I'm pretty sure that the majority of Roon users are monthly subscribers, but let's assume that half are and that all monthly subscribers pay annually (best price), and that Roon gets no revenue from its other products, certifications, or partners. Just to keep things simple and not be too optimistic.
150,000 x $149 = 22.4 million revenue annually, worst case. Compared to Harman (~11 billion revenue), Roon is a tiny company. Compared to others in the audio industry that cater to audiophiles, I would
guess that makes them one of the big boys. More interesting to me would be to know if they were profitable, but that info is not publicly available AFAICT.
