Business value almost never appears on launch day. It appears in month four, when adoption is real, the edge cases are handled and the model has been tuned against actual behaviour. That is precisely when most partners have already left.

Contractual first response on critical issues
Clients who continue with us after project one
A demand forecasting model went live performing beautifully. Six months later its recommendations had quietly become unreliable. Nothing broke, no alert fired, no ticket was raised. Consumer behaviour had shifted, two competitors had changed pricing, and a supplier had altered lead times. The model was answering last spring's question with great confidence.
This is why we treat support as an ongoing engineering discipline rather than a helpdesk. Model drift monitoring, retraining schedules, evaluation suites and monthly value reporting are part of the service — because an AI system is a perishable asset in a way that a database table is not.
The same applies to conventional software: usage patterns move, volumes grow, integrations change beneath you. Value decays unless somebody is responsible for maintaining it. We would rather that somebody be contractually us.
Every other vendor's involvement ended at launch. Golden's monthly value report is the reason our programme still has funding.
Coverage can be arranged for systems we built and for systems we inherited from someone else.
Tiered support with contractual response and resolution targets, root-cause analysis on recurring issues and a visible fix backlog.
On-call, incident command, SLO management, capacity planning and the post-incident work that stops the same outage recurring.
Drift detection, retraining, evaluation regression, prompt and policy versioning, and cost-per-decision monitoring for live AI systems.
Freshness and volume monitoring, failure recovery, schema-change handling and cost management for the pipelines your reporting depends on.
Patching, vulnerability management, dependency updates, access review and audit evidence maintained continuously rather than before inspections.
A funded monthly allocation for enhancement, prioritised against the value model so improvement follows business return rather than the loudest request.

Each of these is written into the engagement as a number with an owner, a baseline and a review date.
Systems degrade quietly: models drift, integrations rot, usage patterns move. Active ownership is the difference between a business case that holds for years and one that quietly expires.
Practised on-call, real observability and blameless post-incident review compress both frequency and duration of outages — which for transactional clients is directly monetisable.
A funded monthly improvement allocation, prioritised against value, produces more return over two years than most clients' original build did, because it is aimed at evidence rather than assumptions.
Measured against the baseline agreed with the client before the engagement started.
Contractual, across all support tiers

First year under our SRE practice
A support assessment reviews your live systems, identifies the decay risks and proposes coverage matched to what an outage or a drifting model would actually cost you.
