Company profile

researched Aug 2026

The database's 'Sierra Holding' is not a venture-backed software startup. It is Sierra Holding Co LLC, the Delaware holding company at 11400 W. 47th Street in Minnetonka for The Sierra Company LLC, which trades as Fenix Specialty Performance Coatings/Fenix Group. The operating lineage starts with Sierra Performance Coatings in 1979, but repeated searches of company histories, regulatory records and trade sources did not identify the original individual founder; marking a current executive or private-equity manager as founder would be fabrication. Sierra built a custom-formulation and manufacturing business for coating problems not satisfied by off-the-shelf paint. It formulates urethanes, acrylic and alkyd enamels, epoxies, bake and air-dry finishes, UV-curables, polyurea, waterborne, low-VOC/low-HAPS and other systems for corrosion, heat, abrasion, chemical and weather resistance. End uses include OEM and general industrial manufacturing, structural steel, tanks, pipe and valves, agricultural/construction equipment, furniture and cabinets, drums and large containers, trucks/trailers, propane cylinders, water towers, maintenance, metal decorating/packaging, construction and concrete. Services include custom color and chemistry development, laboratory/ASTM testing, technical/application support, private-label manufacturing, toll blending, training and contractor/distributor support. NSF, FDA, HAPS-free, VOC and ISO references on brand pages are product/company claims whose exact scope must be verified per SKU, plant and certificate. Tonka Bay Equity Partners acquired/control-invested in The Sierra Company in May 2015; terms, purchase price, leverage and ownership percentage were not disclosed. Tonka Bay still lists Fenix as a current portfolio company and Shane Slominski as board chair/deal-team partner. Sierra began a buy-and-build strategy: substantially all Burke Industrial Coatings assets were acquired January 29, 2018, adding liquid-stainless-steel and antimicrobial systems; The Sierra Company rebranded to Fenix Group in late 2018 around Sierra, SureCrete Design, TK Products and Burke; Concrete Coatings Inc. was acquired February 28, 2019, adding a Layton, Utah plant, training and decorative-concrete distribution; a 2020 strategic alliance with ChemSystems broadened concrete products but was not described as an acquisition; substantially all TCI Coatings assets were acquired August 31, 2021, adding Lubbock, Texas manufacturing, OEM coatings and a South/Southwest footprint; and National Coatings joined the business May 15, 2025, adding general-industrial, packaging/metal-deco coatings, quality-planning/testing and manufacturing redundancy. The National transaction is described publicly as joining forces/the Fenix family and by transaction databases as a deal, but price, legal form and closing mechanics are not public. Current brand materials list Sierra, TCI, Burke and National in the industrial group and SureCrete, TK Products and Concrete Coatings in concrete/decorative products. The revenue model is conventional B2B chemical manufacturing: quoted product sales by gallon/drum/batch, custom formulation, contract/private-label/toll manufacturing and channel sales through distributors, applicators and contractors. Public list prices, customer contracts, revenue, gross margin, EBITDA and customer concentration are unavailable. LinkedIn labels the combined company 51-200 and displayed 53 associated profiles during review; third-party revenue estimates vary materially ($25m-$100m and narrower point estimates), so no estimated revenue is treated as fact. Manufacturing locations documented over time include Minnetonka, Minnesota; Dade City, Florida; Layton, Utah; Lubbock, Texas; and National's operations, with distribution across the U.S. and claimed international shipments. Four Sierra Holding Co LLC Form D filings are the only public capital figures: $342,000 sold from an offering beginning April 1, 2021; $1,414,273 beginning August 31, 2021; and two separate offerings beginning May 14, 2025 for exactly $8,000,000 and $19,442,875. All four filings classify the security only as 'Other,' show the entire offered amount sold, disclose no sales commissions and name six, nine, five and thirteen investors respectively. They should not be relabeled debt, equity or venture rounds without underlying instruments. The four total $29,199,148, but do not represent all capital ever invested: the 2015 Tonka Bay buyout, acquisition consideration, lender facilities and rollover equity are undisclosed. The 2021 $1.414m offering date coincides with TCI, and the 2025 offerings coincide with National, but use of proceeds is not stated; causal linkage is an inference, not a filed fact. Filings name Ray Torres as CEO in 2021 and Todd Schroeder as CEO in 2025. Peter Kirton became CEO effective March 16, 2026; Tonka Bay said Schroeder would advise the transition after roughly four years of strategic acquisitions, performance and product innovation. The current company page names Bryan Ulin CFO. SEC manager/director lists include Tonka Bay figures and historical managers, but a filing snapshot is not a reliable current-board roster. No valuation, revenue, profitability, exit process or public debt balance is available. The original database's Benchmark, Sequoia, Greenoaks, ICONIQ, Thrive Capital and AE Industrial Partners backers are unsupported and almost certainly cross-company contamination; manual searches found no primary or credible secondary connection to Sierra/Fenix. Chemical-manufacturing diligence is essential. Paints and coatings can involve flammable/combustible solvents, VOC/HAP emissions, hazardous waste, worker exposure, transport/storage, spills, fire/explosion, product-performance and environmental liabilities; waterborne/low-VOC claims do not eliminate them. Resins, pigments, solvents, additives and packaging create raw-material price/supply risk. Custom formulations and private label can concentrate technical/product-liability risk, while acquisitions create plant, SKU, ERP, EHS and quality-system integration risk. MPCA public facility data connects The Sierra Company/Sierra Corp to the Minnetonka site and lists historical contacts, but manual EPA/MPCA/litigation searches did not surface a material Fenix/Sierra-specific enforcement action, recall or filed litigation; this is a negative search result, not a clean-compliance certification. Competitive pressure comes from global coatings companies such as Sherwin-Williams, PPG, Axalta and RPM/Carboline as well as regional custom formulators and concrete brands. Fenix differentiates through smaller-batch customization, multi-brand technical breadth, application support and geographically distributed manufacturing. Its durable value thesis is cross-selling and manufacturing redundancy across acquired brands; principal unknowns are audited financials, organic versus acquired growth, Tonka Bay fund/ownership structure, leverage, customer concentration, plant utilization, EHS history, founder identity, certificates by SKU and exact transaction consideration.

