nexus
nexus is an AI-native intelligence platform from German publisher TILLER ALPHA, built to analyse user communities, multi-institutional collaborations and emerging research themes at research infrastructures. It is sold through direct contact, with no public pricing and no self-service access.
What is nexus?
nexus is the flagship product of TILLER ALPHA GmbH, a small Bonn-based publisher, and is presented as the first AI-native intelligence platform designed for the strategic analysis of user communities, multi-institutional collaborations and emerging thematic trends at research infrastructures. Its raw material is the paperwork such organisations already generate: reports, project proposals, reviews and administrative metadata. The platform applies network science, machine learning and natural language processing to turn that unstructured material into a picture of who uses a facility, who collaborates with whom, where funding flows and which topics are rising.
The positioning is deliberately narrow. Rather than a general analytics suite, nexus targets the governance problems specific to large scientific facilities, core facilities and technology platforms: justifying multi-million euro investments, demonstrating value to funders and political stakeholders, and aligning priorities with a scattered user community. Alongside the platform, the publisher offers the analytical services that surround it, including geospatial mapping of international collaboration networks, interactive network visualisations, KPI selection, user survey design and interview protocols.
Two claims distinguish the offer. The first is that it works on small data: the publisher argues that most AI models need millions of data points, whereas the specialised compact language models behind nexus deliver precision on something as modest as an organisation's last twenty project proposals. The second is European digital sovereignty, with the publisher stating that it owns the hardware and expertise to locally host, run and fine-tune models. The tone is pointedly anti-hype, promising a disciplined, expert-led process rather than drag-and-drop magic.
Delivery comes in two named forms: Continuous Intelligence, an ongoing engagement keeping a strategic landscape permanently current, and Insights Sprints, a project-based deployment answering one strategic question in weeks rather than months.
One practical caveat dominates. There is no public access. The site offers no account, no login, no demo and no trial; its only open call to action is a newsletter sign-up, and the application subdomain does not currently serve the product. nexus is engaged through conversation with the publisher, not adopted by self-service.

Pros & Cons
Pros
- Unusually precise specialisation in the governance of research infrastructures
- Founding team drawn from academic research on this exact subject, with published work listed
- Designed to deliver on small document sets rather than requiring large datasets
- European digital sovereignty positioning, with hosting and fine-tuning claimed in-house
- Named and checkable references, including European XFEL and the University of Bonn
- Purchasing Power Parity adjustment of fees for lower and middle-income countries
- A genuinely free Data Clinic offers a no-cost way to test the team's expertise
Cons
- No published price of any kind, so budget cannot be gauged without contacting the publisher
- No public access to the product, and the application subdomain does not currently respond
- No terms and conditions are published anywhere on the site
- No security certification is claimed and no data processing agreement is offered
- The privacy policy covers only the website, not data submitted to the platform
- A very young and very small publisher, registered in February 2025
- No API, no third-party integrations and no mobile application
Pricing & Plans
No price is published. The site carries no pricing page, and none appears in its sitemap; the publisher invites prospective clients to discuss terms directly. Fees and licensing costs are acknowledged to exist, and may be adjusted using Purchasing Power Parity data for research infrastructures in low and middle-income countries. There is no permanent free plan and no free trial of the platform. A separate Data Clinic consultation programme is offered free of charge, but it provides advisory support from the team rather than access to the product itself.
- Continuous Intelligence — an ongoing engagement keeping a strategic landscape permanently up to date
- no published price
- Insights Sprints — a project-based deployment answering one strategic question in weeks
- no published price
Data, GDPR & hosting
A consolidated view of how nexus handles your data.
GDPR overview
GDPR compliance is claimed explicitly twice. The privacy policy, effective 14 January 2025, states that personal data is handled in compliance with applicable law including the GDPR, and the services page promises a steadfast commitment to the responsible use of AI and GDPR compliance. The policy lists data subject rights article by article: access (15), rectification (16), erasure (17), restriction (18), portability (20), objection (21) and withdrawal of consent (7-3), with a stated response time of one month and hej@tilleralpha.com as the contact point. Encryption, secure servers and access controls are cited, and browser Do Not Track signals are respected. No data protection officer is named, and no Article 27 representative applies since the publisher is established in Germany. Note the scope: these commitments describe the website, not the nexus platform itself.
