Vesster

The competence center for enterprise agentification

We build, run, and govern your AI agents. You own them.

Vesster is the competence center that agentifies the regulated enterprise: we build the agents, run them under governance, and hand you the keys.

The competence center for enterprise agentification

Agentification is four disciplines, not one project.

01

We build & run

Forward-deployed teams design the agents on your real processes and operate them in production, and you own the outcome.

02

We govern

VessterOS: graduated autonomy, evals as the trust threshold, audit trails and drift monitoring, built for agents, not IT change-control bent to fit.

03

We tailor the stack

Provider-agnostic, deploy-anywhere, routed to your regulatory regime. Off-the-shelf never passes review; yours will.

04

We enable your people

Capability transfer, so your teams direct and evolve the agents after we hand over.

02 / 12The promise

More than a prompt

Everyone's building agents. Scaling them across a regulated enterprise takes more than a prompt.

  • A complete agent OS

    VessterOS deploys and governs teams of agents in production, not one script running on a laptop.

  • Enterprise & regulated

    Built for high-stakes work where a demo can't go, and getting it wrong is illegal.

  • Your expertise, too

    We grow your internal capability along the way, so your own teams run and evolve it.

You own the operating system, the agents and the expertise, exit-ready by contract.

03 / 12The chasm

Why this is hard, the case for a competence center

There's a chasm between a laptop automation and a production agent.

Challenge

Anyone can run an automation on their machine; making it an agent the organization runs demands governance, security and continuous evolution.

Why it matters

Agents are probabilistic and drift with every model update, retrofitting traditional IT change-control onto them doesn't work.

How we resolve it

VessterOS, governance built for agents: graduated autonomy, evals as the trust threshold, drift monitoring, audit trails, compliance-as-executable-policy, plus a continuous-optimization team.

Challenge

Your context lives across people, processes and systems; most organizations never built the interoperability layer agents need.

Why it matters

Without it, agents can't fit your reality, safely, with the right identity and data boundaries.

How we resolve it

Forward-deployed teams build that layer on your real processes: agent-ready context, non-human identities with least privilege, typed tool capabilities, and taint boundaries so untrusted data never becomes executable privilege.

Challenge

Which models you can use, where they run, and how data flows are decided by your regulatory regime and your own security homologation, not a vendor default.

Why it matters

A bank under DORA and data-residency rules needs a fundamentally different deployment than a hospital; off-the-shelf never passes review.

How we resolve it

Deployment tailored to your reality, provider-agnostic (Anthropic / Mistral / open-source on your GPUs), deploy-anywhere (VPC / on-prem / air-gapped), data-sovereignty-routed. Your data never leaves your walls.

The pilot graveyard

05 / 12The moat

Why the regulated buyer trusts us

Proven where getting it wrong is illegal, then applied enterprise-wide.

What lets you move fast is knowing it's safe. Graduated autonomy, executable compliance and end-to-end audit trails let your risk committee say yes sooner. That operating system, VessterOS, is what makes the acceleration real.

Not only bespoke, proprietary IP

Six agents we already built, running in banking today.

Beyond bespoke engagements, Vesster brings a production-hardened agent platform: six proprietary agents that run a regulated process end to end. You get building blocks proven where getting it wrong is illegal, not a blank page.

07 / 12Deploy anywhere

Provider-agnostic · deploy-anywhere

Own your AI.

Three deployment models, one governed operating system. Sensitive workloads stay behind your walls; where you scale in the cloud, we run cloud-native on Google Cloud, our named primary hyperscaler, and stay portable to the rest.

Your regulatory regime decides where models run and how data flows, not a vendor default. We deploy to yours.

On-Premises

Your hardware, your walls.

Open-weight models on your own GPUs, air-gap capable. Nothing leaves your data center, the strictest data-residency and sovereignty posture.

  • Air-gapped capable
  • Open weights on your GPUs
  • Full data sovereignty

Hybrid

Sensitive on-prem, scale in the cloud.

Keep regulated data and workloads on-prem; burst to frontier models over private connectivity. Each workload runs where its rules allow, data-residency-routed.

  • Data-residency routed
  • Private connectivity
  • Best-fit per workload
Primary hyperscaler

Cloud

Cloud-native on Google Cloud.

We build cloud-native on Google Cloud, Vertex AI, GKE and confidential computing, as our primary hyperscaler. Portable to Azure and AWS when your estate requires it.

The best tools. None to lock you in.

We run frontier and open-source models across any cloud, or entirely on your own hardware. You get the best tool for each job, and you're never tied to a single vendor.
