Demiurgo Soluciones Tecnológicas is a development studio based in Nigrán (Pontevedra, Spain) that works remotely for clients across Spain. We build custom WordPress plugins and PHP modules, websites and web applications in HTML, JavaScript and React, private intranets and member portals, and integrations that connect ERP and CRM systems with websites, including closed and industry-specific ERPs.
We also fix WordPress speed problems at the source, measuring before and after with the same method, write Python automation for repetitive work and data processes, and prepare a company's data and systems so language models can work with them: structured data, APIs, RAG and custom integrations.
Companies talk directly to the person who writes the code, with a fixed written quote before starting, delivery in phases and one month of adjustments included after delivery. Communication and marketing agencies get a white-label technical partner: their client sees their brand, quotes arrive within 48 hours and we communicate through the agency's own channel (Slack, Teams or email), with no direct contact with the end client unless the agency asks for it.
Everything we deliver is tested and documented so another developer can maintain it years later, with no lock-in. Recent work includes moving a group of four websites tied to a closed ERP to a single technical provider, a full WordPress clean-up with a new member portal and AI-ready indexing for a large fruit and vegetable group, and a direct MemberPress to HubSpot connector for an international analysis publication with thousands of paying subscribers.

Describe the scope of work in detail. Please include a summary of key deliverables.
Demiurgo works as our white-label technical partner. We are a communication and marketing agency, and they handle the development and technical side of the websites we manage for our clients, under our brand and without direct contact with the end client unless we ask for it.
The work is ongoing and covers several areas: WordPress maintenance and security for our client portfolio, including the clean-up of a site infected with SEO spam and hosting migrations to a new provider with separate cPanel accounts per client. Custom development on client sites: functionality built with snippets and small plugins (for example, manual product ordering by category combined with private product filters, age-gate fixes, SMTP and email logging), so we avoid adding paid plugins.
E-commerce integrations: technical support for connecting a PrestaShop store with the client’s ERP, and product feeds for Google Merchant Center generated without third-party plugins. Technical SEO and preparation for AI search: robots.txt, llms.txt and JSON-LD structured data on several client sites, plus technical audits that feed into our SEO and GEO reports.
Monitoring: an automated system that collects weekly data from Search Console, Bing Webmaster Tools and PageSpeed for a dozen client sites. What we value most is that we can sell technical projects we could not deliver in-house, with fixed quotes and documented work that we fully understand.
RESULTS & FEEDBACK
What were the measurable outcomes from the project that demonstrate progress or success?
The clearest result is capacity: we now deliver technical projects that we previously had to turn down or subcontract piecemeal, such as ERP integrations, custom functionality and technical SEO for AI search, all under our own brand.
Weekly monitoring now covers around a dozen client sites (Search Console, Bing Webmaster Tools and PageSpeed), so we spot drops and errors before the client does, without anyone checking each site by hand. A client site infected with SEO spam was cleaned and secured, and several sites were migrated to a new hosting provider without downtime. Response times have been within 48 hours and quotes arrive in time for us to close our own proposals.
Describe their project management. Did they deliver items on time? How did they respond to your needs?
Each request starts with a written, fixed quote before any work begins, which lets us price our own proposals with confidence. Larger jobs are delivered in phases, so we can see progress and show it to our clients along the way. Communication goes through our usual channels and Demiurgo stays in the background, so the client only sees our agency.
When an issue comes up on a live site, they react within hours and explain in plain terms what happened and what was fixed. Deadlines have been met consistently. When a request turned out to be bigger than expected, they told us before starting rather than after, and we agreed the scope again. Everything is documented, so our team understands what was done and can explain it to the client.

What did you find most impressive or unique about this company?
They understand how an agency works from the inside. They know that we sell the project to the client, that our name is on it and that we need answers fast to close proposals, so they adapt to that instead of asking us to adapt to them. The person who answers our questions is the same one who writes the code. There is no account manager in between, which saves a lot of back and forth when something is urgent.
They also solve problems at the root. Instead of adding another paid plugin, they usually build exactly what the site needs and leave it documented, so client sites end up lighter and easier to maintain over time. Finally, they are already working on what comes next for our clients: preparing websites so that AI search engines can read and cite them, which is now part of the service we offer.
Are there any areas for improvement or something Demiurgo Soluciones Tecnológicas could have done differently?
Their technical documentation is very complete. Sometimes we needed a shorter, non-technical summary to pass on to the client, and we had to write it ourselves. They now provide it when we ask.
