Our mission
Give every organization control of its intelligence.
AI is becoming the operating layer of every company. It should understand your context, work across any model, and remain fundamentally yours.
The world is shifting
All companies will run on AI.
That part is settled. AI is already changing how organizations understand information, make decisions and execute work. What is still open is how much of it stays yours: your context, your models, your workflows.
80%+
of enterprises will deploy industry-specific AI agents in support of critical business objectives by 2030.
Up from less than 10% today. Source: Gartner, AI-Enabling Cloud Services are the Future of Cloud, September 24, 2025The problem
AI is being adopted the wrong way.
Most companies implement AI the way big tech wants it implemented: rented models, per-seat licences and your data on someone else's infrastructure. That is an excellent business model for the vendor, and a poor deal for you.
Model dependency
One vendor sets your limits, your roadmap and your price.
Data leakage
Company knowledge ends up in systems you do not control.
Inefficient execution
Every task hits an expensive model, even the simple ones.
Paying for access
Per-seat licences mean only part of your team ever gets AI.
Average results
Without company context, AI returns answers anyone could get.
Unclear strategy
Pilots everywhere and no decision on what AI should own.
Any model, any time
Local, cloud or frontier. Swap whenever a better one arrives.
Data that stays home
Your cloud or your own hardware, with full residency.
Right engine per task
Routine work runs local, hard reasoning goes to the best model.
Pricing without seats
No per-user fees and no markup on tokens. Onboard everyone.
Your company context
Documents, people, systems and decisions in one memory.
One operating layer
A single place to build on, instead of scattered tools.
The solution
Implement AI the right way.
We built the opposite: your context, your models, your infrastructure, and a price that does not grow with every user or every token. The platform follows your business model instead of protecting ours.
Three foundations
Sovereignty. Understanding. Efficiency.
Three principles behind everything we build, and the reason AI turns into lasting value instead of another tool nobody owns.
Sovereignty
You stay in control.
Understanding
Turn data into intelligence.
Efficiency
Do more with less.
Why both matter
Different strengths, one team
Humans and AI are not competing. They excel at fundamentally different things. The magic happens when you put them together.
Humans excel at
-
Judgment & ethics
Making nuanced decisions that require context, empathy, and moral reasoning.
-
Creative thinking
Generating original ideas, connecting unrelated concepts, and imagining what doesn't yet exist.
-
Relationship building
Building trust, reading emotions, negotiating, and understanding complex social dynamics.
-
Strategic vision
Setting direction, defining priorities, and making high-stakes bets on an uncertain future.
AI excels at
-
Processing speed
Analyzing thousands of documents, records, and data points in seconds without fatigue.
-
Pattern recognition
Detecting anomalies, trends, and correlations across massive datasets humans would miss.
-
Tireless execution
Running tasks 24/7 in parallel across tools, systems, and time zones without errors.
-
Instant knowledge
Accessing, synthesizing, and applying vast knowledge bases on demand in real time.
Human + AI
The future belongs to super-powered humans
Small teams. Giant output.
Every employee becomes a manager of AI workers. Every team operates with the output of ten. The organizations that win won't hire more people. They'll give their people more leverage.
We build the layer where humans lead and AI executes. You set the direction, review the work, approve the actions. The technology handles everything else.
A new way of working
From prompts to a queue of meaningful work
The way we work is changing. Humans become supervisors and quality assurance. AI does the heavy lifting. Everyone becomes a manager.
Sense
Agents continuously watch signals, data and triggers across your stack.
Propose
AI proposes tasks, drafted, contextualized, ready for review.
Review
Humans decide what matters, what is slop, and what to delegate.
Execute
Agents run the work in parallel across your tools and data.
Approve
Humans approve the most critical actions before agents execute them.
The new unit of work
Domain intelligence
An agent does a task and forgets it. A domain intelligence holds one part of your business: it knows the sources, keeps the context, and keeps producing work there. So you do not roll out one assistant. You build marketing intelligence, product intelligence, business intelligence, each of them permanent and each of them yours.
One platform, not many
You can't build the future of work on disconnected tools
An organization that wants to operate with AI needs every essential capability in one place. Interconnected, governed, and shared across teams. Not five vendors, five logins, and five sources of truth.
Recordings
Capture voice in seconds to streamline what you need, when you need it.
Workflows
Build automations triggered by time, events, or any other signal.
Agents
Configure specialized agents and orchestrate multi-agent systems with sub-agents.
Memory
Persistent, shared knowledge accessible to humans and AI alike.
Tasks
Structured units of work you can review, delegate, and track. No more losing context in infinite chat threads.
Tools & connections
Connect every business app and tool, and let agents perform real actions inside them.
Data
Connect data silos, vectorize content, and let humans and agents search it all.
Chat
A natural conversational layer for humans to interact with the entire system.
Control & security
Approvals, governance, audit and stability for every action an agent takes.
Interconnected by design, and by necessity
Memory feeds tasks. Tasks invoke skills. Skills act through tools. Workflows trigger agents. Everything observed, governed and approved. That's why our platform can't be smaller than this, and why we're building it.
Control & trust
Power without control is a liability.
Real organizations need stability, security, and approvals at every step. They need the ability to compose multi-agent systems, sub-agents, and complex orchestrations, and still know exactly what happened, who approved it, and why. That's not a feature for us. It's a precondition.
Approvals
Human-in-the-loop sign-off on every sensitive action.
Auditability
Full trace of what ran, when, why, and on whose behalf.
Private deployment
Deploy in your own VPC or private cloud, so your data never leaves.
Model agnostic
Bring any LLM. Switch providers without rewriting your stack.
Why Siesta exists
We watched companies adopt AI through scattered tools, rising costs, and confusion. We believed there had to be a better operating model.
Built in Europe with privacy, control, and real business needs in mind. One platform. Not five vendors, five logins, and five sources of truth.
