Obsidiaan Tech is a technology company specialized in applied artificial intelligence, blockchain, cybersecurity and quantum computing. We combine research and innovation with tailor-made product development and AEO marketing: positioning brands inside AI assistants such as ChatGPT, Gemini and Claude. Powerful technology, made for humans.
Innovation here means smart contract development, private AI, cybersecurity and web products built to reach production: four disciplines we combine in the same project when it needs them.
TECHNOLOGY
FOR HUMANS
We work across eight areas: blockchain, web development, cybersecurity, artificial intelligence, post-quantum cryptography, backend, IT consulting and LLM marketing. We combine them according to what each project needs, not as fixed packages.
Smart contracts, dApps and secure, efficient decentralized solutions on EVM, L2 and sidechains.
Next.js apps, scalable SaaS and robust APIs focused on performance, SEO and accessibility.
Red team that attacks, blue team that defends and purple team that joins both: pentesting, hardening and detection across web, APIs and smart contracts, following OWASP methodology.
AI agents applied to real processes: automation, RAG over private data, fraud detection and copilots.
We integrate the NIST algorithms (Kyber, Dilithium) into systems already in production and encrypt signals against “harvest now, decrypt later”.
Services and APIs that survive production, in Rust, Go, Python or Node/TypeScript depending on what the project needs.
Strategic guidance on digital transformation, cloud architecture and stack selection.
Get your brand recommended by AI assistants. We position you inside LLMs and generative search (AEO/GEO) so ChatGPT, Gemini and Claude surface your business.
Scan your site free on PrimafonteWe combine eight disciplines that rarely coexist well: blockchain, web development, backend, cybersecurity, applied AI, post-quantum cryptography, consulting and AEO/GEO positioning. We do it so your product is fast, secure, verifiable and citable by AI.
We build production-ready decentralized infrastructure: audited smart contracts, DeFi protocols, asset tokenization and Web3 dApps.
Modern web applications and scalable SaaS: clean architecture, performance, accessibility and a flawless user experience.
We protect your stack end-to-end with red team, blue team and purple team exercises: real attack, defence and the joining of both, plus identity management and incident response.
AI integrated where it's actually useful: agents that automate processes, models that detect on-chain fraud and copilots that speed up your team.
We bring post-quantum cryptography to systems already in production: we integrate the NIST-standardised algorithms and encrypt signals and communications against the “harvest now, decrypt later” threat.
Services and APIs that survive production: Rust and Go when performance and concurrency dominate, Python when the data and AI ecosystem does, Node/TypeScript when sharing a language with the front end pays off.
Guidance before the first line of code: what to build, on which stack and with what risks. Digital transformation, cloud architecture and technology selection.
Positioning inside generative engines: getting ChatGPT, Gemini, Claude and Google's AI overviews to cite you when someone asks about what you sell. We measure before and after rather than asserting it.
We build tools for our own work and open them to the public. They are not demos: we use them on real projects before we show them.
Purple team of AI agents
AI agents that attack and defend the same system in the same cycle, to find what an isolated test cannot. Open source and auditable: you can read all of it, it is not a screenshot in a slide deck.

Visit productSix delivered projects across fintech, carbon-credit banking, publishing, tourism and SaaS: a private blockchain to anonymize transactions, private AI to enrich catalogues, and self-learning RAG systems.
Blockchain · FintechWe developed a private Ethereum-based blockchain solution that helped anonymize financial transactions for a world-leading fintech company.
AI · Asset ManagementWe implemented an AI system that improved the metadata usage of one of the largest funds in Germany, helping develop various AI tools for operational efficiency.
SaaS · WebWe created a web solution built with modern languages for a startup, successfully launching a new SaaS (Software as a Service) product. We are experts in web application development.
AI · TravelWe built a tourism experiences portal in Spain powered by a self-learning RAG AI system that connects 300+ experience providers and 1,000+ experiences, recommending the ideal activity to each traveler and getting smarter with every interaction.
Software · SustainabilityWe developed a carbon credit offsetting system for a Swiss carbon-credit bank, enabling companies and institutions to offset their carbon footprint in a fully traceable and verifiable way.
AI · PublishingWe implemented a private AI system to improve the metadata used by one of the world's largest publishing groups, of German origin, boosting catalog accuracy and operational efficiency without exposing sensitive data.
We helped develop an advanced AI-based platform designed to integrate seamlessly with your company — speaking its language, understanding its unique business context and keeping your most confidential data secure, making it far more than just a chatbot.
Seven groups of tools, from AI agents and models served inside your own perimeter to Solidity and Solana, backend in Rust, Go and Python, Next.js, and post-quantum cryptography standardized by NIST.
The core of our AI work: agents that chain tasks together and consult your own data before answering, instead of just generating text.
Language models run where they belong: served with Ollama inside your own perimeter when the data cannot leave, or third-party when it does not have to be.
Audited smart contracts in Solidity on Ethereum and its L2s, and in Rust on Solana.
Production services and APIs: Rust and Go when performance and concurrency dominate, Python when the data and AI ecosystem does.
Applications and SaaS built with Next.js and React on TypeScript, focused on performance, SEO and accessibility.
Containerized deployment on GCP, and Rust or Go when performance or memory safety is what matters.
Kyber (ML-KEM) and Dilithium (ML-DSA), the standards NIST published in 2024 for quantum-resistant encryption and signatures.
Beyond client work, we research frontier technology. Early-stage explorations that keep us — and our clients — ahead of the curve.
We track the frontier: new schemes, cryptanalysis and when what we use today stops being safe. Integrating it into real systems is no longer research, it is a service.
We design end-to-end encrypted communication channels for confidential, tamper-proof information exchange.
On-board perception and navigation: detection at the edge, trajectory tracking and autonomous decision-making when the link to the ground is unreliable or absent.
Signal processing for detection and tracking: fusing radar with other sources, trajectory estimation and separating target from noise.
We are exploring the Internet of Natural Things: bio-inspired networks that turn the natural world into living, connected infrastructure.
Obsidiaan Tech is a technology company based in Granada, Spain, specialized in Blockchain & Web3, applied Artificial Intelligence, Cybersecurity and Web Development. We build secure, scalable and verifiable products for companies and institutions.
LLM marketing, also called Answer Engine Optimization (AEO) or Generative Engine Optimization (GEO), positions your brand so AI assistants like ChatGPT, Gemini and Claude recommend and cite it when someone asks about your sector. It is not the same as SEO: a model does not reward your domain authority, it rewards content it can extract, attribute and verify. You can measure where your site stands today with Primafonte, our free Citability Index scanner. This site scores 94 out of 100 on that index.
Yes. We design private AI systems where models run inside your own perimeter and reason over your data without sending it to third-party services, combining modern AI capability with full data confidentiality.
Yes. We audit smart contracts, web and APIs — covering reentrancy, access control, economic attacks and gas optimization — combining automated tooling with expert human review before deployment.
We are based in La Herradura, Granada, Spain, and work in English and Spanish with clients internationally.
