I live in Helsinki and have tried this service a couple of times. Every time I have had the whole van for myself, except once there was a journalist doing a story on the fancy new service. It's not really fair to compare the price to a single bus ride: if you live in Helsinki and don't own a car, you already have a monthly ticket and the incremental cost of getting on a bus is zero. This is in effect a cheap taxi that's a little less convenient.

What I think they're really doing is getting around Finland's taxi permit system (there's a limited number of taxi permits so there is no real competition) by building a taxi-like service that can only pick you up and drop you off at bus stops, which apparently avoids getting the vans classified as taxis.
