Best for: Data-obsessed builders who enjoy sourcing and verifying records
The opening
Why this idea is overlooked
The giant enrichment providers cover generic company data and ignore the niches: trades contractors, medical practices, franchises, nonprofits; a database that is deeper and fresher than the giants for one slice is buildable by one focused person, and enrichment revenue renews as long as data keeps rotting, which it always does.
The roadmap
How to start, step by step
- 1
Pick a niche the giants serve badly
Generic company enrichment is a solved, crowded market. Enrichment for one entity type (independent pharmacies, HVAC contractors, youth sports clubs) where you can be measurably deeper and fresher is where a small player wins.
- 2
Validate with five buyer conversations
Talk to sales ops, marketing, and product people who target your niche. Ask what fields they are missing, how stale their data is, and what a verified record is worth. Enrichment pricing runs on that answer.
- 3
Build the dataset with legal care
Source from public filings, licensing bodies, and permitted data partners, and learn the privacy rules that apply (consumer privacy laws treat personal contact data very differently from business firmographics). Document the provenance of every field; buyers and regulators both ask.
- 4
Ship match-and-append endpoints first
One endpoint that takes a name or domain and returns your verified fields, with match-confidence scores. AI tools help with entity matching and dedup, which is the genuinely hard part; measure and publish your match rates honestly.
- 5
Price per record with a free evaluation tier
Common models are per-enrichment pricing (fractions of a cent to a few cents per record by depth) or monthly tiers with record allowances. A free tier of a few hundred lookups lets buyers test match quality, which is how enrichment is bought.
- 6
Prove freshness on a schedule
Re-verification pipelines, a published data-refresh cadence, and changelogs are the retention engine. Stale enrichment gets cancelled; visibly fresh data renews for years, and reliability and uptime commitments come with the first paid contract.
