Established in 1999, this profitable, founder-led engineering and manufacturing company designs, builds, and services custom industrial controls, test and automation systems, and hazardous gas-detection safety systems for automotive OEMs, Tier-1 suppliers, national test labs, and government research programs across the Detroit automotive corridor.

Three complementary revenue lines (controls and automation engineering; custom test and automation systems; and fixed hazardous gas-detection systems) are underpinned by a recurring calibration-and-maintenance base of roughly $400,000 to $500,000 per year that renews across approximately 15 accounts. The company both engineers and manufactures its equipment in-house and owns several proprietary products (emissions canister-loading and helium leak-detection systems) that have never been actively marketed, an immediate, low-cost upside for a new owner.

Financial highlights: 2025 revenue of approximately $1.23M with adjusted owner earnings (SDE) of approximately $325K; 2026 is pacing to a record year of roughly $1.66M in revenue, on approximately 62% gross margin. No company debt.

The single most credible growth lever: the business has grown for more than 27 years almost entirely on reputation and referral, with no dedicated salesperson and effectively no marketing. A buyer who adds professional sales and marketing capability inherits deep, blue-chip relationships and a strong reputation with substantial untapped demand.

Owner-occupied real estate (two buildings, approximately 4,800 sq ft on roughly 2 acres) is available with the business or via lease-back. The company is SBA-financeable, and ownership is open to a transition period and limited seller financing.

Ideal for an engineer-operator, a strategic acquirer in industrial automation or safety systems, or a private-equity add-on. Financials, customer detail, and company identity are available to qualified buyers under a non-disclosure agreement.
