NanoBus.fi will also start operating between Helsinki, Lahti and Jyväskylä from 4 December.
Route traffic is focused on the weekend, once on Fridays and twice on Sundays.
Travel time from Helsinki to Jyväskylä is 3 hours, the company's press release states.
If the passenger wants a distance to other passengers, on the Nanobus trip you can book the next seat empty starting from 2.99 euros.
- We are now trying to bring cheap tickets all over Finland.
With this opening, you can travel from Helsinki to Jyväskylä for less than ten, to Turku for five euros.
Hopefully next year there will be many more destinations, says the company's CEO Henri Autio in a press release.
Nanobus started its low-cost bus business on the Helsinki-Turku route in August.
Nanobus said at the time that one way to keep ticket prices low is to operate only on profitable days.
Currently, the capital Turku is scheduled from Thursday to Sunday.
Behind the company are brothers Henri and Eero Autio.
Henri Autio is studying economics at the University of Turku and Eero Autio is studying energy and environmental technology at Aalto University in Otaniemi.
- The business idea has been born little by little.
We originally planned to start at the beginning of the year, but Korona moved it to this point, the company's CEO Henri Autio told Ilta-Sanomat in the late summer.
