This is our introductory pricing that will evolve over time. Here is our dilemma - on one hand we want to target indie developers, side projects, bootstrapped startups (that are cost conscious) and on the other hand we want to maximize the earning potential and also not look like a low value product.
The utility of what you are offering is significant. If I'm a 'cost conscious' startup and I need CSV upload functionality then I either write the functionality myself (30+ hours of dev time + ongoing maintenance?) or I use your service.
If the product works as advertised, you could charge $19/month for a basic plan and that will always be better value than 30+ hrs of time a developer will have to put into the CSV problem with all its annoying edge cases.
My suggestion is to modify the free plan such that users can upload 10k+ rows per upload, but only 20-30 times per month. Then your 'cost conscious' startup with only 5 customers can test your solution, know that it works for non-trivial amounts of data, and happily fork out $19/month when they hit 20+ customers a month and become less 'cost conscious'.