Who owns the data?
TILLER ALPHA GmbH is named as the data controller for the website, at Bonner Talweg 64, D 53113 Bonn, reachable at hej@tilleralpha.com. Beyond that, ownership of customer data is not addressed anywhere. The site publishes no terms and conditions, and its privacy policy governs only visitors to the marketing site, not the organisational data a client would submit to the platform. The publisher states that it does not sell personal data and shares it only with service providers and legal authorities. Anyone considering an engagement should therefore obtain written contractual terms covering ownership, licensing, reuse and deletion of submitted material before transferring anything.
Reuse rights
No published document grants an end user any right to reuse data obtained through the tool, because no terms and conditions exist on the site. For website data, the stated purposes are narrow: operating and maintaining the site, responding to enquiries, measuring audience performance and meeting legal obligations, on the basis of consent, contract, legitimate interest or legal obligation. Reuse rights over the analyses, visualisations and network maps produced during an engagement are simply undefined in public documents, and would have to be negotiated directly with the publisher in the engagement contract.
Data retention & training
Hosting summary
No hosting jurisdiction is contractually stated. The publisher makes a strong European sovereignty claim, saying that where your data lives matters and that it owns the hardware and the expertise to locally host, run and fine-tune everything from specialised small language models to large open-source models. That is marketing copy about the company's capability, not a published data residency commitment: no country and no region is named in the privacy policy or in any other document on the site. The only documented transfer outside the European Economic Area concerns Automattic, provider of the Jetpack Stats audience measurement used on the marketing website, covered by standard contractual clauses. Two technical observations, neither of them declared by the site, temper the sovereignty claim: the marketing site itself is served by WordPress.com infrastructure on a US anycast network, and the nexus application subdomain points to a container in Microsoft Azure's Germany West Central region. Prospective clients should require written hosting and residency commitments rather than rely on the website.
Things to keep in mind
Risks and trade-offs to weigh before adopting nexus.
- Network analysis can look objective while resting on incomplete or inconsistent administrative metadata
- Automated evidence used to justify funding decisions may crowd out judgement that data cannot capture
- Ownership and reuse of submitted organisational data are undefined, since no terms and conditions are published
- The privacy policy covers only the website, so platform data handling rests entirely on a private contract
- No data processing agreement, subprocessor list or certification is offered, which matters when facility user data is personal data
- The in-house European hosting claim sits oddly with a marketing site served from US infrastructure and a product frontend on Azure
- The product is not publicly reachable today, so commitments should be taken on contract rather than on the website
Setup & Integrations
Technical difficulty
Effectively none for the client, because there is nothing to install. The publisher runs an expert-led process and tailors the platform to each infrastructure, so the effort on the client side is organisational rather than technical: gathering reports, proposals, reviews and administrative metadata, and framing the strategic question to be answered. No technical documentation, API or configuration interface is published. The real constraints are securing an engagement and clearing internal data governance approvals to share organisational documents. Insights Sprints are announced as delivering in weeks rather than months.

Should you pick nexus?
nexus is a rare thing in an AI directory: a tool that knows exactly how narrow it is. It addresses the governance of research infrastructures, a world of large scientific facilities, core facilities and technology platforms whose managers must justify substantial public investment without ever having had good data on their own user communities. The founding team comes from academic research on precisely that subject, and the site lists both published work and named references, including a former managing director of European XFEL and the office for core facilities at the University of Bonn. The refusal to promise drag-and-drop magic, and the claim that useful precision can be reached on twenty project proposals rather than millions of data points, both read as the work of people who understand the constraint they are selling into.
The reservations are about maturity and paperwork rather than credibility. The publisher was registered only in February 2025 and describes a team of a handful of people. More importantly for a buyer, the contractual surface is thin: there are no terms and conditions on the site at all, no data processing agreement, no subprocessor list and no security certification, and the privacy policy explicitly covers the marketing website rather than the platform. The European sovereignty claim is prominent but is not backed by any published data residency commitment. And nexus itself is not publicly reachable today; its only open call to action is a newsletter sign-up.
The sensible reading is that this is an expert-led consulting engagement wrapped around a platform still finding its public form. For a research infrastructure with a concrete strategic question, the free Data Clinic is a low-risk way to test the team. Anything beyond that should wait for written answers on price, data ownership, retention and hosting.
