Why teams call us

Buying the tools was the easy part

Almost every engineering team now has AI licences. Very few have shared standards, guardrails, or a number that says whether any of it worked. That gap is the whole problem.

Adoption without a system

Three developers use agents brilliantly, ten use autocomplete, the rest quietly opted out. No shared context, no shared prompts, no shared standards, so the gains stay stuck with individuals instead of compounding across the team.

Agents nobody governs

Most organisations now run agents against real systems, and only a small minority have a governance model for them. Unreviewed MCP servers, over-scoped tokens and unsandboxed execution eventually become somebody's incident.

No idea if it is working

Deployment frequency looks great while review queues, rework and defect rates quietly grow. Without the right measurement you cannot tell genuine acceleration from debt you have not been billed for yet.

What we set up

The six things that turn agents into throughput

Not a strategy deck. Working configuration in your repositories, your pipelines and your tenant, delivered by people who build software this way every day.

An agent-ready codebase

Agents are only as good as the context they are given. We make your repositories legible to them, so the same request produces the same quality no matter which developer types it.

  • AGENTS.md and CLAUDE.md conventions per repository
  • Spec-driven workflow: specify, plan, tasks, implement
  • Curated context, architecture decisions and house standards
  • Test coverage where agents need a safety net

Tool selection and rollout

An in-editor assistant, a terminal agent and a cloud agent solve different problems. We help you choose per job instead of standardising on one vendor and hoping it is still the right one next quarter.

  • Evaluated on your own codebase, not on a vendor demo
  • Licence mix and real cost per seat modelled up front
  • Two-layer rollout: broad assistant plus deep agentic tooling
  • Champions, pairing sessions and an internal playbook

Agents in the pipeline

The compounding gains come when agents work while nobody is watching: on every pull request, on the test suite, and on the upgrade backlog that nobody volunteers for.

  • AI review on every pull request, tuned to your standards
  • Generated and maintained test suites
  • Background agents for migrations and dependency upgrades
  • Agent-assisted incident triage and postmortems

Governance and security

Before agents touch production systems, somebody has to own what they are allowed to reach. In most companies nobody does. We make it explicit, reviewable and enforceable.

  • MCP server registry with review and approval workflow
  • Sandboxed execution and least-privilege tokens
  • Secret scanning and static analysis on agent-authored code
  • Mapped to SOC 2, ISO 42001 and the EU AI Act

Measurement that survives scrutiny

Sooner or later somebody asks what the licences actually bought. We take the baseline before the rollout starts, so the answer is evidence instead of anecdote.

  • DORA and DX Core 4 baseline captured before the pilot
  • Adoption, acceptance and rework rates per team
  • Change failure rate watched as closely as delivery speed
  • A quarterly number you can defend to the board

Enablement that sticks

Tools do not change how people work. We train your team in the way we genuinely work, then hand the practice over, because the goal is your independence rather than our retainer.

  • Hands-on workshops on your own repositories
  • A champion per squad, supported rather than abandoned
  • An internal centre of excellence once you are big enough
  • Documented in your wiki, not ours

The agentic stack

Tool-agnostic, on purpose

This market rewrites itself every quarter. We build on open standards like MCP and AGENTS.md, so the work survives the next tool you switch to instead of being locked to whoever won this year.

How the engagement runs

One squad proving it in six weeks, not a year-long programme

The large consultancies package this as a four to five month framework exercise before anything ships. We think you should see agents working on your real code long before that.

1
Assess, 2 weeks

We map how your team actually builds today, audit the AI usage and licences you already have, and capture a measurement baseline. You get a readiness score and a ranked list of what to fix first.

2
Pilot, 4 to 6 weeks

One squad, one real codebase. Repo standards, agent workflows, AI review and guardrails go in, and we ship actual features with them. Judged against the baseline, not against a feeling.

3
Industrialise, 6 to 8 weeks

Whatever the pilot proved becomes organisation-wide: MCP registry, governance model, pipeline agents, security scanning and the internal playbook your champions will teach from.

4
Scale and hand over

Squad by squad, with your champions leading the rollout and us on call rather than in the room. We are explicitly working towards leaving.

Where to start

Three ways in

Fixed scope and fixed price, with no discovery phase that bills for six weeks before you learn anything.

Readiness review

Two weeks. We audit how your team builds, where AI has already leaked in, and what is genuinely blocking adoption.

  • Maturity assessment and readiness score
  • Tooling and licence recommendation
  • Risk and governance gap list
  • Prioritised roadmap with effort estimates

Agentic pilot

Six weeks on one squad and one real codebase, with a measured before and after rather than a demo.

  • Repo standards live in your codebase
  • AI review and test generation on real pull requests
  • Measured against a DORA and DX baseline
  • A go or no-go decision backed by data

Rollout partner

Ongoing. We industrialise what the pilot proved and take it across the organisation with your champions in front.

  • MCP registry and governance model
  • Security and compliance mapping
  • Squad-by-squad enablement
  • Quarterly measurement review

We are not consulting on something we read about

Siesta Labs builds client software with these tools every day:

  • Agents write and review code in our own pipelines, on production systems
  • We built and operate our own AI platform, Siesta AI
  • Azure-native, so governance fits the tenant you already run

FAQ

The questions every CTO asks us

No, and anyone promising that is selling you a future headcount problem. Agents absorb the mechanical work: boilerplate, tests, migrations, first-draft reviews. Judgement, architecture and knowing what is worth building stay firmly with your engineers. The teams that cut people first and adopted agents second have generally ended up rehiring.

Only if you decide it should. We can run everything under enterprise agreements with zero data retention, or entirely inside your own Azure tenant. Which model you use is decided in the assessment, in writing, before a single tool is installed.

This is the real risk and it deserves a straight answer rather than a slogan. Agents are very good at exactly the work juniors used to learn on. We design the rollout so juniors direct and review agents instead of competing with them, and we deliberately keep some work manual. It needs managing, not ignoring.

Standards committed in the repository, tests that genuinely run, AI review tuned to your rules, static analysis and secret scanning on agent-authored code, and a human approving anything that reaches production. Autonomy is a dial you set per workflow, not one switch for the whole organisation.

Almost certainly more than one. The pattern that keeps working is a broad assistant for everybody plus a deeper agentic tool for the senior engineers doing high-leverage work. We evaluate on your codebase, because vendor benchmarks rarely survive contact with a real repository.

Usually it is precisely for you. Most teams we meet have the licences, patchy adoption and no measurement at all. The licences were never the problem. The system around them is.

Curious what your team would actually gain?

Two weeks, one readiness review, and a ranked list of what to fix. Bring your messiest repository.
