Your company's software
Three ways I take care of your software
For companies whose business depends on software. One person responsible, from start to finish.
Modernise
Old software your business hangs on: the developer is gone, an outdated PHP or framework version, security holes. I bring it to current technology without interrupting your operations.
A training platform I built in 2012 still runs on our servers today; now I am moving it to current technology.
Build in AI
An integration project with your own data: mail, invoices, bank, programs. Every client gets their own instance, and nothing goes out without your approval.
I use it myself every day: my own assistant works in my mail, my invoices and my bank.
How my own assistant works
- ✓Sorts what comes in and tells you what needs an answer
- ✓Drafts replies in your style, you send them
- ✓Writes new emails from what you dictate
- ✓Finds what you need in old emails
Invoices and money
- ✓Records incoming invoices as expenses
- ✓Reconciles your bank transactions
- ✓Flags unpaid invoices and prepares the reminder
- ✓Collects the quarter's receipts for your accountant
Day to day
- ✓Appointments and reminders in your calendar
- ✓Tasks that repeat every week or month
- ✓Changes to your website, requested by chat
- ✓From your phone too, by voice
Accounting and tax decisions stay with your accountant.
Run it
I keep it running on our servers: updates, backups, monitoring and one point of contact, for years.

What I've built for clients
Six examples, across very different industries. Click one to read what it does.
Real clients, real words
“What I value most in these nearly 20 years with Martin isn't just the technical support: it's knowing he always responds with professionalism and warmth. Thank you for being a fundamental part of the legacy I'm leaving to my village.”
Translated from Español
“I've been on the platform for 9 years, and the few times I had a problem, it was solved within 24 hours. The meaningful part is that Martin himself is the one who solves it: he doesn't delegate.”
Translated from Español
“We've been working with Martin for years. Our platforms filt3rs.net and facad3s.net are hosted on his server, which gives us complete peace of mind, our students use both daily.”
Translated from Español
“My website was born on Palimpalem in 2008, and for all these years the platform has offered stability, simplicity and exceptional care. For me it has always been a safe space to build my presence as a writer.”
Translated from Español
“I'm extremely satisfied with Martin's service and IT work. What stands out is his deep technical expertise and his structured, goal-oriented approach. I recommend him without reservation.”
Translated from Deutsch
“I've trusted Palimpalem with my website for years. Easy-to-use platform, and Martin is always willing to help you solve any problem or doubt.”
Translated from Español
“I've been trusting this company for many years and can honestly say: having Martin and his team on your side is a real peace of mind. Professional, close, attentive and always on top of our needs. 100% recommendable.”
Translated from Español
“Great service, and small issues get solved right away. I have 5 websites on Palimpalem and I'm very satisfied.”
Translated from Español
“Working with Martin is easy and efficient. He adapts his services to every client's needs and situation. His support is exceptional and response times are fast when something comes up. Ideal if you're looking for a reliable, no-hassle service.”
Translated from Español
“It's great to see Palimpalem making the leap into modernity. The focus on mobile navigation is the biggest win, and today's visual clarity makes managing a site much easier. What used to be a memory is now a real alternative to modern builders.”
Translated from Español
“After years of working with Martin, my experience is consistently positive. He handles projects personally, listens, and gives everything to build the website you want, adapt the server, design a functional online shop. As technology and AI advance, he keeps up: that's what an inventive mind does.”

Alongside client work, I develop and operate my own products. They are the clearest proof that I deliver: from the first idea to a service running in production.

Tell me your problem. I'll build you a prototype.
Got an idea, or something that costs you time every week? Describe it in one paragraph. I pick a few ideas and build a clickable prototype, so you see the solution working, not on slides.
Describe it in one paragraph
A real problem from your business: something repetitive, manual or slowing you down.
I pick and build
I select a few ideas and build a clickable prototype in a few days.
You test it, no strings
You see the idea working. If it convinces you, we talk. If not, no problem.
Single-flow prototype. No real data, no integrations, no support. Just to touch the idea.
From Stuttgart to Madrid
At home in Madrid. German reliability, Spanish closeness.
Behind the technology is me: Martin Schenk.
I live in Madrid and have run my own company here, Martin Schenk S.L., since 1999. I specialise in what I do best and, honestly, what I enjoy most:
Building AI into the software you already use, and making sure it keeps working.
I'm not a faceless big agency. I'm your direct contact: the person who builds it is the person who looks after it afterwards. When you write, I answer myself, not a call center.
Latest from the blog
Honest notes from building in public, day to day.
My AI assistant runs my back office. I still press send myself.
Booking invoices, checking two bank accounts, chasing unpaid bills, preparing customer replies, looking after servers, keeping fifteen projects up to date, logging every AI expense down to the exact model, and a memory of 178,000 entries. How my own AI assistant is built, the guardrails it runs inside, and the one line it never crosses.

How I design onboarding and dashboards so users are not overwhelmed: one clear next step, three to five choices with a preselected recommendation, everything else one level deeper. Fewer options, backed by working memory research.

How to prove what a website said on a given date: two independent witnesses in Germany and France record robots.txt, ai.txt, TDM opt-outs, DNS and agent endpoints every night, seal the day, and anchor it with a qualified eIDAS timestamp anyone can verify.
