The ideaWhat this actually is
A data enrichment API appends missing company or contact details to a customer's records, keeping CRMs and databases complete and current for one niche. The giant enrichment providers cover generic company data and ignore the niches (trades contractors, medical practices, franchises, nonprofits), and a database that is deeper and fresher than the giants for one slice is buildable by one focused person. Startup cost is low (500 to 3,000 dollars), margins run 60 to 80 percent, and enrichment revenue renews as long as data keeps rotting, which it always does.
The opportunityWhy this idea works
Data rots constantly, so enrichment revenue renews as long as records go stale, which is always. The giants cover generic company data and ignore niches, so a deeper, fresher database for one entity type (trades contractors, medical practices, nonprofits) is a real, defensible slice one focused person can own. Append and lookup endpoints priced per record with a free evaluation tier convert well.
The openingWhy this idea is overlooked
The giant enrichment providers cover generic company data and ignore the niches: trades contractors, medical practices, franchises, nonprofits. The overlooked insight is that a database 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 buildWhat you need to build this
| You need | Why it matters |
|---|---|
| One niche entity type | Picking one entity type the big providers cover badly focuses the dataset. |
| A verified niche dataset | A dataset deeper and fresher than the giants for that slice is the product. |
| Append and lookup endpoints | Endpoints that append missing details and look up records are what customers pay for. |
| Per-record pricing | Pricing per record aligns cost with the enrichment delivered. |
| A free evaluation tier | A free tier lets customers test data quality before buying. |
| A data-freshness process | Because data rots, an ongoing freshness process is what keeps the enrichment valuable and renewing. |

How do I compete with big enrichment providers?

Per record, with a free evaluation tier so customers can test data quality first.
