Build AI products that ship — and stay shipped.
HARTLEBURY SOFTWARE LIMITED is an AI & software development agency for teams who need outcomes: secure systems, fast iteration, and reliable delivery from discovery to launch.
Discovery & decisioning
Define the value, constraints, and the fastest credible path. We leave with a plan you can execute.
Build & harden
Ship in small slices: secure by default, observable, and maintainable. No fragile demos.
Launch & evolve
Operate, measure, and iterate. We improve quality and performance as usage grows.
A pragmatic reply, not a sales sequence. If we can help, we’ll suggest a small first step with explicit scope, timeline, and decision points.
Threat-aware engineering, sensible permissions, and hardened environments—without slowing shipping.
Information architecture and UI patterns that feel inevitable—fast, accessible, and consistent.
Assistant workflows, retrieval, and evaluation—built for reliability, cost control, and governance.
Instrumentation, tracing, and practical SLO thinking so you know what’s happening—before users do.
APIs, data flows, and automation that remove friction—across legacy and modern stacks.
Pairing, reviews, and pragmatic standards so your team moves faster after we leave.
Want a delivery partner with sharp edges and zero fluff?
Bring the problem. We’ll bring a plan, an execution cadence, and engineering you can rely on.
“They translated messy requirements into a clear build plan, then delivered exactly what the business needed—without drama.”
“The quality bar was obvious: clean architecture, great defaults, and careful edge-case thinking. It shipped fast and stayed stable.”
“Our AI features were implemented responsibly—testing, monitoring, and controls were built in from the start.”
What do you build, exactly?
AI-enabled products, internal tools, APIs, data workflows, and modern web applications. The through-line is production reliability and measurable outcomes.
How do you keep AI features safe and predictable?
We design evaluation loops, guardrails, and observability. Where appropriate, we add retrieval strategies and cost controls so behavior remains stable.
Can you work with an existing codebase?
Yes. We start by mapping constraints, risks, and high-leverage fixes, then deliver improvements in small, reviewable slices.
What does a first engagement look like?
Usually a short discovery to align scope and success measures, followed by a build phase that ships in weeks—not quarters.
How do you communicate progress?
Clear weekly milestones, written updates, and demo-ready increments. We prefer decisions over status meetings.
Do you offer ongoing support?
We can transition cleanly to your team or stay engaged for iteration, maintenance, and reliability improvements.
