Sentia
Zagreb, Croatia
About
Australian-founded app development and UX/UI consultancy with a Zagreb-based EU delivery studio building web, iOS and Android products.
Our Take
Forty case studies are published across a portfolio that is almost entirely Australian—Airtasker, Shippit, RANGEme, Makita, Eclipx and Little Birdie among them—with clusters in fintech, property and healthtech.
Scale is claimed in aggregate rather than per project: 5 million-plus mobile app downloads and 15 million-plus web app users across the book, but the portfolio index carries no outcome numbers on individual engagements.
The Zagreb studio is the EU delivery arm of a Sydney company trading since 2006, so the commercial relationship and account management sit in Australia even when the build happens in Croatia.
Best for Australian or EU companies wanting a long-established delivery partner across fintech, property and health platforms, who are comfortable with a two-hub operating model.
Key strengths
- Forty published case studies is a deep book for a studio of this size, with real category depth: eight-plus fintech and financial services platforms, five property and built-environment tools, and five health and medtech products.
- Trading since 2006 with two verifiable addresses—83 York Street, Sydney and Radnička cesta 47, Zagreb—and marquee Australian marketplaces including Airtasker and Shippit.
Good to know
- The aggregate numbers (5M+ app downloads, 15M+ web users) span the whole portfolio; no individual case study on the index carries an outcome metric—ask what moved on two projects like yours.
- The client base is overwhelmingly Australian—ask for EU references and confirm which market's regulatory context the team has actually worked in.
- The rate in this listing comes from a single directory and the agency publishes none—confirm the band, and whether Zagreb and Sydney bill differently.
