ClearSphere

What ClearSphere does

ClearSphere is an Ireland-headquartered provider of integrated cleanroom and containment solutions, founded in 1989 and operating from Carrigaline, Co. Cork with a UK regional office in Elland, West Yorkshire. The company designs, manufactures, installs, and validates turnkey controlled environments for pharmaceutical, biotechnology, medical device, healthcare, electronics, nutritional, and educational clients. Its product portfolio spans four pillars: modular cleanroom systems (FM-approved walls, ceilings, doors, HVAC); containment equipment (sampling booths, dispensing suites, isolators, laminar flow hoods, safety cabinets, ducted fume cupboards); process systems (vessels, drying technology, filtration products distributed through a partnership with Waldner Process Systems); and validation/maintenance services delivered by CTCB-certified engineers.

The technology backbone is built around in-house engineering with 3D design tools, proprietary modular construction methods compliant with EN ISO 14644, cGMP, EU GMP, and FDA standards, and containment solutions capable of OEL levels below 10ug/m3. ClearSphere is the number one supplier of containment solutions in Ireland with approved supplier status at major global life science organizations.

ClearSphere generates revenue through project-based turnkey contracts combining design, construction, installation, validation, and ongoing maintenance for each cleanroom or containment deployment. Pricing is quote-based, dependent on customization, scope, and regulatory requirements. Revenue is reported at over €13 million in 2025, up from €6 million in 2020 — a roughly 17% CAGR — supported by €6M+ in growth equity from BGF in November 2025 to fund expansion into Northern Ireland and the UK. The go-to-market motion is enterprise field sales via dedicated Client Relationship Managers targeting blue-chip clients in regulated sectors.
