Agent systems
Multi-step agents wired into the systems a business already runs — with the evaluation harness, guardrails and fallbacks that decide whether they can be trusted without a human watching each call.
AI systems that survive production.
Yellow Bloom is an AI software practice. We design, build and operate the systems companies actually run on — agents wired into real processes, the automation underneath them, and the security and governance that make them safe to leave running.
What we build and run
Process automation
Finance, operations and back office. The unglamorous half of the work, and usually the half that pays for everything else in the first year.
Security
The exposure that arrives with the models: prompt injection, data leaving through a model call, third-party model risk, and access control for software that now takes actions on its own.
Management systems
Internal platforms, reporting and decision tooling. Numbers defined once and used everywhere, so the operation argues about the decision rather than about whose figure is right.
Marketing systems
Content, campaign and CRM automation built as infrastructure rather than as a sequence of one-off campaigns that leave nothing behind.
Platform & infrastructure
The layer underneath: model routing, observability, cost control, and the regression testing that tells you a system has quietly got worse before a customer does.
Production, not pilots
Assessment
A written read of where AI changes the economics and where it does not, what it would cost, and what has to be true first. Fixed fee. Sometimes it concludes that you should not spend the money yet.
Build
Fixed scope, delivered end to end, with your own engineers in the room from the first week. Ends with something running, documented, and owned by a named person inside your business.
Operate
Running and improving what has been built against an agreed standard — until your team takes it over entirely, which is the intended ending.
What ships with every system
Evaluation
A test set and a scoring harness, so "it seems better" can be replaced with a number that moves.
Audit trail
Every consequential action logged with its inputs, its model version and its cost — reconstructable months later.
Guardrails
Explicit limits on what a system may do unattended, and a defined path for the cases it must hand back to a person.
Cost control
Per-feature spend visible from the first week, with ceilings, because inference cost is a running cost and behaves like one.
Documentation
Written to the traceability standard enterprise buyers and auditors now ask for, and to the standard your own team needs to take it over.
Named owner
One person inside your business who understands the system well enough to change it. If there isn't one, we haven't finished.
How the work is bought
Assessment
A written assessment of a defined area of the business, delivered as a document you keep and can act on with anyone.
Fixed fee
Build
One system, designed and delivered to production, with handover built into the schedule rather than bolted on at the end.
Fixed scope
Operate
Ongoing operation and improvement under an agreed standard, with a defined exit to your own team.
