By Matt Heim — laundromat operator (ran a 10-store portfolio and an NYC pickup & delivery business)
The MatYard index tracks 59,073 candidate laundromat locations across the United States, of which 26,747 are high-confidence verified as operating laundromats. Every listing is produced by resolving records from roughly twenty distinct data sources — business directories, mapping and points-of-interest platforms, and industry data — into a single place, rather than republishing any one source.
We continuously ingest public business directories, mapping and points-of-interest platforms, and laundry-industry sources. Each source contributes observations — a name, an address, hours, a phone number — never a finished listing. Operator and ownership information is enriched separately from state business registries and public filings.
The same laundromat typically appears in many sources under slightly different names, addresses, and coordinates. Our entity-resolution engine merges records in layered passes — a shared standardized address, a single-location phone number, an exact suite, then tightly guarded name-and-locality matching — and is engineered to refuse weak-signal merges: when records at one address disagree on what business they describe, we keep them apart rather than guess. When sources disagree on a fact, the value corroborated by the most sources wins.
Every place carries a confidence grade. High means multiple distinct sources corroborate an operating laundromat at that location — only these pages are submitted for search indexing. Lower tiers (typically single-source records, which can include closed or historical listings) remain visible and clearly marked as less corroborated until further evidence arrives. Profile pages show their own source count and, where genuine observation dates exist in the source data, when the place was last observed.
The serving index is rebuilt from the underlying source graph on a daily schedule, so corrections and newly resolved places propagate to the site shortly after entering the pipeline.
