About

Waterglass is a Vienna AI agency working across the DACH region, covering strategy, agent builds and ongoing operation on European infrastructure, with a venture studio alongside the client practice.

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+ organisations 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
