Admix, an Employee-Owned Mixer Maker’s Battery Slurry

Admix, Inc. is an employee-owned mixing-equipment company based in New Hampshire, USA, founded in 1989, and also supplies dispersion solutions for battery slurries.

1. Company Overview

Company name: Admix, Inc.
Founded: 1989, by founder Lou Beaudette
Headquarters: Londonderry, New Hampshire, USA
Ownership: Employee-owned
Overseas subsidiary: Admix Europe ApS, Fredensborg, Denmark

2. History and Workforce

Founded in 1989 out of a small office in Londonderry, New Hampshire, the company introduced its early in-line static mixer, the “Admixer.” Over the following 35-plus years it grew by supplying mixing equipment to the food and beverage, cosmetics, chemical, and pharmaceutical industries, and internationalized by establishing a European subsidiary in Denmark.

The company operates under an employee-owned structure; at its 35th-anniversary announcement in 2024, CEO Mike Rizzo emphasized the significance of co-owners worldwide. Detailed organizational structure is (undisclosed).

The employee-ownership structure was formalized with the adoption of an ESOP (Employee Stock Ownership Plan) in 2000, and the company is presented as 100% employee-owned today (source: certifiedeo.com, based on U.S. Department of Labor Form 5500 filings and third-party data).

3. Core Technology and Key Equipment

The company has published case studies using its Rotosolver high-shear mixer and Fastfeed vacuum powder-induction system to address lithium-battery slurry formulation (bitumen-pitch dispersion, CNT-CMC mixing, etc.).

• Rotosolver — high-shear in-tank mixer, applied to battery-slurry pitch dispersion
• Fastfeed — vacuum powder-induction system, applied to CNT-CMC mixing
• Admixer — static in-line mixer (early-founding product)
• High-shear in-line mixers/homogenizers, laboratory and pilot mixer lineup

Per the official datasheet, the Rotosolver lineup ranges from the RS-02 (1 HP, 3,600 rpm, up to 10 gallons) to the 400RS300 (75 HP, 900 rpm, up to 10,000 gallons), all rated at 100 cP viscosity, and is designed to cut energy consumption by up to 30% while completing most batches in under 10 minutes. Cited battery-slurry applications include dispersing bitumen-based pitch into NMP (N-methyl-pyrrolidone) at 79-L and 322-L batch scales, while the Fastfeed vacuum powder-induction system is used to induct and blend carbon nanotubes (CNT) and CMC into NMP at 2.3-2.5 kg/min (source: Admix’s battery-slurry page and Rotosolver datasheet).

4. Production Infrastructure and Quality Assurance

The company operates its Londonderry, New Hampshire headquarters and its European subsidiary in Fredensborg, Denmark. Detailed production capacity is (undisclosed).

5. Track Record and Partnerships

Food and beverage, cosmetics, and pharmaceuticals are the company’s traditional core industries, and it states it has recently been expanding applications into the lithium-battery slurry field. Individual battery customer names are (undisclosed).

6. Financial Status and Roadmap

The company does not publicly disclose its own revenue figures, but third-party data provider ZoomInfo estimates annual revenue at approximately USD 14.3 million, headcount at 51-200 employees, and headquarters at 144 Harvey Rd, Londonderry, New Hampshire (third-party estimate, not an official company disclosure; confirmation needed).

As an employee-owned, privately held company, revenue and other financial figures are (undisclosed).

The company continues to expand its application into lithium-battery slurry mixing, and is releasing various new products addressing viscosities from low to high.
