Balderton's Built in Europe campaign launched this week, highlighting the breadth, potential and, frankly, receipts of tech founders on this continent. We're proudly European too, and what better way to mark the occasion than a Hackathon on home soil.

We partnered up with customers and friends at Lovable, plus local Implement Consulting Group, for Hack Number 9. 150 tech CFOs building something vibey and majestic. Here's what happened.

How good are Danish vibe coders?

Honestly? Better than the Americans. What the teams built in two hours was some of the strongest work we've seen on the whole tour. Right on par with the best shippers to date: Stockholm.

The builds

Out of 50 builds on the day (big clap for everyone taking part!), we whittled it down to three finalists…

Trackman:

Most sales orgs still run commissions out of spreadsheets and email — one broken formula and reps get underpaid, disputes drag for weeks, and finance never sees what's really owed.

TrackPay kills the spreadsheet. It pulls live data from the ERP, CRM, and Data Lake, so finance, sales, and management all work off the same numbers. Reps track OTE, claimed units, and payout status. Managers approve claims and watch regional trends in one view. Finance owns the commission register, flags disputes, and forecasts payouts across sales scenarios — before a single pound goes out. Every change audit-logged, every plan update write-restricted.

One tool. Three teams. Zero Excel.

Xellia:

For a pharma company the biggest accounts — GPOs, distributors, hospital systems — are also the most tangled, but commercial and finance work off different screens, so reps negotiate blind to AR exposure and finance collects with no commercial context.

The Cockpit puts the whole picture in one place. It pulls AR exposure, payment terms, negotiations, approvals, tenders, and margin simulation straight from their ERP, so commercial and finance see the same real-time view. Role-based screens give the rep, manager, and CFO each their own cut. Approvals run through a workflow with a full audit log, a document vault and email outbox hold the paper trail, and a curated market-news feed flags shortages, regulatory shifts, and competitor moves. An AI assistant sits across all of it.

Flatpay:

Closing the books still comes down to a controller eyeballing thousands of ledger entries for anything that looks wrong. And at scale, things slip through: a misposting, a missed accrual, a number that's quietly off until an auditor finds it months later.

BC Guardian's Flux Engine scans the entire general ledger and benchmarks every account-month against an expected seasonal baseline, then flags whatever deviates, ranked by severity and how material the gap is. In the demo it scanned 21,516 entries across 857 account-months and 68 accounts in Denmark, Germany, and Finland, raising 575 flags against 5 control rules. An AI assistant sits on top, grounded in whatever view you're looking at, so finance can ask which accounts carry the most flags, explain the most material one, or compare exposure by country, all in plain English.

Every anomaly caught before the books close, not after.

And the winner… Xellia! 

The judging panel was esteemed — Jens Antonsen (CFO), three Implement partners, Adam Hede, Nicolai Worziger, and Jacob Steinitz, and Michael Haase (Head of Denmark at Lovable). They gave the big win for the day to the Xellia Key Account Cockpit for the clarity of the problem, the breadth of what it pulled together on live ERP data, and how ready it was to put straight to work. Pricing, negotiating, and collecting on a company's biggest accounts had always meant commercial and finance fighting blind from different screens — this closed the gap in one view.

It wasn't built to win a hackathon. It was built so the people closing the deal and the people collecting on it finally work from the same number. We're sure Xellia are making waves at work this week with the cool new product their zero-code CFO built. In Europe. That's what it's all about.

What's next

The tour heads to London on July 3rd for Hack #10, our last stop before a summer break.
