Voice agents
Custom phone agents that answer at any hour and resolve or route calls according to your rules.
Available for new projects
Applied AI that answers, reads and automates inside your business.
We specialise in applied artificial intelligence. We build voice and text agents, automate documents and processes, connect AI to your systems and build the software and cloud it runs on. Over eight years of production software: if your project needs it, we build it.

The full range
From idea to production, at any point along the way
AI rarely arrives on its own: it needs data, integrations, software and infrastructure to run on. We handle all of it, so we can take on a whole project or just the piece you are missing.
AI agents
They converse, decide and act.
- Voice agentsThey answer calls in a natural voice and resolve or route them according to your rules.
- Conversational agentsOn your website, in internal chat or in messaging apps, with your information and your tools.
- Process agentsThey chain steps together, query your systems and ask a person for approval when needed.
AI on your data
It reads, finds and understands.
- DocumentsInvoices, contracts and forms read, checked and recorded.
- Company knowledgeAnswers from your manuals and contracts, citing the source.
- Models on your serversOpen models deployed, optimised and measured on your own infrastructure.
- Security and controlPersonal data protection, filters, traceability and continuous evaluation.
- AI in your teamBringing AI into your technical team, with good practices and training.
Software, data and infrastructure
What makes it all work.
- Custom softwareWeb applications, internal dashboards and APIs.
- IntegrationsCRM, ERP, booking and accounting systems connected, with n8n or custom code.
- Real-time dataSensors, telemetry, alerts and dashboards.
- Cloud infrastructureAWS and Azure defined as code, with automated deployments and costs kept in check.
- Technical auditSecurity, costs and architecture, with a prioritised improvement plan.
Your case doesn't fit any of these boxes?
That's normal. We have worked in phone support, industry, energy, education, hospitality and accounting, and we get up to speed quickly with how each business works. Tell us about it and we'll tell you honestly whether we're the right fit.

Six services, one standard: it has to work in your business
Agents that talk and write, documents that process themselves, automated bookkeeping, and the software and cloud they run on.
Conversational agents
They answer from your information, cite the source and carry out tasks in your systems.
Document processing
Invoices, delivery notes and contracts read, checked and recorded without typing a thing.
Invoicing and bookkeeping
From the supplier invoice to a balanced journal entry, ready to export.
Custom development
Custom applications, integrations and data platforms, with AI where it helps.
Cloud infrastructure
AWS and Azure automated, secure and with spending monitored. Migrations planned in phases.
Sectors
Where it fits
The same services adapt to very different businesses. Some typical cases:
Hotels and tourism
Phone bookings and enquiries at any hour, supplier invoices for each property and instant answers on group terms.
Construction and real estate
Delivery notes and invoices assigned to each site, progress portals for clients and searchable technical documents.
Accounting and law firms
Invoices and receipts turned into journal entries, and quick answers about client files.
Industry and energy
Sensors, alerts and plant data in real time, with an assistant that answers questions about them.
Healthcare and regulated sectors
Voice and AI running on your own servers, with data never leaving the building.
Retail and services
Customer service, orders and integrations between the tools you already use.

Why work with us
We know AI inside out. And we know how a business works.
That combination lets us design the solution that fits your business and choose the most viable option in each case, instead of always selling the same tool.
AI, from the inside
We deploy, tune and evaluate models, not just use them. We know what each tool can do and where it fails.
Business, from the inside
Eight years in companies across very different sectors. We understand processes, costs and constraints before proposing technology.
Production engineering
Platforms with 100,000+ users, 1,000+ real-time sensors and automated deployments. What we deliver keeps working.
Direct contact
You talk directly to whoever designs and builds the solution. No hand-offs, no sales layers.
How we work
Start small, measure, then grow
Only what has proven to work gets scaled up. Before we start, you have the scope, the pilot price and an estimate of running costs in writing.
- 30 minutes
Assessment
We get to know what you want to improve and tell you honestly whether AI makes sense there.
- 2–4 weeks
Focused pilot
One real use case, a measurable goal agreed upfront and a fixed price.
- Depends on scope
Roll-out
Integration with your systems, security, testing and training for your team.
- Monthly
Ongoing support
We make sure it keeps working, measure the results and improve it based on real use.

Questions
What people usually ask us
Do you only build voice agents?
No. Voice is one of our specialties, but we build all kinds of AI solutions (text agents, documents, search over your information, self-hosted models) and whatever software, integrations and cloud are needed.
Do you use platforms like ElevenLabs or OpenAI?
When they're the best option, yes. We have evaluated them against custom development and know when they fit and when they don't: if you need more privacy, higher volume or more control, we build that piece to measure.
Do I need a technical team?
No. We handle the technical side from start to finish and explain every decision in plain language. If you do have a team, we work alongside them.
How much does it cost?
It depends on the scope. After our first conversation we propose a pilot with a fixed scope and price, with an estimate of running costs (models, telephony, servers).
Do you work with companies outside Spain?
Yes. We work remotely with companies in any country, in English or Spanish, and fit meetings around your time zone.
What happens to my data?
It stays under your control. Where needed, the systems run on your own servers and the data never leaves your network.
Tell us what you want to solve.
A 30-minute conversation is enough to know whether we can help and how. No commitment.
