About VAIR LTD, build infrastructure and CI tooling The company, its register entry, and its name.
VAIR LTD is a London software company working on build infrastructure. This page states what the company does, sets out its register entry in full, and explains how to tell it apart from the other businesses trading on the same four letters.
01 / Position
What the company does
Two activities, and no third one hiding behind a vague word.
VAIR LTD works on build infrastructure: the caching, scheduling and reproducibility layer that sits between a repository and its CI runners. That layer is where most of the time a development team loses to CI actually goes, and it is unusually resistant to being fixed by adding machines.
The company does two things. It develops its own build tooling, and it takes a small number of engagements on other teams' build systems, which is where that tooling meets pipelines nobody here wrote and assumptions nobody here made.
The scope register, the configuration format and the reference architecture are set out on the datasheet. Each carries the date and the revision letter it was written under, so a statement can be pinned to a version.

04 / Name
The word, and the businesses it is not
Vair is the heraldic term for the pattern of alternating bell shapes that represents squirrel fur in a coat of arms, and it is the French word for the fur itself. The mark used on this site is a pair of those bells, tessellated. It is a legitimate, non-derivative device, and it is the reason the company is called what it is called.
"Vair" is also a crowded stem. Several unrelated businesses use it. To save anyone the search: VAIR LTD is not connected with any of the following, and does not operate in their sectors.
- Vair IT Technologies Pvt Ltd (vairit.com), an Indian web and software development agency.
- VAIRKKO (vairkko.com), a United States workforce and training management platform.
- The Vair Companies, Inc. (vaircompanies.com), financial modelling training and advisory.
- VAIR Networks (vairnetworks.com), a managed technology provider.
- Vair Corporation, a United States manufacturing business.
- vairified.com, energy-performance inspection and certified raters.
Where this site needs to be unambiguous it uses the compound: vairworks, or VAIR LTD with the company number attached. In legal contexts the registered name is used and nothing else.
