By targetting fixed price we are making sure we have our same priorities over all our customers and thus we will be able to give better customer support to all.

Also, We wont be targetting big enterprises so we can always have a choice of improving our product not by just adding more and more features like other typical enterprise software but making it more simpler and user-friendly always.

At last, maintaining our system simpler will help us targetting masses(SMBs).

I agree the Fixed price is hard to monetize but companies like Todoist have fixed pricing model and still able to have valuations near to about $800 million.
