Three Days, One Series C, and Way Too Much Coffee
There are weeks you forget by Friday, and there are weeks like last one. September 2 to 4 ran me ragged, and I wouldn't trade a single hour of it.
Day 1: Series C and the Secret We'd Been Sitting On for Weeks
It all started with a number. Wonderful officially closed a Series C of $550 million, at a $5 billion valuation (up from $2 billion just six months earlier). The round was led by Insight Partners, with Salesforce joining as an investor for the first time, alongside existing investors Index Ventures, IVP, Vine Ventures, 9Yards, and Bessemer Venture Partners staying on.
What makes this news special isn't just the figure. Wonderful is less than two years old, and in that time it has built something investors at this scale are willing to back with half a billion dollars. That doesn't happen by accident.
With this round comes a redefinition of what Wonderful actually is. We're no longer talking about an agent platform or a chatbot layer. Wonderful now positions itself as an AI operating system for enterprises: the infrastructure layer where AI gets built, deployed, and governed inside real business processes, not demo environments.
For the regional team, this also means concrete growth. The Adriatic team, currently just under 20 people, plans to add around ten more positions by the end of the year.
Day 2: The AI Leaders Lunch at Tolstoy
While the Series C news was making its way around the region, we were already onto the next phase. The AI Leaders Lunch, a format we've been carefully building as a gathering for a select group of guests, took place at the Tolstoy Members Club.
This wasn't another networking event with business cards and bad coffee. The idea behind AI Leaders is simple: bring together the people actually making decisions about AI transformation, no pitch, no sponsored content, just an honest conversation about what works and what doesn't. Wonderful shows up here as the owner of the format, not as a "partner" in fine print.
The Series C news, announced just a day earlier, gave this lunch a particular energy. Nobody at the table needed convincing that AI transformation was real. The conversation had already moved on to where it gets hard.
Day 3: Mr. Wonderful Takes the Main Stage at AI Tech Summit
And then came Sava Centar. A few days earlier, a Blic Biznis interview had already put Vedran's appearance on people's radar, with a line that stuck: AI isn't the future, it's a condition for survival. So when AI Tech Summit Belgrade opened, two days of conference, Mr. Wonderful took the main stage with a talk we'd been building for weeks, and the room already knew to expect him.
Vedran's talk wasn't a product pitch in disguise. It was built around three lessons from real enterprise work:
Lesson one: once you open the door with one AI use case, the whole building is behind it. An anonymized example from a large regional telecom operator showed how a project that started as customer support expanded into security, field service, and billing.
Lesson two: reading is safe, writing is real. Through a banking and lending example, Vedran laid out why the gap between AI that reads data and AI that makes decisions and writes into systems is enormous, and why that's exactly where the real value, and the real risk, live.
Lesson three, and this is where the talk built to its close, was the compounding effect of the platform itself. Every new client, every new use case, makes the next one faster and easier. The Series C, announced just a day earlier, served as living proof of that thesis. Investors don't put half a billion dollars behind a story. They put it behind a proven effect.
The Story Travels
The news didn't stay in one place for long. Within days, the Series C story was picked up across the region: Bloomberg Adria's North Macedonia and Croatia desks, Lider, Forbes Croatia, Netokracija, and Portfolio in Hungary all ran it. Then came the piece I'm proudest of, a phenomenal in-depth interview with Vedran in Nedeljnik, going well beyond the funding number into the AI OS positioning and the real lessons from running enterprise AI live.
A few days later, the Bloomberg Adria studio segment out of Zagreb kept the story going, one conversation, broadcast across Bloomberg Adria's network into North Macedonia, Serbia, Bosnia and Herzegovina, Slovenia, and Croatia at once. Same story, same person, one regional stage instead of five separate pitches.
The People Behind the Week
None of this happens with one person on a stage. This week ran on a team I'm genuinely proud to work with, Miloš, Krešo, and Vedran on the ground in Belgrade, with Petar in Hungary and Petras in Lithuania backing it up from their markets. Different cities, different languages, same standard.
And tha Belgrade week is only the opening chapter. Vedran's keynote here was, in more ways than one, a preview of what's coming on September 15, when we head to Vilnius for Google Cloud Day. For me, that one carries something extra: it's my first time back in Vilnius in fifteen years, and I couldn't be happier that it's this trip that gets to be the one.
Why I'm Writing This Down
Because it's rare for a funding announcement, your own event format, and the main stage of the region's biggest AI conference to land in the same three days, with the same client, the same story, and the same person on stage. This was the week Wonderful went from "promising startup" to "a company the region takes seriously." We got to help build that from the inside.
Chaotic? Absolutely. But that's what the job looks like when you actually love what you do.
