In my case a free tier is not practical so its either be free for a period of time to build critical mass or charge. Its classified ads so the MRR duration is on average 6-9 months so sucess is in always attracting new ads as old ones expire but you need ads to attract potential buyers and potential buyers to attract new ads.. I see the wisdom of getting the ad churn in motion with free ads but I worry that if that works then the site is built on free and will just take a nose dive when I try to start charging and I need to charge. Anyone dealt with anything similar? #business source
