About
Waterglass is a Vienna-based AI company. We help businesses find out where AI actually pays off, build it, and run it on European infrastructure.
1. AI Consulting We advise you on which use cases AI is genuinely good for, implement the solutions and take care of running them, from first pilot to daily operation for your team, across industries.
2. Waves, our AI agents platform Your team builds its own AI agents: virtual team members that handle recurring work around the clock, connected to your existing tools and permissions. We run them on European infrastructure.
3. European AI infrastructure We run your AI projects on open models hosted in Europe, so your data stays under EU jurisdiction. On request we distill a smaller model of your own from your usage and bring your running cost down.
Who They Work With
Venture teams and platform businesses building an AI product from zero, with GDPR settled before the first line of code.

Our Take
Four named clients are published—InStaff, notus, HHLA Next and Heylog—but each is a single line rather than a case study, and the "read case study" links did not resolve at review.
The stronger evidence is the venture side, which is verifiable independently: Notehouse, a HIPAA-compliant case-management product used by 250+ organizations and acquired in 2025, and Pxl, a QR and microsite builder with 100 million interactions now being rebuilt as an agentic business.
The site is unusually straight with buyers—it states plainly that there is no Munich office and that on-site work means travel, which is the kind of answer most agencies bury.
Best for DACH businesses that want an AI agent built, run and hosted in Europe by a team that also builds and operates its own products.
Key strengths
- Operates what it builds—monitoring, model changes and new requirements are named as an ongoing service, not a handover
- European hosting with model residency in Germany or the EU on request, documented per data flow
- Two acquired products of its own, so the AI-build claim is testable outside client references
Good to know
- Client work is published as one-line summaries with no reachable case studies—ask for a reference you can speak to
- The company is recently formed and publishes no headcount; ask who would staff the build
- Vienna-based and open about it: on-site days in Germany mean travel, remote for the rest
