What do you need to build?
Pick the sentence closest to your situation. Where a published project backs it up, we cite it.
I have an idea and want to validate it
MVP development for startups
A first version to validate with real users. We built Tasaciones.com from scratch.
View serviceI need an app for iOS and Android
Mobile app development
Hybrid apps with Ionic and Angular. We built the Mallorcab apps, a platform with more than 3 million services created.

Custom software
Internal tools and backoffices built around your process, like the order system for Deliciosos Ramos.

SaaS development
Plans, payments and usage limits. We built Rescrito, an AI SaaS with real users and recurring payments.

View serviceI need a chatbot on my website or Telegram
AI chatbots and assistants
Chatbots for your website or Telegram, with handover to a human. For Inferno IA we built a custom one on top of AlisaBot.

Agents that query systems and carry out steps, with human approval when needed. We built ClipToTask, which turns screen recordings into tasks.
View serviceWe want to use ChatGPT, Claude or Gemini with our data
AI integration
OpenAI, Anthropic or Gemini models connected to your systems, chosen for quality, cost and privacy. SacaNota combines OpenAI and Gemini.

RAG for business
Answers based on your documents, with permission control and sources. We built one on the Mundomar Cruceros catalogue.

Automations
CRM, ERP, Stripe, email and WhatsApp connected. For Soñar Despierto we linked their website and Google Sheets in both directions.

Only the features your team uses, with AI. If HubSpot or another off-the-shelf CRM works for you, we will tell you.
View serviceI have software or an app that needs maintaining or rescuing
Software maintenance
We tidy up, fix and evolve platforms that are already live. We maintain Mallorcab and the Soñar Despierto website in production.
View serviceI do not know where to start with AI
AI audit
Prioritised opportunities, estimated return, roadmap and recommended architecture. The report is yours.
View serviceI want to apply AI across the whole operation, not to a single task
AI transformation
Three levels: automate, connect or build your own AI workspace. If your ERP works, it stays.

Do you have anything specific for my sector?
Yes: eight sectors have their own page. They are proposals, not case studies: apart from Tasaciones.com, which is close to real estate, we do not yet have public projects in them.
| Sector | What we propose |
|---|---|
| Law firms | AI copilots and internal software. |
| Accountancies and tax advisers | Operational WhatsApp and internal AI. |
| Insurance brokers | Renewals, claims and operational WhatsApp. |
| Property managers | Incidents, owners’ meetings and an owner portal. |
| Recruitment firms | Semantic candidate search and shortlists. |
| Real estate agencies and developers | Client-property matching and viewings. |
| Consultancies | Internal search and assisted proposals. |
| Private clinics | Appointments, follow-up and a patient portal. |
How do you work and what is the minimum?
There are three ways to engage for the same software. Projects start at €1,000 and delivery from 2 weeks; not every model fits every project.
| Model | How you pay | When it is yours | Fits if… |
|---|---|---|---|
| Fixed-scope project | Initial payment plus milestones. Lowest total cost. | On completion, with code and access. | The scope is clear. |
| Flexible payment | Payments spread over 6 or 12 months. It is a payment term, not a delivery term. | When the payments are completed. | You want to preserve liquidity. |
| Build & Run | Initial fee and monthly fee; usual commitment of 12 or 24 months. | Purchase option defined from the start. | You do not want to deal with hosting, security or support. |
Details of each model in ways of working.
What technology do you work with?
With stable technology, chosen for each project and without being tied to any vendor.
We use Angular, Ionic and TypeScript on web and apps; Node.js, NestJS, Python and FastAPI on the backend; PostgreSQL, MongoDB, Redis or Firestore for data, and Docker with CI/CD to deploy. In AI we integrate OpenAI, Gemini, Anthropic, DeepSeek or Perplexity depending on quality, cost, speed, privacy and type of task. Details by layer in technologies we work with.
When are we the right choice and when not?
We are the right choice when someone has to build the system, not just recommend it.
We fit if…
- Your work lives between email, spreadsheets and tools that do not talk to each other.
- You need AI connected to your data, not a loose chat.
- You want to launch a SaaS, an app or a backoffice and then operate it.
We are not the right choice if…
- You only need a campaign, content SEO, branding or a WordPress theme, with no product to build.
- A ready-configured off-the-shelf SaaS is enough for you.
- You want to rent individual developers, with no product brief.
- You need legal advice.
- Your budget is under €1,000 or delivery has to be in under 2 weeks.
What have we already built?
More than 50 projects since we started. Three of them:
Frequently asked questions
What exactly does Digitup Studio do?
Digitup Studio is a technical studio in Madrid that designs, develops and maintains custom software: MVPs, iOS and Android apps, SaaS, internal tools, CRM, chatbots, AI agents, RAG and automations. It takes each project from idea to production. It is not a campaign agency and does not resell licences: if an off-the-shelf SaaS already solves your problem, it will tell you.
Do you only work in Madrid?
No. Digitup Studio is headquartered in Madrid, at Calle Alcalá 211, but we mostly work remotely, with companies from different parts of Spain and on international projects. Mallorcab, for example, is a mobility platform for taxis in Mallorca. We meet in person when the project calls for it, and we can work in Spanish, English or Russian, depending on the project.
What is the minimum project?
At Digitup Studio, projects start from €1,000 and delivery from 2 weeks. Above that there is no published ceiling: the price depends on what the system has to do, which channels it runs on, which tools it connects to and how much information it handles. A simple chatbot for a website is close to the minimum; integrations or custom software raise the price.
Can you work on software we already have?
Yes. At Digitup Studio we step into existing projects to tidy the architecture, improve performance, add AI, automate processes or scale features, and afterwards we can maintain them in production. We also know how to work alongside other teams: on the amateur football app Scouz we took part in the development. If your ERP or CRM does its job, it stays and we build the missing part.
Who runs the project?
The two partners of Digitup Studio run it directly: Stas Nikitin, CEO, handles product, strategy, business and project management, and Anton Zverev, CTO, handles architecture and development. Depending on the project, specialists in UX/UI, frontend, backend, DevOps, QA, data or AI join in, but the people in charge do not change. We do not hand the project to a junior team after the first meeting.
How do we get started?
Tell us the problem or the idea from the contact page, or book a free 30-minute call with Anton Zverev, CTO of Digitup Studio, with no commitment, on working days from 10:00 to 18:00 (Madrid time). We review the case, propose a technical approach and phases, and if it fits we start with a first version. If it is not worth building, we will tell you that too.
Can’t find your case in the list?
Tell us the problem in two lines and in 30 minutes with Anton we will see whether it is worth building.
