# DDQ B.V.

Cutting-edge private AI and technology, available now. DDQ helps companies and institutions put advanced AI, autonomous agents and automation to work privately and under their own control. A small senior team designs, builds and operates secure solutions for the European reality.

## What DDQ offers now

Companies and institutions need useful AI and automation now, but many cannot expose confidential information to public platforms, wait for enterprise suppliers or build an internal AI department.

Bring DDQ the goal, workflow, sensitive body of knowledge, existing system or difficult technical problem. DDQ selects and combines the necessary technology, builds a working solution and can operate it on the customer's infrastructure or DDQ's privately operated infrastructure.

## Three ways to engage DDQ

### Build and operate digital products

Applications, production backends and privately operated infrastructure, with sensing or dedicated hardware when the product requires it.

Includes: Application development, Backend development and hosting, Autonomous and sovereign hosting, Scientific and integrated technology.

### Put private AI to work

Private language models, RAG, model evaluation and fine-tuning, bounded autonomous agents, workflow integration and agent-ready services.

Includes: Private LLM hosting, RAG and fine-tuning, Autonomous agents and agent-ready services.

### Deliver research and funded innovation

Open-science and EOSC implementation, citizen-science technology, technical proposal development, autonomous scoring and substantive delivery after an award.

Includes: Open science and EOSC implementation, Grant and subsidy proposals.

Full service and capability catalogue:

- Application development — Mobile and web applications, from the first working version through store distribution, maintenance and long-term operation. DDQ has shipped medical, scientific, industrial and public-participation software since 2010.
- Backend development and hosting — APIs, databases, data pipelines, identity, integrations and production backends, built and operated as one responsibility rather than handed between suppliers.
- Autonomous and sovereign hosting — Private infrastructure on customer hardware or servers owned and operated by DDQ in the Netherlands, with open-source components, strong authentication and reduced hyperscaler dependence.
- Private LLM hosting, RAG and fine-tuning — Open-weight language models hosted privately, connected to approved organisational knowledge with retrieval-augmented generation, evaluated and fine-tuned when model adaptation is the right technical choice.
- Autonomous agents and agent-ready services — Bounded agents that work with approved tools and information, plus MCP, WebMCP, authentication and discovery layers that make websites and services usable by other agents.
- Open science and EOSC implementation — Interoperable research services, FAIR data workflows, citizen-science platforms and practical European Open Science Cloud integration, backed by substantive H2020 COS4CLOUD and MONOCLE work.
- Scientific and integrated technology — Software combined with sensors, signal processing, machine learning, mobile devices or dedicated hardware for scientific, medical and industrial use.
- Grant and subsidy proposals — Call-fit assessment, technical concept development, TRL planning, proposal writing and autonomous scoring, followed by delivery of a substantive DDQ work package when the proposal succeeds.

DDQ's range is presented as a connected engineering capability, not eight separate departments. Customers enter through one of three broad needs. DDQ then combines only the capabilities required for the job and takes a defined scope that a three-person senior team can own. Larger programmes are delivered with established research, technical and consortium partners.

## How DDQ works

Customers bring DDQ a subject, problem or opportunity. The team listens in depth, learns enough of the domain to become genuinely invested, and thinks alongside the customer about technology, regulation, implementation and funding. DDQ then builds the agreed work and remains loyal to the relationship and the system after delivery.

1. **Tell us what you are trying to achieve** — The customer brings the subject, problem or opportunity. A finished specification, chosen technology or matching service label is not required.
2. **We listen, learn and become involved** — DDQ talks with the customer in depth, learns the domain, asks technical and practical questions and starts thinking alongside the people who own the subject.
3. **Shape the technical and funding route together** — DDQ identifies the smallest serious first step, the wider opportunity, relevant constraints and partners, and whether the innovation and timing fit a European, national or regional grant.
4. **Agree a bounded first piece of work** — Before substantive research, architecture, proposal development or prototyping begins, DDQ and the customer agree scope, responsibilities, rights and a direct, co-funded or funded payment route.
5. **Build it and stay** — DDQ delivers the agreed system or work package, validates it with the customer and domain experts, and remains committed to the relationship through operation, maintenance or a responsible transfer.

Commercial routes:

- Direct assignment — The customer funds the scoped work directly when speed, certainty or programme fit makes that the right route.
- Co-funded development — A grant covers part of the eligible project costs and the customer or consortium covers the balance.
- Funded DDQ work package — In some programmes, all of DDQ's eligible work can be covered by the award. Other customer contributions, responsibilities or costs may still apply.

Enthusiasm and an exploratory conversation do not create an unlimited free consultancy. When the work moves into substantive research, architecture, proposal development, prototyping or implementation, DDQ agrees a bounded scope, responsibilities, rights and a direct or grant-supported payment route. This protects the attention and loyalty that make the relationship valuable.

Proposal collaboration: DDQ's work is often grant-friendly because it combines genuine technical uncertainty with a practical route from a lower technology-readiness level to a working, validated system. DDQ assesses whether customer or partnership development may be funded, shapes the technical concept and TRL progression, uses autonomous tooling to score drafts and find gaps, defines a credible work package and stays to deliver the funded work. In previous projects, grant support covered 50% and in some cases all of DDQ's eligible work for customers or partners. Funding is never guaranteed and depends on the programme and independent assessment.

### Operating model and guardrails

DDQ is deliberately small. Customers work directly with Norbert, Joep and Demelza. Decisions do not move through departments, and automation handles much of DDQ's administration and internal operations. This produces unusually fast execution and directs more of the customer's budget to senior technical work.

DDQ does not claim the customer's medical, scientific, legal or operational authority. Qualified owners retain domain decisions. Scope, permissions, evidence, security, logging and human control are made explicit for each system.

## Origin and direction

The name DDQ was originally imagined as an alternative to DDS, De Digitale Stad, one of the pioneering Dutch online communities. It later became a convenient, memorable digital address. In 2010, DDQ became a technology company during the first generation of native app development.

The next generation of useful AI will not live only in software. DDQ is building toward systems that connect physical measurement, dedicated hardware, local inference, autonomous agents and sovereign infrastructure. The aim is technology that can observe, reason and act while remaining under the operator's control.

DDQ became a B.V. in 2018 and is now a team of 3. Its work has progressed from native apps to sensing, machine learning and autonomous AI for medical, scientific and industrial applications.

## People

You work directly with Norbert, Joep and Demelza. We are technically strong, supportive, enthusiastic and clear communicators who care deeply about the work itself. Automated overhead lets this small senior team move unusually quickly and put more of a customer's budget into the work. We never pretend to know a customer's field better than they do; we learn enough to think alongside them and bring an extra technical edge.

We do cool things. DDQ travels the world to help set up scientific campaigns and spread the practice of crowd and citizen science—from the Arctic to Zimbabwe. We plan that travel to minimize its environmental impact wherever practical.

## Principles

- We evaluate new technology early and use it where it has a practical advantage.
- Science advances when knowledge, instruments and participation are open.
- We prefer open source and open-weight models whenever possible.
- Privacy and security are architectural requirements, especially in medicine.
- Your data, infrastructure and technological future should remain under your control.
- A small senior team, no bureaucracy, direct contact with the people who build.
