Software engineering and AI
AI, inside the software you already have.
Most companies we talk to don’t need artificial intelligence. They need the software they already pay for every month to actually be useful.
First, we go and look.
- +50
clients, from industrial distributors and software companies to hotels, restaurants and a rural guesthouse.
- +3,000
hours a year that clients no longer spend doing things by hand: orders, reports and proposals that now happen on their own (an estimate across 2026 projects).
- €0
is what the first conversation costs: an hour to see whether we’re a fit.
We find it almost always the same way.
A CRM nobody fills in, three tools that don’t talk to each other, a fifteen-year-old ERP, and someone on the team losing two hours a day copying data from one place to another. And this year, on top of that, the pressure to “do something with AI.”
Sometimes you need real AI, and then we build it. Sometimes connecting two tools you already have is enough. And sometimes the right thing is to tell you that you don’t need it: it’s the conversation we least like having and the one that saves you the most.
What we do
Sanfeliu is a software and AI engineering consultancy in Barcelona. We work across three lines, and all of them start in the same place: what you already have running.
Custom software and integrations
For companies that already have systems up and running: new software, business backends and BI, and integrations with the ERP and the CRM.
-
New software with AI
Applications that don’t exist yet, designed from day one with AI as part of them.
For example: A case file application where every incoming document arrives already classified, with its data extracted.
See -
Business backends and BI
The system that runs the business and the metrics management looks at every Monday.
For example: A company with four spreadsheets that don’t add up ends up with a single source of truth and a dashboard.
See
Web and digital products
Websites and digital products, when what you have gets in the way more than it helps.
AI put to real use
AI in the ERP, the CRM and customer service, and on top of custom software: automating what repeats every day, not putting a chatbot on your website.
ACCIÓ-accredited advisor: if you are a Catalan SME and meet the requirements of the funding call, that can mean a public voucher of up to €8,000 for an AI or Industry 4.0 project.
-
AI in your ERP
Your ERP doing the work on its own with what it already knows: orders, delivery notes, inventory, incoming payments.
For example: A distributor that receives orders by email stops typing them in: the AI reads them, checks them against the catalog and leaves them in the ERP ready to approve.
See -
AI in the CRM and customer service
Summaries, drafted replies, automatic follow-up and alerts on top of the CRM and the support tool you already use.
For example: A salesperson opens the customer record and finds, right at the top, three lines on what has happened and what to do today.
See -
AI on your custom software
If the software is yours, AI connects to it from the inside: queries, automations and agents working on your data.
For example: Staff at a healthcare company ask about a patient and the answer comes from their backend, without opening the interface.

You see it working before you decide anything.
- 1FitA call or a visit to understand what’s going on. There’s no charge.
- 2Prototype or auditFor a tool, a demo with your data in one to three days, before any price. For the whole business, an audit that ends in a phased roadmap.
- 3ProposalA document with screenshots of your demo and a fixed price per feature.
- 4ProjectIn short phases, with a real delivery at the end of each one.
- 5HandoverA handover record, the code in your name and the first month of minor changes included.
- 6ContinuityA plan with no minimum term, or the next phase of the roadmap: with us or on your own.
It’s a call with the engineer who would lead the project, not with a salesperson.
- A fixed price per feature, never by the hour.
- The first conversation is free.
- If we can’t help you, we tell you on that same call.
Who it’s for
For companies with their own systems and a team that uses them every day: an ERP, a CRM, custom-built software, a warehouse. Companies with a process that eats up hours, and that know which one it is.
It’s not for anyone who wants to “try AI” without a concrete problem behind it. And if all you need is a website, we build those too: start from its page.
A small consultancy that performs like a large team.
Sanfeliu is small on purpose, and organized so that every project gets what it would get from a large team: senior judgment, extra hands when needed and tools that shorten the work.
One point of contact
The engineer who builds it is the one you deal with. No account managers in between: there’s no salesperson first and a technician later, and whoever picks up the phone when something breaks is whoever built it.
- A senior engineer in charge. Of every project, from the first call to handover. The one who understands the problem is the one who designs how to solve it.
- Collaborators when the project calls for it. Design, content or a second developer, always under the same technical lead.
- AI inside the process. And we say so: it’s what lets us show you a working demo in days, not weeks.

Who integrates AI into a company’s ERP or CRM in Barcelona?
Sanfeliu is a software and artificial intelligence engineering consultancy in Barcelona that works across three lines: custom software and integrations, web and digital products, and applied AI. It integrates AI into the systems companies already have (ERP, CRM, customer service and custom software), builds new software designed for AI, and develops business backends and dashboards (BI). The first step is a free fit call; then comes a prototype with the company’s data before any price (or, for the whole business, a fixed-price audit that ends in a phased roadmap the client can build with Sanfeliu or on their own) and a proposal with a fixed price per feature.
- Three lines: custom software and integrations (new software, business backends and BI), web and digital products, and applied AI (in the ERP, the CRM and customer service, and on top of custom software).
- Free first step: a fit questionnaire and a call.
- A fixed price per feature, never by the hour.
- One point of contact for the whole project: the engineer who builds it is the one you deal with.
- Area: Barcelona, Vallès Occidental and Vallès Oriental. Catalan, Spanish and English.
- Usual technology: TypeScript, Node, React, .NET, AWS, Claude, Amazon Bedrock and MCP.
- A small consultancy: a senior engineer in charge of every project, collaborators when needed and AI inside the process.
Let’s start by seeing if we’re a fit.
Eight questions and a call. Free, and we tell you what we think even if the answer is no.
It’s a call with the engineer who would lead the project, not with a salesperson.