Founding story

The Sierra Company began in 1979 to formulate industrial coatings for difficult applications that off-the-shelf products could not solve. Public histories do not name the individual founder, so founder attribution remains unresolved.

Business model

Private-equity-backed B2B specialty chemical manufacturer using a multi-brand buy-and-build platform; sells formulated coatings and concrete systems and provides custom development, technical service, private-label and toll-manufacturing capabilities.

Quoted product sales by volume/batch through direct OEM accounts and distributor/applicator channels, plus custom formulation, private-label and toll-blending/manufacturing revenue. No public rate card or financial statements.

Traction

Operating lineage since 1979; four brands at the 2018 rebrand, six after TCI in 2021 and seven after National in 2025. LinkedIn displayed 53 associated profiles and a 51-200 range. Revenue, volume, growth, margins and named-customer concentration are not disclosed.

Latest developments

National Coatings joined Fenix in May 2025, widening general-industrial and packaging/metal-deco capacity. Peter Kirton became CEO on March 16, 2026, succeeding Todd Schroeder, who remained an adviser during transition; Bryan Ulin is the current CFO listed by the company.

Full profile — market position, technology, go-to-market, geography, history, ownership, risks & controversies

Market position

Lower-middle-market specialty coatings platform rather than a venture startup; small relative to global coatings majors but broader than a single-plant formulator after seven-brand consolidation.

Customized solutions for coating problems that large off-the-shelf suppliers may not serve, deep application support, broad industrial-plus-concrete chemistry portfolio and multi-plant redundancy/geographic coverage built through acquisitions.

Technology

Coatings formulation chemistry, color matching, laboratory and ASTM/customer-standard testing, batch manufacturing and quality systems across urethane, acrylic, alkyd, epoxy, polyurea, waterborne, UV-curable, low-VOC/low-HAPS and specialized stainless-flake/antimicrobial systems.

Go-to-market

Direct technical sales for engineered/custom formulations, regional account support from multiple plants, product brands and distributor/contractor channels, application training and cross-selling among acquired industrial and concrete brands.

OEMs, industrial manufacturers, structural-steel and container fabricators, infrastructure/maintenance operators, construction-products distributors, concrete contractors/applicators, private-label brands and packaging/metal-deco manufacturers.

General industrial and OEM; tanks/pipe/valves; agricultural and construction equipment; trucks/trailers and large containers; metal decorating/packaging; infrastructure and MRO; commercial/residential concrete; decorative concrete; private label and toll blending.

Geography

Headquarters/manufacturing in Minnetonka, Minnesota, with documented operations or brand plants in Dade City, Florida; Layton, Utah; Lubbock, Texas; and National Coatings' footprint. Products are distributed nationally with some company-claimed international shipment.

History

Sierra operating lineage founded 1979; Tonka Bay control investment May 2015; Burke assets acquired Jan 2018; rebranded Fenix late 2018; Concrete Coatings acquired Feb 2019; ChemSystems alliance Jun 2020; TCI assets acquired Aug 2021; National Coatings joined May 2025; Peter Kirton succeeded Todd Schroeder as CEO Mar 2026.

Ownership

Controlled/private-equity-backed by Tonka Bay Equity Partners, which still lists Fenix as a current portfolio company and Shane Slominski as board chair/deal partner. Management/employee rollover, lender and exact sponsor stakes are undisclosed.

Risks & controversies

Chemical manufacturing carries VOC/HAP emissions, hazardous-waste, worker exposure, transport/storage, spill and fire/explosion risk; product failures can create corrosion, contamination, infrastructure and warranty liability. Raw-material prices and availability affect margins. Multi-brand acquisitions create quality, EHS, systems, culture and customer-retention integration risk. Certifications and environmental claims require SKU/plant verification. Private ownership leaves leverage, financial performance and related-party economics opaque. No material company-specific enforcement, recall or litigation was found in manual searches, but absence from search is not compliance assurance. The original database's six startup investors were unsupported cross-company contamination.
