I have a quick suggestion for you: two options you can mitigate this "issue".
Option 1: make it free, up to a certain dataset size. You can harvest interested leads like the gentleman above.
Option 2: (if you don't want to deal with a huge volume) offer it for $50 one-time fee, up to X size, for Y months (e.g. $50, up to 1 GB, valid for 3 months). Nice way to filter qualified leads.
There are variations from the two options above, but I think you can easily get the general idea.
We're leaning towards Option 1: free diffing for datasets < 1M rows. Option 2 seems a bit tricker since we are in a way creating a new tool category and it can be harder to convince someone to pay before they try and understand the value (unlike, say, a BI tool – everyone knows they need some kind).
