Custom Software Development for Companies

We design, architect and build exclusive, scalable technology solutions adapted 100% to your business rules. We work across six areas: core systems and custom development, AI and LLM model integration, AI agents and custom copilots, AI-first SaaS platform development, API architecture and middleware, and evolutionary maintenance with MLOps. We serve companies in Tarragona and across Spain.

Your company does. When you work with Macaque Consulting, you retain full intellectual property of the source code, architecture and documentation of the software developed. You do not pay per-user licences or depend on a single provider to evolve your technology (vendor lock-in): you can maintain it with your in-house team, with us or with whoever you choose. Your custom software becomes a proprietary asset that increases the value of your company.

It depends on the scope, functional complexity, required integrations and the level of artificial intelligence it incorporates. That is why we start with an analysis phase in which we define requirements, architecture and priorities, and give you a fixed budget and delivery plan. We work in phases using agile methodologies: we launch the highest-value features first, and AI-assisted development shortens timelines compared with traditional development.

We integrate large language models (LLMs) from providers such as OpenAI, Anthropic or Meta into your applications through APIs or private deployments, depending on your privacy and cost requirements. We connect them to your data and systems using techniques such as RAG, so the software can understand documents, answer queries, classify information or automate decisions with the real context of your business. We choose the right model for each use case, without tying you to a single provider.

A custom AI copilot is an intelligent assistant built into your work tools and trained on your company's knowledge: procedures, catalogues, contracts, historical records or internal policies. It helps each employee in their day-to-day work, drafting proposals, analysing documents, preparing reports or guiding complex processes step by step. Unlike generic tools, it knows your business and protects your confidential information.

An AI-first SaaS platform is software as a service designed from the outset with artificial intelligence at the heart of its value proposition, not as a later add-on. We develop the multi-tenant architecture, security, subscription billing and AI model integration, and prepare it to scale to thousands of users. With MLOps and evolutionary maintenance, the models are continuously monitored and improved after launch.
