The software industry's data infrastructure was built to track funding events.
Bootstrapped vertical SaaS — shop-management systems, lab compliance tools, niche field-service platforms — generates none, so the databases organized around rounds and investors never see it.
For buyers consolidating vertical software, that unfunded long tail is not a rounding error. It is the thesis.
Bootstrapped vertical SaaS lives entirely off the funding-indexed map — and it is precisely the population most worth buying. A full-web census finds it the way its customers do: by reading what the product says it does, for whom, at what price.
No round raised, no press release, no database row. Bootstrapped products are fully documented on their websites and completely unindexed in funding-centric tools.
Each product publishes its niche, pricing tiers, integration partners, and customer logos — because narrow targeting is the marketing strategy. The evidence is right on the site.
Conference lists, marketplace crawls, and referral chains each start from a partial index of the niche. They find real companies and miss unknowably many more.
100M+ classified domains across 700+ categories. The software population falls out of the classification regardless of funding history, press, or directory presence.
Two passes cut through software's noisy vocabulary. Pass one triages cheaply; pass two reads each site the way a customer and then an acquirer would.
Live product or dead domain? Actual SaaS or agency with a product page? In-scope vertical or generic tool? Disposed cheaply at scale.
Full LLM read against your written thesis. Each extraction lands as a quoted snippet with source URL. Fifteen signals, three scores.
Who the product serves, in its own words — corroborated by customer logos, testimonials, and case studies from inside the niche.
Published pricing structure (per-seat, per-location, per-transaction), trial mechanics, self-serve vs. demo-gated enterprise flows.
Integration pages, API docs, marketplace presences — the partner ecosystem that makes a vertical product sticky.
True multi-tenant SaaS vs. installed software vs. services wearing a product costume — a distinction acquirers care about intensely.
Founder visibility, team pages, hiring posture, changelog cadence — the liveness check that separates maintained products from frozen sites.
From the standing 15-signal framework; these six carry vertical-SaaS theses. Every extraction is quoted and sourced.
The load-bearing signal: which industry the product serves, evidenced from ICP language, customer walls, and case studies — not a category tag. We extract at the granularity the product itself claims, then corroborate; “software for independent pharmacies” is a thesis-relevant fact, “healthcare IT” is filing noise.
Published pricing, self-serve signup, trial mechanics, billing language — the commercial architecture is on the website and discriminates sharply. Per-seat pricing with a self-serve motion implies one kind of business; “contact sales” implies another; an invoice-shaped services page implies a third. We capture the motion as evidence because it predicts revenue quality and post-close build requirements.
Integration ecosystems are vertical SaaS's moat made visible: the accounting packages, industry hardware, and platform APIs a product connects to define its workflow position. Partner pages and API docs are read and quoted — a product woven into its vertical's stack churns and prices differently than a standalone tool.
Bootstrapped SaaS is founder-context-rich by nature — bylines on changelogs, origin stories rooted in the industry, “built by a contractor for contractors.” Captured strictly as published; combined with operating history and independence evidence, it feeds Transition Context without inferred personal circumstances.
A live product leaves footprints — dated changelog entries, release notes, blog cadence — while a zombie leaves a beautiful site frozen in 2021. For software acquirers, the distinction between maintained and abandoned is worth more than most firmographic fields combined. Captured as dated evidence, not impressions.
Consolidator branding in the footer, “family of products” pages, acquisition announcements — each zeroes the score with language quoted. Roughly one in ten keyword-perfect candidates fails on ownership; software's version is the quietly-acquired product still wearing its founder-era site years later.
Composite reflecting real run behavior. Thesis: bootstrapped SaaS serving industrial and trade businesses — shop management, field service, quoting, compliance — North American, product-led, independent.
Job-management product built by a former shop owner, self-funded eleven years, per-seat pricing published, 400 logos from one trade, founder still writing release notes. No round, no press, no database row anywhere — surfaces only from full-web coverage.
Product describes itself as “dispatch board for service contractors” — trade language, not software-category language. Keyword tools miss it entirely; the census classified it from ICP evidence on the product's own pages.
Products behind login walls with one-page marketing sites, tools whose sites cannot support classification either way — labeled honestly, never force-classified.
Agency whose “platform” page fronts a services business — classified out on delivery-model evidence, quoted.
Polished site, changelog stopped two years ago, careers page empty — activity-trajectory evidence, documented.
Footer announces membership in a software group's “family of brands” — ownership zeroed, sentence quoted.
Eleven published specimens from industrial verticals demonstrate this discipline: view the sample page.
Every sourcing method has limits; ours are stated per record so the rest of the deliverable earns trust.
ARR, churn, NRR, seat counts, margins — none are published and we do not manufacture estimates from page text.
Code quality, architecture, and the single-tenant skeletons in a “cloud” product's closet belong to technical review.
No website signal supports willingness-to-transact — we categorically refuse to sell that inference.
Enterprise motions with sparse public sites get flagged as insufficient evidence rather than guessed.
Scored CSV plus evidence appendix — served vertical, delivery model, pricing motion, ecosystem, liveness, ownership — quotes and URLs per row.
You disagree with rankings; we translate the disagreement into ICP terms and re-run the scored universe. Included, and usually the moment the thesis gets sharp.
Letters that cite the product's actual integrations and niche read as customer-level attention. Founders who ignore brokers answer those.
Annual monitoring re-reads the universe: new pricing pages, stalled changelogs, new footers announcing new owners. Vertical software moves; the map moves with it.
Custom ICP re-runs included throughout. 300+ organisations served, including a leading European telecom operator and a major airline-metasearch platform.
The claim in one sentence, varied everywhere on this site: leading company databases index the companies they found; we start from the entire active web and read it against your exact thesis, with evidence both ways.
| Question | Funding-indexed / horizontal databases | Full-web census screening |
|---|---|---|
| When does a company become visible? | When capital or press touches it | When its website exists |
| Bootstrapped niche leader, 12 years old | Usually absent | Read, classified, scored — with its pricing and ecosystem quoted |
| Product described in trade language, not software language | Miscategorized or missing | Classified from ICP evidence; the keyword-missed cohort is a standing specimen section |
| Quietly acquired product with founder-era site | Listed as independent | Ownership zero, footer language quoted |
| Services firm with a “platform” page | Listed as software | Classified out on delivery-model evidence, documented |
| Category granularity | “Software — vertical: healthcare” | The product's own ICP claim, quoted, corroborated |
| Thesis iteration | New filters on the same index | Full re-run against your revised ICP, included |
Each artisanal discovery surface is a legitimate lens — the failure is treating any of them, or all stitched together, as a census.
Surface only products that chose a platform's ecosystem. Excellent coverage of one stack's satellites; silence about everything built outside it.
Capture founders who buy booths — a marketing-budget filter, not a quality filter. The most efficient bootstrappers often skip them deliberately.
Index what users bothered to review. Over-weights horizontal tools with large seat counts; under-weights the twelve-person product running 400 machine shops with zero public reviews.
Artisanal surfaces overlap heavily — working more yields sharply diminishing discoveries as the same funded, marketed, reviewed products keep reappearing.
Census coverage does not diminish — its marginal discoveries are precisely the products no surface carried. For consolidators whose edge depends on meeting founders before the auction, that unshared cohort is the entire strategic value.
Name the vertical and the thesis. A specimen report arrives the same day; a scoped proposal for the niche follows.
