Two companies, owned outright.

Company 01

ProofVue

A verification desk for people who buy from factories. ProofVue gathers what is knowable about a supplier, checks it against independent records, and returns a report that says whether a company makes the goods or resells them, with the evidence behind the answer kept in view.

The Long Field · Chapter Four

The Long Field

He had walked the field twice before the light came up properly, and both times the grass had told him nothing at all. The ledger said the boundary ran east of the elm. The elm had been gone for thirty years.

A field remembers being walked across, but it does not remember who did the walking. That was the whole of the difficulty, and everybody in the parish had known it long before the solicitors arrived with their folders.

By noon he had stopped looking down and started looking at the hedges instead, which is what his grandmother would have told him to do in the first place.

A third company joins next year. We will name it here when it launches.

02What we do

The companies run. We own them.

There are three jobs at this level, and none of them is making the product.

We fund them

Every company here is paid for out of our own balance sheet. Nobody has to raise, nobody has to hit a number set by someone who has never used the product, and nobody is spending money that has to be returned on a schedule.

Self-funded
No debt
No outside investors

We set the bar

We do not write the code. We decide what is good enough to carry our name: how the thing looks and reads, whether it works properly before it ships, what happens to a customer's data, and how long somebody waits for an answer.

Support

We do not sell

There is no exit plan, because there is no exit. We look at each company properly once a quarter, and we have planned for succession, so ownership outlasts the people holding it today.

03About

Owned by one house, for good.

Greydient Labs is a privately held company that owns software companies. We hold each one in full: no minority stakes, no joint ventures, no co-owner with a different idea of when to cash out. Two today, a third next year, and we would rather that number stayed small.

Most software changes hands every few years, and the people who paid for it are the ones who absorb the cost: the migration, the repricing, the features that quietly stop being maintained while everyone waits for the deal to close. We would rather own two things properly for twenty years than ten things briefly.

04Get in touch

Write to us.

One form. It reaches a person, and a person answers.

Careers

We hire rarely and slowly. Send work you are proud of instead of a cover letter. If there is nothing open we will say so, and we will keep the note.

Investors and press

We do not take outside investment, so there is nothing to pitch and nothing on offer. For press, or for anything that does not fit above, the same form reaches us.
