As a viewer, I'd like to see the original datasource linked. It's not clear if this is a milestone that may be outdated or if it's a current MRR number. I'd also like to know if this is self reported vs. verified by the payment gateway (e.g. Stripe via Baremetrics)
The conversion to base thousands for MRR was also confusing to me. For example, ConvertKit's MRR seemed way off at $220K, then I realized it was $2,200K = $2.2M. Might want to convert those so viewers don't have too or at least add some commas. They may be an outlier though on the Open Startups movement with such a large revenue number.
Overall, it's an interesting list. Thanks for putting it together and for sharing.
