ATSI

What ATSI does

ATSI Inc. is a private, full-service engineering and consulting firm founded in 1977 and headquartered in Amherst, New York (per its own website and contact details). The firm delivers multi-discipline engineering services — Front End Engineering Design (FEED) with FEL-1 through FEL-3 phases, EPCM, Owner's Technical Representative, and Existing Facility Services — across mechanical, electrical, process, structural, controls, piping, and process safety disciplines. It primarily serves enterprise industrial operators in petrochemical, energy (oil & gas and power), mining & metals, food & beverage, pulp & paper, water treatment, and (more recently) renewable energy sectors, using industry-standard tools (ASPEN, ETAP, ANSYS, Caesar II, AutoCAD, SolidWorks).

Beyond core consulting, ATSI owns three exclusive proprietary product businesses that diversify its revenue model: Algorithmica (machine-learning process control software claimed to deliver 3–7% operational value uplift and 50% maintenance cost improvement by ingesting 100,000s of unit variables per plant), Bayotech (modular on-site hydrogen production skids marketed as 25% more efficient and 40% lower-emission than legacy plants, offered via purchase or lease), and TerraHydroChem (proprietary biodegradable-solvent environmental remediation including tank cleaning and PFAS destruction).

The firm monetizes through project-based professional services fees for FEED/EPCM work and through product/equipment sales or licensing for its three exclusive offerings. Go-to-market is sales-led and direct: ATSI positions itself as an extension of the client's team, engaging through [email protected], phone, and a website contact form, and acting as either prime contractor or Owner's Technical Representative. Revenue is not publicly disclosed, there are no funding rounds on record, and the company appears to be independently/founder-owned with no disclosed parent or institutional backing.

Revenue model

1. Engineering Consulting Services: ATSI generates revenue through professional engineering consulting services, including feasibility studies, FEED (Front End Engineering Design), detailed engineering, and EPCM (Engineering, Procurement, Construction and Management) services. Projects are delivered on-time and on-budget with fees typically structured as project-based engagements.
2. Exclusive Value-Added Products: Revenue from proprietary products including TerraHydroChem tank cleaning services, Bayotech modular hydrogen production systems (with both equipment purchase and leasing options), and Algorithmica AI process control software. Bayotech offers flexible cost options with equipment purchase and leasing available.

Core offering

ATSI is a full-service engineering and consultancy firm providing multi-discipline engineering services across the project lifecycle — from feasibility studies and Front End Engineering Design (FEED) through EPCM (Engineering, Procurement, Construction, and Management) and existing facility support — for industrial clients in petrochemical, energy, mining, food and beverage, and related sectors. The firm complements its consulting practice with exclusive proprietary products: TerraHydroChem environmental restoration chemistry, Bayotech modular on-site hydrogen production skids, and Algorithmica AI/ML process control software.

Product overview

ATSI is an engineering consulting firm (operating since 1977) that provides complex engineering solutions across multiple service lines. The core offerings include Front End Engineering & Design (FEED) with FEL-1 through FEL-3 phases, EPCM (Engineering, Procurement, Construction, and Management), Owner's Technical Representative services, and Existing Facility Services for optimization, maintenance, and expansion. These are supported by discipline-specific engineering services in mechanical, electrical, process, structural, controls, piping, and process safety management. ATSI also offers three exclusive value-added products: TerraHydroChem (environmental restoration/biodegradable solvents), Bayotech (modular on-site hydrogen production skids), and algorithmica (AI/Machine Learning process control software). The portfolio operates as a unified engineering services platform with exclusive proprietary products integrated into client projects.
