About
Hi, I'm Josip 👋
Founder @ Sibence Digital
When I started messing with tech I did a lot of random stuff. Wrote processor emulators for fun, built robots that navigate labyrinths.
After working for a marketing agency and a couple of startups, I realized the rapid development of marketing technology that was happening right now.
And the direction where it was heading got me excited.
That's how I ended up building tech for marketers. Doesn't matter if it's as simple as building a custom GTM tag or designing data pipelines in BigQuery.
What matters most to me is building things that provide value for you, at every step of your marketing journey.
