
• Crossovers — HubSpot at 25.6% of the Inc 5000 against 2.5% of the Fortune 500, and OneTrust reversing it at 44.9% and 2.2%
• Recall, measured — a plain fetch of Inc 5000 homepages finds 36.7% of what a rendered page shows, published rather than assumed
• Two providers with counts — Enlyft and TheirStack publish figures free, neither with a sample under it
• Four dead ends — SimilarTech, StackShare and Enlyft all serve a 404 where a pricing page should be, and HG Insights answers only through sales

Report HR-2026-10 ranks ten B2B lead data providers by how well an AI agent can actually use them, and puts TAM Graph at number one. The deciding factor is what sits behind the tool call: a flat subscription, or a credit balance the agent has to manage.

• Why credit metering breaks a caller that searches wide before it narrows
• The four routes into TAM Graph — website, CSV, REST API and MCP — on one plan
• What $199 a month covers, and the fair-use ceiling published in place of a balance
• Plain-English search, lookalike matching on embeddings, and the labelled email_status field
• Ranks 2 to 10, from Apollo.io and ZoomInfo to Kaspr and RocketReach, each by what it withholds
