Cranbrook Partners & Co.

What Cranbrook Partners & Co. does

Cranbrook Partners & Co. is a privately held investment and advisory firm founded in 1991 by Zachary E. Savas, headquartered in Troy, Michigan. The firm operates two integrated business lines: an advisory practice providing strategic, operational, financial, and M&A consulting to senior management and boards, and an active ownership platform that acquires and operates controlling or significant minority stakes in middle-market industrial and operating businesses. Its current portfolio comprises Fire CATT (fire hose testing services operating in 45 states), iwerk (custom software and information systems), Roman Stone Construction Company (120-year-old precast concrete manufacturer serving NYC metro government agencies), and Ritner Steel (77-year-old AISC-certified structural steel fabricator in Central Pennsylvania).

The firm generates revenue through professional services fees on advisory engagements and through the operating performance and eventual exits of portfolio companies. It has a documented 34-year track record of more than 60 transactions valued between $3 million and $6 billion, including the 2012 sale of Snap-tite to Parker Hannifin, the 2020 sale of Vexor Technology to Chemtron, and the 2024 sale of Production Spring to Frazier Industries. Cranbrook targets private companies at inflection points — underperforming, succession-driven, or growth-constrained — with a stated concentration in automotive suppliers and industrial manufacturing, supported by case-study engagements across railroad (BNSF Railway), insurance (Nationwide), and energy (RPF Oil Company).

Cranbrook is entirely founder-controlled, with no institutional limited partners or parent entity, and distributes advisory services exclusively through direct, relationship-based outreach rather than institutional sales channels. The firm has no AI/ML product surface and does not operate as a technology company; its technology exposure is limited to iwerk's custom software development for third-party clients. Geographic operations are U.S.-centric, with portfolio reach spanning the Midwest, Mid-Atlantic, and Northeast.
