Caleb Brett Eesti

What Caleb Brett Eesti does

Caleb Brett Eesti OÜ is an Estonian private company founded in 1998 and headquartered in Tallinn that provides accredited industrial services to oil, energy, terminal and logistics operators in Estonia. Its core technical offering is calibration of tankers, tanks and pipelines under EAK accreditation certificate No. K028, a regulated measurement activity that requires formal accreditation and is typically mandated for custody-transfer and inventory verification in the oil and chemicals value chain.

Beyond calibration, the company extends into adjacent industrial services: industrial insulation and the design, installation and maintenance of ventilation systems. These lines share the same customer base of large industrial asset owners and reuse the company's site-access and engineering credentials. The public customer set includes Alexela, VKG, Neste, Vesta Terminal, Ciest Logistics, Olerex, Ferm and Nord, indicating a B2B project and service-contract model focused on a small number of enterprise accounts operating critical energy and logistics infrastructure in the Baltic region.

The company operates with a small team (1-10 employees) and a single-country footprint in Estonia. There is no evidence of external funding, M&A activity, product launches, leadership changes or geographic expansion in the available data. Its revenue mechanics are project- and service-based, with pricing tied to accredited measurement deliverables, insulation scope and engineered ventilation work, rather than any software, subscription or platform model.
