No preparation. No charge. Bring your IT manager.
Your people put your IP into software. Now other people rely on it.
Pricing logic, client methods, decision models, automations and internal applications.
Once other people depend on the software, somebody must own its tests, monitoring, changes, incidents and recovery. That job often sits between the people who understand the business and the team that runs the technology estate.
Subject-matter experts decide what the software is for, what right means and which exceptions matter.
Identity, devices, networks, cloud accounts and the policies that keep the company connected.
We turn product decisions into controls, then test, monitor, change and recover the technology.
A visible, auditable condition for every system—not a promise that a capable person will remember what to do.When AI is part of the product, ordinary tests are no longer enough. Stonehold adds evaluations, model monitoring and human approval where judgement still matters.

Current documentation and a usable handover pack
Nothing appears broken: the application is online, the API responds and a quote is produced. But its 14.2% margin breaches the company's 18% policy. Here is what ordinary monitoring sees, and what Stonehold adds.
Everything appears to be working.
The output is technically valid, but the business has not authorised it.
The commercial owner confirms that quotes below 18% require approval.
Candidate releases must handle representative pricing cases correctly.
The quote is held, routed to the right person and the exception is recorded.
The work stands alone. Whatever you decide next, the map and action plan are yours.
Establish what the business relies on, what must remain true and the smallest sensible response.

“Great software was being built with AI. Nobody was set up to look after it.”
I started Stonehold so companies could keep their experts in charge of the product while giving the technology a proper, accountable operator.

No. AI made the problem more common, but continuity matters whenever important company knowledge lives in code that too few people understand.
Product purpose, policy and risk appetite stay with you. Stonehold operates the technology under explicit approvals, inside systems you control, with a current handover pack.
