Leadership

No executive publicly disclosed by the company or reputable press that we could verify. NYC's public DOB/DOS records don't include company officers or ownership at all, so we only show a name here when the company's own site or a named press source discloses one directly — most small subcontractors don't publish one anywhere findable. See Official Record Lookups below to search yourself.

About This List

From DOB's own owner-of-record field on each notable job's filing, above — ranked by how many of Intersystems Corporation's own projects that owner appears on. A real, sourced client relationship, not an inferred one.

Other Contractors on the Same Projects(2)
About This List

Other real companies that pulled a permit on one of Intersystems Corporation's own DOB job numbers, above — a genuine, sourced co-occurrence (same job application on file at DOB), not a confirmed formal GC/subcontractor relationship, which NYC's public permit data doesn't record at all.

NYC Contract Awards Won

About This Match

Cross-referenced against the city's own "Recent Contract Awards" dataset by vendor name — a DOB permit-pulling contractor and a procurement-awarded vendor are two different city record systems, joined here by an exact match after normalizing punctuation, legal suffixes, and common abbreviations. A real business can legitimately win contracts under a slightly different legal name than the one on its DOB permits, so an empty result here doesn't mean Intersystems Corporation has never won a city contract — only that no exact name match was found.

Public Safety & Compliance Records(45)
About These Records

These are citywide building-equipment compliance filings (including elevator and boiler safety compliance), ECB violations, and DOB complaints recorded at the same addresses as this company's projects above — not violations or complaints attributed to or caused by Intersystems Corporation. NYC's public data does not link any of these records to specific contractors (ECB violations in particular are almost always filed against the property owner), so no company safety score is shown or implied.

Stop Work Orders(0)
About These Records

DOB Stop Work Orders issued at this company's project addresses. A minority reference a job number in their text — when that job number matches one of Intersystems Corporation's own permits, it's marked directly linked below. The rest are address-level only (same building, different or unspecified job) and are shown as context, not attributed to this company.

No Stop Work Orders on record at these addresses.

Layoff & Closure Notices (WARN)(0)
About These Records

Matched by business name against NYS DOL's official WARN Dashboard (layoffs/closures affecting 50+ employees). This is an approximate name match, not verified — WARN notices are filed under whatever legal entity operated the site, which can be a parent company, subsidiary, or DBA different from the name on a DOB permit. Confirm at the source link below before treating a match as confirmed. As of 2026-08-04, no NYC-area construction company appeared on the current WARN list — an empty result here is the norm, not a bug.

No matching WARN notices on file for this business name.
