Careers
Build the operating system for money-in.
A live product with real customers, and a hard deadline on our side: the EU's ViDA package is moving reporting towards real time across the bloc. We're a three-person team in Espoo looking for the people who'll build it with us. You'll ship, not spectate.
Why join now
Real ownership, a live product, an EU-wide clock.
Founding seat
Real ownership (equity / ESOP) and a domain you own end to end, with no layers between you and the problem.
Users from day one
Fizzy runs on real counters in Finland every trading day. Small enough that what you ship is on one of them that week, and you hear about it from the person using it.
Precision matters
In tax and payments, a wrong number is a legal issue, not a bug. We build accordingly.
Currently hiring.

- ▪Are self-directed and comfortable owning a domain in a small team

Sales Lead (our first sales hire)
Espoo / Finland · Full-timeYou'll be the company's first sales hire. Until now every customer was won by the founders; after you, that's your job. Two products, two motions: Fizzy is sold to the person behind the register, Baslic to that same owner and to the accounting firm that keeps their books. You inherit the product and the customers already paying for it. The territory, the tempo and the playbook are yours to build.
What you'll do
Sell Fizzy through to installation in the restaurants, cafés and shops in and around Espoo. The demo here isn't a slide deck: it's a card terminal, a printer and a real receipt.
Open the door to accounting firms. Baslic's accountant plan is free, and when a firm adopts the platform its client businesses follow.
Build your own pipeline and keep it honest. There's no manager above you to polish a forecast; your numbers go straight into how we plan the company.
Who we're looking for
- ▪You've sold to small businesses and you know the owner decides, usually after the shutters come down
- ▪Working proficiency in Finnish. Our customers live their day in Finnish, and so does the Tax Administration
- ▪Comfortable in the field. Most of your week happens in front of a counter, not at a desk
Nice to have
- ▪A background in selling point of sale, payments or accounting software
- ▪An existing network among Finnish accounting firms
What we offer
Base salary plus uncapped commission. We calibrate the model together during your first quarter
The real upside of being first: the person who writes the playbook leads the team once it exists
Direct work with the founders, with no layers in between
No cover letter. Tell us instead about the hardest thing you've ever sold.
