how i workyou first

Woman walking with determination on an orange background: how Netneo works, the client's business first

I work with businesses that live on getting people through the door. That's why I don't sell pages: I sell people walking in.

Before we talk about budgets, we talk about your business: where your customers come from today, what eats up your time, and what happens when someone looks you up on Google and can't find you. The project comes out of that conversation, not the other way round.

  1. A phone ringing with an incoming call: the first conversation, 30 minutes and no strings attached

    listen

    A 30-minute call, no strings attached and no jargon. You tell me how your business works and what you want to change.

    How long:
    30 min · this week
    You get:
    a written diagnosis: what's failing today and what I'd fix first.
    Your part:
    tell me how your customers find you today.
  2. A hand holding the folder with Netneo's collaboration agreement

    decide

    I tell you what I would do, what it costs and how long it takes. In writing and with dates. If you don't need something, I'll tell you that too.

    How long:
    proposal in 48–72 h
    You get:
    fixed price, scope and dates. No surprises halfway through.
    Your part:
    say yes, no or "change this".
  3. A laptop showing the Ovetus app, built by Netneo

    build

    I develop it myself, start to finish. You approve the design before a single line of code exists, and the result before it goes live.

    How long:
    4 to 6 weeks depending on the project
    You get:
    your website or app live, in your name, with the access handed to you.
    Your part:
    approve the design and review before going live.
  4. A monitor showing the monthly visits and contacts report for a website built by Netneo

    measure

    Going live isn't the end. With the maintenance plan, every month you see how many people searched for you, how many came in and how many got in touch, and we decide together what to improve.

    How long:
    every month, with maintenance
    You get:
    your own results dashboard: clear, no jargon, right on your phone.
    Your part:
    open the link (it takes a minute to read).

  • Vengo trabajando con Mario hace unos meses con mi proyecto y la verdad que venimos muy bien. Yo lo recomiendo mucho ya que en mi caso en un MVP entonces necesitaba a alguien confiable con el que pueda trabajar tranquilo ya que yo solo puse la idea.

    En mi caso fue una plataforma para gastronomicos y quedo perfecto. Si necesitan alguna referencia la plataforma es "Gastronomiate".

services

in depth

I analyse your business first, and only then do we set a goal that is clear and measurable

Sometimes you need a new website. Other times the problem lies in a process, in visibility, in conversion or in a tool that no longer works. My work starts by finding out what the business really needs. I work from Oviedo with businesses in Asturias, the rest of Spain and Latin America.

Every month you see the numbers: how many people searched for you, how many came in and how many got in touch

  • build

    A solid foundation for your business to take off.

  • improve

    What already works, so it performs better.

  • automate

    Key processes, so you gain time and scale.

“My website doesn’t reflect what I do, and it doesn’t bring me clients either”

Web design and development

I design and build websites made to be understood, to convey what your business does and to turn visits into clients. From structure and experience to visual design and final development.

Strategy · UX/UI · Digital identity · Development · Ecommerce · Custom websites

Let’s talk about your website

“I need a tool that doesn’t exist”

Custom software

Applications and platforms built around how your business really works, not the other way round.

Web applications, platforms, dashboards, internal tools.

Let’s talk about your tool

“My competitors show up before me”

SEO and GEO

Get found on Google when someone searches for what you do in your city, and get recommended by AI. Content and architecture to appear both in search engines and in answers generated by artificial intelligence.

Technical SEO, architecture, content, generative engine optimisation.

Process automation

What you do by hand today can run on its own. I connect your tools so repetitive work stops eating up your hours.

questions

Any questions before you write to me?

  • With me, Mario Rivera Valverde, the founder of Netneo. I design and build every project from start to finish, from Oviedo, with no middlemen and no accounts passed from hand to hand. When you write, I’m the one who answers.

  • A professional website starts at €490. The final price depends on the number of sections and on whether you need copywriting, languages or an online shop, and I give it to you fixed and in writing within 48–72 hours, before we start.

  • A website of up to 5 sections is ready in about 4 weeks. Bigger projects take 4 to 6 weeks, and before we start I give you a written schedule, with dates.

  • The first results on Google usually arrive 2 to 4 months after launch. From day one your website is set up in Search Console and on your business profile, and every month a report tells you how many people searched for you and found you.

  • Yes. The domain, the website and its content are in your name, and if you ever stop working with me, you take them with you. No lock-in and no strings attached.

  • Yes. Your website comes with its own panel so you can change the texts and photos yourself, without touching code, without plugins and without updates that break anything. It’s included from the €490 pack. I built it myself, so if you need to edit something else, I add it to the panel. And if you’d rather not touch it, just ask me and I’ll change it.

  • With maintenance, from €29 a month, your website stays up to date and every month you get a report of visits and enquiries. If you need changes, you write to me and I make them; and if you want to grow, we add SEO or automations when it makes sense.

  • No. I work from Oviedo with businesses all over Asturias, where I can meet you in person, and remotely, by video call, with clients in the rest of Spain and in Latin America.

  • Before we start you get a fixed quote in writing. Payment is by bank transfer, in two parts: half to get going and the rest at launch. Maintenance and SEO are paid month by month.

My clients don’t come to me saying “I need a headless architecture”. They say “my website doesn’t sell”. Tell me in your own words; translating it is my job.

Tell me what’s going on

I reply myself within 24 hours, not a salesperson.
