Notch
Zagreb, Croatia
About
Software and AI engineering partner (formerly Agency04) that builds digital products with UX/UI design embedded across delivery teams.
Our Take
Six customer stories are published against a client roster of Deutsche Telekom, STRABAG, Erste, Delivery Hero and 1WorldSync, and the tenure figures are the strongest signal—DigitalAI and T-Com at eight-plus years, STRABAG six-plus, Beeline five-plus.
The Candid engagement is the clearest process evidence: an AI discovery workshop run on design thinking, a time-boxed proof of concept across ten scenarios, then an MVP discovery workshop with stakeholders, advisors and designers, reporting CV creation cut from 45-60 minutes to around 15.
Positioning has moved decisively to AI-native delivery with two proprietary platforms, so design appears as one input to an engineering-led process rather than a standalone practice.
Best for enterprises modernising legacy systems or piloting AI features who want a long-tenure delivery partner; if you are buying design as the primary deliverable, confirm who leads it.
Key strengths
- Client tenure is documented rather than implied: DigitalAI and T-Com at eight-plus years, STRABAG at six-plus and Beeline at five-plus, which is unusual disclosure for an agency of this size.
- The Candid case study reports a measured 75% time saving, from 45-60 minutes to roughly 15, alongside a named discovery-to-MVP method.
- Operating since 2014 with a stated 170+ projects and a 4.9 Clutch rating, plus enterprise logos including Deutsche Telekom, STRABAG, Erste and Delivery Hero.
Good to know
- The site states 50+ professionals while this listing shows a larger band—confirm current headcount and how many people sit on your account.
- Most published stories describe AI and engineering outcomes; UX artifacts are not shown—ask for a project where Notch owned research and interface design.
- Two proprietary platforms (Sovera AI, NotchForge) sit inside the delivery model—clarify what you own at the end of the engagement and what remains licensed.
