Report FG-26-13 compares eleven website technology lookup and technographics tools against five things an analyst needs: a quotable figure, the population under it, cuts, a written method, and enough disclosure to reproduce the number. Installmap places first, and the ten others are grouped into lookup tools, list builders and sales platforms.

• Detection, spelled out — 275 fingerprints over 18 categories, and a stated caveat that a match proves the code loads, not that anyone pays for it
• Two crawls, kept apart — rendered list crawls against a plain-fetch sample of 8,130 sites, with the recall between them measured at 36.7% and 45.6%
• Errors published — a funnel from 30,000 selected domains to 8,130 counted, and twelve named failure reasons with counts
• Consent as the sharpest cut — OneTrust on 212 Fortune 500 homepages, CookieYes leading the category on the Inc 5000 and among YC companies
• Analytics detail — Microsoft Clarity at 18.8% of the Inc 5000, and a retired Universal Analytics tag still on 13.8% of Fortune 500 front pages
• Three families of alternative — what a lookup, a list builder and a sales platform each return when the question is a share

FG-26-12 compares seven startup funding data sources on a question an analyst cannot dodge: can you show where the number came from? FundingWatcher places first, because it publishes its counts, its counting rules and its own stated limits on pages that need no account.

• Four tests — readable without an account, counting rules stated, limits named, findings checkable
• The footnote test — everything needed to source a figure sits on one open method page
• What the file will not tell you — no fund sizes, no deal terms, no valuations, no round-by-round history
• 219,289 team members — matched by website domain, with 31,371 entries holding no website and therefore no team count
• An unexpected top five — accelerators and public programmes, not funds, in the most active table
• Coverage without method — the largest headline numbers in the set come with no statement of how they were counted

Fentner Group report FG-26-10 ranks ten B2B contact data vendors on a single procurement question: what a fixed monthly payment actually gets you. This episode walks through the first place finish and the nine vendors behind it.

• What a credit costs at Datanyze, Findymail, FullEnrich, Dropcontact and Clay's published rates
• Why per-seat "unlimited" at Wiza and SalesIntel is not the same offer
• TAM Graph's four access routes on one plan: website, CSV, REST API, MCP server
• The plain-English agent search, the dataset breakdown, and the per-row email provenance field
• Where the flat rate stops: half a million records a day, five requests a second

Fentner Group report FG-26-10 sets six criteria, then reads the public pages of three Reddit marketing products against them. This episode covers where the money changes hands in each model, who supplies the Reddit account and the hours, and how a bill behaves in a week when nothing gets posted.

• $5.00 per live comment, no subscription and no seats, against two products sold by the month
• A free first run from a website address, plus $10 in credits when a card is added
• The approval gate, and a person posting by hand from an established account
• Refund of $5.00 when a comment is removed, checked a day after posting
• Six comments a day priced out, and the tiers GummySearch listed before it closed on 30 November 2025

Fentner Group report FG-26-08 sets five criteria, then reads the public sites of three exhibitor-data vendors against them. The episode walks the scorecard show by show: who states the size of their file, who lets you read rows before you pay, and how the bill behaves when a buyer looks at thirty events instead of eight.

• Standing access to one dataset, versus a list bought per show, versus a file built to order
• Published dimensions: 2,603 editions, 261,164 records, 199,073 companies, 129,132 resolved websites
• Anonymous ten-row preview on every event page, against a single vendor-chosen sample or five records by request
• Fields nobody else publishes: a provenance marker on each row, and the sponsorship tier
• Refund terms, metering and cross-event lookup compared side by side

Fentner Group report FG-26-02 examines what changes once a search product returns one synthesised response instead of a ranked list. The episode separates being read by the system from being named in its output, and traces how shortlists get assembled ahead of the buyer.

• Retrieval and selection as two separate contests
• Four traits of claims that survive synthesis: attributable, bounded, corroborated, stable
• Category placement deciding entry before any product comparison occurs
• Independent description outweighing a company's own pages
• Measuring with repeated category questions, and why one observation tells you nothing

Fentner Group report FG-26-01 treats schema markup, product feeds and API metadata as an outside-in read on how well a firm governs its own catalogue. The episode sets out what those public artefacts expose about internal data quality, and where the reading stops being useful.

• Three observable dimensions: coverage, specificity, consistency
• Why gaps cluster around acquisitions, old templates and separately run product lines
• Validator-passing markup versus markup that constrains how outsiders describe the entity
• Platforms deriving their own product records when nothing explicit is supplied
• Limits: nothing about revenue or share, and silent decay after a template change
